How to achieve rapid Shutdown (RSD)?

The quick shutdown function requires two devices -- a transmitter and receivers.

The transmitter is responsible for transmitting the quick shutdown power line signal to the DC wire between the PHOTOVOLTAIC module array and the inverter, and the receiver is responsible for detecting the signal on these conductors:

§ When the signal exists, the receiver remains inactive and the components work normally;

§ When the signal disappears, the receiver is responsible for lowering the pv module array voltage below the standard limit voltage within a specified period of time, thus realizing the fast shutdown function.
