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 :
