Wellsee mppt solar controller WS-MPPT60 50A (also known as wellsee solar controller,chargecontroller,solar charge controller,solar regulator,pv controller,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 PVpanels 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.
