I do find thousands of 110v AC's, but no 12 or 24v AC's.

I looked on the web and I can see that Coleman makes up to a 27KBTU
12/120v rooftop AC for rv's but I couldn't find a source. Any
suggestions?



Somewhere near you is a motorhome/travel trailer superstore. They all have
them. Google search for "Coleman RV air conditioner" and find thousands.

Do you realize how many amps a 6000 btu air conditioner would require at
12 volts? Hey Larry, they don't just take heaters to the boat.

Yeah, but they're not smiling luggin' a 12V AC down the dock.

Hmm....My 8000 window unit in the computer room runs about 800 watts.....

800 watts divided by 14 volts (to be fairer) still equals a CONSTANT DRAIN
of over 57 amps!

Man, we're back trying to figure out where to stow these 3 ton submarine
cells, again, to run it all!....

Nope...A/C is NEVER gonna run off 12V!

"But you sold me a 4,000 watt inverter, didn't you?"......(c;

Hmm... 3 ton submarine cells. Too bad we couldn't
talk the manufacturers into making my 8500 lb keel
into one big lead acid battery ;-)

Wow...Rolls Batteries (Would you use anything else in a Duffy?!) lists 8D
batteries between $433 and $907 each on:
http://www.staabbattery.com/rolls_de...atteries.shtml
We'll need the biggest capacity superbattery as only the best will do.

$907 each times 16 batteries equals $14,512 if you replaced them TODAY.
With a 7 year warranty that's conspicuously missing from the warranty
explanation webpage I'm not sure how long the REPLACEMENT warranty actually
is, but from the look of the other batteries, a 72 month battery only
replaces for 18 months. Beyond that it is pro rated down to nothing at 72
months. Anyone had an old Rolls deep cycle like the 8D replaced by them?

If they last 3 years before the capacity starts limiting cruising range
uncomfortably, at today's awful inflation rate over the next 3 years of,
say, 15%, replacement's gonna cost you around $16,000 to 17,000 PLUS
INFLATION EVERY 3 years....or so...

Sure makes what the boatyard told you it was gonna cost to overhaul the old
3 cyl Yanmar look real cheap after 7000 hours, doesn't it?

And, curiously, the Yanmar doesn't eat itself just sitting at the dock like
lead-acid batteries do.

OUCH!

I do realize how many amps, but I have a DC generator and don't want to
run the thing on an inverter.
