Three-phase hybrid solar power system combining 14.7kW PV generation across three strings with 60kWh battery storage and automatic utility grid switching. DC power from Jinko PV arrays flows through string isolators and surge protection to three IVEM8048 inverters synchronized on phases L1, L2, and L3, feeding an AC bus connected to a 48V Felicity battery bank. The system uses automatic transfer switch (ATS) logic to prioritize solar and battery power for ground floor loads while providing 5A backup capacity to apartment circuits, with comprehensive protection via MCCBs, RCCBs, SPD devices, and energy metering. Engineers can fork this diagram to customize load distribution, adjust battery capacity, or model different inverter configurations for residential or small commercial microgrids. The TT earthing scheme and 30mA RCD protection ensure compliance with IEC 60364 standards for safety-critical installations.
