In the Pacific NW:

Refrigeration: 60-90 ah/day
anchor light: 16 ah/day
inverter loads: 50 ah/day


That jibes very closely witn my experience in the North East. In the
south refrigeration takes a bit more, probably more like 120 A-H/day.

Same as mine, though with my big freezer I don't see 60 AH from the
fridge, its more like 70-110. Also, my inverter loads are lower
because I try to use as many 12V appliances as I can. In particular,
I found that the AC/DC TV uses a lot more power in AC mode. TV, DVD,
FM, cell phones, etc all run off DC. The computer is the only thing
that uses the inverter, and that only about an hour a day. Other AC
loads, like the occasional microwave and coffee grinder are only a
minute or so and don't add up to much. In fact, the big inverter is
left off almost all the time and only turned on for special needs.

But the totals aren't much different - around 120 to 170 a day, with
around 30-40 recovered with solar and the rest either engine run or
the small Honda gennie.
