2 Introduction
2.1 General Information
SD Series Pure Sine Wave Inverter is a combination of an inverter, battery charger and AC
auto-transfer switch into one complete system with a peak conversion efficiency of 85%.
It is packed with unique features and it is one of the most advanced inverter/chargers in the market
today.
It features power factor corrected, sophisticated multi-stage charging and pure sine wave output with
unprecedentedly high surge capability to meet demanding power needs of inductive loads without
endangering the equipment.
When the utility AC power cuts off or falls out of acceptable range, the tr ansfer relay is de-energized
and the load is automatically tr ansferred to the Inverter output. Once the qualified AC utility is
restored, the relay is energized and the load is automatically reconnected to AC utility
The SD Series Inverter is equipped with a powerful charger of up to 110Amps (for 4KW one).
The overload capacity is 300% of continuous output for up to 20 seconds to reliably support tools

3 Electrical Performances
3.1 Invert
Topology
The SD inverter/charger is built according to the following topology.
Invert: Full Bridge Topology.
Charge: Isolate Boost Topology
Because of high efficiency MOSFETs and 16bit, 4.9MHZ microprocessor and heavy transformers, it
outputs PURE SINE WAVE AC with an average THD of 7% (min 3%, max 10%) depending of load
connected and battery voltage.
The peak efficiency of SD Series is 85%.
Overload Capacit y
The SD Series inverters have different overload capacities, making it ideal to handle demanding
loads.
For 110%<Load<125% (±10%), no audible alarm in 14 minutes, beeps 0.5s every 1s in the 15th
minute, and Fau lt(Turn off) after the 15th minute
For 125%<Load<150% (±10%), beeps 0.5s every 1s and Fault (Turn off) after the 1 minute
For 300%Load>150% (±10%), beeps 0.5s every 1s and Fault (Turn off) after 20s.
Caution:
- 5 -
Ultimate Power www.upinverters.com
After the inverter is switched on, it takes a finite time for it to self-diagnoses and get ready to deliver
full power. Hence, always switch on the load(s) after a few seconds of switching on the inverter.
Av oid switching on the inverter with the load already switched on. This may prematurely trigger the
overload protection. When a load is switched on, it may require initial higher power surge to start.
Hence, if multiple loads are being powered, they should be switched on one by one so that the
inverter is not overloaded by the higher s tarting surge if all the loads are switched on at once.
3.2 AC Charger
SD Series is equipped with an active PFC (Power Factor Corrected) multistage battery charger. The
PFC feature is used to control the amount of power used to charge the batteries in order to obtain a
power factor as close as possible to 1. Unlike other inverters whose max char ging current decreases
according to the input AC voltage, SD Series charger is able to output max current as long as input
AC voltage is in the range of 95-127VAC, and AC freq is in the range of 58-64Hz. The SD Series
inverter possesses a strong charging current of 110Amp (for 4KW 12Vdc model), and the max
charge current can be adjusted from 0%-100% v ia a liner switch to the right of the battery type
selector. This will be helpful if you are using our powerful charger on a small capacity battery bank.
Choosing “0” in the battery t ype selector will disable charging function.

The de-sulphation cycle on switch position 8 is marked in red because this is a very dangerous
setting if you do not know what you are
doing. Before ever attempting to use this
cycle you must clearly understand wh at it
does and when and how you would use
it.
What causes sulphation? This can occur
with infrequent use of the batteries, or if
the batteries have been left discharged so
low that they will not accept a charge.
This cycle is a very high voltage charge

Charging depleted batteries
The SD Series inverter allows start up and through power with depleted batteries.
For 12VDC model, after the battery voltage goes below 10V, if the switch is still(and always) kept in
"ON" position, the inverter is always connected with battery, and the battery voltage doesn’t drop
belo w 2V, the inverter will be able to charge the battery once qualified AC inputs.
Before the battery voltage going below 9VDC, the charging can activated when the switch is turned
to “Off”, then to “ON”.
- 7 -
Ultimate Power www.upinverters.com
When the voltage goes below 9VDC, and you accidently turn the switch to OFF or disconnect the
inverter from battery, the inverter will n ot be able to charge the
battery once again, becau se the CPU lose memory during this
process.
Start up without battery function can be customized upon request.
The charging capacity will go to peak in around 3 seconds; this may
probably cause a generator to drop frequency, making inverter
transfer to battery mode.

It is suggested to gradually put charging load on the generator by switching the char ging switch from
min to max, together with the 15s switch delay, our inverter gives the generator enough time to spin
up.
3.3 AC Transfer
While in the Standby Mode, the AC input is continually monitored. Whenever AC power falls below
the VAC Trip voltage (90 VAC, default setting), the inverter automatically transfers back to the
Invert Mode with minimum interruption to your appliances - as long as the inverter is turned on. The
transfer from Standby mode to Inverter mode occurs in approximately 10 milliseconds. And it is the
same time from Inverter mode to Standby mode.
Though it is not designed as a computer UPS system, this transfer time is usually fast enough to hold
them up.
There is a 15-second delay from the time the inverter senses that continuously qualif ied AC is
present at the input terminals to when the transfer is made. This delay is built in to provide time for a
generator to spin-up to a stable voltage and avoid relay chattering. The inverter will not transfer to
generator until it has locked onto the generator’s output. This delay is also d esigned to avoid frequent
switch when input utility is unstable.
3.4 Auto Frequency Adjust
The inverter is designed with Auto Frequency adjust function.
The factory default configuration is 60Hz for the SD series inverter
While the output freq can be easily changed once a qualified freq is applied to the inverter.
If you want to get 60Hz from a 50Hz inverter, just input 60Hz power, and the inverter will
auto matically adjust the output freq to 60Hz and vice versa.
NOTE: The inverter will output factory set freq after it restarts.
3.5 Power Switch
- 8 -
Ultimate Power www.upinverters.com
There are three different working statuses for SD inverter: “On”, “Off” and “Ready”.
When power switch is in “Off” position, the inverter is powered off.
When power switch is turned to “ON”, the inverter is powered on.
When power switch is turned to “Ready”, the inverter will charge the battery when there is qualified
AC input. If there is no AC power input, the inverter waits for 12Vdc remote start signal to go into
inverter mode. Once the 12Vdc remote start is activated, the inverter powers on. When th e 12Vdc
remote start is de-activated, the inverter goes to “Ready” mode again.

When in the search sense mode, the green power LED will blink and the inverter will make a ticking
sound. At full output voltage, the green power LED will light steadily and the inverter will make a
steady humming sound. When the inverter is used as an “uninterruptible” power supply the search
sense mode function should be defeated.
3.6 Protections
The SD Series inverter is equipped with extensive protections against various harsh situ ations/faults.
These protections include:
AC Input over voltage protection/AC Input low voltage protection
Low battery alarm/High batter y alarm
Over temperature protection/Over load protection
Short Circuit protection (1s after f ault)
Back feeding protection
When Over temperature /Over load occur, after the fault is cleared, the master switch has to be reset
to restart the inverter. The inverter will go to over temp protection when the heat sinks temp. ≥105ºC
(221℉), and will go to Fault (shutdown Output) after 30 seconds. The switch h as to be reset to
activate the inverter. The SD Series Inverter is with back feeding protection which avoids presenting
an AC voltage on the AC input terminal in Invert mode. After the reason for fault is cleared, the
inverter has to be reset to start working.
3.7 Remote Control
Apart from the switch panel on the front of the inverter, an
extra switch panel connected to the RJ45 port at the DC side
- 9 -
Ultimate Power www.upinverters.com
of the inverter through a standard telephone cable can also control the operation of the inverter. If an
extra switch panel is connected to the inverter via “remote control port”, together with the panel on
the inverter case, the two panels will be connected and operated in parallel.
The Inverter can also be switch on/off through the “RMT SW” pin in the right of AC terminal.
They inverter will be powered on once a +12Vdc (acceptable range 10-16Vdc) source is connected
to the PIN, and powered off when the +12Vdc source is disconnected ( if the switch panel is in
“Ready” position).
The 12Vdc remote start is with the same priority as “ON”.
Only when both panels and 12Vdc remote control are turned to “Unit Off” positio n, will the inverter
be powered off.
WARNING
Never cut the telephone cable when the cable is attached to inverter and battery is connected to the
inverter. Even the inverter is turned off, this will damage the remote PCB inside if the cable is short
circuited during cutting.
12Vdc Remote Control Wiring Diagram
WARNING
The rated current of remote control terminal is
0.5Amp, over current may damage the inverter.
Thus it must be protected with an appropriate DC
fuse; the suggested value is 1 Amp.
WARNING
Connecting this wire to chassis ground will cause
damage not covered under warranty!
The remote switch should be single pole, single throw with at least a 1 Amp rating. The wire used
should be at least 18ga

3.11 DIP SWITCHES & BTS
On the DC end of inverter, there are 3 DIP switches wh ich enable users to customize the
performance of the device to suit the specific configuration.
Switch NO Switch Function Position: 0 Position: 1
SW1 Low Battery Trip Volt 10.0VDC 10.5VDC
*2 for 24VDC, *4 for 48VDC
SW2(230V) AC Input Range 184-253VAC 154-264VAC(40Hz+)

SW3 Power Saver & Unit Off
Charging
Low Battery Trip Volt:
Deep discharge of the lead acid battery leads to high losses in capacity and early aging. In different
applications, different low voltage disconnection level is preferred. For example, for solar application,
user intended to have less DOD to prolong the battery cycle life. While for mobile app lication, users
intend to have more DOD to reduce b attery capacity and on board weight.
Unit Off charging Power Saver
- 12 -
Ultimate Power www.upinverters.com
For 12VDC model, the Low Battery Trip Volt is set at 10.0VDC by default. It can be customized to
10.5VDC using SW1, this is to prevent batteries from over-discharging while there is only a small
load applied on the inverter.
*2 for 24VDC, *4 for 48VDC
AC Input Range:
There are different acceptable AC input ranges for different kinds of loads.
For some relatively sensitive electronic devices, a narrow input range of 184-253VAC (100- 135V for
120VAC model) is required to protect them.
While for some resistive loads which work in a wide voltage range, the input AC range can be
customized to 154-253VAC (90-135V for 120VAC model), this helps to power loads with the most
AC input power without frequent switches to the battery bank.
In order to make the inverter accept dirty power from a generator, when the SW2 is switched to
position “1”, th e inverter will bypass an AC input with a higher voltage(164-264Vac for 230Vac
model) and wider frequency (40Hz plus for 50Hz/60Hz). Accordingly, the AC charger will also work
in a higher voltage(174-254Vac for 230Vac model) wider freq range (43Hz plus for 50Hz/60Hz).
This will avoid frequent switches between battery and generator. But some sensitive loads will suffer
from the low quality power.
The pros and cons should be clearly realized.
Power Saver & Unit Off Charging:
Under the Battery Priority Mode (SW5 in position “1”), the inverter can be switched between two
modes: Power Saver Mode (SW3 in position “1”) and Unit Off Charging Mode (SW3 in position
“0”). The power Switch should be in “Power saver on” position all the time for using these functions.
In Power Saver Mode, the inverter is initially in standby mode and sends a pulse to d etect the
presence of a load every 3 seconds. Each pulse lasts for 250ms. The inverter will remain in standby
mode until a lo ad has been detected. Then it will wake up from standby mode and start to invert
electricity from the battery bank to supply the load. As this function is under Battery Priority, the
inverter will always prefer to invert electricity from battery first even there is a qualified AC input
present. Only when the battery voltage is lower than the low voltage alarm point, will the inverter
switch to AC input power to charge the battery and supply the load at the same time.
This Power Sav er Mode can be changed to Unit Off Charging mode via SW3 by switching it to “0”
position. (SW5 still in “1”)
In Unit Off Charging mode, the inverter will stay in standby mode without sensing loads. It won’t
output any power even if a load is turned on or a qualified AC input is present. The inverter will not
perform any function and only stay idle in th is mode, unless the battery voltage is low. Then it will
start charging the battery. This feature is ideally suitable for applications where energy conservation
is required. Charging will only be activated when required.
Applying the proper charge voltage is critical for achieving optimum battery performance and
longevity. The ideal charge voltage required by batteries changes with battery temperature.
The battery temperature sensor allows the charge controller to continuously adjust charge voltage
based on actual battery temperature.
Temperature compensation of charge voltage assures that the battery receives the proper charge

voltage as battery temperature varies.
The entire line are equipped with Battery Temperature Sensing for increased charging precision.
It sends precise information to the charger, which automatically adjusts voltage to help ensure full
battery charge depending on the ambient temperature of your battery installation.
When the battery voltage is over 40℃(104℉), it will reduce the charging voltage by 0.1Vdc with
every degree of temperature rise.
We recommend that you install Battery Temperature Sensors on all banks to protect your b atteries
and to provide op timal charging of each bank.
The battery temperature sensor mounts on the side of a battery or any other location where the
precise temperature of battery can be detected such as battery mounting racks.
The following table describes approximately how much the voltage may vary depending on the
temperature of the batteries.
Inverter Condition Temperature on BTS Charger Operation
Charger Mode BTS ≥ 50℃(122℉) Automatically turns off charger
BTS ≤ 40℃(104℉) Automatically turns on charger
Inverter Mode
40℃(104℉) ≤ BTS ≤ 50℃(122℉)
BTS ≥ 50℃(122℉) Over Temp Fault
Increases the low voltage shut down point
by 0.5Vdc
Important: If the battery temperature is allowed to fall to extremely cold temperatures, the inverter
with a BTS may not be able to properly recharge cold batteries due to maximum voltage limits of the
inverter. Ensure the batteries are protected from extreme temperatures.
For more detailed technical information, please contact us .
3.12 Auto Generator Start
The inverter can start up a generator when battery voltage goes low.
When the inverter goes to low battery alarm, it can send a signal to start a generator, and turn the
generator off after battery charging is finished.
The auto gen start feature will only work with generators wh ich have automatic starting capability.
The generator must have start and stop controls [i.e., an electric starter and electric choke (for
gasoline units)], and the safety sensors to be able to start and stop automatically. There is an
open/close r elay that will short circuit the positive and negative cables from a generator start control.
The input DC voltage can vary, but the max current the relay can carry is 16Amp. The Auto
Generator Start terminal pins are not polarized.

Please find the following minimum wire size. In case of DC cable longer than 1m (3ft.) please
increase the cross section of cable to reduce the loss.
The torque rating range for DC terminal is 12.5NM-205NM (9.25-15.19 pound-foot), and the suggested
torque rating is 17NM (12.6 pound-foot). Over torqueing may cause the bolt to break.
In the event of reverse pola rity the unit could be totally destroyed which is not covered under warranty.
WARNING
The inverter contains capacitors that may produce a spark when first connected to battery. Do not mount
in a confined a battery or gas compartment.
4.3 AC Wiring
We recommend using 10 to 5Awg wire to connect to the ac terminal block.
When in AC mode the AC input p ower will supply both the loads and AC charger, a thicker wire
gauge for AC Input is required.
The wirings are UL458 compliant, please consult a qualified electrician or call our tech support if
you are not sure about how to wire any part of your inverter.

Check all DC /AC connections.
Turn the ge nerator output voltage down.
Install a UPS if possible.
*The reason for the noise from transformer and/or case
When in inverter mode and the transformer and/or case of the inverter sometimes may vibrate and
make noise.
The noise may come from transformer:
Accordin g to the characteristics of our inverter, there is one type of load which will most likely to
cause rattles of transformer, that is a half-wave load, load that uses only a half cycle of the power
(see figure 1). That is a half-wave load, load that uses only a half cycle of the power (see figure 1).
This trends to cause imbalance of magnetic field of transformer, reducing its rated working
frequency from 20 KHz to, say, maybe 15 KHz ( it varies according to different loads). This way, the
freq of noise falls exactly into the range (200Hz - 20 KHz) that human ear can sense.
The most common load of such kind is hair dryer.
Figure 1
The noise won’t do any harm to the inverter or the loads.
