On Exit Only, we had 90 amp
Balmar Alternators on each of our engines, and we had xantrex three stage regulation on each
alternator.
The rate limiting step of our
charging cycle was not the size of our alternators. It was the size of our
battery banks. The acceptance rate of our
batteries was such that they could not take full
alternator output for more than fifteen minutes before being regulated downward.
The only way we could have higher and longer output from our alternators without frying our
batteries would have been to add more batteries to the
battery bank.
That's one of the reasons that I went to
wind generators. In the tradewinds, we had a continuous output from the
wind generators at a rate that the batteries could accept without overcharging.
