Do you still need a UPS if you have one of those household (Powerwall style) battery packs? Also Apple switched mode power supplies are pretty well built. But then again there's horror stories like https://www.reddit.com/r/applehelp/comments/1maegvb/i_burned... | ||

My understanding is that home batteries are not UPSes, they don't go through the battery. They have a switch between power company, solar, or battery. I think that means would be exposed to surge from power company. You can install a whole house surge protector. Those go in the panel and would protect from different sources. | ||

Yes. The power walls are like cheap UPS topology. You could still get whacked with a transient from the grid before the ATS decides to island the house. | ||
