PV Next Fireman Switch for safe remote shutdown

Protecting PV installations against overvoltage and automatic shut off in case a fire

The new PV Next Fireman Switch combines strings in an extremely space-saving manner, protects against overvoltages and can reliably disconnect strings 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.
