Your right an electrical
horse power is exactly 746 watts not a 1000
don't get confused about Kilowatts and KVA
KVA is resistive load only
Air Cons are inductive
18000btu / 240volt /7.05 amps on heating
and 5.75 cooling
have a nice day
Yes, include a loss factor. 15-20% is a good ball park number. In my practical experience, a horsepower is not 754 watts, but something closer to 1000 watts when all is said and done.
"How do I intend to operate away from dock? As above, only for sleeping A/C (and I really only need the 16,000 BTU unit on, I don't need the 12,000 BTU unit on). If I could have both - GREAT! If not, I'll live with it.
As mentioned, water pump would probably be the only other thing along with a few fans and a few LED lights. Battery charger and GPS/VHF/Autopilot would all be off during generator use."
I think I can honestly state that in the future you will not reduce the electrical
demand load, but instead add to it. You don't list an anchor
light. Nor any refrigeration
loads. What about a stereo or tv? Do you plan to reharge your phone
? All of these items call for the larger generator
. We have a coffee maker, vacuum, etc. that all get used regularly, and require electricity. I have a corded drill, orbital sander, buffer, etc. Do an electrical load plan.
I have seen a lot of the portable Hondas while cruising, typically sitting on someone's foredeck laboring away to recharge batteries. In this use they see a couple hours a day of runtime. They are
noisy, contrary to other reports, use gasoline which is dangerous as well as expensive, and being air-cooled (and built to a price
point) have a much shorter anticipated life span - compared to a slow turning diesel
genset. [The Panda is, I believe, a high speed diesel engine
, not one of the 1800 rpm
, long lasting units].
As a matter of fact, I think most cruisers use these small units in conjunction with solar
A built-in diesel genset would likely add value to your boat
. The portables, no.
Why have to manage two fuel
types? Gasoline is often more difficult to obtain than diesel. You cannot safely store it belowdecks. It goes bad faster than diesel, especially if ethanol is added.
A diesel genset can be programmed to operate automatically. Could that be useful to you?
Take a second look at a built-in system. Maybe second hand? And the boat
shows are coming up soon.
Just my 2 cents.[/QUOTE]
