NEC2020 80V RSD Device

 
 
Availability:


        PV Rapid Shutdown System (PVRSS) is one of the imperative security elements of disbursed photovoltaic system. Its integral attribute is to limit the voltage of 30cm away from the PV module to beneath 30V indoors 30s after the shutdown system is started.When the placing up the neighborhood the PV module is located requires protection or firefighting, it can efficiently end manageable protection risks such as electric powered powered powered shocks, and protect 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 fast shutdown module with monitoring, which can unexpectedly shut down the PV strings and transmit the files of the PV strings to the head module with the aid of the PLC signal.
2. Head Module(FR-PVMS-Hxx): Controls the tail module via the PLC signal, and transmit the facts to the predominant controller by means of the usage of RS485.
3. Main Controller(FR-PVMS-Mxxx): Displays the electrical energy and special records of the PV strings, and transmit the information to the cloud platform at the equal time. Users can remotely manipulate it through the phone smartphone APP(SafeSolar).

Key Features 


  • PV module speedy shutdown assembly NEC 2017 & 2020 (690.12) necessities

  • Bidirectional PLC verbal exchange

  • 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 area

  • Leak/Ground fault detection and place
