The PV Next Fireman Switch explained simply

Rooftop photovoltaic systems require a disconnection device near the PV modules that is connected to the power supply in the house. This allows the fire brigade to carry out extinguishing work in an emergency without being unnecessarily endangered. When the power supply is restored, the PV Next Fireman Switch automatically reconnects the PV strings.

How it works

Product Features

The new PV Next Fireman Switch combines strings extremely space-saving and can reliably disconnect them in the event of a fire. The current flow from the photovoltaic modules is interrupted as soon as the power supply inside or outside the house is switched off. This enables the fire brigade to work safely and fires can be extinguished more quickly. In contrast to other solutions, electricity is only consumed during the switching process.

  • Simple and space-saving installation
  • Energy-saving, fully autonomous switching on and off
  • Efficient combination of strings with cable savings of up to 50 %
  • Standard variants available from stock, further variants available within 6 weeks
  • Variants with integrated overvoltage protection available
