Thailand 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, power etc.
  • Advanced monitoring: inverter performance, module shading, module degradation, soiling
  • Series and parallel arc fault detection, security and location
  • Leak/Ground fault detection and neighborhood

        PV Rapid Shutdown System (PVRSS) is one of the critical protection elements of disbursed photovoltaic system. Its fundamental attribute is to restrict the voltage of 30cm away from the PV module to beneath 30V internal 30s after the shutdown system is started.When the creating the neighborhood the PV module is located requires renovation or firefighting, it can correctly stop feasible protection risks such as electric powered powered powered shocks, and guard the lives of security personnel and firefighters.

System Components


PV Rapid Shutdown System (PVRSS) is notably composed of the following PV fast shutdown devices:

1. Tail Module(FR-PVMS-Txxx): A speedy shutdown module with monitoring, which can swiftly shut down the PV strings and transmit the archives 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 with the useful resource of the PLC signal, and transmit the information to the imperative controller with the aid of the use of way of RS485.

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