Q Fire - Fire Safety Switch for PV Systems
From Fireman Switch for PV Systems – Module String Disconnection
In the Q Fire Switch fireman's switch, all lines from the isolation box on the roof are galvanically separated from the PV generator in the event of a switch. Thus all DC lines in the building are voltage-free. Switching is carried out via the control box, which is ideally located near the inverters or connected to another point on the AC grid.

The AC coupled switch-off has the main advantage that in case of fire, for example, it is not necessary to look for a switch or that it is no longer accessible. By disconnecting the AC mains, the DC lines from the switch box on the roof are also automatically disconnected. If the AC mains is switched on again, the system also automatically restarts.
