Germany 80V PV Rapid Shutdown Device

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

      PV Rapid Shutdown System (PVRSS) is one of the essential protection factors of disbursed photovoltaic system. Its vital attribute is to ward off the voltage of 30cm away from the PV module to below 30V indoors 30s after the shutdown machine is started.When the creating the shut by using the PV module is placed requires renovation or firefighting, it can correctly quit manageable safety dangers such as electric powered powered powered powered powered powered shocks, and defend the lives of protection personnel and firefighters.

System Components


PV Rapid Shutdown System (PVRSS) is rather composed of the following PV rapidly shutdown devices:

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

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

3. Main Controller(FR-PVMS-Mxxx): Displays the electrical electricity and fantastic records of the PV strings, and transmit the information to the cloud platform at the equal time. Users can remotely manage it through the mobilephone smartphone APP(SafeSolar).
