When the utility grid is powered off, the grid side is equivalent to a short-circuit state, and the grid-connected inverter will be automatically protected due to overload. When the microprocessor detects an overload, in addition to blocking the SPWM signal, it will also disconnect the circuit breaker connected to the grid. At this time, if the solar cell array has energy output, the inverter will...
