WS-MPPT 20A 30A Wellsee Solar Charge Controller

Solar Charge Controller,
allows PV panels to outputs more Power by adjusting working condition of the electrical module
Solar Charge Controller
This WS-MPPT30 30A solar controller (also known as WELLSEE intelligent solar charge controller, solar charge controller, PV 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%. 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).

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 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%.
