I'm assembling a >300W UPS. I bought a Impinvt HT-12212 1.2kW Pure Sine Wave inverter, and tested it with a few external 12.8V 8Ah LiFePO4 batteries in parallel, and a 100W light bulb load.
The Impinvt works OK so far, even though it is intended for higher capacity batteries. Next, I plan to purchase a 100Ah LiFePO4 battery, which should power my 330 watts of office computers for about 3 hours. That will be fed from a line switch and emergency generator someday, and 3 hours should be enough time to debug a generator that "worked last year." I looked at Amazon's offerings and user reviews; many foolish buyers, many fraudulent sellers. I trust PLUG-folk more, especially the subset that keep local data centers running. So, who has stories of UPS battery victory and/or disaster to share? I prefer experiences to opinion; I've already created a surplus of contradictory opinions all by myself. Keith L. P.S.: yes, I have inline power monitors, P3 Kill-a-Watt and others. -- Keith Lofstrom [email protected]
