WS-MPPT15 15A solar controller (also known as WELLSEE intelligent solar charge controller, solar charge controller, PV controller) applies in solar energy photovoltaic systems, which coordinates the working of solar panels, batteries and loads..It 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 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 MPPT controller makes PV battery always work at the maximum power point, thus outputs the power point of 75W (the maximum power point).
