MPPT principle:

The maximum power point is mainly affected by the ambient temperature and the intensity of sunshine.
The intensity of sunshine being constant, the maximum output power decreases with the rise of the
Temperature. The temperature being constant, when the sunshine intensifies, the open circuit voltage of
PV battery basically keeps unchanged. But the short circuit current increases substantially, thus the
Maximum output power increases substantially.

This MULTIFIT 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:

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)
