large -48VDC inverter recommendation [RE-wrenches]

[Kurt Albershardt]

<x-flowed>
They have a 10,000A DC plant and rivers of 750 MCM cable running about the place.

Timeframe is probably 2-3 months but I can check to make sure.  It could easily be setup as several smaller banks, maybe one per 19" or 23" bay.  What kind of power (complete system with DC & AC disconnects, etc.) could you get into a 7' bay?
