OK, it looks like I have one of two options to get this thing going.
Buy a phase converter so I can run the 3 phase motor on my single phase system. Found these:
Need A Variable Frequency Drive To Run Your 3 Phase Motor On Single Phase Power?

See relatively inexpensive.
Second is more of a question than an option. Since there is 3 phase coming into the breaker box, can I have an electrician install a 3 phase breaker box next to our single phase one? And then run the buffer off that?
Clearly if the first will work, it's the best option but am interested in opinions on the second.
