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:

  • Blue l – allows output load to be ready for operation.
  • Red l – battery fault statement is over, over current or short-circuit fault è cut off the output of the load.
  • Blue l – has solar power and is charging and maintaining (Float charge) for the battery, V = const.
  • Yellow – has solar power and is charging the battery (Boot charge), I = Max
  • Red L – Over current indicates charging and stopping charging.
