1.2 DEFINITIONS
The following denitions are used in this manual for explaining various electrical concepts,
specications and operations:
Peak Value: It is the maximum value of electrical parameter like voltage / current.
RMS (Root Mean Square) Value: It is a statistical average value of a quantity that varies in
value with respect to time. For example, a pure sine wave that alternates between peak values
of Positive 169.68V and Negative 169.68V has an RMS value of 120 VAC. Also, for a pure sine
wave, the RMS value = Peak value ÷ 1.414.
Voltage (V), Volts: It is denoted by “V” and the unit is “Volts”. It is the electrical force that
drives electrical current (I) when connected to a load. It can be DC (Direct Current – ow in
one direction only) or AC (Alternating Current – direction of ow changes periodically). The AC
value shown in the specications is the RMS (Root Mean Square) value.
Current (I), Amps, A: It is denoted by “I” and the unit is Amperes – shown as “A”. It is the
ow of electrons through a conductor when a voltage (V) is applied across it.
Frequency (F),
Hz: It is a measure of the number of occurrences of a repeating event per unit
time. For example, cycles per second (or Hertz) in a sinusoidal voltage.
Efciency, (η): This is the ratio of Power Output ÷ Power Input.
Phase Angle, (φ): It is denoted by “φ” and species the angle in degrees by which the current
vector leads or lags the voltage vector in a sinusoidal voltage. In a purely inductive load, the
current vector lags the voltage vector by Phase Angle (φ) = 90°. In a purely capacitive load, the
current vector leads the voltage vector by Phase Angle, (φ) = 90°. In a purely resistive load, the
current vector is in phase with the voltage vector and hence, the Phase Angle, (φ) = 0°. In a load
consisting of a combination of resistances, inductances and capacitances, the Phase Angle (φ) of
the net current vector will be > 0° < 90° and may lag or lead the voltage vector.
Resistance (R), Ohm, : It is the property of a conductor that opposes the ow of current
when a voltage is applied across it. In a resistance, the current is in phase with the voltage. It is
denoted by “R” and its unit is “Ohm” - also denoted as “”.

SECTION 1 | Safety Instructions & General Information
Inductive Reactance (XL), Capacitive Reactance (XC) and Reactance (X): Reactance is the
opposition of a circuit element to a change of electric current or voltage due to that element’s
inductance or capacitance. Inductive Reactance (X
any change of electric current through the coil. It is proportional to frequency and inductance
and causes the current vector to lag the voltage vector by Phase Angle (φ) = 90°. Capacitive reactance (X
proportional to the frequency and capacitance and causes the current vector to lead the voltage

> XC and capacitive if XC > XL.

L
Impedance, Z: It is the vectorial sum of Resistance and Reactance vectors in a circuit.
Active Power (P), Watts: It is denoted as “P” and the unit is “Watt”. It is the power that is
consumed in the resistive elements of the load. A load will require additional Reactive Power
for powering the inductive and capacitive elements. The effective power required would be the
Apparent Power that is a vectorial sum of the Active and Reactive Powers.
Reactive Power (Q), VAR: Is denoted as “Q” and the unit is VAR . Over a cycle, this power is
alternatively stored and returned by the inductive and capacitive elements of the load. It is not
consumed by the inductive and capacitive elements in the load but a certain value travels from
the AC source to these elements in the (+) half cycle of the sinusoidal voltage (Positive value) and
the same value is returned back to the AC source in the (-) half cycle of the sinusoidal voltage
(Negative value). Hence, when averaged over a span of one cycle, the net value of this power is 0.
However, on an instantaneous basis, this power has to be provided by the AC source. Hence, the
inverter, AC wiring and over current protection devices have to be sized based on the combined
effect of the Active and Reactive Powers that is called the Apparent Power.

L
and XC is “Ohm” - also denoted as “”.
L
Apparent Power (S), VA: This power, denoted by “S”, is the vectorial sum of the Active
Power in Watts and the
Reactive Power in “VAR”. In magnitude, it is equal to the RMS value of
voltage “V” X the RMS value of current “A”. The Unit is VA. Please note that Apparent Power
VA is more than the Active Power in Watts. Hence, the inverter, AC wiring and over current
protection devices have to be sized based on the Apparent Power.
Maximum Continuous Running AC Power Rating: This rating may be specied as “Active
Power” in Watts (W) or “Apparent Power” in Volt Amps (VA). It is normally specied in “Active
Power (P)” in Watts for Resistive type of loads that have Power Factor =1. Reactive types of
loads will draw higher value of “Apparent Power” that is the sum of “Active and Reactive
Powers”. Thus, AC power source should be sized based on the higher “Apparent Power”
ating in (VA) for all Reactive Types of AC loads. If the AC power source is sized based on the
R
lower “Active Power” Rating in Watts (W), the AC power source may be subjected to overload
conditions when powering Reactive Type of loads.
Starting Surge Power
Rating: Certain loads require considerably higher Starting Surge Power
for short duration (lasting from tens of millisecs to few seconds) as compared to their Maximum
Continuous Running Power Rating. Some examples of such loads are given on next page:
Page 8
SECTION 1 | Safety Instructions & General Information
• Electric Motors: At the moment when an electric motor is powered ON, the rotor is
stationary (equivalent to being “Locked”), there is no “Back EMF” and the windings draw
a very heavy starting current (Amperes) called “Locked Rotor Amperes” (LRA) due to low
DC resistance of the windings. For example, in motor driven loads like Air-conditioning and
Refrigeration Compressors and in Well Pumps (using Pressure Tank), LRA may be as high as
10 times its rated Full Load Amps (FLA) / Maximum Continuous Running Power Rating. The
value and duration of LRA of the motor depends upon the winding design of the motor
and the inertia / resistance to movement of mechanical load being driven by the motor. As
the motor speed rises to its rated RPM, “Back EMF” proportional to the RPM is generated
in the windings and the current draw reduces proportionately till it draws the running FLA /
Maximum Continuous Running Power Rating at the rated RPM.
Transformers (e.g.

Tungsten has a very high Positive Temperature Coefcient of Resistance i.e. it has lower
resistance when cold and higher resistance when hot. As Tungsten heating element will be
cold at the time of powering ON, its resistance will be low and hence, the device will draw
very heavy Starting Surge Current with consequent very heavy Starting Surge Power with a
value of up to 8 times the Maximum Continuous Running AC Power.
• AC to DC Switched Mode Power Supplies (SMPS): This type of power supply is used
as stand-alone power supply or as front end in all electronic devices powered from Utility
/ Grid e.g. in audio/video/ computing devices and battery chargers (Please see Section
4 for more details on SMPS). When this power supply is switched ON, its internal input
side capacitors start charging resulting in very high Inrush Current for a few millisecs

Watts to the Apparent Power (S) in VA. The maximum value is 1 for resistive types of loads
where the Active Power (P) in Watts = the Apparent Power (S) in VA. It is 0 for purely inductive
or purely capacitive loads. Practically, the loads will be a combination of resistive, inductive and
capacitive elements and hence, its value will be > 0 <1. Normally it ranges from 0.5 to 0.8.
Load: Electrical appliance or device to which an electrical voltage is fed.
Linear Load: A load that draws sinusoidal current when a sinusoidal voltage is fed to it. Examples
are, incandescent lamp, heater, electric motor, etc.
N
on-Linear Load: A load that does not draw a sinusoidal current when a sinusoidal voltage is
fed to it. For example, non-power factor corrected Switched Mode Power Supplies (SMPS) used
in computers, audio video equipment, battery chargers, etc.
Resistive Load: A device or appliance that consists of pure resistance (like lament lamps, cook
tops, toaster, coffee maker etc.) and draws only Active Power (Watts) from the inverter. The
inverter can be sized based on the Active Power rating (Watts) of the Resistive Load without
creating overload (except for resistive loads with Tungsten based heating element like lament

Reactive Load: A device or appliance that consists of a combination of resistive, inductive and
capacitive elements (like motor driven tools, refrigeration compressors, microwaves, computers,
audio/ video etc.). The Power Factor (PF) of this type of load is < 1 e.g. AC Motors (PF = 0.4 to
0.8), AC to DC Switch Mode Power Supplies (PF = 0.5 to 0.6), Transformers (PF = 0.8) etc. These
devices require Apparent Power (VA) from the inverter to operate. The Apparent Power is a vectorial sum of Active Power (Watts) and Reactive Power (VAR). The inverter has to be sized based on
the higher Apparent Power (VA) and also based on the Starting Surge Power.

Fig 1.1 Pure and Modied Sine Waveforms for 230VAC, 50 Hz
The 230VAC output waveform of the EvolutionTM series inverters is a Pure Sine Wave like the
waveform of Utility / Grid power. Please see Sine Waveform represented in the Fig. 1.1 that also
shows equivalent Modied Waveform for comparison.
In a Sine Wave, the voltage rises and falls smoothly with a smoothly changing phase angle and
also changes its polarity instantly when it crosses 0 Volts. In a Modied Sine Wave, the voltage
rises and falls abruptly, the phase angle also changes abruptly and it sits at 0V for some time
before changing its polarity. Thus, any device that uses a control circuitry that senses the phase
(for voltage / speed control) or instantaneous zero voltage crossing (for timing control) will not
work properly from a voltage that has a Modied Sine Waveform.
Also, as the Modied Sine Wave is a form of Square Wave, it is comprised of multiple Sine Waves
of odd harmonics (multiples) of the fundamental frequency of the Modied Sine Wave. For example, a 50 Hz Modied Sine Wave will consist of Sine Waves with odd harmonic frequencies of 3rd
Page 10
i
SECTION 1 | Safety Instructions & General Information
(150 Hz), 5th (250 Hz), 7th (350 Hz) and so on. The high frequency harmonic content in a Modied Sine Wave produces enhanced radio interference, higher heating effect in inductive loads like
microwaves and motor driven devices like hand tools, refrigeration / air-conditioning compressors,
pumps etc. The higher frequency harmonics also produce overloading effect in low frequency
capacitors due to lowering of their capacitive reactance by the higher harmonic frequencies. These
capacitors are used in ballasts for uorescent lighting for Power Factor improvement and in singlephase induction motors as start and run capacitors. Thus, Modied and Square Wave Inverters
may shut down due to overload when powering these devices.

SECTION 1 | Safety Instructions & General Information
1.3.4 Electro-Magnetic Interference (EMI) and EMC Compliance
These inverters contain internal switching devices that generate conducted and radiated
electromagnetic interference (EMI). The EMI is unintentional and cannot be entirely eliminated.
The magnitude of EMI is, however, limited by circuit design to acceptable levels as per limits laid
down in the European EMC Directive 2014/30/EU for Class A limits. These limits are designed to
provide reasonable protection against harmful interference when the equipment is operated in a residential environment. These inverters can conduct and radiate radio frequency energy and, if
not installed and used in accordance with the instruction manual, may cause harmful interference
to radio communications. The effects of EMI will also depend upon a number of factors external
to the inverter like proximity of the inverter to the EMI receptors, types and quality of connecting
wires and cables etc. EMI due to factors external to the inverter may be reduced as follows:
•Ensure that the inverter is rmly grounded to the Ground System of the building or the vehicle.
•Locate the inverter as far away from the EMI receptors like radio, audio and video devices
as possible.
•Keep the DC side wires between the battery and the inverter as short as possible.
•Do NOT keep the battery wires far apart. Keep them taped together to reduce their
inductance and induced voltages. This reduces ripple in the battery wires and improves
performance and efciency.
•Shield the DC side wires with metal sheathing / copper foil / braiding.
•Use coaxial shielded cable for all antenna inputs (instead of 300 ohm twin leads).
•Use high quality shielded cables to attach audio and video devices to one another.
•Limit operation of other high power loads when operating audio / video equipment.
1.3.5 Characteristics of Switch Mode Power Supplies (SMPS)
Switch Mode Power Supplies (SMPS) are extensively used to convert the incoming AC power into
various voltages like 3.3V, 5V, 12V, 24V etc. that are used to power various devices and circuits
used in electronic equipment like battery chargers, computers, audio and video devices, radios
etc. These power supplies use large capacitors in their input section for ltration. When the
power supply is rst turned on, there is a very large inrush current drawn by the power supply as
the input capacitors are charged (The capacitors act almost like a short circuit at the instant the
power is turned on). The inrush current at turn-on is several to tens of times larger than the rated
RMS input current and lasts for a few milliseconds. An example of the input voltage versus input
current waveforms is given in Fig. 1.2. It will be seen that the initial input current pulse just after
turn-on is > 15 times larger than the steady state RMS current. The inrush dissipates in around 2
or 3 cycles i.e. in around 40 to 60 milliseconds for 50 Hz sine wave.
Further, due to the presence of high value of input lter capacitors, the current drawn by an SMPS
(With no Power Factor correction) is not sinusoidal but non-linear as shown in Fig 1.3. The steady
state input current of SMPS is a train of non-linear pulses instead of a sinusoidal wave. These
pulses are two to four milliseconds duration each with a very high Crest Factor of around 3. Crest
Factor is dened by the following equation: CREST FACTOR = PEAK VALUE ÷ RMS VALUE
Many SMPS units incorporate “Inrush Current Limiting”. The most common method is the NTC
(Negative Temperature Coefcient) resistor. The NTC resistor has a high resistance when cold
and a low resistance when hot. The NTC resistor is placed in series with the input to the power
supply. The higher cold resistance limits the input current as the input capacitors charge up. The
input current heats up the NTC and the resistance drops during normal operation. However,
if the power supply is quickly turned OFF and back ON, the NTC resistor will be hot so its low
resistance state will not prevent an inrush current event.

The inverter should, therefore, be sized adequately to withstand the high inrush current and the
high Crest Factor of the current drawn by the SMPS. Normally, inverters have short duration Surge
Power Rating of 2 times their Maximum Continuous Power Rating. Hence, it is recommended
that for purposes of sizing the inverter, to accommodate Crest Factor of 3, the Maximum Continuous Power Rating of the inverter should be > 2 times the Maximum Continuous Rated Power of the SMPS. For example, an SMPS rated at 100 Watts should be
powered from an inverter that has Maximum Continuous Power Rating of > 200 Watts.

SECTION 1 | Safety Instructions & General Information
Lead-acid batteries can be categorized by the type of application:
Automotive service - Starting/Lighting/Ignition (SLI, a.k.a. cranking), and
1.
Deep cycle service.
2.
Deep Cycle Lead Acid Batteries of appropriate capacity are recommended for powering of inverters.
1.4.1 Deep Cycle Lead Acid Batteries
Deep cycle batteries are designed with thick-plate electrodes to serve as primary power sources,
to have a constant discharge rate, to have the capability to be deeply discharged to up to 80 %
capacity and to repeatedly accept recharging. They are marketed for use in recreation vehicles
(RV), boats and electric golf carts – so they may be referred to as RV batteries, marine batteries
or golf cart batteries. Use Deep Cycle batteries for powering inverters.
1.4.2 Rated Capacity Specied in Ampere-hour (Ah)
Battery capacity “C” is specied in Ampere-hours (Ah). An Ampere is the unit of measurement for
electrical current and is dened as a Coulomb of charge passing through an electrical conductor
in one second. The Capacity “C” in Ah relates to the ability of the battery to provide a constant
specied value of discharge current (also called “C-Rate” - see page 17) over a specied time in
hours before the battery reaches a specied discharged terminal voltage (Also called “End Point
Voltage”) at a specied temperature of the electrolyte. As a benchmark, the automotive battery
industry rates batteries at a discharge current or C-Rate of C/20 Amperes corresponding to 20 Hour
discharge period. The rated capacity “C” in Ah in this case will be the number of Amperes of current
the battery can deliver for 20 Hours at 80ºF (26.7ºC) till the voltage drops to 1.75V / Cell. i.e. 10.5V
for 12V battery or 21V for 24V battery. For example, a 100 Ah battery will deliver 5A for 20 Hours.
1.4.3 Rated Capacity Specied in Reserve Capacity (RC)
Battery capacity may also be expressed as Reserve Capacity (RC) in minutes typically for
automotive SLI (Starting, Lighting and Ignition) batteries. It is the time in minutes a vehicle can
be driven after the charging system fails. This is roughly equivalent to the conditions after the
alternator fails while the vehicle is being driven at night with the headlights on. The battery
alone must supply current to the headlights and the computer/ignition system. The assumed
battery load is a constant discharge current of 25A.
Reserve capacity is the time in minutes for which the battery can deliver 25 Amperes at 80ºF
(26.7ºC) till the voltage drops to 1.75V / Cell i.e. 10.5V for 12V battery or 21V for 24V battery.
Approximate relationship between the two units is: Capacity “C” in Ah = Reserve Capacity in
RC minutes x 0.6

SECTION 1 | Safety Instructions & General Information
Electrical energy is stored in a cell / battery in the form of DC power. The value of the stored
energy is related to the amount of the active materials pasted on the battery plates, the surface
area of the plates and the amount of electrolyte covering the plates. As explained above, the
amount of stored electrical energy is also called the Capacity of the battery and is designated by
the symbol “C”.
The time in Hours over which the battery is discharged to the “End Point Voltage” for purposes
of specifying Ah capacity depends upon the type of application. Let us denote this discharge
time in hours by “T”. Let us denote the rate of discharge current of the battery as a multiple of
Ah capacity "C" and call it as the "C-Rate”. If the battery delivers a very high discharge current,
the battery will be discharged to the “End Point Voltage” in a shorter period of time. On the
other hand, if the battery delivers a lower discharge current, the battery will be discharged to
the “End Point Voltage” after a longer period of time. Mathematically, C-Rate is dened as:
“C-RA

20 Hour discharge period i.e. C/20 Amps.

1.4.7 Reduction in Usable Capacity at Higher Discharge Rates – Typical in
Inverter Application
As stated earlier, the Ah capacity of automotive battery is normally applicable at a discharge rate
of 20 Hours. As the discharge rate is increased as in cases where the inverters are driving higher
capacity loads, the usable Ah capacity reduces due to “Peukert Effect”. This relationship is not
linear but is more or less according to the Table 1.9.

Table 1.9 shows that a 100 Ah capacity battery will deliver 100% (i.e. full 100 Ah) capacity if it
is slowly discharged over 20 Hours at the rate of 5 Amperes (50W output for a 12V inverter and
100W output for a 24V inverter). However, if it is discharged at a rate of 50 Amperes (500W
output for a 12V inverter and 1000W output for a 24V inverter) then theoretically, it should
provide 100 Ah ÷ 50 = 2 Hours. However, Table 1.9 above shows that for 2 Hours discharge
rate, the capacity is reduced to 50% i.e. 50 Ah. Therefore, at 50 Ampere discharge rate (500W
output for a 12V inverter and 1000W output for a 24V inverter) the battery will actually last for
50 Ah ÷ 50 Amperes = 1 Hour.
1.4.8 State of Charge (SOC) of a Battery – Based on “Standing Voltage”
The “Standing Voltage” of a battery under open circuit conditions (no load connected to it)
can approximately indicate the State of Charge (SOC) of the battery. The “Standing Voltage”
is measured after disconnecting any charging device(s) and the battery load(s) and
letting the battery “stand” idle for 3 to 8 hours before the voltage measurement is
taken. Table 1.10 shows the State of Charge versus Standing Voltage for a typical 12V/24V
battery system at 80°F (26.7ºC).

Check the individual cell voltages / specic gravity. If the inter-cell voltage difference is more
than a 0.2V, or the specic gravity difference is 0.015 or more, the cells will require equalization.
Please note that only non-sealed / vented / ooded / wet cell batteries are equalized.
Do not equalize sealed / VRLA type of AGM or Gel Cell Batteries.
1.4.9 State of Discharge of a Loaded Battery – Low Battery / DC Input Voltage
Alarm and Shutdown in Inverters
Most inverter hardware estimate the State of Discharge of the loaded battery by measuring
the voltage at the inverter’s DC input terminals (considering that the DC input cables are thick
enough to allow a negligible voltage drop between the battery and the inverter).
Inverters are provided with a buzzer alarm to warn that the loaded battery has been deeply
discharged to around 80% of the rated capacity. Normally, the buzzer alarm is triggered
when the voltage at the DC input terminals of the inverter has dropped to around
10.5V for a 12V battery or 21V for 24V battery at C-Rate discharge current of C/5
Amps and electrolyte temp. of 80°F. The inverter is shut down if the terminal voltage at C/5
discharge current falls further to 10V for 12V battery or 20V for 24V battery.
The State of Discharge of a battery is estimated based on the measured terminal voltage of the
battery. The terminal voltage of the battery is dependent upon the following:
emperatur
- T
reactions inside the battery and produces a Negative Voltage Coefcient – during charging /
discharging, the terminal voltage drops with rise in temperature and rises with drop in temperature
- The amount of discharging current or “C-Rate”: A battery has non linear internal resistance
and hence, as the discharge current increases, the battery terminal voltage decreases non-linearly
e of the battery electrolyte: Temperature of the electrolyte affects the electrochemical
The discharge curves in Fig. 1.4 show the % State of Charge versus the terminal voltage of
typical Flooded Lead Acid Battery under different charge /discharge currents, i.e. “C-Rates”

1.4.10 Low DC Input Voltage Alarm in Inverters
As stated earlier, the buzzer alarm is triggered when the voltage at the DC input terminals of
the inverter has dropped to around 10.5V for a 12V battery or 21V for 24V battery at C-Rate
discharge current of C/5 Amps. Please note that the terminal voltage relative to a particular State
of Discharge decreases with the rise in the value of the discharge current. For example, terminal
voltages for a State of Discharge of 80% (State of Charge of 20%) for various discharge currents
will be as given at Table 1.11 (Refer to Fig. 1.4 for parameters and values shown in Table 1.11):
Table 1.11 TERMINAL VOLTAGE AND SOC OF LOADED BATTERY
SECTION 1 | Safety Instructions & General Information
In the example given above, the 10.5V / 21.0V Low Battery / DC Input Alarm would trigger
at around 80% discharged state (20% SOC) when the C-Rate discharge current is C/5 Amps.
However, for lower C-Rate discharge current of C/10 Amps and lower, the battery will be almost
completely discharged when the alarm is sounded. Hence, if the C-Rate discharge current
is lower than C/5 Amps, the battery may have completely discharged by the time the
Low DC Input Alarm is sounded.
1.4.11 Low DC Input Voltage Shut-down In Inverters
As explained above, at around 80% State of Discharge of the battery at C-Rate discharge
current of around C/5 Amps, the Low DC Input Voltage Alarm is sounded at around 10.5V for
a 12V battery (at around 21V for 24V battery) to warn the user to disconnect the battery to
prevent further draining of the battery. If the load is not disconnected at this stage, the batteries
will be drained further to a lower voltage and to a completely discharged condition that is
harmful for the battery and for the inverter.
Inverters are normally provided with a protection to shut down the output of the inverter if the
DC voltage at the input terminals of the inverter drops below a threshold of around 10V for a
12V battery (20V for 24V battery). Referring to the Discharge Curves given in Fig 1.4, the State
of Discharge for various C-Rate discharge currents for battery voltage of 10V / 20V is as follows:
(Please note that the X-Axis of the curves shows the % of State of Charge. The % of State of
Discharge will be 100% - % State of Charge):
85% State of Discharge (15% State of Charge) at very high C-rate discharge current of C/3 Amps.
-
- 100% State of Discharge (0 % State of Charge) at high C-Rate discharge current of C/5 Amps.
- 100% discharged (0% State of charge) at lower C-rate Discharge current of C/10 Amps.
It is seen that at DC input voltage of 10V / 20V, the battery is completely discharged for C-rate
discharge current of C/5 and lower
In view of the above, it may be seen that a xed Low DC Input Voltage Alarm is not
useful. Temperature of the battery further complicates the situation. All the above analysis is
based on battery electrolyte temperature of 80°F. The battery capacity varies with temperature.
Battery capacity is also a function of age and charging history. Older batteries have lower
capacity because of shedding of active materials, sulfation, corrosion, increasing number of
charge / discharge cycles etc. Hence, the State of Discharge of a battery under load cannot be
estimated accurately. However, the low DC input voltage alarm and shut-down functions are
designed to protect the inverter from excessive current drawn at the lower voltage.
1.4.12 Depth of Discharge of Battery and Battery Life
The more deeply a battery is discharged on each cycle, the shorter the battery life. Using more
batteries than the minimum required will result in longer life for the battery bank. A typical cycle
life chart is given in the Table 1.12 below:

1.4.14 Sizing the Inverter Battery Bank
One of the most frequently asked questions is, “how long will the batteries last?” This question
cannot be answered without knowing the size of the battery system and the load on the
inverter. Usually this question is turned around to ask “How long do you want your load to
run?”, and then specic calculation can be done to determine the proper battery bank size.
There are a few basic formulae and estimation rules that are used:
1.
Active Power in W
2. For an inverter running from a 12V battery system, the approximate DC current required
from the 12V batteries is the AC power delivered by the inverter to the load in Watts (W)
divided by 10 & for an inverter running from a 24V battery system, the approximate DC
current required from the 24V batteries is the AC power delivered by the inverter to the
load in Watts (W) divided by 20.
3.
Energy r
The rst step is to estimate the total AC watts (W) of load(s) and for how long the load(s) will operate in hours (H). The AC watts are normally indicated in the electrical nameplate for each appliance or equipment. In case AC watts (W) are not indicated, Formula 1 given above may be used
to calculate the AC watts. The next step is to estimate the DC current in Amperes (A) from the AC
watts as per Formula 2 above. An example of this calculation for a 12V inverter is given below:
Let us say that the total AC W
Then, using
= 1000W ÷10 = 100 Amperes, or by 24V batteries = 1000W ÷ 20 = 50A.
ext, the energy required by the load in Ampere Hours (Ah) is determined.
N
For example, if the load is to operate for 3 hours then as per Formula 3 above, the energy to be
delivered by the 12V batteries = 100 Amperes × 3 Hours = 300 Ampere Hours (Ah), or by the
24V batteries = 50A x 3 Hrs = 150 Ah.
ow, the capacity of the batteries is determined based on the run time and the usable
N
capacity.
rom Table 1.9 “Battery Capacity versus Rate of Discharge”, the usable capacity at 3 Hour
F
discharge rate is 60%. Hence, the actual capacity of the 12V batteries to deliver 300 Ah will be
equal to: 300 Ah ÷ 0.6 = 500 Ah, and the actual capacity of the 24V battery to deliver 150 Ah
will be equal to 150 Ah ÷ 0.6 = 250 Ah.
And nally, the actual desired rated capacity of the batteries is determined based
on the fact that normally only 80% of the capacity will be available with respect to the rated
capacity due to non availability of ideal and optimum operating and charging conditions. So the
nal requirements will be equal to:
FOR 12V BATTERY: 500 Ah ÷ 0.8 = 625 Ah (note that the actual energy required by the load
was 300 Ah).
FOR 24V BATTERY: 250 Ah ÷ 0.8 = 312.5 Ah (Note that the actual energy required was 150 Ah).
equired from the battery = DC current to be delivered (A) x Time in Hours (H).
Formula 2 above, the approximate DC current to be delivered by the 12V batteries
atts (W) = Voltage in Volts (V) x Current in Amperes (A) x Power Factor
atts deliver
ed by the inverter = 1000W.
20 | SAMLEX AMERICA INC.
Page 21
SECTION 1 | Safety Instructions & General Information
It will be seen from the above that the nal rated capacity of the batteries is almost 2 times
the energy required by the load in Ah. Thus, as a Rule of Thumb, the Ah capacity of the
batteries should be twice the energy required by the load in Ah.
1.14.15 Charging Batteries
Batteries can be charged by using good quality AC powered battery charger or from alternative
energy sources like solar panels, wind or hydro systems. Make sure an appropriate Battery
Charge Controller is used. It is recommended that batteries may be charged at 10% to 20%
of their Ah capacity (Ah capacity based on 20 Hr Discharge Rate). Also, for complete charging
(return of 100% capacity), it is recommended that 4-Stage Charger may be used as follows:
Normal Charging (3-Stages)
Stage 1 (Bulk Stage at constant current) " Stage 2 (Absorption Stage at constant
voltage) " Stage 3 (Float Stage at constant voltage)
Equalization Charging (4-Stages)
Stage 1 (Bulk Stage at constant current) " Stage 2 (Absorption Stage at constant voltage) "
Stage 3 (Equalization Stage at constant voltage) " Stage 4 (Float Stage at constant voltage)

3.4 INSTALLING BATTERIES - SERIES AND PARALLEL CONNECTION
Batteries are normally available in voltages of 2V, 6V and 12V and with different Ah capacities.
A number of individual batteries can be connected in series and in parallel to form a bank of
batteries with the desired increased voltage and capacity.

or 24V Charger
Cable “B”
When two or more batteries are connected in series, their voltages add up but their Ah capacity
remains the same. Fig. 3.5 shows 4 pieces of 6V, 200 Ah batteries connected in series to form a
battery bank of 24V with a capacity of 200 Ah. The Positive terminal of battery 4 becomes the
Positive terminal of the 24V bank. The Negative terminal of battery 4 is connected to the Positive
terminal of battery 3. The Negative terminal of battery 3 is connected to the Positive terminal of
battery 2. The Negative terminal of battery 2 is connected to the Positive terminal of battery 1.
The Negative terminal of battery 1 becomes the Negative terminal of the 24V battery bank.

3.4.4 Wiring Order in Parallel Connection of Batteries
CAUTION!
When 2 or more batteries / battery strings are connected in parallel and are then connected
to inverter/charger (See Figs 3.6 and 3.7), attention should be paid to the manner in which
the inverter/charger is connected to the battery bank. Please ensure that if the Positive output
cable of the inverter/charger (Cable “A”) is connected to the Positive battery post of the rst
battery (Battery 1 in Fig 3.6) or to the Positive battery post of the rst battery string (Battery
1 of String 1 in Fig. 3.7), then the Negative output cable of the inverter/charger (Cable “B”)
should be connected to the Negative battery post of the last battery (Battery 4 as in Fig. 3.6) or
to the Negative Post of the last battery string (Battery 4 of Battery String 2 as in Fig. 3.7).
This connection ensures the following:
- The resistances of the interconnecting cables will be balanced.
- All the individual batteries / battery strings will see the same series resistance.
- All the individual batteries will charge/discharge at the same charging/discharging
current and thus, will be charged/discharged to the same state at the same time.
- None of the batteries will see an overcharge/overdischarge condition.
If the Positive output cable of the inverter/charger (Cable “A”) is connected to the Positive
battery post of the rst battery (Battery 1 in Fig. 3.6) or to the Positive battery post of the rst
battery string (Battery 1 of String 1 in Fig. 3.7), and the Negative output cable of the inverter/
charger (Cable “B”) is connected to the Negative battery post of the rst battery (Battery 1 as
in Fig. 3.6) or to the Negative Post of the rst battery string (Battery 1 of Battery String 1 as in
Fig 3.7), the following abnormal conditions will result:
- The resistances of the connecting cables will not be balanced.
- The individual batteries will see different series resistances.
- All the individual batteries will be charged/discharged at different charging/discharging
current and thus, will reach fully charged/discharged state at different times.
- The battery with lower series resistance will take shorter time to charge/discharge as
compared to the battery which sees higher series resistance and hence, will experience
over charging/over discharging and its life will be reduced.

Quand il y a 2 batteries/ls de batterie ou plus qui sont liés en parallèle et branché à la fois, à un chargeur (Voir Figs. 3.6
et 3.7), il faut faire attention à la manière dont le chargeur est branché à la banque de batterie. Veuillez assurer que le
câble positif de sortie du chargeur de batterie (Câble A) est lié à la borne positive de la première batterie (La batterie 1
dans la Fig. 3.6) ou à la borne positive de batterie qui est liée au premier l (Le l 1 et la batterie 1, Fig 3.7), et puis le
câble négatif de sortie du chargeur de batterie (Câble B) est lié à la borne négative de la dernière batterie (La Batterie 4
dans la Fig. 3.6) ou à la borne négative de batterie qui est liée au dernier l (Le l 2 et La batterie 4 dans la Fig. 3.7).
Cette connexion assure la suivante:
- Les résistances des câbles interconnectés seront équilibrées
- Tous les batteries/ ls de batterie dans la série auront la même résistance
- Toutes les batteries individuelles vont recharger au même courant, ainsi elles seront rechargées à l’état pareille, au
même temps
- Aucune des batteries auront une condition de surcharge.
Si le câble positif de sortie du chargeur de batterie (Câble A) est lié à la borne positive de la première batterie (La batterie
1 dans la Fig. 3.6) ou à la borne positive de batterie qui est liée au premier l (Le l 1 et La Batterie 1, Fig 3.7), et puis le
câble négatif de sortie du chargeur de batterie (Câble B) est lié à la borne négative de la première batterie (La batterie 1
dans la Fig. 3.6) ou à la borne négative de batterie qui est liée au premier l (Le l 1 de La Batterie 1 dans la Fig. 3.7), les
conditions anormales résulteront:
- Les résistances des câbles interconnectés seront pas équilibrées
- Tous les batteries/ ls de batterie dans la série n’auront pas la même résistance
- Toutes les batteries individuelles vont recharger à des courants différentes, ainsi elles atteindront un état de
rechargement complèt mais en décalage.
- La batterie ayant le moins de résistance dans la série prendrait moins de temps pour être rechargée comparé aux
autres batteries. Alors elle serait surchargée et, en conséquence aurait une vie plus courte.

3.5.1 Preventing DC Input Over Voltage
It is to be ensured that the DC input voltage of this unit does not exceed 17 VDC for the 12V battery
version EVO-2212E and EVO-3012E, and 35 VDC for the 24V battery versions EVO-2224E and EVO-4024E
to prevent permanent damage to the unit.
3.5.2 Preventing Reverse Polarity On The Input Side
!
CAUTION!
When making battery connections on the input side, make sure that the polarity of battery
connections is correct (Connect the Positive of the battery to the Positive terminal of the unit
and the Negative of the battery to the Negative terminal of the unit). If the input is connected
in reverse polarity, external DC fuse in the input side will blow and may also cause permanent
damage to the inverter.
Damage caused by reverse polarity is not covered by warranty.

input terminals. As soon as the DC input connection loop (Battery (+) terminal →
Fuse → Positive input terminal of EVO
Battery (–) terminal) is completed, these capacitors will start charging and the unit will
momentarily draw very heavy current that will produce sparking on the last contact in
the input loop even when the unit is in powered down condition.
Ensure that the fuse is inserted only after all the connections in the loop have been
completed so that sparking is limited to the fuse area.
Flow of electric current in a conductor is opposed by the resistance of the conductor. The resistance
of the conductor is directly proportional to the length of the conductor and inversely proportional to
its cross-section (thickness). The resistance in the conductor produces undesirable effects of voltage
drop and heating. The size (thickness / cross-section) of the conductors is designated in mm
AWG (American Wire Gauge). Conductors thicker than AWG #4/0 are sized in MCM/kcmil.
Conductors are protected with insulating material rated for specic temperature e.g. 90˚C/194˚F. As
current ow produces heat that affects insulation, there is a maximum permissible value of current
(called “Ampacity”) for each size of conductor based on temperature rating of its insulation. The
insulating material of the cables will also be affected by the elevated operating temperature of the
terminals to which these are connected. Ampacity of cables is based on British Standard BS7671.
Please see details given under “Notes for Table 3.1”.
The DC input circuit is required to handle very large DC currents and hence, the size of the
cables and connectors should be selected to ensure minimum voltage drop between the battery
and the inverter. Thinner cables and loose connections will result in poor inverter performance
WARNING!
he input section of the inverter has large value capacitors connected across the

and will produce abnormal heating leading to risk of insulation melt down and re. Normally,
the thickness of the cable should be such that the voltage drop due to the current & the
resistance of the length of the cable should be less than 2%. Use oil resistant, multi-stranded
copper wire cables rated at 90º C minimum. Do not use aluminum cable as it has higher
resistance per unit length. Cables can be bought at a marine / welding supply store.
Effects of low voltage on common electrical loads are given below:
• Lighting circuits - incandescent and Quartz Halogen: A 5% voltage drop causes an
approximate 10% loss in light output. This is because the bulb not only receives less power,
but the cooler lament drops from white-hot towards red-hot, emitting much less visible light.
• Lighting circuits - uorescent: Voltage drop causes a nearly proportional drop in light
output.
• AC induction motors - These are commonly found in power tools, appliances, well pumps
etc. They exhibit very high surge demands when starting. Signicant voltage drop in these
circuits may cause failure to start and possible motor damage.
attery charging circuits - These are critical because voltage drop can cause a
• B
disproportionate loss of charge current to charge a battery. A voltage drop greater than 5%
can reduce charge current to the battery by a much greater percentage.

ATTENTION!
Des dégats causés par un renversement des polarités n’est pas couverts par la garantie.
Quand vous faites des connexions à la batterie du côté d’entrée, veuillez assurer que les polarités sont mise du bon côté
(Lié le positif de la batterie à la borne positive de l’appareil et le négatif de la batterie à la borne négative de l’appareil. Si
les polarité de l’entrée sont mise à l’envers, le fusible CC externe du côté d’entrée va s’exploser et peut causer des dégâts
permanent à l’onduleur.

ATTENTION!
La section d’entrée de l’onduleur a des condensateurs de grande valeur qui sont connecté aux bornes d’entrées. Tant que
le boucle de connexion d’entrée CC (la borne (+) de la batterie → le fusible la borne → d’entrée positive du EVOTM → la

L’appareil prendra un courant fort brièvement pour s’alimenter qui va produire une étincelle sur le dernier contact du
boucle d’entrée même si l’interrupteur ON/OFF du l’onduleur est dans la position OFF.

Le ux du courant dans un conducteur est opposé par la résistance du conducteur. La résistance du conducteur est
corrélative à la longueur du conducteur et inversement corrélatif à son diamètre (l’épaisseur). La résistance dans un
conducteur produit des effects indésirables comme une perte de tension et une surchaffe. La taille (l’épaisseur) des
conducteurs est classée par le AWG (American Wire Guage). Les conducteurs qui sont plus épais que la taille AWG #4/0
sont classé par MCM/kcmil.
Les conducteurs sont protègés par des matériaux isolants classés pour une température spécique, par exemple,une
température de 90˚C/194˚F. Le ux de courant produit de la chaleur et affecte l’isolation. Alors, il y a une valeur de
courant maximale (aussi appellé « L’ampacité ») qui est permise pour chaque taille de conducteur et pour la classication

(NEC)-2014. « Notes for table 3.1 »
Le circuit d’entrée CC doit subir à des courants CC forts et ainsi, il faut que la taille des câbles et des connecteurs
est sélectionnée pour réduire la perte de tension entre la batterie et l’onduleur. Avec des câbles moins épais et des
connexions lâches la performance de l’onduleur est diminuée et en plus, ça pourrait produire une réchauffement
anormale qui risque de fondre l’isolation ou commencer un incendie. Normalement, il faut que le câble soit assez épais
pour réduire la perte de tension, dû au courant/ la résistance du câble, à moins que 2%. Utilisez des câble multiliares
(ls en cuivre et résistant à l’huile) qui sont classés au moins à 90º C. N’utilisez pas des câbles en aluminium car ils ont une
résistance plus haute (par la longueur de l’unité). On peut achèter des câbles aux magasins de fournitures pour marin/
soudage.

3.5.4 Fuse Protection In The Battery Circuit
A battery is an unlimited source of current. Under short circuit conditions, a battery can supply
thousands of Amperes of current. If there is a short circuit along the length of the cables that
connects the battery to the inverter, thousands of Amperes of current can ow from the battery
to the point of shorting and that section of the cable will become red-hot, the insulation will
melt and the cable will ultimately break. This interruption of very high current will generate a
hazardous, high temperature, high-energy arc with accompanying high-pressure wave that
may cause re, damage nearby objects and cause injury. To prevent occurrence of hazardous
conditions under short circuit conditions, the fuse used in the battery circuit should limit the

WA
•In "Inverting Mode" (default condition), the Neutral of the AC output of the unit
gets bonded to the metal chassis of the unit through the internal “Neutral to Chassis
Switching Relay” (Relay K4 in Fig 4.1).
•In “Charging Mode”, the internal “Output Neutral to Chassis Switching Relay”
disconnects the Neutral of the AC output connection from the chassis of the unit. The
Neutral of the AC output connection of the unit will get bonded to the Earth Ground
through the Neutral to Earth Ground bond in the AC Breaker Panel/Load Center
supplying Grid power / AC output connections of the generator.
•Disabling Neutral to Ground Bond: In some applications, the Output Neutral may be
required to remain isolated from chassis/Ground at all times. For this, automatic Output
Neutral to chassis Ground bond can be disabled by disconnecting the Male/Female
Disconnect (13, Fig 3.9) located in the AC Wiring Compartment.
•System grounding, as required by National / Local Electrical Codes / Standards, is the
responsibility of the user / system installer.

3.6.3 Preventing Paralleling of the AC Output
WA
RNING!
The AC output of the unit cannot be synchronized with another AC source and hence, it is
not suitable for paralleling on the output side. The AC output of the unit should never be
connected directly to an electrical breaker panel / load center which is also fed from another
AC source. Such a connection may result in parallel operation of different power sources
and AC power from the other AC source will be fed back into the unit which will instantly
damage the output section of the unit and may also pose a re and safety hazard. If an
electrical breaker panel / load center is fed from this unit and this panel is also required to be
powered from additional alternate AC source, the AC power from the additional AC source
should rst be fed to a suitable Manual/Automatic Transfer Switch and the output of the
transfer switch should be connected to the electrical breaker panel / load center. To prevent
possibility of paralleling and severe damage to the inverter, never use a simple jumper cable
with a male plug on both ends to connect the AC output of the inverter to a handy wall
receptacle in the home / RV.
ATTENTION!
La sortie de courant alternatif de l’unité ne peut pas être synchronisée avec une autre source de courant alternatif et,
par conséquent, il ne convient pas pour mise en parallèle du côté de la sortie. La sortie AC de l’unité ne doit jamais
être connecté directement à un panneau central / de charge disjoncteur électrique qui est également alimenté par
une autre source de courant alternatif. Une telle connexion peut entraîner un fonctionnement parallèle de différentes sources d’énergie et la puissance AC de l’autre source de courant alternatif est réinjecté dans l’unité qui va instantanément endommager la section de sortie de l’unité et peuvent aussi poser un risque d’incendie et de sécurité.
Si un centre panneau de disjoncteur électrique / charge est alimentée à partir de cette unité et ce panneau est également nécessaire pour être alimenté à partir de suppléant supplémentaire source de courant alternatif, l’alimentation
de la source de courant alternatif supplémentaire doit d’abord être introduit dans un manuel approprié / commutateur de transfert automatique et le sortie du commutateur de transfert doit être relié au centre panneau / de la
charge électrique du disjoncteur. Pour éviter possibilité de mise en parallèle et de graves dommages à l’onduleur, ne
jamais utiliser un câble de raccordement simple avec une che mâle sur les deux extrémités pour raccorder la sortie
AC de l’onduleur à une prise murale à portée de main à la maison / RV.

3.10 RESIDUAL CURRENT DEVICE (RCD) PROTECTION FOR 230VAC MOTORHOME
/ CARAVAN APPLICATION
When this unit is installed in 230VAC motorhome / caravan, ensure that appropriate capacity of Residual Current Device (RCD) is used in the vehicle wiring system to protect all load
circuits. (Refere to Fig 3.14)
3.11 GROUNDING TO EARTH OR TO OTHER DESIGNATED GROUND
Grounding means connecting (bonding) to Earth Ground or to other designated Ground.
F
or example, in a motorhome / caravan / RV, the metal frame of the motorhome / caravan /
RV is normally designated as the Negative DC Ground. Similarly, all metal portions of boats /
marine craft are bonded together and called Boat Ground.
Grounding is required for (i) protection against damage due to lightning strike and (ii)
protection against electric shock due to “Ground Fault”. In case of EVO
TM
, “Ground Fault”
may occur due to inadvertent contact between an energized ungrounded current carrying
conductor and exposed metal surface resulting in voltage getting fed to (i) the metal chassis
of the EVO
TM
or (ii) to the metal chassis of the devices connected to EVOTM or (iii) to the metal
frame/ chassis in a motorhome / caravan. When this energized exposed surface is touched,
the voltage will drive current through the body to Earth Ground producing electric shock.
When properly grounded to Earth Ground (or Frame / Chassis Ground in motorhome or caravan), the Leakage Current Protection Device (like RCD, GFCI etc.) or Over Current Protection
Device (like Circuit Breaker or Fuse) will trip and interrupt the circuit feeding power from the
AC source (EVO
TM
/ Grid / Generator) or the DC source (12V / 24V battery). Proper grounding
will ensure that all exposed metal surfaces will have equal potential and will be bonded to (i)
a single common Earth Ground point i.e. the Ground Rod / buried metallic water / gas pipe at
the premises or (ii) the Frame / Chassis Ground in a motorhome / caravan.

For proper operation of the Residual Current Device (RCD) on the output side of the
generator, it is to be ensured that the Neutral of the generator is either bonded internally
to the frame / chassis of the generator or externally to the Earthing Terminal “EG” on
the generator. This will create a Neutral to Earth Ground bond in the generator (Neutral
of generator " Frame / chassis of generator " Earthing Terminal “EG” on the generator

that if a ground fault occurs, leakage current is able to return back to the Neutral of
generator winding through the Earth ground path for tripping of the RCD.
For Typical Mobile Installation (Please refer to Fig. 3.14)

EVOTM being used. The wire size used for DC side grounding should be minimum 10mm2 or of
the same size as the battery cable, whichever is thicker (Battery cable size should have minimum Ampacity ≥ the Ampere rating of this battery fuse (150A to 400A) depending upon the
model of the EVOTM being used). This recommendation on sizing of the DC Side Ground-
ing Wire will be superseded by the National / Local Electrical Codes.
!
CAUTION!
As per American Boat and Yacht Council (ABYC) Safety Standard E-11 for the AC and DC
Electrical Systems on Boats, the size of DC side grounding wire shall not be smaller than one
size under that required for current carrying conductors supplying the device. Hence, for application on EVOTM on boat / yacht, the size of the DC side grounding conductor should be of
the same or one size smaller than the size of battery cable specied in Table 3.1.
!
ATTENTION!
Conformément « American Boat et Yacht Council » ( ABYC ) la norme de sécurité E - 11 , la taille du l de mise a terre du côté
CC ne doit pas être inférieure à un format sous celle requise pour les conducteurs tenant le courant pour alimenter l'appareil.
Par conséquent, pour l’application EVOTM sur le bateau / yacht, la taille du conducteur de mise a terre côté CC devrait être de la
même ou strictement une taille plus petite que la taille du câble de batterie indiqué dans le tableau 3.1.
INFO
As described at Section 3.13, the metal frame / chassis of the EVOTM (Fig 3.12, G1) is bonded to
the Main Earthing Terminal “ME” for AC side grounding. It may be argued that if the metal frame
/ chassis of EVO
is it necessary to provide an additional DC side grounding wiring? (Wiring that bonds DC Grounding Terminals "GE", "PE-B" and "ME" in Fig 3.1). If separate thicker grounding wire of the same
size as the battery cable was not provided for the DC side grounding and there was a ground fault
in the battery circuit, very large DC fault current from Battery+ would ow through the smaller
size AC grounding wires to the Battery Negative through the Main Earthing Terminal “ME”. These
smaller size AC side grounding wires would be damaged due to very high DC side fault current
(150A to 400A depending on the Model of the EVO
TM

Multiple Earthing (PME) or “TN-C-S” Earthing System (Please refer to Fig. 3.12)
A DC Side Grounding Connector (G2) (5 in the DC side layout in Fig. 2.1) is provided in the

3.14.1 Switching of Bonding of Output Neutral To Chassis Ground
Automatic Output Neutral to Chassis Ground bond switching arrangement has been provided
in these units through “Output Neutral to Chassis Ground Bond Switching Relay” [K4 in
F
ig 4.1] to switch bonding of the Output Neutral Terminal of the Inverter Charger as follows:
When operating as an inverter, the current carrying conductor of the Inverter Section that is
connected to the Output Neutral Terminal of the Inverter Charger is bonded to the metal
chassis of the inverter by the “Output Neutral to Chassis Ground Bond Switching Relay”
[K4 in Fig 4.1]. As the metal chassis of the inverter is in turn bonded to the “Chassis
of the motorhome / caravan / vehicle or to the Boat Ground (DC Negative Grounding Bus
Bar and the Main AC Grounding Bus Bar are tied together in a boat and this is called the
“Boat Ground”), this current carrying conductor of the Inverter Section (connected to the
Output Neutral Terminal) will become the Grounded Conductor (GC) or the Neutral of the
Inverter Section.
When in Charging Mode, the Neutral conductor of the Grid power/Generator will be
connected to the Output Neutral Terminal of the Inverter Charger. At the same time, the
“Output Neutral to Chassis Ground Bond Switching Relay” [K4 in Fig 4.1] will unbond
(disconnect) the Output Neutral connector of the Inverter Charger from the chassis of the
Inverter Charger. This will ensure that the Grounded Conductor (GC) / Neutral of the Grid
power/Generator is bonded to the Earth Ground at one single point at the location of the
AC Power Distribution System of the Motorhome and Caravan Park / Marina.
Disabling Neutral to Ground Bond: In some applications, the Output Neutral may be
required to remain isolated from the chassis/Ground at all times. For this, automatic Ouput
Neutral to Chassis Ground bond can be disabled by disconnecting the Male/Female Quick
Disconnect located in the AC wiring compartment. [Please see (i) 13, Fig 3.9 and (ii) "QD"
in Fig 4.1]

3.16.2 Requirement Of Deep Cycle, Auxiliary Battery And Battery Isolator For
Powering Inverters In Mobile Installations
Basic information on Lead Acid Batteries is given in Section 1.4 under "General
I
nformation - Lead Acid batteries".
For details, read on-line White Paper titled “Batteries, Chargers & Alternator” at:
www.samlexamerica.com (Home > Support > White Papers).
A motorhome / caravan / vehicle has Starter, Lighting and Ignition (SLI) battery. As explained in
White Paper titled “Batteries, Chargers and Alternators”, SLI batteries are designed to produce
high power in short bursts for cranking.
SLI batteries use lots of thin plates to maximize the surface area of the plates for providing very
large bursts of current (also specied as Cranking Amps). This allows very high starting current but
causes the plates to warp when the battery is cycled. Vehicle starting typically discharges 1%–3%
of a healthy SLI battery’s capacity. The automotive SLI battery is not designed for repeated deep
discharge where up to 80% of the battery capacity is discharged and then recharged. If an SLI
battery is used for this type of deep discharge application, its useful service life will be drastically
reduced. Hence, this type of battery is not recommended for the storage of energy for inverter
applications. A second deep cycle auxiliary battery must be installed in the motorhome / caravan /
vehicle for powering the EVO
When the second auxiliary deep cycle battery is used, a Battery Isolator is required that will allow parallel connection of the two batteries for charging when the alternator is ON and disconnecting the parallel connection when the alternator is stopped (Isolator is shown in Fig. 3.14).
The capacity of the Battery Isolator should be as follows:
For EVO-2012E: The maximum continuous DC current required is 266A. The capacity of
the Battery Isolator should be more than 266A or more than the capacity of the alternator,
whichever is higher
For EVO-2224E: The maximum continuous DC current required is 133A. The capacity of
the Battery Isolator should be more than 133A or more than the capacity of the alternator,
whichever is higher

3.16.3 Requirement To Keep The Neutral Conductor Of Shore Power Isolated
From The Chassis Ground Of The Motorhome / Caravan / Vehicle
As per Section 721 of British Standard BS 7671 : 2008 the Neutral conductor in electrical
installations in motorhomes / caravans / vehicles is NOT bonded to the "chassis
the motorhome / caravan / vehicle. The Neutral is oating with respect to the "chassis
This is necessary for safety because if the Neutral was bonded to the chassis of the RV and if
the Neutral and the Hot got reversed by mistake, the chassis of the R
V will be at 230 V
respect to the Earth Ground. If a person standing on the Earth Ground touches the chassis of the
RV, he will be fed with 230 VAC and will receive electrical shock!
3.16.4 Typical Mobile Installation
Fig. 3.14 illustrates a typical installation on motorhome / caravan / vehicle using 230VAC, 16A

SECTION 4 | General Description & Principles of Operations
4.1 GENERAL DESCRIPTION
EVOTM is a Pure Sine Wave, Bi-directional, Single-Phase Inverter / Charger with a Transfer Relay
that operates either as an inverter OR as a smart battery charger. It uses a common Converter
Section that can work in two directions – in one direction it converts external AC power to DC
power to charge the batteries using Grid or Generator (Charging Mode) and in the other direction, it converts DC power from the battery to AC power (Inverting Mode). This allows the same
power components to be used in both directions resulting in high-energy transfer efciency with
fewer components. Please note that it can NOT work in both the directions at the same time (i.e.
it cannot work as an inverter and as a charger at the same time).
High performance 100 MHz DSP (Digital Signal Processing) type of micro-controller and Pulse
Width Modulated (PWM) conversion circuits are used for the above implementation.
4.2 COMPONENTS OF THE SYSTEM
It consists of 3 Sections – Inverter Section, Battery Charger Section and AC Input/Transfer Relay
Section. The unit is fed with the following inputs:
Up to 2 exter
Grid if both Grid and Generator inputs are available at the same time
DC Battery Source consisting of 12V/24V battery bank. 4 versions of EVO
2 versions for 12 VDC battery input (EVO-2212E and EVO-3012E) & 2 for 24 VDC battery
input (EVO-2224E and EVO-4024E)
Additional external charging source: The output of the external charger of up to 50A
capacity is routed through this unit and operates in parallel with the internal charger. The
internal charging current is controlled to ensure that the combined current fed to the battery
does not exceed the programmed Bulk Charging Current. This improves the life of the
battery. Please see Section 5.4 for more details.
nal AC input power sources – Grid or Generator or both with PRIORITY for
TM
are available.
4.3 INVERTER SECTION
The Inverter Section is a heavy-duty, continuous rated, DSP micro-controller based inverter generating
a Pure Sine Wave output of 230 VAC, 50 Hz / 60 Hz (50 Hz default) from the DC Battery Source. It is
able to supply AC power to various types of AC loads such as resistive loads (heaters, incandescent
lamps etc) or reactive loads (motors, air conditioners, refrigerators, vacuum cleaners, fans, pumps,
Switched Mode Power Supplies (SMPS) used in audio / video equipment and computers, etc.).
4.3.1 Principle of working of Inverter Section
The low DC voltage from the DC Battery Source is inverted to the AC voltage in two steps. The low
DC voltage from the DC Battery Source is rst converted to low frequency (50 Hz or 60 Hz ; 50 Hz
default), low voltage synthesized sine wave AC using an H-bridge conguration and high frequency
PWM (Pulse Width Modulation) technique. The low frequency, low voltage synthesized sine wave
is then stepped up to 230 VAC pure sine wave voltage using a low frequency Isolation Transformer
and ltration circuit. This type of DC to AC inversion is called Hybrid Type – a combination of low
frequency and high frequency implementation. Other distinctive features of the Inverter Section are
given below:
Soft Start: The inverter design incorporates “Soft Start” feature with the following advantages and protections:
58 | SAMLEX AMERICA INC.
Page 59
SECTION 4 | General Description & Principles of Operations
- When the unit powers up, it starts in Inverting Mode rst. The output voltage ramps up
gradually from around 96 VAC to 230 VAC in around 200 ms. This reduces otherwise very
high starting inrush current drawn by AC loads like Switched Mode Power Supplies (SMPS)
and motor driven loads like fans, pumps, compressors etc. This will result in lower motor
inrush current (which typically can be up to 650% of the full load current of the motor),
which means lesser mechanical stresses, wear and tear and increased lifetime of the motor,
coupling and fan. Additionally, the impact on the load side components is greatly reduced,
meaning less likelihood of causing problematic voltage drops during starting.
Power Surge – Up to 300%:
-
The inverter is able to deliver very high surge power / curr
by 200% for 100 ms. This range of high instantaneous power is delivered at the rated voltage
and hence, it is able to provide very high starting torque for difcult motor driven loads like
compressors and pumps that require higher Locked Rotor Current during startup.
-
If the power drawn by the load exceeds the above surge ratings, the inverter pr
itself by limiting the load current to 300% / 200% which results in reduction of
output voltage and consequent reduction in load current. The output voltage recovers
automatically when power drawn by the load drops below the above surge limits
Power Boost up to 150%: Higher percentage of rated power can be provided for limited
time periods as follows:
• 150% for 5 sec
• 140% for 30 sec
• 120% for 5 min
• 110% for 30 min
ent of up to 300% for 1 ms followed
otects
4.4 DIRECT DUAL AC INPUT ARCHITECTURE
For higher reliability and redundancy, direct AC input from Grid and Generator can be fed
simultaneously to separate AC Input Circuits. Only one AC source is selected at one time. When
both Grid and Generator are available simultaneously, Grid is given priority. Transfer from Grid
to Generator or from Generator to Grid is always routed through the inverter. Please see details
under “Synchronized Transfer of Power”.
4.5 TRANSFER RELAY SECTION
Transfer Relay Section is used to either feed AC power to the Battery Charger Section and at
the same time, pass through the AC power from the external AC input power source to the
load (As long as the external AC input power from Grid/Generator is available and is within the
programmed limits of voltage and frequency) or to transfer the load to the Inverter Section (In
case of loss of the external AC input power source or if this source is not within the programmed
limits of voltage and frequency). Typical transfer time is 16 milliseconds from Grid/Generator to
Inverter and <1ms from Inverter to Grid/Generator. Heavy duty 40A, Transfer Relay is used for
reliable transfer of up to 300% surge power and for Neutral to Ground Bond Switching.
4.5.1 AC Transfer and Output Neutral To Chassis Ground Bond Switching
Automatic switching of bonding between the Ouput Neutral and Chassis Ground has been provided in EVO
Switching of bonding is carried out as follows:
TM
through “Output Neutral to Chassis Ground Bond Switching Relay” (K4 in Fig 4.1).

• Disabling Neutral to Ground Bond: In some applications, the Output Neutral of EVO
may be required to remain isolated from the chassis/Ground at all times. For this, automatic
Output Neutral to Ground bond can be disabled by disconnecting the Male/Female Quick

4.5.2 Operation of Transfer Relay and Output Neutral to Chassis Ground
Bond Switching Relay
Refer to Schematic at Fig 4.1.
The Bi-directional Transformer is used as follows:
o Feeds AC output from the Inverter Section when Grid / Generator power is not available.
o Feeds Grid / Generator power to the Battery Charger Section when Grid / Generator are
available.
Switching of Hot Output (OUTPUT LINE)
o 40A rated SPDT Relays K2 and K3 are used to switch the Hot Output Connector
(OUTPUT LINE) to either the Inverter Section or to Grid / Generator
o When Grid / Generator Power is available, relays K2 or K3 will be energized and contact
4 switches over to contact 5 (Grid has PRIORITY over Generator if both are present
simultaneously). The Bidirectional Transformer works as a battery Charger. The Hot AC
input from the Grid (GRID LINE) or from the Generator (GEN LINE) is fed to the Hot input
Bi-directional Transformer for battery charging and at the same time, it is passed
of the
through to the Hot Out (OUTPUT LINE) for powering the AC loads
o
When Grid / Generator power fails, relays K2 / K3 will be de-energized and contact 4
switches back to contact 3. Output from the Inverter Section is fed to the
Bi-directional
Transformer and onwards to the Hot Out (OUTPUT LINE) for powering the AC loads

4.5.3 Synchronized Transfer of Power
Direct AC input from Grid and Generator can be fed simultaneously to separate AC Input
Circuits. Only one AC source is selected at one time. When both Grid and Generator are
available simultaneously, Grid has priority. To facilitate synchronization, transfer of power
from Grid to Generator or from Generator to Grid is always routed through the inverter.
4.5.4 Transfer From Inverter to Grid / Generator
When Grid / Generator becomes available, its voltage and frequency are checked if these
are within the programmed limits. If yes, the output voltage of the Inverter Section is
synchronized with Grid / Generator through Phase Locked Loop” (PLL). This synchronization
process takes few seconds. Once synchronization is completed, the load is transferred
instantly (within 1 ms) to Grid / Generator at Zero Crossing of the voltage waveform for
seamless transfer and for better protection of Transfer Relay contacts. The unit now operates
in “Charging Mode” with the AC power from the Grid / Generator charging the batteries as
well as providing power to the AC loads.
4.5.5 Transfer From Grid / Generator to Inverter
When the unit is operating in “Charging Mode” with the AC power from the Grid /
Generator charging the batteries as well as providing power to the AC loads, the phase and
frequency of Grid / Generator are tracked continuously. In case Grid / Generator fails or is
disconnected, the inverter will be forced into transfer at voltage which is at the same phase
and frequency at which Grid / Generator had been disconnected. Load will be transferred to
the inverter within 16ms at zero crossing. The unit will now work in “Inverting Mode” and
the batteries will start discharging.
4.5.6 Transfer Between Grid and Generator
As discussed in “Transfer from Inverter to Grid/Generator” above, the EVOTM prioritizes the
Grid over the Generator input. If the EVO
the Grid input is restored, the EVO
transfer back to the Grid input. Both operations are synchronized and the transfer is at the
zero crossing for a seamless transfer.

4.6 BATTERY CHARGER SECTION
The Battery Charger Section of these units is a powerful, 3/4 Stage, fully automatic battery
charging circuit. The same Isolation Transformer and the H-Bridge conguration are used to work
in the reverse direction, ie. rectify the AC voltage from the Primary AC Power Source to PWM
controlled low voltage DC to charge the DC Battery Source. That is why it is called a Bi-directional
device. Normal 3-Stage Charging Mode consists of Bulk, Absorption and Float stages (Default).
4-Stage Equalization Mode consists of Bulk, Absorption, Equalization and Float. (The Equalization
Mode is selectable). Equalization Mode is desirable for the proper health of Wet Cell Batteries.
Further, the charging voltages and currents are programmable to take care of a wide range of
battery types like ooded, AGM, Gel Cell, Lead Calcium, etc.
Important battery charging features are as follows:
• Adaptive Charging Control
• Dynamic Input Power Diversion Control
• Parallel charging through External Charge Controller
• Temperature compensated charging

SECTION 4 | General Description & Principles of Operations
4.8 MODES OF OPERATION
4.8.1 Charging Mode
As long as the external AC input power from the Grid/Generator is available and is within the
programmed limits of voltage and frequency, it is passed through to the AC load through the
Transfer Relay Section. At the same time, the Battery Charger Section converts the external AC
input power from the Grid/Generator to DC power to charge the DC Battery Source.
4.8.2 Inverting Mode
If at any instant, the external AC input power from the Grid/Generator is interrupted or is not
within the programmed limits of voltage and frequency, the Transfer Relay is de-energized and
the load is transferred to the Inverter Section and internal battery charging is terminated. This is
called the Inverting Mode.
4.8.3 Power Saving Mode
When the unit is operating without any load connected to it, it requires some minimum input power
from the battery to keep all the sections inside the unit alive and ready to deliver power to the AC
load as soon as the load is switched on. This power is called the “No Load Power Draw” or the “Idle
Power” or “Self Power Consumption”. The “No Load Power Draw” of these units in the Normal
Mode is around 25W to 30W. The EVO
if required (Applicable only when the unit is in “Inverter Mode”). This is achieved by enabling the
“Power Saving Mode”. The unit is shipped in default “Disabled” condition i.e. Power Saving Mode will be NOT active. Optional Remote Control EVO-RC (see Appendix A) is required to disable this mode. When this mode is enabled, the unit does not provide continuous output power. A
pulsing output power consisting of only 3 cycles of reduced 48 VAC output voltage that are made
available every 0.5 seconds is used to sense if a minimum load is present or not. As continuous
power is not being supplied, the “No Load Power Draw” is reduced to less than 8W
load greater than the programmed value of “Wake-up Point” is sensed, the unit exits Power Save
Mode and starts providing normal continuous output power. If the load drops to the programmed
value of “Enter Point”, the unit once again reverts to Power Saving Mode. Programmable and
Default Values of “Enter Point” and “Wake-up Point” are shown in Table 6.6. Further details are
available in the Owners Manual for the Remote Control EVO-RC (See Appendix A).
Power Saving Mode should be disabled for the following loads:
Low power loads that draw < 5W e.g. digital clocks, satellite r
machines etc.
Audio / video / computing devices that consume normal operating power > 50 W but draw less than
5W on entering Sleep Mode when switched off or when no activity is seen for a specied time.
4.8.4 Power Saving Mode - Transfer Characteristics in Grid / Generator Mode
•Transfer from Grid / Generator to Inverter: If qualied Grid or Generator AC input
power is available (its voltage and frequency are within the programmed range), the
Transfer Relay remains energized and the AC input power is passed through to the
load and at the same time, the unit operates as a battery charger. If AC input power
from Grid / Generator fails or is not qualied (its voltage and frequency are not within
the programmed range), the Transfer Relay is de-energized and the load is transferred
to the inverter. When this transfer takes place, the inverter initially operates in Normal
Mode. If the AC load was greater than the programmed value of “Wake-up Point”,
the inverter continues in Normal Mode. However, if it sees a load less than the
programmed value of “Enter Point” for around 5 sec, it enters Power Saving Mode.

SECTION 4 | General Description & Principles of Operations
•Transfer from Inverter to Grid / Generator: As soon as qualied AC input power
from Grid / Generator is available, the inverter will exit Power Saving Mode and will
switch over to Normal Mode. This switch over is necessary for synchronizing the AC
output of the inverter with the AC input before transfer (Synchronization can not be
carried out with pulsing wave form during Power Saving Mode). After synchronization
is completed, the load is transferred to the Grid/Generator at zero crossing of the
voltage waveform.
4.8.5 Ofine / Online UPS Modes
IN
FO
Description given below provides general capability of this function. For details of
programming, please refer to sub-headings “ONLINE MODE” and "ONLINE OPTION" at
Section 4.4 in the Owner’s Manual for Remote Control Model EVO-RC at Appendix A.
The EVO
TM
is able to operate in two modes – Ofine Mode and Online Mode. Ofine Mode is
the Default Mode. Mode can be changed to Online Mode through optional Remote Control
Model EVO-RC (Please see Section 4.4 in the attached Owner’s Manual for EVO-RC –
Appendix A).
Ofine Mode: This is the Default Mode. In this mode, the AC input from the Grid /
Generator is the PRIMARY source of AC power and the batteries / Inverter Section of EVO
TM
is
the BACK-UP source of DC-AC power. If qualied AC input (within the programmed voltage
and frequency limits) is available at the Grid / Generator AC input, the Transfer Relay will be
switched ON (energized), the EVO
TM
will operate in “Charging Mode” and qualied AC input
from the Grid / Generator will be passed through to the AC output and at the same time, the
Internal AC Charger will start charging the battery. If an external charger is also connected
to the External Charging Terminals (3 and 4, Fig 2.1), the internal AC Charger will limit the
charging current to a value = (Programmed Value of Charging Current – Value of Current
fed from the external charger). When the Grid / Generator AC input fails or, is not within
the programmed values of voltage and frequency, the Transfer Relay will be switched OFF
(de-energized), the unit will change over to “Inverting Mode” and the AC Output will be fed
from the internal Inverter Section. When Grid / Generator input is restored, the unit will revert
back to “Charging Mode” to charge the batteries and at the same time, pass through the AC
input to the AC output.
O
nline Mode: In this mode, the Inverter Section of the EVO
TM
is the PRIMARY DC-AC source
of power. The Grid / Generator is the BACK-UP source of AC power. Online Mode has 2
options of operation that can be programmed through optional Remote Control
Model EVO-RC (Please see Section 4.4 in the attached Owner’s Manual for EVO-RC
– Appendix A). In this mode, even if qualied Grid / Generator AC input is available (within
the programmed voltage and frequency limits), the EVO
TM
always operates in “Inverting
Mode” and AC output is provided by the Inverter Section as long as the battery is in charged
condition above the specied programmed value of low battery voltage (This specied value
of low battery voltage is selected through programmable parameter “LOW VOLT ALARM”).
When the battery discharges to the programmed voltage threshold of “LOW VOLT ALARM”,
or lower and remains at this threshold, or below for a sustained programmed time period,
the Transfer Relay will be switched ON (energized) and the EVO
TM
will change over to
“Charging Mode” [The sustained programmed time period is selected using parameter called
Page 66
SECTION 4 | General Description & Principles of Operations
“GS DETECT TIME” (0-600 sec; Default 10 sec)]. On changing over to “Charging Mode”,
qualied AC input from the Grid / Generator is passed through to the AC Output and at the
same time, the Internal AC Charger starts charging the battery. If an external charger is also
connected to the External Charging Terminals (3 and 4, Fig 2.1), the internal AC Charger will
limit the charging current to a value = (Programmed Value of Charging Current – Value of
Current fed from the external charger). When the battery has been re-charged either fully
through complete, 3-Stage Charging algorithm (Option 1) or, for a programmed specied
time period (Option 2), the Transfer Relay will be switched OFF (de-energized), charging will
stop and the unit will change over to “Inverting Mode”.
4.9 TEMPERATURE SENSOR FOR BATTERY CHARGING
Battery Temperature Sensor Model EVO-BCTS (Fig 2.5) has been provided to ensure optimum
charging by modifying the charging voltages based on temperature if the battery sees very
wide temperature swings. Temperature compensation can be programmed with the help of
optional Remote Control EVO-RC (see Section 4.4 at Appendix A). Range is -3 to -4 mv/ °C/
cell (Default is -4 mv/ °C/cell). Without temperature compensation, the battery life is likely to
be drastically reduced because the battery will be undercharged during cold conditions (will
build up sulfation) or will be overcharged during hot conditions (will boil and lose excessive
water). Please read White Paper titled “Batteries, Chargers & Alternators” available
online at www.samlexamerica.com (Home > Support > White Papers) and Section 5
titled “Battery Charging in EVO
4.10 PARALLEL OPERATION WITH EXTERNAL CHARGE CONTROLLER
The Battery Charger Section is able to operate in parallel with external charger with a charging
capacity of up to 50 A. The output of the external charging source is routed through this unit and
operates in parallel with the internal charger. The internal charging current is controlled to ensure
that the combined current fed to the battery does not exceed the programmed Bulk Charging Current. This improves the life of the battery. Please see Section 5.4 for more details.

4.11.1 Cooling Fans
The unit is cooled by convection and by forced air cooling using 2 variable speed cooling fans.
Temperature is sensed at the Power Transformer and H-Bridge Power Mosfets / Heat Sink. The
fans will be switched ON at specied temperatures measured at the above sense points. The
speed of the fans is increased as the temperature rises.

emote Control EVO-RC at Appendix A. The unit goes to Fault Mode and shuts down due to over
temperature sensed at the Main Power Transformer and the Heat Sink for the Power Mosfets: Fault
messages and temperature thresholds for shut down and auto-reset are as follows:
• “Transformer over heat!” : Shut down at 150C and auto-reset at 80C
• “Heat sink over heat!” : Shut down at 70C and auto-reset at 40C
4.11.3 Automatic Reduction Of Charging Current In Higher Ambient Temperatures
In order to protect against over temperature shut down when operating in higher ambient
temperatures of 50C to 60C, the charging current is automatically reduced as follows based on
temperature sensed at the Power Transformer and at the Heat Sink for the Power Mosfets:
• Power Transformer: In cast the temperature is >130C, the charging current is reduced by
4.12 OPTIONAL REMOTE CONTROL EVO-RC FOR PROGRAMMING OF MODES
OF OPERATION AND PARAMETERS
Optional Remote Control Model EVO-RC [Fig 2.4(a)] will be required for more advanced control
and monitoring. Please see separate Owner’s Manual for EVO-RC at Appendix A. The Remote
Control comes with 10M / 33 ft., RJ-45 Data Cable. The Remote plugs into RJ-45 Jack on the
front panel of the unit (7, Fig 2.1). It has provision for Data Logging using SD Card of up to 16

GB (F
T16 / FAT32). It also has its own Real Time Clock and Super Capacitor Type of Internal
Battery. The Remote Control will be required for Firmware upgrade through the SD Card.
Detailed messaging is available through its LCD display and LEDs. This remote will also be required
for programming of various parameters to suit specic requirements. Each programmable
parameter has a Default Value. This unit has been shipped with the various parameters set

SECTION 5 | Battery Charging in Evolution Series
5.1 PRINCIPLE OF OPERATION OF BATTERY CHARGING SECTION
EVOTM Series is a Bi-directional Inverter / Charger with a Transfer Relay that operates either as
an inverter OR as a battery charger. It uses a common Converter Section that can work in two
directions – in one direction it converts external AC power to DC power to charge the batteries
(Charging Mode) and in the other direction, it converts the DC power from the battery to AC
power (Inverting Mode). PWM design is used for both the charging and inverting sections.
Please note that it cannot work in both the directions at the same time (i.e. it cannot work as
an inverter and as a charger at the same time). High performance, 100 MHz DSP (Digital Signal
Processing) type of micro-controller and Pulse Width Modulated (PWM) conversion circuits are
used for the above implementation.
When AC input power from Grid / Generator is available within the programmed limits of
voltage and frequency, the internal Transfer Relay passes through the AC input to the AC loads
and at the same time, the AC input is fed to the Battery Charger Section.
First, the AC input voltage is stepped down by the Low Frequency Isolation Transformer and
is then rectied by 4 sets of H-Bridge Mosfets and fed to the batteries for charging. When
charging starts, the current does not rise sharply, but ramps up slowly to the full programmed
Bulk Charge curent.
Page 68
SECTION 5 | Battery Charging in Evolution
TM
Series
The Battery Charger Section of the EVOTM is a powerful, 100 MHz DSP micro-controller based, 3
Stage or a 4 Stage Charger. Battery charging parameters are detailed at Table 6.2.
3 Stage Charging Algorithm (Default) is used for normal day to day charging. The 3 stages are
– Bulk, Absorption and Float. The charging voltages and currents are programmable within the
ranges given in Table 6.2 to take care of a wide range of battery types like ooded, AGM, Gel
Cell, Lead Calcium etc. For details, see Section 5.6 and Charging Curves at Fig 6.2.
4 Stage Charging Algorithm is used in the Equalization Mode. Equalization Mode is selected
using optional Remote Control EVO-RC (see Appendix A). This mode is used only for Flooded
or Wet Cell batteries. The 4 stages will be - Bulk, Absorption, Equalization and Float. For details,
see Section 6.2 and Charging Curves at Fig 5.2. Equalization Mode is desirable for the proper
health of Wet Cell Batteries. Equalization voltage is programmable. Equalization current and
Equalization time are computed automatically. Please see Table 6.2 for details.
5.2.1 Dynamic AC Input Current Diversion Control Between AC Pass Through
Current And Battery Charging Current
EVOTM Models have very powerful Battery Charger Section that will require very high AC input
current from the Grid / Generator (See Table 5.1).
TABLE 5.1 CHARGING CURRENTS AND PASS THROUGH LOAD CURRENTS
When batteries are being charged at or near the maximum value of charging current (See TABLE
5.1) and the pass through load current increases, the Grid / Generator supply circuit breaker may
trip if the combined value of the AC side charging current (equivalent to the DC side charging
current) and the pass through load current exceeds the Grid / Generator supply circuit breaker
capacity. This situation is prevented by “Dynamic AC Input Current Diversion Control between AC
Pass through Current and Battery Charging Current”. This is accomplished through appropriate
setting of programmable parameters “GRID MAX CURRENT” / “GEN MAX CURRENT”. Optional
Remote Control Model EVO-RC will be required for the desired setting (Please refer to Section 4.5
and TABLE 4.5 of the attached EVO-RC Owner's Manual at Appendix A).
“GRID MAX CURRENT” / “GEN MAX CURRENT” (Default = 16A) should be set equal to the
Ampere rating of the external Grid / Generator supply breakers. During Battery Charging Mode,
if the AC pass through load current is increased resulting in the net AC input current increasing
to a value more than the programmed “GRID MAX CURRENT” / “GEN MAX CURRENT”, the
TM
EVO
will automatically reduce the charging current to ensure that the equivalent AC
Side Charging Current + Pass Through Load Current is not more than the set value of
“GRID MAX /GEN MAX CURRENT”.
If the AC side charging curr

CURRENT” / “GEN MAX CURRENT” for 5 sec, the EVO

“GRID MAX CURRENT” setting = the Default value of 16A. The “Bulk Charging Current”

0.09A AC side charging current).

DC side charging current). As the “GRID MAX CURRENT” is set at 16A, the AC input side
charging current will be reduced from 9A to 6A (6A AC side charging current corresponds to
66.6A DC side charging current) so that the total AC input current is limited to 16A.

charging current). However, now the AC input current will be 18A. After 5 sec, the EVO
will shut down due to FAULT MODE and display “Input over current!” (AC input current will
be 1A more than the “GRID MAX” current setting of 16A for 5 sec).

5.2.2 Automatic Reduction Of Charging Current In Higher Ambient Temperatures
In order to protect against over temperature shut down when operating in higher ambient
temperatures of 50C to 60C, the charging current is automatically reduced as follows based on
temperature sensed at the Power Transformer and at the Heat Sink for the Power Mosfets:
In case the temperature is >130C, the charging current is reduced by
5.3 ADAPTIVE CHARGING CONTROL FOR COMPLETE CHARGING AND
PREVENTION OF OVER CHARGING / BOILING OF BATTERIES
An automatic Adaptive Charging Algorithm is used to ensure that the battery is completely
charged in a safe manner for longer battery life. In this algorithm, the time the battery remains
in Absorption and Equalization Stages is proportional to the time the battery remains in the
Bulk Charge Stage. A battery that is deeply discharged will remain in Bulk Stage for a longer
duration and will require longer time in the Absorption and Equalization Stages for complete
charging. On the other hand, a battery that is almost completely charged will remain in the
Bulk Stage for a shorter duration and consequently, will remain in Absorption and Equalization
stages for a shorter duration. This will prevent overcharging / boiling of the battery.
Page 70
SECTION 5 | Battery Charging in Evolution
TM
Series
Note: In other inverter chargers that execute Absorption and Equalization Stages for
a xed time of 4 to 8 Hours, a nearly fully charged battery may overcharge / boil and
hence, will reduce battery life.
5.4 PARALLEL CHARGING USING EXTERNAL CHARGER
The batteries feeding the EVOTM can also be charged using appropriately sized external charger.
Output of the external charger is fed to the input terminals marked “EXT Charger” (3,4 in Fig
2.1). Maximum charging current on these terminals is to be limited to 50A. This limit
should not be exceeded!
The charging current received from the external charger is directly fed to the battery terminals
(1,2 in Fig 2.1) through a series connected Hall-effect Current Sensing IC with integrated shunt.
The value of this current is displayed under “BAT EXT” on the optional Remote Control EVO-RC
(Please see display screen in Section 3, Fig 3.2 in the attached Owner’s Manual for EVO-RC: (i)
Row – Screen No. 9; Column – Group 2 and (ii) Row – Screen No. 16; Column – Group 3)
The net Bulk Charging Current fed to the battery bank will, thus, be as follows:
Normally, Lead Acid batteries should not be charged at very high Bulk Charging Current as this
will damage the batteries due to overheating and cell degradation. Normal Bulk Charging Current is in the range of 10% to 20% of the Ah capacity of the battery bank at C/20 Discharge
Rate. Check with the battery manufacturer regarding recommended Bulk Charging Current for
your battery bank. This value of “

The measured value of the charging current received from the external Solar Charge Controller is monitored by the control circuitry of the internal Battery Charging Section. The amount
of Bulk Charging Current produced by the internal Battery Charging Section is adjusted in real
time to satisfy the following condition:

from 40A to 25A so that the net charging current is equal to the programmed value of 40A
In other Inverter Chargers where this design feature is not available and the Bulk Charging
Current of the internal Battery Charger Section is xed, the batteries are likely to be charged at
high Bulk Charging Current = Fixed value of Bulk Charging Current from the internal Battery
Charging Section + Current available from the external charger.

or Negative post [Fig 2.5(b)]. Connect the RJ-45 plug to the Temperature Sensor Jack (6, Fig.

voltages based on temperature if the battery sees very wide temperature swings. In addition to
compensating ABSORPTION, EQUALIZATION AND FLOAT VOLTAGES, the thresholds of “LOW
VOLT ALARM”, “BATT LOW VOLTAGE” shut down, “RESET VOLTAGE” and “BATTERY OVER

gassing. Please see Table 6.2 for details of programmable settings and Default Values. This 3
Stage Charging is the Default "CHARGE MODE" (Refer to parameter "CHARGE MODE" at
Screen No. 12 of Table 4.4 of Owner's Manual for EVO-RC at Apendix A).
Fig. 5.1 shows the voltage and current charging curves with respect to time and different
charging stages.
NOTE: With the optional Remote Control Model EVO-RC (see Owner's Manual at Appendix A), it is
possible to program and activate 4 Stage Charging Mode including the 4th Equalization Stage. 4-Stage
charging is required to be carried out only on ooded / wet cell batteries. This 4 Stage Charging Mode
is discussed separately under “4 Stage Charging Mode in Equalization Mode” at Section 5.7.
5.6.1 Bulk Charge Stage
In the rst stage, known as the "BULK" Charge Stage, the charger delivers the maximum
"BULK CURRENT" (“Io”) that has been programmed through the “Parameter Setting Menu”
of the optional Remote Control Model EVO-RC. Range and Default value are shown at Table
6.2. This current is delivered to the batteries until the battery voltage approaches its Gassing
Voltage i.e. Absorption Voltage (programmed as "ABSORP VOLTAGE"—typically around 14.4
volts for 12 volt batteries and 28.8 volts for 24 volt batteries (again, this voltage can vary based
upon the desired values programmed through the “Parameter Setting Menu” of the optional
Remote Control Model EVO-RC (see Appendix A). The Bulk Charge Stage restores about 75%
of the battery’s charge. The Gassing Voltage is the voltage at which the electrolyte in the battery
begins to break down into Hydrogen and Oxygen gases. Under normal circumstances, a battery
should not be charged at a voltage above its Gassing Voltage (except in the manually selected
Equalization Stage) since this will cause the battery to lose electrolyte and dry out over time.

Voltage Curve
Current Curve
The value of the "BULK CURRENT" (“Io”) depends upon the total Ampere Hour (Ah) capacity
of the battery or bank of batteries. A battery should never be charged at very high charging
current as very high rate of charging will not return the full 100 percent capacity as the Gassing
Voltage rises with higher charging current. As a general Rule of Thumb, the Bulk Charging
Current “Io” should be limited to 10% to 20% of the Ah capacity of the battery (20 Hr
R
ate). Higher charging current may be used if permitted by the battery manufacturer.
Programmable range and Default values of "BULK CURRENT" (“Io”) are shown in Table 6.2.
The units are shipped with the "BULK CURRENT" set at the Default Value of 40A.
When the unit enters Charging Mode, it starts working as a battery charger and the charger
will run at full programmed "BULK CURRENT" until the charger reaches the programmed
Absorption Voltage.
As part of the Adaptive Charging Algorithm, a software timer will measure the time taken from
the instant the unit enters the Bulk Charging Mode until the instant the battery voltage reaches
0.3V below the programmed Absorption Voltage, then registers this time as Bulk Charge Time
To and computes the Absorption Time T1 as 10 times the Bulk Charge Time To in the internal
“T1 Timer” i.e. T1 = To x 10. The “T1 Timer” is used to determine the time the charging will
take place in the next Absorption Stage.
5.6.1.1 Automatic Adjustments of Internal AC Charger Current when External
Charger is also Charging in Parallel
Please note that if an external charger is also used to charge the batteries at the same time in
parallel with the internal AC charger of the unit [through input terminals marked EXT.charger (3,4 in Fig 2.1)], the charging current of the internal AC charger will be controlled so that the total
charging current of the external charger and the internal charger is = the programmed "BULK
CURRENT (“Io”).
For example, if the programmed "BULK CURRENT (“Io”) is say 40A and the charging current of
the external charger is 30A, the internal AC charger will output only 10A (Programmed setting
of 40A – external charging current of 30A = 10A). Similarly, if the programmed setting is say
30A and the external charger is 50A, the internal AC charger will NOT provide any charging.
Please refer to Section 5.4 for more details.

5.6.2 Absorption Stage
During the Absorption Stage, the charging voltage is held constant near the Gassing /
Absorption Voltage to ensure that the battery is further charged to the full capacity without
overcharging. The Absorption Stage restores the remaining 25% of the battery’s charge. The
time the charger remains in the Absorption Stage is proportional to the depth of discharge of
the battery. When the battery is more discharged, it will take longer time in the Bulk Charge
Stage to reach the Gassing / Absorption Voltage. As a part of the Adaptive Charging Algorithm,
the “T1 Timer” (explained above) computes the time the charging takes place in this stage.
Absorption Time T1 = Bulk Charge Time To x 10 (To = Time from entering Bulk
Charge Stage till battery voltage rises to 0.3V below Absorption Voltage).
The “T1 Timer” has minimum time of 1 hour and a maximum time of 12 hours.When the T1 Timer runs out, the charger will enter the next Float Stage. Pr
ogrammable range and Default values of Absorption Voltage are shown in Table 6.2.

loat Stage is a maintenance stage in which the output voltage is reduced to a lower level, typically
about 13.5 volts, (27 volts for 24V models) to maintain the battery’s charge without losing electrolyte

5.6.4 Automatic Resetting of Charging Cycle in 3 Stage Charging Prole
The charging cycle will be reset to the Bulk Stage as follows:
If the AC input from the Grid/Generator is disconnected and is reconnected or the battery
-
voltage drops below 12 VDC / 24 VDC (Default). Programmable range for this voltage is 10 to
13V for 12V battery and 20 to 26V for 24V battery (This parameter is called "FLOATING EXIT".
See Table 6.2 and Table 4.4 of Section 4.4 of Owner's Manual for EVO-RC at Appendix A).
- If the charger remains in the Float Mode for 10 days.
5.7 4 STAGE CHARGING IN EQUALIZATION MODE
!
CAUTION!
Equalization Mode should be performed only on vented, ooded (non-sealed or
“wet”) batteries and not on the sealed AGM / Gel Cell batteries and only as often as
recommended by the battery manufacturer.
!
ATTENTION!
La mode d’égalisation devrait être faite sur des batteries ventillées, inondées (batteries non-scellées ou «mouillées»)
et pas sur des batteries scellées (AGM) ou cellulles gelées et, aussi souvent que les recommandations du fabricant.
4 Stage Battery Charging Cycle is used in the Equalization Mode. Equalization Mode is selected
using optional Remote Control EVO-RC [Refer to parameter "CHARGE MODE" at Screen No.12
of Table 4.4 of Owner's Manual at Appendix A. The "CHARGE MODE" is required to be set at

1 = Equalize (4-stage)]. Equalization of the batteries is carried out periodically - normally once
per month for battery under heavy duty service and every two to four months for battery under
light duty service. As equalization is a deliberate overcharge of the battery for a specied time
period, equalizing your ooded / wet cell batteries will reduce sulfation, stir up the electrolyte
to remove stratication, equalize voltages of individual cells and thus, help reach and maintain
the peak capacity of the battery.
Please read about the necessity and details of equalizing batteries under White Paper
titled “Batteries, Chargers and Alternators,” available online at www.samlexamerica.
com (Home > Support > White Papers).
The 4 stages of the cycle will be - Bulk, Absorption, Equalization, and Float. Equalization Mode
is desirable for the proper health of Wet Cell Batteries. "EQUALIZE VOLTAGE" is programmable
through the optional Remote Control Model EVO-RC (see Screen No.3 in Table 4.4 of Owner's
Manual for EVO-RC at Appendix A). Programmable voltage range and default values are shown
in Table 6.2.
Equalization current and Equalization time are computed automatically. (See Section 5.8)
F
ig 5.2 shows the voltage and current curves during the 4 stages of charging in this mode.
When Equalization is selected (requires optional Remote Control Model EVO-RC (see Appendix
A), the charger will rst execute Bulk Stage followed by Absorption Stage. On completion of
Absorption Stage, the charger will execute Equalization Stage. After completion of Equalization
Stage, the charger will enter Float Stage. The stage transitions will thus be: Bulk Stage
(Constant Current) Absorption stage (Constant Voltage) Equalization Stage (Constant
Voltage) Float Stage (Constant Voltage).
As part of the Adaptive Charging Algorithm, the charging prole in the Equalization Stage
is based on the time
To which is the time the charger remains in the initial Bulk Stage. The
charger will remain in the initial Bulk Stage for a longer duration when the battery is deeply
discharged and for a shorter duration if the battery has a shallow discharge.

5.8 DETAILS OF EQUALIZTION MODE CHARGING CYCLE (Fig 5.2)
During the Bulk Stage, the charger will charge at the programmed "BULK CURRENT"
(“Io“) (see programmable range at Table 6.2. Default value is 40A). "BULK CURRENT"
(“Io”) is normally limited to 10%-20% of the Ah capacity of the battery (20Hr Rate).
Higher current may be used if permitted by the battery manufacturer in Equalization
Mode. The Bulk Stage is displayed as "E-CC" in the Charging Mode screens of the
optional Remote Control EVO-RC (Please refer to Section 3.6.1 of Owner's Manual
for EVO-RC at Appendix A).
A Software Timer is used to measure the time taken from the time the unit transfers to the
Utility / Generator Mode / enters Bulk Stage until the battery charger reaches 0.3V below
the Absorption Voltage, then registered this time as time To. The following times are computed based on the time To:
Absorption T
Equalization Time T2 is then computed based on the following logic:
T2 = T1’ + 1 hr = 0.5 T
T2 = T1’ + 2 hrs = 0.5 To + 2 hrs ; if 2 < T1’ < 4 hrs
T2 = T1’ + 4 hrs = 0.5 To + 4 hrs ; if T1’ > 4 hrs
When the battery r
range and defaults at Table 6.2), it transitions to the Absorption Stage and remains in this
stage for the computed time T1’. This stage is displayed as "E-CVA" in the Charging
Mode screens in Remote Control EVO-RC (Please refer to Section 3.6.1 of Owner's
Manual for EVO-RC at Appendix A).

Section 3.6.1 of Owner's Manual for EVO-RC at Appendix A).
Automatic Resetting of Charging Cycle
The charging cycle will be reset to the Bulk Stage of 3 Stage Charging Prole as follows:
- If the AC is reconnected or the battery voltage drops below 12 VDC / 24 VDC (Default).
Programmable range for this voltage is 10 to 13V for 12V battery and 20 to 26V for 24V battery.
(This parameter is called "FLOATING EXIT". Please see Table 6.2 and Table 4.4 of Section 4.4 of

5.9 SWITCHING ON AND SWITCHING OFF OF EQUALIZATION MODE
(4 STAGE CHARGING)
The unit comes preset for charging in Normal "CHARGE MODE" (3 Stage Charging Prole).
"EQUALIZE MODE" (4 Stage Charging Prole) is required to be selected manually as follows:
Using ON/OFF Push Button on the Front Panel: When the unit is in Charging Mode (qualied
Grid / Generator Input is available), the Green LED “Status” will be ashing once per second. Press
the ON/OFF Button for 1 second. The ongoing Normal "CHARGE MODE" will be terminated and
Equalize "CHARGE MODE" will be initiated. The Green “Status” LED will start ashing 2 times
per sec to show that Equalize "CHARGE MODE" is active. The unit will complete Equalization
Cycle and terminate in Float Stage. At the same time, the "CHARGE MODE" Setting will again
reset to Normal Mode and the Green LED “Status” will return to 1 ash per second. To terminate
Equalization Mode prematurely before its completion, press the ON/OFF Push Button for 1 second.
If the unit was in Inverting Mode (Green LED “Status” steady) and the Mode is set to
Equalization as above by pressing the ON/OFF Push Button for 1 second, the unit will
undergo Equalization Mode whenever qualied AC input is available from Grid / Generator
and the unit enters Charging Mode. To terminate Equalization Mode prematurely before its
