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.

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. On 4/5/2016 12:01 AM, Jason Wilson wrote: A few guys swear by these....

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.
