WS-MPPT60 solar controller also known as WELLSEE intelligent solar charge controller, solar charge controller, PV 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 standard solar controller, this MPPT controller can increase the efficiency of PV modules by 10%-30%. WELLSEE WS-MPPTsolar controllers 10A--60A include 12V series, 24V series and 48V series.
Applicable to various types of batteries,
Overload protection (automatic restoration)
Short circuit protection (automatic restoration) ,
Reverse discharge protection
Reverse polarity connection protection (automatic restoration)
Under voltage protection
The maximum power point is mainly affected by the ambient temperature and the intensity of sunshine. With 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 WS-MPPTSolar energy 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 different factors, such as the difference in solar panel making, the change of the sun illuminance, change of temperature, the efficiency of the controller etc., the actually available increased rate is 10%
