@xyfdi@matrix The electrical network everywhere is so bad you need a UPS now (on the best grids you only have occasional power cuts for a few seconds or minutes, which a UPS handles fine).
Long term is looks like you'll really need either a generator injection plug and/or a non-grid tied large battery to have reasonable power reliability.
@xyfdi it's not bad, but it has gotten worse, the battery only lasted just over 2 and a half years, while the expected lifetime is 3-5 years
