running a/c on inverter

[Pete Masterson]

The '95 and later 'birds with the DD Series 60 only have one 300 amp alternator.

Are you sure that running your big generator is more efficient to run one a/c, from the standpoint of burning fuel to the output of the a/c?

With your engines you have two alternators, so each one would put out 50 percent only and then have 50 percent left over for other items.

My LXi is set up to run one AC off an inverter and the alternator, but
conventional wisdom is that you shouldn't do it. Steadystate current
draw from the alternator is 150Amps. I want to preserve my precious
alternator, so I always run the generator when I need my AC's.
Another point of view to consider the inefficiencies of the alternator
in generating DC and to add on to that the inefficiency of the inverter
to convert to AC to run the air conditioning. The generator is more
efficient at generating the needed AC.

I'm trying to figure out a way to run 1 of my A/C units on the inverters and alternator. I 
would think with the two 2500 watt inverters, and the 300amp alternator, this would be a 
doable venture. Can someone tell me if, and how to do this task?
