Solar Panel level rapid shutdown BFS series is developed for solar roof and building safety. UL listed and compliant with NEC2017
A cost-efficiency and purely rapid shutdown solution to meet NEC2017 690.12
In cases of fire in buildings with solar installations present, the panels continue to produce energy as long as there is daylight present, so it is critical that the live DC wiring in and around the building is isolated as close to the panels as possible. The BFS rapid shutdown units isolate the DC wiring directly behind the panels.
Each BFS unit operates two solar panels and is positioned behind the panels and attached to the panel mounting frame. Good enough for 800W DC power, so is suitable for most types of solar panel currently available on the market.
The BFS units are connected in series using plug-and-play connectors and the signal cable is then taken to the Emergency Switch, which can be situated anywhere easy to reach. Very easy for installation.
As soon as the Emergency Switch is activated, the BFS "shuts-down" the solar panels by isolating all the DC cabling in the building right back to the rear of the panel installation. In a larger, multi-storey building, a number of Emergency Switch units can be located in multiple zones around the building, or on different floors as required.
