What is MPPT 2017-11-16 15:20:09

MPPT-The maximum power point tracking (system is an electrical module by adjusting the working state of the photovoltaic panel can output more power to the electrical system of solar panels from DC effectively stored in the storage battery, can effectively solve the conventional power grid can not cover the remote area and tourism area life and industrial use of electricity that does not produce environmental pollution.


To charge the battery, the output voltage of the solar panel must be higher than the current voltage of the battery. If the voltage of the solar panel is lower than the voltage of the battery, then the output current will be close to 0. So, for safety's sake, the peak voltage (Vpp) of the solar panel is about 17V at the time of manufacturing the solar panel, which is set at the ambient temperature of 25 degrees C. When the weather is very hot, the peak voltage of solar panel Vpp will drop to about 15V, but in cold weather, the peak voltage of solar energy Vpp can reach 18V.

100A Solar Charge And Discharge Controller

Now, let's go back and compare the difference between the MPPT solar controller and the traditional solar controller. The traditional solar charging and discharging controller is a bit like a manual transmission. When the engine speed increases, if the gear box does not increase accordingly, it will affect the speed. But for the MPPT solar controller, charging parameters are set in the factory before, that is, the MPPT controller will power the largest real-time tracking of solar panels, to play the maximum effect of solar panels. The higher the voltage, the maximum power tracking, you can output more power, so as to improve the efficiency of charging. In theory, the solar power generation system using MPPT controller will be 50% higher than the efficiency of the traditional, but according to our practical tests, due to the impact of the surrounding environment and energy losses, the final efficiency can be increased by 20%-30%.


In this sense, the MPPT solar charging and discharging controller is bound to eventually replace the traditional solar controller
