RAPID SHUTDOWN DEVICE BFS-A1

BFS-A1, a module-level solar rapid shutdown device, ensures fire safety for solar installations by maintaining continuous rapid shutdown functionality throughout the PV system’s lifespan.

Highlights:
Technical certification :

PV Rapid Shutdown Device Solution

Each BFS-A1 device can hold solar modules output max: 1500V total, the modules connect in series as solar string goes to inverter as PV system designing. The connection of BFS-A1/BFS-A2 RSD and button switch is via communication cable.
