Feature: The most important feature of this controller is intelligently tracking input voltage from solar panel, which could let solar panel always work at Maximum Power Point of V-A curve. Compared with normal solar charge controller, this MPPT controller could increase efficiency at 10—30%
Schematic Diagram: Picture shows typical 12V battery solar charge system V-A curve.
Normal Solar Charge Controller: Solar Panel works at point A state, the solar panel working voltage is a little higher than battery voltage.
Charge Voltage: UA=13.2V
Charge Current:: IA=9.8A
Charge Power: PA=13.2*9.8=129.36w
Area in drawing: 1+3
MPPT Solar Charge Controller: Solar Panel works at point B state, the solar panel working voltage much higher than battery voltage.
Charge Voltage: UB=18.4V,
Charge Current: IB=9.3A
Charge Power: PB=18.4*9.3=171.12w
Area in drawing: 1+2
Comparison: The power B is more than power A..
P/ PA =(PB— PA)/ PA=32..3%
As a result of different manufacture of solar panels, different solar illumination intensity, different temperature, different efficiency of solar charge controller and so on. The effective power increase rate is 10-30%.
