Battery Reverse Polarity Connection Protection
Schematic Diagram: Picture 2 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: ???
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
