Module Level Rapid Shutdown BFS-21

The BFS-21 is designed and developed as the most reliable module level rapid shutdown device for solar building fire safety and meeting the NEC requirements.

Operates SINGLE standard PV module (>=40V) or TWO modules (<40V).

The BFS-21 complies with NEC 2017&2020 690.12 rapid shutdown requirements when work with the SunSpec signal transmitter BFT-01 or an inverter with built-in transmitter, in non-interference with the inverter AFCI.
