BFS-11 is a module level rapid shutdown device for solar building fire safety.
The emergency button switch is required to initiate the rapid shutdown function, after the button switch connected with BFS-11 devices by signal cables.
This communication type is the most reliable one, ensure the PV system has RSD function in decades and the panel can be switched off to a safe voltage level in case of emergency at the lowest power consumption.
A RSD solution is good for existing solar rooftop or new installations.
How the solution works?
Each BFS-11 device operates two solar modules, the modules in series go to inverter sting as usual. The only difference is the communication signaling cables connect the BFS-11 in series and go to the button switch complete the RSD solution.
A complete RSD solution:
Automatic shutdown the panels when there is a temperature in the area higher than 85°C detected.
Automatic shutdown the panels when the power supply loss in the button switch box.
The fireman and people can manual the button switch to shutdown the panels when there is an emergency.
