Our (a hijacker!) current problem is, we have been told the start-up draw on the server room A/C unit we want (this is a real one for real server rooms, not a portable) is 100 Amps. That doesn't seem like much, except the compressor runs on something like 408 VAC.
SO, such a generator would need to be about 45k Volt-Amps just for the room cooler start-up. Contractors are now investigating this a bit further... -- Richard D.
