PV Rapid Shutdown System (PVRSS) is one of the necessary protection elements of disbursed photovoltaic system. Its integral attribute is to minimize the voltage of 30cm away from the PV module to below 30V indoors 30s after the shutdown machine is started.When the developing the area the PV module is located requires protection or firefighting, it can successfully stop manageable security dangers such as electric powered powered shocks, and defend the lives of renovation personnel and firefighters.

System Components

PV Rapid Shutdown System (PVRSS) is as an alternative composed of the following PV hastily shutdown devices:

1. Safety Controller(FR-PVMS-Txxx): A rapid shutdown module with monitoring, which can rapidly shut down the PV strings and transmit the statistics of the PV strings to the head module through way of the use of the PLC signal.

2. PLC Transceiver(FR-PVMS-Hxx): Controls the tail module by the utilization of the PLC signal, and transmit the archives to the predominant controller with the really helpful resource of RS485.

3. Monitor(FR-PVMS-Mxxx): Displays the power and one-of-a-kind data of the PV strings, and transmit the facts to the cloud platform at the same time. Users can remotely manipulate it with the resource of way of the utilization of the  APP(SafeSolar).
