MPPT20 20A solar charge 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 ordinary solar controller, this MPPT controller can increase the efficiency of PV modules by 10%~30%. MPPT solar controllers 10 Amp—60 Amp 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. the ordinary controller, which makes PV battery work on 12V ,only outputs power of 53W (a general power point); MPPT controller makes PV battery always work at the maximum power point, thus outputs power of 75W (the maximum power point).

MPPT principle:
The maximum power point is mainly affected by the ambient temperature and the intensity of sunshine. This MPPT solar 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 ordinary solar controller, this MPPT controller can increase the efficiency of PV modules by about 30%.
However, due to many different factors, such as the difference in solar panel making, the change the Sun illuminance, change in temperature, the efficiency of the controller etc., the actually available increased rate is 10%~30%.
