Re: Yet another pointless insistence on "cloud"
"...a cloud-based service for remote monitoring and management, scheduling of battery replacement, etc."
Nope, no cloud needed or even "smart" anything. I've personally assembled a 1200 array lug-to-lug UPS and the only software used was in the Fluke meters. Test a sample and rotate them out after X months regardless, then test the old/replaced batteries. You'll know immediately when the voltage drop occurs at the control, all this without anything smart. At home, you can do this with a USB charging adapter plugged in with a ATTiny attached to a buzzer. I don't go that far, but if you want smart you can achieve this many ways without a cloud or vendor supplied anything, just build it up as needed.
Another field being sold the "smarter is better" crap is in the main control, so just because the UPS is fine, that doesn't mean your control thinks so. IMO all of this should be completely analog and while I'm no longer part of any of this, I've been hearing scary stories about fire systems. Apparently there's a few fire marshals out there doing too much work thanks to things being so "smart" (you're lucky if the fire marshal doesn't shut you down after 2 times, 3 times and you're on forced vacation).
FWIW, with the smart/nic controllers on UPS's you can have access to things like N.U.T., but personally while I've read the readings, I never really have done anything with those readings as I simply replace a home UPS battery ever 18-24 months. So it's a neat feature, just not that amazing.
