PV Rapid Shutdown System (PVRSS) is one of the necessary security factors of disbursed photovoltaic system. Its principal feature is to decrease the voltage of 30cm away from the PV module to beneath 30V inside 30s after the shutdown system is started.When the building where the PV module is placed requires protection or firefighting, it can efficiently forestall viable protection dangers such as electric powered shocks, and defend the lives of preservation 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).
