high power inverter

HI-I live in hurricane country and power outage is normal-I need a schematic for a high power inverter that I can feed with my 300 amp miller welder. The 240v sytem it has, is way to weak. I need 20k watt at 100 amp 240v service output
input from 55-90 v and 60-300 amps.

Re: high power inverter

Let us start with 2 questions:
will you be able to arrange for 25kW 50V-to 240V transformer?
and
is the output voltage in a form of square wave acceptable?
