4-Stage charging(Boost, ABS, Equalization, Float), and equipped with industrial-grade STM 8 microprocessor to prolong your battery life cycle. Dual USB can give your electronic product max 5V 2.5A. This solar charge controller backlight display PV/Battery/Load charge and discharge parameter. like the fourth picture, adjustable Floating voltage/LVD/LVR/Timer according to needs with power-off-memory function. This solar charge controller is fit for Lead-acid batteries(OPEN, AGM, GEL) with multiple load timers. Load should be DC. For protecting the lifespan of your battery, once the voltage of the battery drop below 8V, the solar controller will turn off automatically. Eight PWM charge controller Protection:Power off memory /Dual MOSFET Reverse current /over heat /Under-voltage discharge /short-circuit /open-circuit / over-load /over-charging protection.more safe for home, industrial,commercial etc.

Display/Setting The battery positive and negative pole according to the icon access controller, the control er will automatically detect the battery voltage, the load positive and according to the icon access controller, pay attention, not to negative pole answer, the solar panel according to the icon access controller. please strictly follow the above order to access, otherwise, it may damage the controller or other components; the disassembly sequence is contrary to the wiring order. 12V system with 17.5V solar panels,24V system with 36V solar panels.

connection diagram

1.Connect order : 1. Battery --->2.Solar panels ---> 3.DC load.

2, Disconnect order : 1. DC load --->2. Solar panels ---> 3. Battery

3. The battery cable should be as short as possible to minimize loss.

4. When installation for the first time, set the battery type according to the type of battery and make sure that the battery has enough voltage so that the controller can recognize the correct battery type.

5. The charge regulator is only suitable for regulating solar modules. Never connect another charging source to the charge regulator.

6. the light control function is controlled by the solar panel, the use of light control

the function must access the solar panel, otherwise, the light had no effect
