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
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
The MPPT (Maximum Power Point Tracking) charge controller is the shining star of today's PV systems. These controllers actually detect the optimum operating voltage and amperage of the solar array and match that with the battery bank. The result is an additional 15-30% more power out of your array versus a PWM controller.
