90V NEC 690.12 Rapid Shutdown System

 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, electrical strength etc.
  • Advanced monitoring: inverter performance, module shading, module degradation, soiling
  • Series and parallel arc fault detection, security and location
  • Leak/Ground fault detection and shut with the aid of

PV Rapid Shutdown System (PVRSS) is one of the indispensable protection factors of disbursed photovoltaic system. Its vital attribute is to ward off the voltage of 30cm away from the PV module to beneath 30V indoors 30s after the shutdown computing gadget is started.When the developing the shut thru the use of the PV module is located requires renovation or firefighting, it can efficaciously quit manageable protection dangers such as electric powered  shocks, and guard the lives of security personnel and firefighters.

System Components


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

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

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

3. Main Controller(FR-PVMS-Mxxx): Displays the electrical electrical strength and notable archives of the PV strings, and transmit the statistics to the cloud platform at the equal time. Users can remotely manipulate it by the cellphone smartphone APP(SafeSolar).
