Hi Josh,
Just curious, what batteries do you have in your bank, and where are they
mounted?
Am I right to presume that having more charge capacity would result in shorter
battery life?
Just trying to size my eventual solar panel purchase.
Thanks! Bruce Whitmore

Much of your problem is a matter of battery capacity as much as a matter of
charging capacity. I have ~450 Ah of capacity on one bank, a 90 Amp alternator
that never reaches full load, and 200 watts of solar. Even without the solar I
was able to comfortably keep the the fridge running and the lights on when
cruising for ~2 weeks. The half hour to hour of engine operation to anchor or
moore in the evening and the same in the morning was always enough to keep the
batteries charged.
Keep in mind that the battery capacity should be at least 4x of the charge
capacity for flooded lead acid and at least 2x for AGM. So a 400 Ah or 200 Ah
respectively for a 100 amp alternator.

A question for your collective wisdom:
I am scoping out upgrading my stock 55A alternator to a 100A Balmar, and
related upgrades to the controls. I had a very productive discussion with Rod
Collins at Compass Marine (mainesail), and we worked out the details.
Unfortunately he's booked out through the spring, so this job will wait until
next winter.
So thinking then about keeping the batteries charged, and the fridge running on
our long summer cruise - where we may go for weeks without access to shore
power, I got wondering about using a portable generator to charge the batteries
- as an alternative to many hours of running the diesel. There are a couple of
Hondas that might do the trick 2000 Watt, weighing 47#, 1000 Watt weighing 29#.
Have any of you tried this? What could (would) go wrong if I plugged this
generator into my inverter, to charge the batteries?
