solar controller MPPT

1.MPPT:maximum power point tracking
2Using MPPT controller will increase at least10%to15% change efficiency compare with before
Description:
If the balance is not good solar panel voltage and the battery voltage then increase
200% or 300% exchange efficiency is possible.
Use MPPT controller, the solar panel have enough voltage to concert the battery voltage
So use MPPT controller could increase exchange efficiency at least 10%to15%
But the MPPT controller not the glamour equipment for solar cell system.the MPPT
controller is the abbreviate of “max power solar panel controller track.Just like its name,it is a system of track the max power point.
