Availability:


     PV Rapid Shutdown System (PVRSS) is one of the necessary protection elements of disbursed photovoltaic system. Its essential characteristic is to decrease the voltage of 30cm away from the PV module to under 30V inside 30s after the shutdown system is started.When the constructing the place the PV module is placed requires protection or firefighting, it can efficiently stop viable protection dangers such as electric powered shocks, and shield the lives of protection personnel and firefighters.

PV Rapid Shutdown System (PVRSS) is instead composed of the following PV swiftly 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).
