The Technology of our Solar Charge Controllers is known as the Maximum Power Point Tracking (MPPT). It is the best and most recent type of Solar Charge Controllers that is available anywhere in the World. MPPT controllers have a lot of advantages over the regular or conventional Technology of Solar Charge Controllers known as the Pulse Width Modulation (PWM). Because Solar panels can sometimes deliver far more voltage than is required to charge the Batteries, the MPPT Controllers ensure that the excess voltage from the Solar Panels is converted into amperage to charge the Batteries. By converting the excess voltage into amperage, the power loss in the cable, if any, is reduced significantly; the charging voltage of the Solar System is kept at an optimum level; while the time required to fully charge the Batteries is reduced, that is, the Batteries get charged faster. Also, at night, when the Solar Panels do not generate electricity, our MPPT Solar Charge Controllers can detect when no energy is coming from the Solar Panels and open the circuit, disconnecting the Solar Panels from the Batteries and stopping reverse current flow. The foregoing allows the Solar Power System to operate optimally at all time, even during adverse weather conditions. Thus, if you want the best performance for your Solar System, then, you surely need our MPPT Solar Charge Controller.
