JN-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.
