12v/24v 30a Mppt Solar Controller

We are offering 12v/24v 30a mppt solar controller ws-mppt30.
Mppt principle:
the maximum power point is mainly affected by the ambient temperature and the intensity of sunshine. This ws-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%.
Mppt advantage:
an ordinary controller, which makes pv battery work on 12v ,only outputs power of 53w (a general power point); the mppt controller makes pv battery always work at the maximum power point, thus outputs power of 75w (the maximum power point).
