BFS-11 is a UL1741 listed module level rapid shutdown device for solar building fire safety, inherently compliant with NEC 2014, NEC2017 690.12 requirements.
That is the RSD solution we are offering can work with all solar modules and inverters.
The 2017 National Electric Code (NEC) requires the solar PV installations on or in buildings to have a module level rapid shutdown function in case of emergency.
And the initiation device(s) shall initiate the rapid shutdown function of the PV system.
The device “off” position shall indicate that the rapid shutdown function has been initiated for all PV systems connected to that device. An initiation device(s) shall be located at a readily accessible location outside the building.
The solar installers and owners need a reliable and durable RSD solution can keep function during the whole PV panels’ decades lifetime, a simply RSD solution with emergency button switch as one of the initiation devices.
BFS-11 is a UL1741 listed module level rapid shutdown device for solar building fire safety, inherently compliant with NEC 2014, NEC2017 690.12 requirements.
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 good for existing solar rooftop or new installations.
Each BFS-11 device operates multiple solar modules total voltage up to 120V, 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.
