Solar MPPT15 15A 12V / 24V
Solar MPPT15 15A (also known as MPPT intelligent solar controller, solar charge controller, solar controller, PV controller) can intelligently regulate the operating voltage of solar panels, letting the solar panel always operate at the maximum power point of the VA curve. Compared to the standard solar controller, this MPPT controller can increase the efficiency of photovoltaic modules by 10% -30%. WS-MPPT solar controllers 10A - 60A 12V include series, 24V and 48V series.
MPPT advantage:
Maximum Power Point Tracking (MPPT for short) is a system that allows photovoltaic panels at the outputs More power by adjusting the operating mode of the electrical unit. Figure 1A shows that the regular controller, which makes the PV battery operated at 12V, outputs only a 53W power point (a general power point), B shows that the MPPT controller makes a PV battery always operate at the maximum power point, thus outputting at a power point of 75W (the maximum power point).

MPPT principle:
The maximum power point is mainly affected by the ambient temperature and the intensity of the sunshine. The intensity of the sunshine is constant, the maximum output power decreases with increasing temperature. The temperature is constant when the sunshine intensifies, the open circuit voltage of the photovoltaic battery keeps virtually unchanged. But the short circuit current increases significantly, resulting in the maximum output power increases significantly.
This WS-MPPT solar MPPT can intelligently adjust the operating voltage of solar panels, leaving the solar panel always running at the maximum power point of the VA curve. Compared to the standard solar controller, this MPPT controller can increase the efficiency of photovoltaic modules by about 30%.
However, due to many different factors, such as the difference in solar panel reception, the change in Sun lighting intensity, temperature change, the efficiency of the controller, etc., the actually available increased rate is 10% -30%.
