Description

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.

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.
