If your battery bank is 24v, why not use a 24v generator?

Or, go back and think about post# 9.Yeah, 803 or bigger is where you will be. Just comes down to if you want to have a machine thats selectable phase, or if you will be able to tap legs for single phase as needed, without unevenly loading certain legs. If you can get away with running a machine at a time, versus multiple machines at once... I think you might do well with the 10kw class.
I am stripping what is left of my 500mcm and 1000mcm cable to save for when copper goes up in price. I used 300 feet to connect a 400kva gen set to the distillery next door. Used my pickup to pull the cable thru the conduit! It was fun laying out the cable by myself to get ready for the pull. I know your pain and frustration with big cables. I use 250 and 350 mcm welding cable for battery jumpers and it is so nice and flexible compared to building cable!Got to agree with this info. And its gotten so bad with copper prices, that the copper usage in the PF, (Photoelectric world) has gone to about 0% here in Germany. Aluminum, that's about all that's used now a days. We used to make fun of the East Germans for using mostly Aluminum, but the jokes on us. It takes a while to get used to be good at hooking up Aluminum cables, (I am not talking about small wires) but once you get the hang of it, I like it better. You have just never lived until you have run 300-400 meters of 240 mm (600 MCM) through a building and then hooked it up! Go to the gym for a work out? Not even close!
I buy only 3 phase equipment and power them with an American Rotary phase converter. I convert to single phse only if the 3 phase motor fails. The phase converter has to be a fair bit larger than the motor it supplies though.You are absolutely correct in that you can find some fantastic deals on high quality 3 phase power tools at auction. I have almost quit looking for single phase equipment for this reason. The vast majority of home owners don't have access to 3 phase power unless they install a converter.
