I totally get that most off-grid jobs won’t be inspected, however isn’t it still a good idea for components to carry a UL listing in the event of a fire? It seems like an easy thing for a fire investigator/insurance company to pick out, even if it was not the origin of the fire. That’s been a (perhaps self made) deterrent for me over the years. Any thoughts?
