Note: Hybrid inverters manage PV, battery, grid, and load simultaneously. Typical C-rate limit is 0.5C-1C for lithium batteries.

Reference

Min Inverter = max(PV_capacity, Peak_load) × 1.1 Usable Battery = Capacity × DoD (90%) C-Rate = Battery Power / Battery Capacity PV-to-Battery Ratio = PV_capacity / Battery_kWh
