QFireBIG fire switch for PV systems in accordance with IEC 60947-3
The QFireBIG Box is suitable for individual standard construction or project-specific for a customized application. We take other customer-specific requirements into account and thus also offer the easiest to install variant for retrofitting existing PV systems. All individual requirements are taken into account. QFire BIG is independent of the manufacturer of the modules or inverters, can be equipped with overvoltage protection and is supplied in a high-quality plastic or metal housing as required.
- Safe disconnection of the PV generator even in an emergency
- Complete set; modularly expandable and easy to install
- Suitable for retrofitting
- AC-coupled, can therefore be triggered at any time via the mains supply
- Switches back on automatically after a power failure
- Arc-free switching thanks to modern switching technology
- Control box can be switched on and off using an external key switch
- Status can be transmitted to the alarm center via a potential-free contact
Optional mit Überspannungsschutz, geeignet für Brandmeldeanlage
The central emergency shutdown for PV systems is suitable for a fire alarm system and can be connected to the fire alarm control panel.
The system can be switched off via an external switch.

Central emergency shutdown for PV systems, customized variants adapted to the respective system
Suitable for fire alarm system, can be connected to fire alarm control panel

Plastic or metal housing, with or without surge arrester
Safe disconnection of the PV generator even in an emergency
Arc-free switching thanks to modern switching technology

Switches back on automatically after a power failure
In this case, we equipped an industrial building with a 1 MW roof system (128 strings) with generator disconnection and overvoltage protection. The QFire BIG switch boxes also include T2 surge arresters. A T1+T2 combined arrester would also be possible here. Each of these BIG switch boxes switches up to 16 strings.
Standard-Set Feuerwehrschalter für PV Anlagen
The modular, expandable set consists of a control box and a switch box and is suitable for smaller PV systems, for example in the private sector. Here, too, all lines from the disconnection box on the roof are galvanically isolated from the PV generator in the event of switching. This means that all DC cables in the building are de-energized.
