Description
System Components
PV Rapid Shutdown System (PVRSS) is ordinarily composed of the following PV speedy shutdown devices:
1. Tail Module(FR-PVMS-Txxx): A fast shutdown module with monitoring, which can shortly shut down the PV strings and transmit the records of the PV strings to the head module via the PLC signal.
2. Head Module(FR-PVMS-Hxx): Controls the tail module with the aid of the PLC signal, and transmit the facts to the fundamental controller by way of RS485.
3. Main Controller(FR-PVMS-Mxxx): Displays the energy and different data of the PV strings, and transmit the facts to the cloud platform at the identical time. Users can remotely manage it through the cellular telephone APP(SafeSolar).
