90V Automatic Rapid Shutdown Device

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

PV Rapid Shutdown System (PVRSS) is one of the fundamental safety elements of disbursed photovoltaic system. Its necessary attribute is to ward off the voltage of 30cm away from the PV module to underneath 30V indoors 30s after the shutdown computing machine is started.When the growing the shut through the use of the PV module is placed requires renovation or firefighting, it can effectually cease manageable safety risks such as electric powered shocks, and defend the lives of protection personnel and firefighters.

System Components


PV Rapid Shutdown System (PVRSS) is as an choice composed of the following PV unexpectedly shutdown devices:

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

2. Head Module(FR-PVMS-Hxx): Controls the tail module with the in truth recommended really useful recommended useful resource of the PLC signal, and transmit the files to the essential controller with the prompted in reality beneficial useful resource of the use of way of RS485.

3. Main Controller(FR-PVMS-Mxxx): Displays the electrical electrical electricity and first-rate archives of the PV strings, and transmit the information to the cloud platform at the equal time. Users can remotely manipulate it by way of the cellular telephone smartphone APP(SafeSolar).
