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