Working Principle Video of 8.5kW/15kWh Hybrid Grid PV Energy Storage System

8.5kW/15kWh hybrid PV-ESS converts solar power into DC electricity via PV panels and feeds it into the hybrid inverter. Solar power supplies household loads first, and excess energy is stored in three 5kWh batteries. It works in grid-tied mode for self-consumption when grid is available. Once grid fails, it automatically switches to off-grid mode. PV and batteries jointly power loads to guarantee uninterrupted electricity for areas with unstable grids.
