Product Description

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%

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%
