England 90V Solar Rapid Shutdown Device

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

PV Rapid Shutdown System (PVRSS) is one of the imperative protection elements of disbursed photovoltaic system. Its fundamental attribute is to decrease the voltage of 30cm away from the PV module to beneath 30V internal 30s after the shutdown device is started.When the developing the region the PV module is located requires protection or firefighting, it can successfully forestall attainable protection dangers such as electric powered powered powered shocks, and defend the lives of renovation personnel and firefighters.

System Components


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 shortly shut down the PV strings and transmit the facts of the PV strings to the head module by using the PLC signal.

2. Head Module(FR-PVMS-Hxx): Controls the tail module via the PLC signal, and transmit the records to the predominant controller with the aid of RS485.

3. Main Controller(FR-PVMS-Mxxx): Displays the strength and different statistics of the PV strings, and transmit the statistics to the cloud platform at the identical time. Users can remotely manage it by using the cell smartphone APP(SafeSolar).
