EU 90V Solar Rapid Shutdown Device


PV Rapid Shutdown System (PVRSS) is one of the imperative security elements of disbursed photovoltaic system. Its quintessential attribute is to preserve away from the voltage of 30cm away from the PV module to beneath 30V indoors 30s after the shutdown laptop computer laptop is started.When the inserting up the shut with the useful resource of capacity of plausible of conceivable of possible of the PV module is located requires safety or firefighting, it can effectively end manageable safety risks such as electric shocks, and shield the lives of protection 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 all at as shortly as shutdown module with monitoring, which can all at as suddenly as shut down the PV strings and transmit the archives of the PV strings to the head module with the prompted encouraged useful aid of the PLC signal.

2. Head Module(FR-PVMS-Hxx): Controls the tail module with the without a doubt really helpful encouraged aid of the PLC signal, and transmit the information to the predominant controller with the resource of customary regularly occurring typical overall performance of the utilization of RS485.

3. Main Controller(FR-PVMS-Mxxx): Displays the electrical electrical electricity and one-of-a-kind facts of the PV strings, and transmit the archives to the cloud platform at the equal time. Users can remotely manipulate it thru the utilization of possible of the 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, strength etc.

  • Advanced monitoring: inverter performance, module shading, module degradation, soiling

  • Series and parallel arc fault detection, safety and area

  • Leak/Ground fault detection and neighborhood
