Recently purchased a 2000 Ciera 2855. My boat is equipped with A/C and i would like to be able to use it while not on shore power. Without installing a permanent generator. How much power does the A/C unit need? What size generator is needed? I have 3 CO detectors in different areas of the cabin. The generator will be strapped on the swim platform when we take it with us.

I think the Honda EU2000 will be what you need.RMSLLC wrote:

Do a search, this has been talked about over and over again.
The challenge is STARTING the AC. As they get older, they take more power to start. A 1k could RUN the AC, but not start it. A 2k MIGHT or might now start it. My Honda 2k had trouble starting the 7k BTU unit in my 2455, and the Kipport 2k definitely could not start it.

I believe you can double up with two EU200 generators and run your air conditioner. Still cheaper than a marine unit and you can use just one for light loads and two for the air conditioner, maybe even use the microwave at the same time. This would be lighter than a 4kw and you could have one on each side of the boarding platform so they would balance the boat

Depends on what size the AC unit is as well. The 2855 factory installed AC was 12,000 BTU, it would be close with the Honda 2000. I actually downsized the AC unit on my 2858 from 16,000 BTU to to a 9000 BTU to enable it to run off the Honda 2000. The Honda would have run the 16, it just wouldn't start it as the start current is up around 35 amps, 16 amps run current. With the 9000 the honda has plenty of start capacity for the compressor, running under 10 amps run current.RMSLLC wrote:

Most of the 2855 boaters, here in Central Florida, are using the Honda 2000.

+1 on the startup....I had this exact problem last summer, what I figured out was to turn everything else off at breaker panel except the ac, turn the Eco idle off at gen, turn temp down so low on ac that I knew ac would never cycle off. The Honda would start the ac and after a few minutes I could turn breakers back on to fridge and outlets....I left battery charger off.
Ac and Honda worked like a champ the rest of the weekend.

We have a Kipor 2000 and the boat has a 12k unit. Nno problems at all running the ac with it

someone said up.....to use 2 generators together...how that would work? (sorry to hijack the thread)....I found a used A/C but is 16.000 but my little 2K will not push foward but I have another 1K that maybe combined will do the trick....

The Honda EU generators can be paralleled to double their output. The units have to be identical for these feature to work and their "Eco" mode must be disabled. (Both generators have to run at full rpm's.)Alexirocz28 wrote:

So I don't think you can just add another random unit to what you have now to increase your output.

Quick hijack... how do you like the Kipor? Have you seen the Honda in action in order to compare the two?bayliner2859 wrote:

My EU2000 runs the whole boat. Ac,battery charger and Frig.Start with eco off and run a minute than turn on other breakers.

Just generallly speaking there are 2 numbers to consider when you are working with a generator, the load rating and the surge rating. It's that surge that will get you with bigger appliances like friges and AC units. Anything with a compressor of any kind will always have a very high surge for that short couple of seconds until it stabilizes. Once it's running it drops right back down and all is well. Most common appliances have approximate surge and run ratings you can look up so you have an idea of what they "really" draw. You have to watch it with big "kick on " items when anything else is running as you can easily exceed the rating when it starts up and make big expensive things burn out in the blink of an eye. You really gotta watch that with the small generators much more closely than bigger ones with a large spread between the run and surge ratings.
They don't talk much about that stuff in sales but you tend to learn those things when you survive for days in the winter with no power during an ice storm. Different circumstance with boats but the same rules apply. One thing for sure, I;ll take a small honda over a big box store Coleman cheapo twice the size.
