WIFI/GPRS/ETHERNET for optionalJN-K DC 12V 24V 48V automatic recognition smart pwm solar charge controller 10A 20A 30A
The controller is suitable for the automatic control of charging and discharging process in the off-grid solar system (independent system). The battery charging and discharging process of the controller is optimized, which can prolong the life of the battery and improve the performance of the system. The comprehensive function of self testing and electronic protection function can avoid the installation errors and system failures which can cause the controller damage.
