1.4 Maximum Power Point Tracking Technology
Due to the nonlinear characteristics of solar array, there is a maximum energy
output point (Max Power Point) on its curve. Traditional controllers, with switch
charging technology and PWM charging technology, can‟t charge the battery at
the maximum power point, so can‟t harvest the maximum energy available from
PV array, but the solar charge controller with Maximum Power Point Tracking
(MPPT) Technology can lock on the point to harvest the maximum energy and
deliver it to the battery.
The MPPT algorithm of our company continuously compares and adjusts the
operating points to attempt to locate the maximum power point of the array. The
tracking process is fully automatic and does not need user adjustment.
As the Figure 1-2, the curve is also the characteristic curve of the array, the
MPPT technology will „boost‟ the battery charge current through tracking the MPP.
Assuming 100% conversion efficiency of the solar system, in that way, the
following formula is established:
Normally, the V
is always higher than V

discrepancy between array and battery, the bigger reduction of the conversion
efficiency of the system, thus the controller‟s conversion efficiency is particularly
important in the PV system.
Figure 1-2 is the maximum power point curve, the shaded area is charging range
of traditional solar charge controller (PWM Charging Mode), it can obviously
diagnose that the MPPT mode can improve the usage of the solar energy
resource. According to our test, the MPPT controller can raise 20%-30%
efficiency compared to the PWM controller. (Value may be fluctuant due to the
influence of the ambient circumstance and energy loss.)

Figure 1-2 Maximum Power Point Curve
In actual application, as shading from cloud, tree and snow, the panel maybe
appear Multi-MPP, but in actually there is only one real Maximum Power Point. As
the below Figure 1-3 shows:
Figure 1-3 Mutil-MPP Curve

Figure 1-4 Battery changing stage Curve
If the program works improperly after appearing Multi-MPP, the system will not
work on the real max power point, which may waste most solar energy resources
and seriously affect the normal operation of the system. The typical MPPT
algorithm, designed by our company, can track the real MPP quickly and
accurately, improve the utilization rate of the array and avoid the waste of
resources.
1.5 Battery Charging Stage
The controller has a 3 stages battery charging algorithm (Bulk Charging, Constant
Charging and Float Charging) for rapid, efficient, and safe battery charging.
A) Bulk Charging
In this stage, the battery voltage has not yet reached constant voltage (Equalize or
Boost Voltage), the controller operates in constant current mode, delivering its
maximum current to the batteries (MPPT Charging).
B) Constant Charging
When the battery voltage reaches the constant voltage setpoint, the controller will
start to operate in constant charging mode, this process is no longer MPPT
charging, and in the meantime the charging current will drop gradually, the
process is not the MPPT charging. The Constant Charging has 2 stages,
equalize and boost. These two stages are not carried out constantly in a full
charge process to avoid too much gas precipitation or overheating of battery.
5
Boost Charging
The Boost stage maintain 2 hours in default, user can adjust the constant time and
preset value of boost voltage according to demand.
The stage is used to prevent heating and excessive battery gassing.
Equalize Charging
WARNING: Explosive Risk!
Equalizing flooded battery would produce explosive gases, so well
ventilation of battery box is recommended.
CAUTION: Equipment damage!
Equalization may increase battery voltage to the level that
damages sensitive DC loads. Verify that all load allowable input
voltages are 11% greater than the equalizing charging set point
voltage.
CAUTION: Equipment damage!
Over-charging and excessive gas precipitation may damage the
battery plates and activate material shedding on them. Too high
an equalizing charge or for too long may cause damage.
Please carefully review the specific requirements of the battery
used in the system.
AVERTISSEMENT: Risque d‟explosion!
l'égalisation de batteries noyées peut produire des gaz explosifs,
donc il est recommandé de bien ventiler le boitier de la batterie.
ATTENTION: Dégât sur l'équipement!
L'égalisation peut augmenter la tension de la batterie jusqu'à un
niveau nuisible pour les charges CC sensibles. Vérifiez que la
tension d'entrée autorisées de toutes les charges disponibles sont
supérieures à 11% à la tension du point d'installation de
chargement d'égalisation.
ATTENTION: Dégât sur l'équipement!
Un chargement excessif et une précipitation de gaz peut
endommager les plaques de la batterie et la formation de matières
actives dessus. Un chargement trop fort ou une égalisation
prolongée peut causer des dégâts. Inspectez soigneusement les
conditions spécifiques de la batterie utilisée dans le système.
Some types of batteries benefit from equalizing charge on a regular basis, which
is able to stir electrolyte, balance battery voltage and accomplish chemical
reaction. Equalizing charge increases battery voltage, higher than the standard
complement voltage, which gasifies the battery electrolyte.
6
The controller will equalize the battery on 28th each month. The constant
equalization period is 0~180 minutes. If the equalization isn‟t accomplished in
one-time, the equalization recharge time will be accumulated until the set time is
finished. Equalize charge and boost charge are not carried out constantly in a full
charge process to avoid too much gas precipitation or overheating of battery.
NOTE:
1) Due to the influence of ambient circumstance or load working, the battery
voltage can’t be steady in constant voltage, controller will accumulate and
calculate the time of constant voltage working. When the accumulated time
reach to 3 hours, the charging mode will turn to Float Charging.
2) If the controller time is not adjusted, the controller will equalize charge
battery once every month following the inner time.
C) Float Charging
After the Constant voltage stage, the controller will reduce charging current to
Float Voltage setpoint. This stage will have no more chemical reactions and all
the charge current transforms into heat and gas at this time. Then the controller
reduces the voltage to the floating stage, charging with a smaller voltage and
current. It will reduce the temperature of the battery and prevent the gassing and
charging the battery slightly at the same time. The purpose of Float stage is to
offset the power consumption caused by self consumption and small loads in the
whole system, while maintaining full battery storage capacity.
In Float charging stage, loads are able to obtain almost all power from solar panel.
If loads exceed the power, the controller will no longer be able to maintain battery
voltage in Float charging stage. If the battery voltage remains below the Recharge
Voltage, the system will leave Float charging stage and return to Bulk charging
stage.

2 Installation Instructions
2.1 General Installation Notes
Before installation, please read through the entire installation instructions to
get familiar with the installation steps.
Be very careful when installing the batteries, especially flooded lead-acid
battery. Please wear eye protection, and have fresh water available to wash
and clean any contact with battery acid.
Keep the battery away from any metal objects, which may cause short circuit of
the battery.
Explosive battery gases may come out from the battery during charging, so
make sure ventilation condition is good.
Gel, Sealed or Flooded batteries are recommended, other kinds please refer to
the battery manufacturer.
Ventilation is highly recommended if mounted in an enclosure. Never install the
controller in a sealed enclosure with flooded batteries! Battery fumes from
vented batteries will corrode and destroy the controller circuits.
Loose power connections and corroded wires may result in high heat that can
melt wire insulation, burn surrounding materials, or even cause fire. Ensure
tight connections and use cable clamps to secure cables and prevent them from
swaying in mobile applications.
Battery connection may be wired to one battery or a bank of batteries. The
following instructions refer to a singular battery, but it is implied that the battery
connection can be made to either one battery or a group of batteries in a battery
bank.
Multiple same models of controllers can be installed in parallel on the same
battery bank to achieve higher charging current. Each controller must have its
own solar module(s).
Select the system cables according to 5A/mm2 or less current density in
accordance with Article 690 of the National Electrical Code, NFPA 70.
2.2 PV Array Requirements

If the PV array higher than rated power, the charging time at rated power to
battery will be longer, more energy to battery yields.
When the PV array straight polarity, the actual operation of the PV array must
NOT exceed three times of rated charge power；When the PV array reverse
polarity, the actual operation must NOT exceed 1.5 times. For real application
please refer to the table below:
①At 25℃ environment temperature
②At minimum operating environment temperature
2.3 Wire Size
The wiring and installation methods must conform to all national and local

4 Protections, Troubleshooting and Maintenance
4.1 Protection
PV Over Current
The controller will limit charge power in rated charge power. An over-sized PV
array will not operate at maximum power point.
PV Short Circuit
When PV short circuit occurs, the controller will stop charging. Clear it to resume
normal operation.
PV Reverse Polarity
Fully protection against PV reverse polarity, no damage to the controller will
result. Correct the miswire to resume normal operation.
WARNING: Controller will be damaged when the PV array reverse
polarity and the actual operation power of the PV array is 1.5 times
greater than the rated charge power!
Battery Reverse Polarity
Fully protection against battery reverse polarity, no damage to the controller will
result. Correct the miswire to resume normal operation.
Battery Over voltage
When battery voltage reach to the voltage set point of Over Voltage Disconnect,
the controller will stop charging the battery to protect the battery overcharge to
break down.
Battery Over discharge
When battery voltage reach to the voltage set point of Low Voltage Disconnect ,
the controller will stop discharging the battery to protect the battery over
discharged to break down.
Battery Overheating
The controller detect the battery temperature through the external temperature
sensor. If the battery temperature exceeds 65ºC, the controller will automatically
start the overheating protection to stop working and recover below 55 ºC.
Load Overload
If the load current exceeds the maximum load current rating 1.05 times, the
controller will disconnect the load. Overloading must be cleared up through
reducing the load and restarting controller.
Load Short Circuit
Fully protected against load wiring short-circuit. Once the load shorts (more than
quadruple rate current), the load short protection will start automatically. After five
automatic load reconnect attempts, the fault must be cleared by restarting
controller.
Damaged Remote Temperature Sensor
If the temperature sensor is short-circuited or damaged, the controller will be
charging or discharging at the default temperature 25℃ to prevent the battery
damaged from overcharging or over discharged.

Controller Overheating
If the temperature of the controller heat sinks exceeds 85℃, the controller will
automatically start the overheating protection and recover below 75℃.
High Voltage Transients
PV is protected against small high voltage surge. In lightning prone areas,
additional external suppression is recommended.
4.2 Troubleshooting
4.3 Maintenance
The following inspections and maintenance tasks are recommended at least two
times per year for best performance.
Make sure controller firmly installed in a clean and dry ambient.
20
Make sure no block on air-flow around the controller. Clear up any dirt and
fragments on radiator.
Check all the naked wires to make sure insulation is not damaged for serious
solarization, frictional wear, dryness, insects or rats etc. Repair or replace some
wires if necessary.
Tighten all the terminals. Inspect for loose, broken, or burnt wire connections.
Check and confirm that LCD is consistent with required. Pay attention to any
troubleshooting or error indication .Take corrective action if necessary.
Confirm that all the system components are ground connected tightly and
correctly.
Confirm that all the terminals have no corrosion, insulation damaged, high
temperature or burnt/discolored sign, tighten terminal screws to the suggested
torque.
Check for dirt, nesting insects and corrosion. If so, clear up in time.
Check and confirm that lightning arrester is in good condition. Replace a new
one in time to avoid damaging of the controller and even other equipments.
WARNING：Risk of electric shock!
Make sure that all the power is turned off before above operations,
and then follow the corresponding inspections and operations.
