Best overview of UPS devices and applications I’ve seen:

ups batteries are supposed to be deep cycle, and if you are not testing for a decent level of discharge you are not catching battery degradation until you actually need it
The test procedure of a fancier ups is theoretically more than just draining, its checking the voltage over that time to guesstimate how the battery is reacting. They are supposed to cry and ask for battery replacement well before the batteries themselves are done, as a safety margin

Consumer grade generators (like the ones from big box stores) create horrifically dirty power, a lot of ups see the spiky wave form and decide to stay disconnected.

Thank you for the information everyone!
I keep hearing great things about Eatons, but they unfortunately cost more than my budget at this time. Based on this thread and research I’ve done elsewhere online, I’m leaning towards:
- CyberPower CP1500PFCLCD
- APC BR1500MS2
Overall, the CyberPower seems slightly better: higher surge suppression (1445J vs 1080J), faster typical transfer time (4ms vs 8ms), more outlets (6 battery/surge + 6 surge protected vs 5 + 5), slightly lighter (11.29kg vs 12.5 kg). Also the CyberPower has the battery type listed right on the webpage (12V 9A SLA), so it should make replacing easier as there are a lot of places selling those online. Anyone have any advice on which to choose?
@Mellowlynx and @starshipeleven Thank you so much for mentioning this and explaining the process! It makes sense to do this, but I hadn’t thought of it nor seen it mentioned yet. This sounds like something that could save my a** at some point
Thank you for the info!
I’m guessing the Bash script pings your Proxmox server?
How do you determine whether the internet is up or down? Ping some site online?
My rack-UPS is a Dell-badged APC. APC is good quality!
