Willie, One brand I know is the older 3kVA Powerware 9125 UPS that can be picked up for reasonable price "used - needs batteries" and run from your 120V pack. The Powerware uses 10x 12V batteries (120V string) so they should be able to work up to 150V DC or so. I have a 120V pack in my truck and I am working to get one of those inverters, so that I can access up to 3kW of 120V AC in case of emergency (or field testing).

Too high voltage, I guess. I guess I need something like a 100 vdc pack to make a 120vac motor happy? Can someone suggest a way to drop the pack voltage some? I guess (I'm doing a lot of guessing here) I should consider an inverter. Has anyone seen a 2-3kw inverter that accepts 140-160vdc input? Alternately, I guess I could use a 12vdc inverter, a big 12v battery and depend on my car's DC-DC to eventually recharge it. If my Belktronix DC-DC will do 300w, I guess I would need to use only a 30% duty cycle; use ~1kw only 1 hour out of 3. Comments? Suggestions? -- Willie, ONWARD!
