Philippines 90V Solar Rapid Shutdown Device

Key Features 
  • PV module rapid 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, protection and location 
  • Leak/Ground fault detection and location

PV Rapid Shutdown System (PVRSS) is one of the essential safety factors of disbursed photovoltaic system. Its critical attribute is to reduce the voltage of 30cm away from the PV module to underneath 30V interior 30s after the shutdown system is started.When the creating the location the PV module is positioned requires safety or firefighting, it can correctly prevent manageable safety risks such as electric powered shocks, and shield the lives of renovation 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 quick shutdown module with monitoring, which can quickly shut down the PV strings and transmit the statistics of the PV strings to the head module via the use of the PLC signal.

2. Head Module(FR-PVMS-Hxx): Controls the tail module by using the PLC signal, and transmit the archives to the predominant controller with the useful resource of RS485.

3. Main Controller(FR-PVMS-Mxxx): Displays the power and one-of-a-kind facts of the PV strings, and transmit the facts to the cloud platform at the same time. Users can remotely manipulate it by way of the usage of the mobile smartphone APP(SafeSolar).
