Availability:


    PV Rapid Shutdown System (PVRSS) is one of the essential safety elements of disbursed photovoltaic system. Its quintessential attribute is to ward off the voltage of 30cm away from the PV module to beneath 30V indoors 30s after the shutdown computing laptop computer is started.When the growing the shut with the aid of the use of the PV module is placed requires renovation or firefighting, it can effectually cease manageable safety dangers such as electric powered  shocks, and defend the lives of protection personnel and firefighters.

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

1. Tail Module(FR-PVMS-Txxx): A rapidly shutdown module with monitoring, which can all of lovely shut down the PV strings and transmit the archives of the PV strings to the head module with the truely honestly really helpful prompted really useful useful resource of the PLC signal.

2. Head Module(FR-PVMS-Hxx): Controls the tail module with the in truth prompted honestly advisable encouraged really useful resource of the PLC signal, and transmit the archives to the fundamental controller with the induced in reality definitely beneficial really helpful resource of the use of way of RS485.

3. Main Controller(FR-PVMS-Mxxx): Displays the electrical electrical electrical strength and fantastic archives of the PV strings, and transmit the records to the cloud platform at the equal time. Users can remotely manipulate it with the useful resource of way of the cellphone smartphone smartphone APP(SafeSolar).
