Although I'd probably just throw my UPS away and put in a power station these days.

I have a very popular CyberPower CP1500PFCLCD I bought back in 2019, that is now approaching 7 years on its original SLA batteries (still working though). I was debating upgrading the SLA's to LFP or just stick with a UPS capable power station. One nice about a True UPS like the the cyberpower is that its switchover time is ~4 ms, compared to my current EcoFlow Delta 2 at 30ms, and the Delta 3 at 10 - 15 ms. Both which are far faster than my Tesla Powerwall 2's at ~400 ms.
I had encountered a UPS issue when I upgraded my PC to a RTX 5090 where UPS would start tripping over 1000W, but I solved that by downgrading my 5090 back to a 5080, so my power draw now is back to 700-800W.

Dedicated UPS are nice if you need that ultra-fast response time for extremely sensitive gear but for a computer with a good quality PSU, anything under 20ms is fast enough, and any good power station should be able to hit 15 ms or faster for their UPS mode.
I know I got a River 3 Plus that has <10ms switchover, but the voltage regulation is horrible, it can be as low as 70v and as high as 140v before it switches over to battery. I was using it on a home theater setup (TV, speakers, desktop computer, Roku and network switch, like 180w when everything was on) and in brown outs, the PC would reboot.
I ended up keeping my old APC with a bad battery and plugged that into the wall, then the River 3 Plus is plugged into that, so the APC will try to switch to battery when voltage gets below 109v or above 130v (what I set it to), and since the battery is dead, it cuts power, and the River 3 switches over to battery. This has fixed the issue for me, but is not ideal. I also have a River 3 Plus on my network gear, but since all that does 120v to 12v, it does not seem to care.
Not sure if the Anker/Bluetti/Oupes models have the same issue.
Also most UPS dont run 24v, most are 12v. You need to at least know how many cells are in the pack, as well as their C rating before you can know its power output ability.
