A solar charger is powered by solar modules and stores this energy in batteries. Using the fastest technology, the SmartSolar maximizes this energy generation and directs it intelligently to charge the batteries as quickly as possible. The SmartSolar maintains the functionality of the battery, thereby extending its lifespan. The SmartSolar charge controller can even recharge a deeply discharged battery. It can operate with a battery voltage of just 0 volts, provided the cells are not permanently sulfated or otherwise damaged.
