Product Description

PV Rapid Shutdown System (PVRSS) is one of the fundamental safety factors of disbursed photovoltaic system. Its essential attribute is to reduce the voltage of 30cm away from the PV module to under 30V indoors 30s after the shutdown laptop is started.When the growing the place the PV module is placed requires safety or firefighting, it can correctly quit manageable safety risks such as electric shocks, and protect the lives of renovation personnel and firefighters.

System Components

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

1. Safety Controller(FR-PVMS-Txxx): A rapid shutdown module with monitoring, which can rapidly shut down the PV strings and transmit the statistics of the PV strings to the head module through way of the use of the PLC signal.

2. PLC Transceiver(FR-PVMS-Hxx): Controls the tail module by the utilization of the PLC signal, and transmit the archives to the predominant controller with the really helpful resource of RS485.

3. Monitor(FR-PVMS-Mxxx): Displays the power and one-of-a-kind data of the PV strings, and transmit the facts to the cloud platform at the same time. Users can remotely manipulate it with the resource of way of the utilization of the APP(SafeSolar).
