High capacity alternators
I have a question along these lines. I have a 56hp Yanmar with the stock Hitachi alternator (single 1/2" belt). I have a large (880ah) AGM bank + AGM starter, a wind generator (LVM Aerogen 6), and a 12v generator (Panda 4kW). I was thinking of upgrading my alternator, not so much because I need more output but so I could externally regulate it (I have a Link 2000R). However, when I looked closely at the Hitachi it is an 80amp (cold I assume) alternator, not the 55amp version. Since it seems to work so well (5 years old, happy as a clam and only one belt change needed the whole time), maybe I only need to have its internal regulation converted to external capable? Or, since I have such a large bank, is it really pointless to externally regulate it anyway on a sailboat? To give you an idea of how much the alternator is used, the engine has 150 hours in 5 years of sailing. Any comments would be great--Thanks.
