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
