I actually have one a 56KW I bought six months before we sold the old building to run a new disperser.
Reason we bought it was fire Marshall wanted the whole place rewired to hook up new disperser, so it was cheaper to spend $4800 on something I could sell when done, then spend 10,000-15,000 for a new fuse bock and wiring in the one section.
Forgot all about it, it worked great and is still under warranty if anyone wants it, that you know, I will cut a deal and ship for free. I also have the optional voltage box to protect against voltage variances.
Problem using these things is it would take a whole bunch of them to run our place.
Reason we are moving the three phase box is the under ground cable would be under the new addition, so we are moving the box to far side and the three phase pole has to be moved also as the build would end there and the pole must be 15 feet away by code.
All this should come in at $9,000-15,000 dollars as we are using copper wire and the wire alone will be about $5,000. JOY!
