Ups and power cut backup / off grid

Verdigris

Oh, and broadband router but probably only portable devices to make use of it.

Solarchaser

Lux ac inverters have eps, but its up to you to isolate from the grid.
In the first outage in 15 years I wired it up and it ran the house for a few hours, about a month ago, but I had to switch off the main house power to keep those working on the lines safe.

I'd imagine it would allow the solar inverters power up, but I haven't tested that tbh
