Tripp Lite makes dual conversion units with SNMP and external battery connector
all the way down to 750 VA. Dual conversion used to be prohibitively expensive
but prices have come down. APC has some units with high battery voltages like
192V, I assume that improves efficiency. Lots of advances since the old
Smart-UPS days.

I've had two of these running in the NOC for about two years. TRIPP LITE
SMART3000RMXL2U. Just using the internal batteries. They have a blue (48v)
external connector too. Not even on-line/dual-conversion. The AVR seems to
handle our crappy utility power just fine. Sensitivity set to medium for our
generator also works fine. I think we got them on promo w/ management card from
Provantage for like $900 at the time. Can't say there's anything I really hate
about them, other than one management card came with the newer firmware that
has the stupid java web GUI and all of the SNMP data of interest returns *1000
(40% load shows 400, etc), just an annoyance though. I can probably downgrade
that one, but that's like # 176 on my list of shit.

The drawback is no snmp monitoring, but that could be overcome. You add the
battery combination to suit your environment 12vdc bank.

I don't know about other's experience but tripplite seems to make a better
product across the board.

Yeah. At scale it is necessary to be able to buy the same model (or very
close) for consistent deployment and maintenance. Same battery trays, same
batteries, same management interface. That is why I'm specifically only looking
at Tripplite and APC.
After doing some more research it appears there are at least a half dozen
reputable vendors. As more enterprise type customers move their server stuff to
the cloud (err, butt?) a lot of used UPS end up going to electronics recycling
places.

Of course i am not a dealer but i have an unused 2U Eaton. I think it
is 1500 but i would have to check. Sounds like you need more than one.

Because I don't want to buy a bunch of cheap and used, for example
SUA1500RM2U UPS, and discover their charge controller or inverter are messed
up. Or it's had a battery swell and leak all over insides.
something like this, plus $25 100BaseTX IP management card:
