The answer is to bypass the inverter while the grid is available and automatically connect the circuits you want if there's an outage. For this we use an electrically operated switch, a relay or a contactor in electrical jargon. . Among these, the AC contactor is a small but essential device that enables precise control over power flow between inverters, grids, and loads. Without proper control, renewable systems can suffer from voltage fluctuations, system instability, and potential equipment failure. Power generation The generator in a power station generates 3-phase electricity.
