Solar Charge Controller Overview

Solar Charge Controller: Micro Controller Unit utilizing dedicated software and SCM for precise control; By using of the battery discharge rate modified characteristic to achieve accurate discharge control. Discharge Cut-off discharge voltage is the control point modified by the discharge curve. So it can eliminate the inaccuracy of the pure over discharge voltage control, and it also suit the battery feature that is to say different discharge rate has different cut-off voltage.
