Hi,
OK. What you are saying is that you have a functionally obsolescent electric
service that needs to be upgraded to a 200 amp service to better handle
todays electric needs. I suggest that you contact your electric company and
find out how much this upgrade will cost you.

As the person that started this thread, I can certainly explain why *I*
don't buy one.

The equipment I want to run will need about 45A per phase.  If I had
an 85% efficient converter, I'd need an 80A 240V circuit.  The entire service

 entrance to my house is only 100A, and I use more than
20A of that for
lighting alone, not to mention the microwave oven, audio and video gear,
and modern computers.

Normal US homes are not wired for big old computers and their peripherals.
