They don't want people leaving the switch on while the line is being repaired so that the workers get zapped by solar inverters that are powering it instead of the grid. Such systems exist, but I don't think they're common and they cost significantly more. It's easier for them to sell you a separate inverter that's not connected to the house wiring and therefore doesn't have to follow the regulations. > - Keep a bulb connected to outside to find out when electricity comes > back. > - Connect your batteries to a suitable inverter, and connect the > output to the inner side of the big house switch. > > Anyone having a solar independent installation, not connected to the > mains, does that. True, but here, and I think in many other countries, once the house wiring has a mains connection there are a whole lot of extra rules to follow. https://www.energymatters.com.au/renewable-news/plug-in-grid-connectsolar-inverters/ -- __ __ #_ < |\| |< _#
