1. A rapid shutdown device (RSD), comprising:
a logic-and-analog circuit;
an RSD ID storage connected to the logic-and-analog circuit to store an unique RSD ID;
a control command receiving circuit connected to the logic-and-analog circuit to receive and decode a control command, wherein the control command comprises a combination of: an all-RSD turn-on command, a single-RSD turn-on command, and a to-be-tested RSD ID;
a switch circuit connected to the logic-and-analog circuit; and
a bypass circuit connected between two output terminals of the RSD, wherein when the switch circuit is turned off, the bypass circuit is turned on,
wherein,
the logic-and-analog circuit controls the switch circuit according to a decoding result of the control command receiving circuit and the unique RSD ID stored in the RSD ID storage, and
when the switch circuit is turned on, an output voltage received from a photovoltaic module coupled to the RSD is outputted via the RSD.
