90V Fast Solar Rapid Shutdown System

 Key Features :
  • PV module hastily shutdown meeting NEC 2017 & 2020 (690.12) requirements
  • Bidirectional PLC communication
  • PV module monitoring: on/off status, temperature, voltage, current, electrical electrical energy 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 useful resource of

    PV Rapid Shutdown System (PVRSS) is one of the vital security factors of disbursed photovoltaic system. Its integral attribute is to ward off the voltage of 30cm away from the PV module to under 30V indoors 30s after the shutdown computing laptop is started.When the developing the shut via the use of the PV module is positioned requires renovation or firefighting, it can effectually quit manageable security risks such as electric powered  shocks, and protect the lives of safety personnel and firefighters.

System Components


PV Rapid Shutdown System (PVRSS) is as an desire composed of the following PV all of sudden shutdown devices:

1. Tail Module(FR-PVMS-Txxx): A shortly shutdown module with monitoring, which can all of stunning shut down the PV strings and transmit the archives of the PV strings to the head module with the truely definitely beneficial encouraged beneficial aid of the PLC signal.

2. Head Module(FR-PVMS-Hxx): Controls the tail module with the in fact encouraged definitely beneficial endorsed beneficial aid of the PLC signal, and transmit the archives to the indispensable controller with the triggered in truth really useful beneficial aid of the use of way of RS485.

3. Main Controller(FR-PVMS-Mxxx): Displays the electrical electrical electrical energy and excellent archives of the PV strings, and transmit the data to the cloud platform at the equal time. Users can remotely manipulate it with the aid of way of the cell smartphone smartphone APP(SafeSolar).
