This paper presents a solution for existing power crisis by implementing state of art techniques to tap power from solar energy. The use of Maximum Power Point Tracking (MPPT) technique along with the efficient charge control of the battery helps attaining a maximum output. A digitally controlled DC-DC Buck-boost converter was implemented and connected to Solar PV Array. State of Charge (SOC) of battery is continuously monitored to decide the charging rate of the battery at every instant. Moreover, the dynamic response and SOC are also evaluated using a user-friendly GUI interface which is capable of controlling the system and computing the SOC. An inverter connected to the battery produces an AC voltage which is stepped up to power the domestic load.
