batteries in place of generator

[Wilhelmus Schreurs]

Ryan:
1500 amp alternator?? are you sure.
That would be huge, how would that fit inside the engine compartment?

You won't have 3600 watts available. Your existing alternator is

probably ~150 amps give or take and you're using a good portion of

that to run coach systems. So to be safe, your "extra" capacity is

only another 150 amps. Further, a 300 amp alternator does not

necessarily put out 300 amps, at engine idle speeds it might only put

out 180, perhaps less.



Someone has done this - set their coach up to run one A/C unit off

their inverter while cruising. I want to say they used a 1,500 amp

alternator to ensure enough power. I recall it was very expensive, in

the two thousand dollar range. Perhaps someone who knows more about

this will chime in.



At the end of the day, Dorn, to do this "right" I suspect you're going

to have more money invested than if you'd just bought a brand new

generator or had your own repaired/rebuilt.
