Noise and generators
Battery bank is just under 600AH. Alternator is rated 160A cold,
but 147A hot which is the actual useful output. I've seen it put out as much as 120A, but that was on purpose to test it out. I don't normally let the batteries get low enough to require such high currents. Normally charge using the genset to power a 110A shorepower charger.

I have a 100 Amp alternator, but it hardly ever does more than 84 Amps into a 425 AH bank. "Doug Dotson" wrote in message ... All I can cite is the fact that I have run a 160 amp alternator on a single belt for about 4 years. No slip, no squeel, and full output when needed. No problems with bearings and still on the original belt, although I have a couple of spare belts due to the heavier stress expected. Very happy so far. I would use a dual belt unit if my space would allow it.

I've never heard of anyone recommending 100+ amps without dual belts. I used to run a 120 amp Balmar on one of my old sailboats with a single belt. Frankly it left a lot to be desired even at 50 to 60 amps - lots of squealing and chewed up belts. It would never get even remotely close to 100 amps, even for short periods. The belt slip was just too much for it. |
