If the battery doesn’t pass through grid power then I think you would use an automatic transfer switch that switches between mains and battery inverter depending on which is powered. I had dreams of offsetting my homelab power with solar + battery + inverter.

NeatoBuilds@mander.xyz 4 weeks agointeresting, I do have a UPS on my rack already so chaining it isnt an issue. everything is plugged into the UPS now so I was imagining just unplugging the UPS from the wall and into the anker box, then just figuring out how to add enough solar panels to power the rack but also charge the battery

The recommendation to not daisy-chain UPSs together is less about what makes for a cleaner setup and more about not damaging them.

My UPS at home just straight up won’t run off of another UPS unless it’s a perfect sinewave. Square wave REALLY makes it mad, and modified sinewave doesn’t work either. No matter what the UPS will refuse that power and only use its batteries.
I can’t find anything on their website about it being sinewave (pure or modified) so I’m going to assume it’s square wave. I’d imagine a high quality PSU found in a server will handle it, but it won’t be happy.
