MPPT Technology Introduction
MPPT means Maximum Power Point Tracking, it is more advanced solar charging mode. In view of
nonlinearity feature of solar panels, there is a Maximum Power output Point(PMax）, and this point under
changing light intensity and temperature. Using traditional PWM solar charge controller, the voltage of
solar panel will be clamped by battery, the voltage can not be maintained at PMax to charge the battery,
greatly reduce the utilization rate of solar panels. MPPT technology adopt high efficiency DC-DC power
transform technology, with advanced algorithm to track the MPP of solar panels in actual time to
obtain Max power from solar panel for charging battery. Compare with PWM controller, MPPT solar
charge controller could increase the energy utilization rate 15%-30%.
The solar panel used for 12 system Vpp is 17V, due to the constant current characteristic of solar
panels, when the 12V battery is charged by solar panel, the voltage of solar panel will be clamped by
battery. If the max charging current is 10A at this time, then the input power to the battery= 10A x 12V
=120W, not yet completely play the maximum utilization rate of solar panels. MPPT controller could
adjust the voltage and current of solar panels to reach Max output power, the input power to the
battery= 9A x 17V x 0.98(circuit exchange efficiency)=150W, it can be seen that the MPPT controller
could significantly improve the charging efficiency.

The MPPT point under changing light intensity and temperature of environment, The MPPT
controller could adjust the MPP timely according to different conditions.
In application the solar panel have burnt cells or shadow effect, may cause multi MPP appearance,
but only one of these point is actual MPP as shown below.
MPPT double peaks drawing
When multi MPP points appear, if the program is not perfect, it will cause the solar system to work in
the non actual MPP points, waste most of power from solar panel, seriously affect the normal operation
of solar system. Our company’s MPPT controller could accurately track the actual MPP point in the
double peaks or multi peaks state, improve the utilization of solar array and avoid the waste of
resources.
Important Safety Information
①This controller is base on solar panel feature researching, if use other power supply instead of solar panel, the
controller may cause fault.
②It is better to install controller in the room, if install the controller outside, please keep the environment dry, avoid
direct sunlight and waterproof well.
③The controller will be hot in process of working, please keep the environment ventilation, away from flammable.
④The Voc of solar panels is high (especially 24V/48V system, please take care.
⑤The battery had acidic electrolysis, please put on goggles during installation. If you
accidentally exposed to electrolysis, please rinse with water.
⑥The battery has huge power, forbid any conductor short circuit the positive and negative poles of battery. Suggest
to adding a fuse between battery and controller. (Slow motion type, the action current of the fuse should be 1.5
times rated current of the controller)
⑦Please install the controller in a place where children can not touch.
The suggest of using
①The controller could detect the temperature of environment to adjust the voltage of
charging, so that the controller should be closed to battery as near as possible.
②Recommend system current density of cables less than 3A/mm2, Unreasonable cable selection will increase the
system consumption, even burning.
③Try to use multi strand copper wire in order to connecting with the terminal firmly. Loose power connection
and/or corroded wires may result in resistive connections that melt wire insulation, burn surrounding materials
or even cause fire.
④Please keep the battery full charged (one time each month at least), or the battery will be destroyed.
⑤This product have limited solar panel input power function, in theory, no matter how
much power of solar panel input, the controller will limited the input power under rated
power, but must pay attention to the following two points:
The short circuit of solar panel less than rated current of controller.
The Open Circuit Voltage of solar panel increased with decreasing temperature, please ensure in any case, the
Open Circuit Voltage of solar panel array will not exceed 100V, otherwise it will trigger protection or
damage to the controller.
Installation of Instruction
Controller Fixed
1) The controller should be installed well-ventilated place, avoid direct sunlight, high temperature and do not
install in location where water can enter the controller.
2) Please select correct screw to fix the controller on the wall or other platform. Screw M4 or M5, Screw cap
diameter less than 10mm.
3) Please reserve enough space between the wall and controller, to allow for cooling and cable connection.
4) The mounting holes distance is 189mm*85mm，diameter of hole is 5mm。
5) Aluminum fins for natural cooling, we strong suggest hanging installation, this is better for air flow cooling effect.
Controller Connection
All terminals are in tight status after factory, in order to well connected, please loose all terminals at first.
The following order of connection please do not free change, the controller have battery voltage auto selection
function, or cause system voltage recognition fault.
Before connection, please confirm the voltage of system fit for our controller, the open circuit of solar panel and
maximum power at the using range of controller.

In order to avoid fault installation, please refer to below procedure
1) As figure, first connected the battery to controller correct poles. In order to avoid short circuit, please screw the

cable of battery to the controller in advance, then connected to battery poles secondly. If your connection is
correct, the LCD displaying will show battery voltage and other technical data. If LCD no displaying, please check
the fault. The length of cable between battery and controller as shorter as possible. Suggest to 30CM -100CM.
If short circuit happened on the terminals of controller, it will be result in fire or explode. Please be careful.
(We strongly suggest to connecting a fuse at the battery side 1.5time of rated current of controller.)
2) As figure, connected solar panels with controller correctly, if the connection is successful and sunshine is full, the
LCD will show solar panel and an arrow from solar panel to battery will be light, we have below suggestions about
solar panels connection.
Risk of electric shock, please pay attention to protection
The max input voltage from solar panel could reach 100v, please try to use series connection in order to
simplified cables.
In series connection could get down the current of solar panel, reduce sectional area of cable and voltage drop.
For example: 17V 120Wx2 solar panels charge 12V battery, if we use PWM controller, we have to in parallel
connection, the solar panel array voltage is 17V, current is 14A, current density is 3A/mm2. So we need
sectional area 5 mm2. If we in series connection solar panels array voltage is 34V, current is 7A, At this time
we need sectional area of cable 2.5 mm2, half conductor area reduced than parallel connection.
3) As figure, connected loads with controller correctly. In order to avoiding injury from load voltage, please close to
the output of controller with button at first, then connected the load on the controller. The controller do not
offer reverse connection protection for load, so please take care, reverse connection for output will be destroy
loads.
Attention: If users want to connect inverter or inrush starting current loads, please connected
them with battery directly, do not connected them with controller, or the controller load can not
be start or destroy.
4) Insert type external temperature sensor: external temperature sensor used for temperature compensation, please
closed to battery as nearer as possible, if the temperature sensor do not plug in, the controller will default 25℃.
5) RS485 communication interface: Monitored by professional wire and host computer. (optional）
6) USB output：USB could offer 5V，Max 1000mA for mobile, laptop, MP3 and so on. (40A not available USB output
at the moment）
Warning: Please do not connect USB loads to anywhere, the USB output negative poles is in series with Load
negative poles.
About ground connection of solar system
Please noted, this solar charge controller designed by all positive connection, all
components inside the controller are positive combined together. If your solar system needs
ground connection, please let positive ground connection.
Warning: For some force to ground connected system, such as solar communication system, portable solar
system, they are negative ground connected, at this time please do not positive connected, or can cause short
circuit.
Battery Charging Process
This controller has 3stages charging mode, bulk, boost, float, through fast high efficiency safety charging mode,
effectively prolong the service life of the battery.
①Bulk charging：Fast charging stage, the voltage of battery is not reach to full charged set point. (Float point or
Boost point), the controller will be work at MPPT mode. In process of Maximum Power of solar panel charging.
②Boost charging：Each time the battery voltage less than 12.6V, the controller will auto boost charging one time.
When the boost voltage reach to set point, the controller will join into constant voltage charging mode instead
of MPPT mode, and gradually reduce the charging current, the boost charging continued 2H then go to float
charging mode. (Due to the load capacity and generated changing, the controller can't keep constant voltage
charging, the constant voltage charging time will be accumulated, accumulate 2hours cancel boost charging
mode.
③Float charging：After join into float mode, the controller will get down charging current, to carry out weak
charging to keep the battery at float voltage. (If the battery isn’t less than 12.6V, the controller will not start
boost charging mode, only keep floating)
