Mppt Solar Charge Controller

Foto Focus offers a Maximum Power Point Tracking (MPPT) Solar Charge Controller. This enables the solar panel to always work at the maximum power point of the V-A curve, and increases efficiency of solar panel modules by 10% to 30%. MPPT principle: the maximum power point is mainly affected by the ambient temperature and the intensity of sunshine. The intensity of sunshine being constant, the maximum power decreases with the rise of temperature. The temperature being constant, when the sunshine intensifies, the voltage of PV module keeps unchanged but the current increase substantially thus the maximum output power increase. This MPPT solar charge controller can intelligently regulate the working voltage of solar panels, letting the solar panels always work at maximum power point of V-A curve. Compared with ordinary solar controller, this MPPT controller can increase the efficiency of PV modules by about 30%. However, due to many factors, such as the different in solar panel making, the change of sun illuminance, temperature, etc, the actual available increase rate is 10-30%
