Hah yeah, I've seen some European websites with units that could probably work down here in Peru. We're 220v and 60Hz here, but I think most of Europe is 230v and 50Hz.
I did spend a few hours yesterday looking into the various units on the market. I really wasn't too impressed by any of them. I'd say 90% of them don't use lifepo4's, and the ones that do seemed overpriced based on their specs. I guess you're just paying for convenience, because I could get roughly the same thing down here with a couple roof-mount panels, a 48v Growatt 3-in-1 unit, and a 48v 50ah 2.4kwh lifepo4.
I guess they're just marketed as being "portable" so that's why they justify a higher price.
