GM specs say the alternator on the Express 4500 cutaway chassis is 145 amps. does it matter in the above case?
Probably not as you are only going to charge the house batteries for an hour.
Stock GM 145 amp alternator... 10 lbs maybe.
Where is the cooling fan?
LEECE NEVILLE 220 amp alternator... closer to 30 lbs.
Even with #2/0 wires, a 200 amp solenoid, and 30 lbs of alternator I do not use this system to charge my house batteries for much more than an hour. I limit this time by charging my house batteries using the generator and two 100 amp charges in parallel before traveling... I have AGM batteries so they can take this high a charge amps.
I doubt the GM alternator above at high amps for more than an hour will last very long.
