Application

BFS-11/BFS-12 is a module level rapid shutdown device offers fire safety for solar rooftop and building, remainsthe rapid shutdown function period the solar PV system whole working life.

 

Emergency button switch is required to initiate the rapid shutdown operating, as a trigger place on the ground and easier to reach.

 

The communication cable on the rapid shutdown device should be connected in series and wire to the button switch.

 

So the button switch can control the BFS rapid shutdown devices.

 

A communication that is no cross-talk with the inverter or WIFl source.

  • BFS12 wiring

How the solution works?

Each BFS-11/BFS-12 device can hold solar modules output at max 120V in total, the modules connect in seriles as solar stringgoes to inverter as PV system designing. One more thing on the rooftop is the connection of BFS-11/BFS-12 RSD and buttonswitch via communication cable.

 

Note: lf your market requires NEC2017/NEC2020 requirement, we recommend one RSD BFS-11 connects 1 panel(≥40V) or2 panels (<40V); BFS-12 connects 2 panels (≥40V) or 4 panels (<40v).

FEATURES/ADVANTAGES

  • RSD Solution

A complete RSD solution

  • Automatic shutdown the panels when there is a temperature in the area higher than 85°C detected.
  • Automatic shutdown the panels when the AC power supply loss in the button switch box.
  • The fireman can manual the button switch to shutdown the panels when emergency.
