Default How many DC amps is too much

Here are some actual examples of cruising boats and how they managed
their DC power grid.


Add to your list our 28' mostly-weekender with an icebox and mostly LED
lighting. Twin group 31s (soon to be upgraded) charged by a 12 watt
solar cell.

Total fuel usage in about 120 days away from the dock and a couple of
thousand miles: about 15 gallons, as the solar cell supplies almost all
our needs. We motor primarily to move, rarely to charge, and we're
rarely in a hurry.

But we consume mass quantities of ice, about a 10# block of ice every
couple of days during a Chesapeake summer. Cubes go faster, but their
primary purpose is to cool my Admiral's drinks.

Would love to have a fridge, Kollmann is definitely in the running, but
we can buy quite a few years' supply of ice for the upfront cost and
backside power requirements.
