PV Fireman’s Switch

A house is on fi re. A fi re-fi ghting appliance approaches. The fi re fi ghters climb out, see a solar installation - and can do very little. The fi re services can frequently do little else than rescue persons and animals and prevent neighbouring buildings from catching fi re. The reason being that PV installations generate voltages up to 1000 V, which are still generated even after the power inverter is switched off. The Eaton fi reman's switch SOL30-SAFETY provides the solution, which disconnects the cable from the solar panels to the power inverters facilitating fi re fi ghting without an electrical hazard.
