Three-phase hybrid solar power system combining 14.7 kW PV generation (three strings of Jinko 700W panels), 60 kWh Felicity battery storage, and three IVEM8048 inverters feeding a 380V/50Hz utility grid with automatic transfer switching. DC strings route through isolators and surge protection to inverters, which synchronize on a common AC bus before distribution through an ATS, RCCB, and main MDB busbar to priority and apartment loads. The architecture implements TT earthing with comprehensive protection: AC surge protection, DC isolators, battery fuses, and circuit breakers rated for 125A main feeds and 32–63A branch circuits. This design balances solar self-consumption, battery backup, and grid stability for a multi-unit residential installation with load prioritization and 30 mA residual current protection. Fork this diagram on Diagrams.so to customize panel counts, inverter ratings, battery chemistry, or load distribution for your site-specific microgrids. Advanced practitioners can extend this topology with energy management systems, demand-side management, or grid-forming inverter controls.
