Product Description

*0A *0A Intelligent MPPT Solar Controller, *2V/*4V Auto Switch Solar Controler to Increase Solar Module Efficiency *0%



Brief Introduction:

WFWS-MPPT*0 *0A solar controller (also known as 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 is equipped with temperature compensation function, can increase the efficiency of PV modules by *0%**0% and can observably prolong the life span of storage battery. This MPPT solar controllers *0A**0A include *2V series, *4V series and *8V series.



MPPT Principle:

Photovoltaic Solar Charge Controller MPPT design Solar Controller is a solar charge controller with Maximum Power Point Tracking. It is specially designed to work with all established module technologies and is optimized for solar systems with module voltages higher than the battery voltage.



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 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 around *0%.



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 *0%**0%.



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 makes PV battery work on *2V, only outputs a power point of *3W (a general power point). However, for the MPPT controller, it makes PV battery always work at the maximum power point, thus outputs the power point of *5W (the maximum power point).
