Abstract
Disclosed are a photovoltaic system and its rapid shutdown method. The photovoltaic system includes a photovoltaic array including a photovoltaic array panel and a shutdown device, a junction box and an inverter, the shutdown device is electrically connected to the photovoltaic array panel and is connected to the inverter; the photovoltaic system further includes a shutdown device controller, which is coupled to the high voltage wires, and is configured for receiving a first detection signal reflecting a state of the AC side of the inverter, determining whether the AC side of the inverter is in a power-off state, outputting a first power-off signal when the AC side of the inverter is in the power-off state, and transferring the first power-off signal to the shutdown device; and the shutdown device receives the first power-off signal and prohibits the electric energy from transferring to the inverter.
