Solar powered server rack (mander.xyz)

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

I like your thoughts on runtime and recharge time.

That four hour limit really outs things into perspective for someone just starting out. Most people don't understand the constraints at first.

You can maybe stretch that 4 hours to several days. However you must get enough solar in 4 hours to provide more than 1 day of use. You will probably get to 6-8 hours of production from your panels, but the production is reduced in the off hours and there are almost always a few clouds reducing your output even at peak times so until proved otherwise just count on 4 hours. (prove can be several years worth of data, or careful local climate calculation possibly with various devices to handle the sun moving)
