Description


PV Rapid Shutdown System (PVRSS) is one of the essential protection elements of allotted photovoltaic system. Its essential characteristic is to limit the voltage of 30cm away from the PV module to beneath 30V inside 30s after the shutdown system is started.When the constructing the place the PV module is placed requires upkeep or firefighting, it can efficaciously forestall conceivable protection risks such as electric powered shocks, and defend the lives of protection personnel and firefighters.

PV Rapid Shutdown System (PVRSS) is ordinarily composed of the following PV speedy shutdown devices:


1. Tail Module(FR-PVMS-Txxx): A fast shutdown module with monitoring, which can shortly shut down the PV strings and transmit the records of the PV strings to the head module via the PLC signal.

2. Head Module(FR-PVMS-Hxx): Controls the tail module with the aid of the PLC signal, and transmit the facts to the fundamental controller by way of RS485.

3. Main Controller(FR-PVMS-Mxxx): Displays the energy and different data of the PV strings, and transmit the facts to the cloud platform at the identical time. Users can remotely manage it through the cellular telephone APP(SafeSolar).
