Product Description

ZJBENY BFS**1 Module-Level Rapid Shutdown with Emergency Button Switch for Fire Safety CE Certified

BFS**1 is a module-level quick shutdown device for solar roof and building fire safety.

After the push- switch is connected to the BFS**1 device via the signal communication cable, the emergency push- switch is required to initiate the quick shutdown function.

The communication type is more reliable than a PLC, ensuring that the PV system is RSD capable for decades and that the panel is turned off to a safe voltage level in case of emergency with minimal power consumption.

Apply to existing solar roofs or newly installed RSD solutions.

How does the solution work?

Each BFS**1 unit runs two solar modules, with the modules in series entering the inverter as usual.

The only difference is that the communication signal cable is connected in series to BFS**1 and the RSD solution is completed by a push- switch.

Complete RSD solution:

* Automatically close the panel when the temperature is detected above *5°C.

* Automatically close the panel when the power supply in the switch box is interrupted.

* In case of emergency, firefighters and personnel can manually operate the switch to close the panel.
