WS-MPPT15 15A solar power controller (also known as WELLSEE intelligent solarcharge controller, solar charge controller, PV controller) can intelligentlyregulate the working voltage of solar panels, letting the solar panels alwayswork at Maximum Power Point of V-A curve. Compared with ordinary solar controller, this MPPTcontroller can increase the efficiency of PV modules by 10%-30%.WELLSEE WS-MPPT solar power controllers 10A--60A include 12V series, 24V seriesand 48V series.

MPPT advantage:

Maximum Power Point Tracking (MPPT in short) system is a system whichallows PV panels to outputs more Power by adjusting working condition of theelectrical module. In Figure1A indicates that the ordinarycontroller, which makes PV battery work on 12V ,only outputs a power point of53W (a general power point), B indicates that MPPT controller makes PV batteryalways work at the maximum power point, thus outputs the power point of 75W (themaximum power point).

The maximum power point is mainly affected by the ambient temperature and theintensity of sunshine. The intensity of sunshine being constant, the maximumoutput power 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-MPPT solar controller can intelligently regulate the working voltageof solar panels, letting the solar panels always work at Maximum Power Point ofV-A curve. Compared with ordinary solar controller, this MPPT controller canincrease the efficiency of PV modules by about 30%.

However, due to many different factors, such as the difference in solar panelmaking, the change the Sun luminance, change in temperature, the efficiency ofthe controller etc., the actually available increased rate is 10%-30%.
