BENY - Model BFS-A1 - Module-Level Rapid Shutdown Device With Aluminum Enclosure

• Module Level Rapid Shutdown
• Manual Shutdown by Button Switch
• Automatic Shutdown on AC Power Loss
• Improved Heat Dissipation with Aluminum Casing
• Over temperature (>100℃) Automatic Shutdown
• Compatible with Most String Inverters and Panels
• No cross-talk with Inverter or WIFI
• Shutdown Panels to 0V at microsecond (μs) level
• 10 Years Warranty

• 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.
• With automatic shutdown at temperatures exceeding 100℃, it requires no setup, is compatible with any string inverter, and offers flexibility in positioning.
• The emergency switch unit allows for Manual Emergency Shutdown and responds to local or area grid shutdowns.

For NEC 2017/2020 compliance, if the PV panel >40V, 1-to-1 configuration should be required in order to meet regulatory compliance.
The diagram above illustrates a typical 1-to 1 configured BFS protected installation using three solar panels and three BFS-A1. One more thing on the rooftop is the connection of BFS-A1 and the button switch via a communication cable.

• Automatically shut down the panels upon detecting a temperature in the area exceeding 100℃.
• Automatically shut down the panels in the button switch box in case of AC power supply loss.
• The firefighter can manually use the button switch to shut down the panels in case of an emergency.
