It is a device that performs the function  of regulating the battery’s charge , protects the  battery against overloading  and over-discharge to enhance the life of the  battery,  and helps the solar system to use effectively. fruit and lasting. –  The controller  also shows the charge status of the solar panel on the battery to help users control the loads. – The controller also performs protection against overvoltage (> 13.8V) or low voltage (<10.5V). The controller protection circuit will perform a circuit break when  the controller  confirms that the battery is fully charged or the battery voltage is too low.

 Instruction manual & connection diagram:

– Use within the range of machine specifications.

– Carefully observe the input and output terminals before connecting the pole (+) to the pole (+), the pole (-) against the pole (-).

– Led lights show:

        + Led charging indicator:  

            Lights off: No charging, no connection to  solar panels  or  weak sunlight

            Light on: The indicator is charging

            Flashing light: Full battery indicator or charging indicator

       + Led battery capacity indicator  :

           Green indicator light: Full alert

           Yellow indicator LED: Normal report

           Red indicator light blinks: Low voltage protection for the battery

      + Led download notification:

           Open leds: Download

           Led off: Download                          

           Led light blinks: Off load,  output overload or short circuit
