TYPICAL OPEN CIRCUIT VOLTAGE
Inverter AC side voltage is high
According to the requirements of the overvoltage/undervoltage protection on the AC output side of the photovoltaic power grid-connected inverter technical specification (NB/T32004-2018): When the voltage at the AC output end of the inverter exceeds the allowable voltage range of the power grid, the inverter is allowed to disconnect the power supply to the power grid, and a warning signal should be issued when it is disconnected.
