>>This drive wants balanced voltage and wants an unlimited supply of it now!<<
Ha ha ... yep. The 611 is a high performance drive system. For comparison sakes, lets compare the 611 drive system to a hot motorcycle engine that has an 11.5:1 compression ratio. You bought the motorcycle as it is a real screamer and drove it to the gas station and they were out of super premium 95 octane gas. So you filled the tank with 87 octane gasahol, and now it barely runs! :-( I used to work for Siemens and I had to interface periodically with the German engineers as we tried to apply their gear to situations in the US. I can almost hear the German Siemens Engineers screaming about your situation right now. It would go pretty much go like this: What the h_ll are you doing with that fine 611 drive system?... it needs clean 3 phase power.. no junk, NO JUNK! Single phase service... what is the problem? Buy a good generator powered by a fine Mercedes diesel engine and equipped with a good Bosch generator head and you will be all set. Cost? They would say you only pay for it once, buy the best. ;-) Of course they aren't trying to run a small business.... so I entirely understand your situation. :-) However, they would not! Oh well.
