PV Rapid Shutdown System (PVRSS) is one of the important safety components of distributed photovoltaic system. Its main function is to reduce the voltage of 30cm away from the PV module to below 30V within 30s after the shutdown device is started.When the building where the PV module is located requires maintenance or firefighting, it can effectively prevent potential safety hazards such as electric shocks, and protect the lives of maintenance personnel and firefighters.

System Components


PV Rapid Shutdown System (PVRSS) is mainly composed of the following PV rapid shutdown devices:

1. Tail Module(FR-PVMS-Txxx): A rapid shutdown module with monitoring, which can quickly shut down the PV strings and transmit the information of the PV strings to the head module by the PLC signal. 

2. Head Module(FR-PVMS-Hxx): Controls the tail module by the PLC signal, and transmit the information to the main controller by RS485.

3. Main Controller(FR-PVMS-Mxxx): Displays the power and other information of the PV strings, and transmit the data to the cloud platform at the same time. Users can remotely control it by the mobile phone APP(SafeSolar).
