WELLSEE MPPT30 battery charger controller  This WS-MPPT battery chargercontroller(also known as WELLSEE intelligent solar chargecontroller, solar controller, PVcontroller) 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 solarcontroller, this MPPTcontrollercan increase the efficiency of PV modules by 10%-30%. WELLSEE WS-MPPT solar controllers 10A--60A include 12V series, 24V series and 48V series.

MPPT advantage:

Maximum Power Point Tracking (MPPT in short) system is a system which allows PV panels to outputs more Power by adjusting working condition of the electrical module. In Figure1  A indicates that the ordinary controller, which makes PV battery work on 12V ,only outputs a power point of 53W (a general power point), B indicates that MPPTcontrollermakes PV battery always work at the maximum power point, thus outputs the power point of 75W (the maximum power point).
