BFS-11 is a module level rapid shutdown device for solar rooftop and 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 communication cables.

The communication type is the more reliable than PLC, 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 good for existing solar rooftop or new installations.
