Application
The BFS-A1 Monitoring version is a module-level rapid shutdown device designed to enhance fire safety for solar rooftops and buildings. It maintains rapid shutdown functionality throughout the entire lifespan of the solar PV system.
Utilizing a unique POWERBUS communication method, it continuously monitors the temperature, voltage, current, and other data of the Rapid Shutdown Device (RSD) in real-time. This enables immediate observation of RSD status and early detection of issues, facilitating replacement and maintenance, thereby enhancing the safety of the PV power generation system.
The accompanying RSD monitoring equipment is required to utilize monitoring functions. Additionally, the monitoring
equipment is equipped with emergency stop functionality alongside its monitoring capabilities.
Advantage
*Module Level Rapid Shutdown With Monitoring Fuction
*Aluminum Enclosure With Higher Safety
*Manual Shutdown by emergency button
*Level and Better Heat Dissipation Functior
*Automatic Shutdown on AC Power Loss
*Over temperature Automatic Shutdown
*Compatible with most string invertersand panels
*No cross-talk with inverter or WIFI
How the solution works?
The diagram above illustrates a typical 2-to 1 configured BFS protected installation using four solar panels and two BFS-A1. One more thing on the rooftop is the connection of BFS-A1 and the button switch via a communication cable.
A complete RSD solution:
Automatic shut down the panels upon detecting the inside temperature exceeding 100℃.
Automatic 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.
