PV Next Fireman Switch

PV Next Fireman Switch for safe remote shutdown

Building insurers and local fire services are increasingly demanding that rooftop photovoltaic systems switch off automatically in the event of a fire. This switch-off device must be placed when the string cables enter the building. Automatic switch-off occurs when firefighters switch off the building’s power supply. This allows firefighters 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.

In order to optimally meet the increasing demand, we keep standard versions of our PV products permanently available from stock.

How it works

Product Features

The new PV Next Fireman Switch combines strings in an extremely space-saving way 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 firefighters to work safely and fires can be extinguished more quickly. In contrast to other solutions, electricity is only consumed during the switching process. Whether for small or large systems, with 1 to 12 MPP – we offer the right solution for every inverter.
