The controller is for off-grid solar system and control the charging and discharging of
the battery. Main function is protecting battery. The intelligent charging process has
been optimized for long battery life and improved system performance.
Major Functions
The features are listed below:
•Automatic Identification System Voltage, 12V 24V auto recognition
•Humanized LCD displaying and double button operation of man-machine
interface.
•Completed technical data for setup and modify.
•High efficiency intelligent PWM 3stage charging The load control mode can be
selected, the timer.
•function can be reset for street light at night.
•Reliable over voltage protection . short circuit protection . over load protection .
overcharge protection. over-discharge protection.
•Accurate temperature compensation, correcting the charging and discharging
voltage automatically, improving the battery lifetime.
•Roundly reverse connected protection.
•Solar Panels, Battery, Solar Charge Controller positive poles are all connected
together, adopting negative MOSFET in series control circuit.
Important Safety Information
•BH It is better to install the controller in the room. If installed the controller
outside, please keep the environment dry, avoid direct sunlight.
•The controller will be hot in process of working, please keep the environment
ventilation, away from flammable.
•BH The open circuit voltage of solar panel is too high, (especially 24V system),
please take care.
•HB The battery has acidic electrolysis, please put on goggles during installation. If
you accidentally exposed to the electrolysis, please rinse with water.
•BH The battery has huge power, prohibit any conductor short circuit the positive
and negative pole 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 controller.)

The suggestion of using
•The 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.
•Recommend system current density of cables less than 3A/mm2.
•Try to use multi strand copper wire in order to connecting with the terminal
firmly. Loose power connection and for corroded wires may result in resistive
connections that melt wire insulation, burn surrounding materials, or even cause
fire.
•The battery should be full charged each month. Or the battery will be destroyed.
The feature of LCD graphic symbol
1. The default night display of controller: When the solar panel input voltage have been
detected by controller less than sensor identification point voltage, this graphic symbol
will be light.
2. The default daytime display of controller: When the solar panel input voltage have
been detected by controller more than sensor identification point voltage, this graphic
symbol will be light.
3. The indicator of PV array parameter: When the solar panels data was displaying, this
graphic symbol will be light. For example the voltage of solar panel.

4. The indicator of battery parameter: When the battery parameter was displaying, this
graphic symbol will be light. For example the voltage of battery, temperature of battery.
5. The indicator of load parameter: When the load parameter was displaying, this
graphic symbol will be light.
6. System Voltage: When the LCD shows different system voltage, the controller will
adjust the technical data automatically.
7. Numerical Display Area
8. Timer Setting Function
9. Switch Graphic Symbol.
10. Unit Symbol Value
11. Warning: When there is fault, this graphic symbol will be light.
12. The indicator of Load status: Load on, Load off.
13. The indicator of Output power: When the load terminal have output, this graphic
symbol will be light.
14. The indicator of capacity of battery: When the battery was in different capacity, the
strip-type will show.
15. The indicator of charge status: When the controller is charging, the symbol will be
light, float charge will be flash, no charging no display.
Installation Instructions
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 155.8mm*63mm, diameter of the hole is 5mm.

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, or cause system
voltage recognition fault.
•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 indicate,
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.)
•If the battery reverse connection, the output of controller also same with battery
polarity, please do not connect any load with controller at that time, or the load
and controller will be destroyed.
•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.
•The voltage of solar panel is very high under sunshine, high voltage
can cause injury or destroy controller. 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 load
will be destroy bulb.
Operation and Indication
Main Interface
The controller will have 1s initialization interface after electrified, then go into main
interface.
If no operation at main interface inner 20s, the main interface will be auto exchange
during voltage of battery, voltage of solar panel, temperature of environment each
interface keep 3s. Long press “→”more than 5s at main interface, it will speed auto
exchange. Loose button will stop speed.

a) Float Voltage Set up
This parameter is High Voltage Disconnection (HVD) voltage. (Boost state voltage will be
increase 0.6V base on HVD) The controller will be started PWM function at this point (HVD),
limited voltage rising.
Press “←" join in float voltage menu. Long press “←"button≥5S, the parameter on the
interface will be flash, here is set up state. Loose the button, press “←” button again could
operate plus data, press ”→” button could operate minus data. After finish the needed
technical data, long press “←" button again ≥5S , the parameter save and come out set up
state. If 20s no any operation, automatically back to main interface.
b) Low Voltage Reconnection Voltage (LVR)
When the voltage of battery is low the control will stop offer power to the load. If the
controller needs reconnected the output, the voltage voltage of battery must be higher than
LVD voltage or press “→” button force to release. The procedure is same with (a).
