WELLSEE mppt solar controller WS-MPPT60 50A 48V
Mppt solar controller
16pcs/cartonWellsee mppt solar controller WS-MPPT60 50A (also known as wellsee solar controller,chargecontroller,solar charge controller,solar regulator,pvcontroller,power 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 mppt solar controller 10A--60A includes 12V series, 24V series and 48V series.MPPT advantage:Maximum Power Point Tracking (MPPT in short) system allows PV panels to output more Power by adjusting working condition of the electrical module. In Figure1 A indicates that the working state of ordinary controller, that is PV battery working on 12V ,only outputting a power point of 53W (the general power point), B indicates that MPPT controller makes PV battery always work at the maximum power point, thus outputting the power point of 75W (the maximum power point).Product features:Applicable to various types of batteries,MPPT functionTemperature sensor battery charging compensationOverload protection (automatic restoration)Overcharge protectionShort circuit protection (automatic restoration) ,Lightning protectionReverse discharge protectionReverse polarity connection protection (automatic restoration)Under voltage protectionMPPT principle: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-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 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%-30%.
