These are going to be old maybe 10+ years old, and electronics doesn’t live forever. If nothing else, capacitors dry up. I have some 1400 RM XL units still running and they haven’t blown up yet, but at some point we can’t rely on scavenged 20th century equipment to run our networks.
It should also be noted these do not have temperature compensated charging and vintage APC equipment is known for overcharging batteries anyway.

We get some good deals on them. New sites or anything we can replace and do DC (24vdc) we'll use Meanwell AD-155B (IIRC) and DR40. From this point forward we'll probably be deploying Netonix switches. If you need sync on the Ethernet ports you'll have to go with Packetflux.

You mention inverter so I’m thinking you want an AC system? Also, is this going in a controlled environment like a NOC, or will it be in an outdoor temperature environment? And what is your budget? Sounds like you are finding $1,000 too expensive? If you are looking for an AC UPS that you attach your own battery bank to, that is spec’d for outdoor temps, and that has all the features built in, look at Alpha FXM series. Crossover Distribution can get you quotes. FXM650 would meet your power requirements, but I’d look at FXM1100 as long as you’re OK with a 48V battery string.
