JN-K Series 10a 20a 30a Solar Controller
Solar panels may make power at very high voltage and current. If all that is fed directly to the battery then it may get overcharged or blast (in extreme cases).A solar charge controller prevents this from happening. It is is placed in between the solar panels and the battery bank to regulate the charging current and voltage of the batteries through solar. It also prevents the reverse flow of current from batteries to the solar panels during night-time.Basically, without a charge controller it is not possible to safely use solar energy for charging batteries.
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.
