SmartSolar MPPT 150/35 & 150/45 A solar charger collects energy from your solar panels and stores it in your batteries. SmartSolar uses the latest, fastest technology and maximises this energy harvest by driving it intelligently to achieve a full charge in the shortest possible time. SmartSolar maintains battery health and extends their life. The SmartSolar charge controller even recharges a heavily discharged battery. It can be operated with a battery voltage of up to 0 volts, provided the cells are not permanently sulphated or otherwise damaged.

MPPT: Ultra Fast Maximum Power Point Tracking By constantly monitoring the voltage and current output of your solar panels (PV), MPPT technology ensures that every drop of available energy is flushed from your panels and harvested for storage. The benefit is most evident when the sky is partly cloudy and the light intensity is constantly changing.
