Advantages of MPPT:

The "Maximum Power Point Tracking" (MPPT) is a system that allows more energy from PV modules or other equipment, permanently adjusting their operating conditions.

MPPT principle:

The maximum power point is mainly affected by the ambient temperature and the intensity of sunlight. If the intensity of sunlight is constant, the maximum output power decreases with increasing temperature. If the temperature is constant, when solar radiation increases, the voltage circuit basically remains unchanged. This system allows substantially increase in the maximum output power.

The intelligent charge controller WS-MPPT can regulate the working voltage of the PV modules, making them always working at the peak of VA curve. Compared with a common charge controller, this MPPT controller can increase the efficiency of photovoltaic modules in about 10% to 30%.
