The good news about buying a new unit, is new batteries. Any donated unit would have old or no batteries, you'd have to buy new ones for use. Typically gel-cell batteries are tens of dollars each plus tens of dollars shipping,
My APC 1500va 2u unit, I just buy new batteries at $20/ea, 4 total. Used units are everywhere and near free. One popped last year and off-gassed so I just unplugged the battery sled and haven't bothered replacing them yet. I got the unit cheap somewhere. A set of batteries lasts 4 years I'd guess. I used to have a 36kva unit. The batteries would have cost $6000 to replace when it hit the end of the line. That system was impressive but a beast. 300 amps, 3 phase 208 out.
