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)
