ArcBox in Action: Turning potential risks into safer outcomes for solar installations.
Recently a UK solar installer was called to a new-build property in Warwickshire after the homeowner reported that their solar PV system had stopped working.
Upon investigation, a severely damaged DC connector was discovered in the loft. Thankfully, the connector was protected by an . The resulting arc fault destroyed the centre of the connector, but successfully contained the event, preventing ignition of nearby combustible materials, including roof timbers and membrane.
What could have escalated into a serious roof fire was resolved with the replacement of the damaged connector and installation of a new , with no fire damage to the property.
