Why not just use a UPS (Uninterruptible Power Supply)?

jhickok Sep 21, 2021 View on HN

Out of curiosity, wouldn't a conventional consumer UPS take care of that?

Any proper server should be on some kind of UPS, no?

I'll add a #protip about UPS. Instead of getting Cyberpower or APC, I recently picked up a EcoFlow River 2 Pro[1] (portable power station). It has 768Wh capacity and 800W output and pass through charging. Crucially, it switches fast enough to not cause any outage to any of my gear (Ubiquiti, HP Proliant, Raspberry Pi, Synology). As a bonus, you also get the ability to do solar charging and USB power outlets.[1] <a href="https://us.ecoflow.com/products/river-2-pro-port

Are the servers on any sort of UPS to enable graceful shutdown if power goes out?

I believe you mean a cheap UPS. A cheap PSU is likely to last a very small fraction of a second in an outage.

Presumably a UPS is still using a switching power supply just with a battery backup.

How many people have their home wifi on a UPS?

Seems like it's worth considering UPSes for the controllers as well? Depends on the details of the power outages, and the draw of the controllers, and if the controllers handle the equipment being unpowered even though the controller is.

Why not use a ups for the battery?
