USA 80V PV Rapid Shutdown Device

 Key Features :
  • PV module shortly shutdown assembly NEC 2017 & 2020 (690.12) requirements
  • Bidirectional PLC communication
  • PV module monitoring: on/off status, temperature, voltage, current, energy etc.
  • Advanced monitoring: inverter performance, module shading, module degradation, soiling
  • Series and parallel arc fault detection, safety and location
  • Leak/Ground fault detection and nearby

       PV Rapid Shutdown System (PVRSS) is one of the critical protection elements of disbursed photovoltaic system. Its imperative attribute is to ward off the voltage of 30cm away from the PV module to under 30V indoors 30s after the shutdown device is started.When the developing the close by the PV module is positioned requires renovation or firefighting, it can successfully cease manageable security risks such as electric powered shocks, and protect the lives of safety personnel and firefighters.

System Components


PV Rapid Shutdown System (PVRSS) is surprisingly composed of the following PV quickly shutdown devices:

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

2. Head Module(FR-PVMS-Hxx): Controls the tail module with the beneficial useful resource of the PLC signal, and transmit the data to the integral controller with the useful resource of the use of way of RS485.

3. Main Controller(FR-PVMS-Mxxx): Displays the electrical strength and extraordinary data of the PV strings, and transmit the facts to the cloud platform at the equal time. Users can remotely control it thru the cell smartphone APP(SafeSolar).
