Are these UPS units going inside the racks? Would it not be better to do something in the power room with an inverter on the circuits that feed the racks, such as a large Outback unit with sufficient battery capacity? http://www.amazon.com/OutBack-Inverter-3600-Watts-Volt/dp/B002MWAAYU With one device acting as your UPS you'd have only one point of failure (that may be a plus or minus), only one set of batteries to worry about, and those inverters are very well made. They have 120v and 240v units. There are other brands you could use but my experience with various brands is that Outback is the best in their class.

I've had issues and experience with many types of UPSes, including HP (probably OEM'd from someone else), APC, EATON/Powerware, and Liebert/Emerson. I keep coming back to APC. Solid units, and are always slightly 'ahead' in technology. Sure, I've seen each model have failures and even faults (big boom style), but APC provides a solid product and supports their customers the best if you ask me. That being said, a very close second choice would be EATON/Powerware.

Does anyone use Eaton 9130 series UPS for anything? I'm curious how they've worked out for you.
I bought a 700VA model to give it a whirl versus the traditional APC since the Eaton is an online type with static bypass and also does some high efficiency thing where it normally stays on bypass, but the first thing it did on the bench was have the inverter/rectifier or bypass section catch on fire and destroy itself.
