I'm looking to build a 48v system on my barge. Currently all DC loads are 24 volt. I don't expect that alternator charging will be a primary source of power (I have a 7000w generator plus planning for solar). The boat currently has separate 24v alternators for house and starter batteries. I've been quoted a price of around £1700 for a custom built 48v 100A alternator and wakespeed controller.
One alternative would be to run the alternator directly into a 24v - 240v inverter, then that into the 240v 48v main inverter, but it seems clunky.
The other thing I'm wondering about is using multiple 24v -> 48v victron DC DC charge controllers. The biggest one they make only outputs 8.5 amp at 48v, however for the price of the new alternator and a wakespeed controller, I could buy quite a few charge controllers and run the in parallel. In practice I would not try to make the equivalent, but at least it's a way to get some charge out of the engine. Is this something that's possible? Can you run multiple charge controllers in parallel on one alternator, to feed one battery?
Any thoughts welcomed.
