Detached garages would save lots of money and I’m sure lives too.I've followed a few people that went off-grid with lithium ion and the common principle seems to be to setup the inverters, charge controllers, batteries and backup generator in there own seperate building some distance from the house. Keeping all the "fire prone" equipment away from the house in case of fire. Much like some do with wood boilers.
I guess it also protects the expensive power equipment in the event of a house fire.
