So last Friday we went and looked at a 1999 240 Sundancer. Needs some work, but a nice boat overall. Anyway, it has a 6,000BTU Marine Air brand air conditioner with reverse cycle heat. Never saw that in any other 240's I've come across, but a *great* bonus for my wife. It worked fine under shore power.
We were wondering if this could operate while away from a dock using batteries and an inverter? I looked at some specs on the Marine Air website and they show that it puts out 6,000 BTU @ 115VAC with Full Load Amps to cool @ 7.0amps and Full load amps to heat @7.7amps.
I've been reading some topcis here today talking about amp-hours, reserve capacities, power, inverters, etc. and it seems that these numbers are reasonable values to run off of batteries for a period of time (though I have not done any calculations, just off the top of my head).
Can it run off batteries? Also, in reading about alternators, they seem to be rated in terms of say '60amp' alternator. Is this output amps @ 12VDC? I assume the higher the alternator output, the quicker time to recharge a battery...or not use the battery at all (running engine while AC is on).
Just looking for options. My wife was quite disappointed when she found out it could not be used while away from the dock, as our plans were to find a quiet spot and drop the hook on summer weekends... (which are hot and humid here on the Chesapeake).
Thanks,
Tom
