Again, I realize this is for my diesels, and gassers are a whole different animal, but it seems wild that they could drive a 7KW alternator.
We settled on 9KW alternators. These are still about 180 amps, but they are 48 volts. While it sounds cool to say 9KW, the reality is I expect they will more often be outputting about 4KW given our typical cruise at about 1750 RPM. This would give the alternators about 3500RPM which is around 100 amps according to their power curve.
We're in the yard starting March 17. The estimated time for all of the work we are having done is about 3 weeks.
