Abstract: Efficient solar energy conversion necessitates advanced charge controllers. This paper presents the design and construction of a smart DC-DC charge controller for solar charge stations. The controller, employing Maximum Power Point Tracking (MPPT), efficiently charges 12V-48V batteries up to 20A, maximizing power extraction from solar panels. This paper details the design and experimental performance validation of a smart solar charge controller based on the Perturb and Observe (P&O) MPPT algorithm for charging 12V to 48V batteries with a maximum charging current of 20A.

Keywords: Solar Charge Controller, DC-DC Converter, MPPT (Maximum Power Point Tracking), Battery Charging.
