Off-grid residences equipped with renewable energy sources (RES), battery storage systems (BSS), and electric vehicles (EVs) constitute a sustainable and self-sufficient ecosystem. This integration helps to achieve energy independence and reduces the reliability on fossil fuels. Existing systems, comprising RES, BSS, and EV, employ an increased number of power conversion stages and power

This paper proposes a reconfigurable power electronic system (RPES) powered by solar photovoltaic (PV) and BSS for charging EVs and supplying residential DC loads (RDCLs) uninterruptedly. With the ability to reconfigure, the proposed system can operate in nine distinct modes with two PE switches and reduced power conversion stages compared to existing systems. The system reconfigures itself using five relays. The proposed system enables vehicle-to-home operation by supplying the RDCLs from EV in the absence of PV and BSS. PV charges the EV during the day, while BSS charges it at night. The dspic30F4011 controller determines the operating mode of the RPES based on the inputs it receives. The controller triggers the relays after the mode selection, which allows the interface to reconfigure automatically. In the same manner, the controller selects the appropriate control logic and transmits triggering pulses to the PE switches in accordance with the operating modes. A laboratory prototype has been created to assess the system's performance under both steady-state and transient conditions. The results indicate an average efficiency of 96.9%.
