MPPTprinciple:
The maximum power point is mainly affected by the ambient temperature and the intensity of sunshine. The intensity of sunshine being constant, the maximum output power decreases with the rise of the temperature.
The temperature being constant, when the sunshine intensifies, the open circuit voltage of PV battery basically keeps unchanged. But the short circuit current increases substantially, thus the maximum output power increases substantially.
This MPPT solar can intelligently regulate the working voltage of solar panels, letting the solar panels always work at maximum power point of VA curve. Compared with ordinary solar controller, this MPPT controller can increase the efficiency of PV modules by about 30%.
