Module level Rapid shutdown device BFS-21


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.

BFS-21 FEATURES 
Shutdown panel to 0V at microsecond 
Plug and Play Easy Installation
PLC control signaling 
PVRSS with multiple inverters
Over temperature protection Automatic shutdown
Patents pending
25 years warranty
