Can you run a generator while power is off...
Powering your room & critical appliances such as the fridge/freezer?
sunroom, solar batteries.. SILs should be able to managed of two panel and maybe two battery.
UPS power supplies don't have the juice unless you want to buy one that costs the same as a small house
situation sucks man good luck
Can't you simply isolate the power to the main, effectively isolating your supply to the rest of the world?Yeah I don't think a UPS is feasible like you said. A home made solar charged battery backup is probably the cheapest solution like you said. Something to run a bigger inverter for decent amount of time.
Stupid thing is I produce my own power I have solar at my house but for safety reasons for what they call the islanding effect the inverter is shut down when mains power is lost. To stop the grid still being live when they disconnect the feed I guess.
