Has anyone gotten their server rack to run off solar power.

I got the idea after seeing the Anker solix systems on sale at costco and thought what if I could get one of those to power my server rack and have a few rigid solar panels on the roof to charge the battery up during the day and run the server partially during the night off the battery, but switch over to grid power when it runs dry?

Curious if anyone has any experience with that, I'm not looking to do my whole house just my server rack for now, from my limited tracking of my rack it looks like it uses 8kwh a day so it seems possible. Searching online it looks like there are much cheaper battery options than anker

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.

Pure Sine Wave design provides extremely clean power

Why is this not on their own website?
