MPPT controller China manufactory

This WS-MPPTSolar energy controller (also known as WELLSEE intelligent solar chargecontroller, solar charge controller, PV controller) can intelligently regulatethe working voltage of solar panels, letting the solar panels always work atMaximum Power Point of V-A curve. Compared with standard solar controller, thisMPPT controller can increase the efficiency of PV modules by 10%-30%. WELLSEEWS-MPPT solar controllers 10A--60A include 12V series, 24V series and 48Vseries.

MPPTadvantage:

Maximum PowerPoint Tracking (MPPT in short) system allows PV panels to output more Power byadjusting working condition of the electrical module. In Figure1  Aindicates that the working state of ordinary controller, that is PV batteryworking 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 powerpoint, thus outputting the power point of 75W (the maximum power point).

 MPPTprinciple:

The maximumpower point is mainly affected by the ambient temperature and the intensity ofsunshine. With the intensity of sunshine being constant, the maximum outputpower decreases with the rise of the temperature. The temperature beingconstant, when the sunshine intensifies, the open circuit voltage of PV batterybasically keeps unchanged. But the short circuit current increasessubstantially, thus the maximum output power increases substantially.

This WS-MPPTSolar energy controller can intelligently regulate the working voltage of solarpanels, letting the solar panels always work at Maximum Power Point of V-Acurve. Compared with ordinary solar controller, this MPPT controller canincrease the efficiency of PV modules by about 30%.

However, dueto many different factors, such as the difference in solar panel making, thechange of the sun illuminance, change of temperature, the efficiency of thecontroller etc., the actually available increased rate is 10%-30%.
