Running Air Cond off Inverter

If I'm reading correctly?

Yes, you got it.

watch the Easy Start device install video showing the amperage draw reduction. Impressive. Will this pass ABYC muster?

How old is the 16500BTU air conditioner? If it has any age to it you might want to check out the new ones. They are more efficient with lower starting amps and running amps.

I believe it's a 2005 cruiseair.

Adding a soft start (actually, what you want is the "SmartStart") will make it even easier.

There are reports that the Honda EU2000i will handle a 16k BTU air conditioner without either device. See: https://www.expeditersonline.com/for...tioners.66305/.

But I think it's best not to try the limits of these things. The power boost inverter is valuable for a bunch of other stuff, so I would do that in any case. And the SmartStart has got to be a good idea.

Is the Smart start unit installed in the A/C only 30 amp service? In my case I also have a 16,000 BTU forward and a 7,000 BTU for aft cabin and head. Both units are serviced by a single water pump.

Would it be safe to say that after the start of the 16,000 BTU unit and has been running for a few minutes that the Smart Start Capacitor would recharge and ease the aft A/C unit on?

There is an additional 30 amp plug for the normal house 120 volt. We also have a Honda 200i along for emergencies and cloudy days when there is no solar energy "Harvest"

Be Well

But if batteries are being constantly charged it still rums them down?

I was not clear.

No, the generator should be enough to carry the running load and to slowly recharge the batteries. The batteries will only be impacted for a few seconds during starting, which is nothing.

We are looking into a 3000i Handi to handle our 16btu AC plus other needs. Does anyone have any experience with this Honda model?

Reason people use the 2000 is more than anything, weight and size.
The 3K is I’m sure really 3K and will start and run an average 16K btu AC without problem, but it’s big and heavy.
I used to have twin Honda 2000’s and ran them combined, but storage of the things, plus their weight etc. made me go to a small built in Diesel genset

[Mommasails]

Agree that weight and size are considerations. The Handi weighs73 lbs and measures 24”x 20”x 15. Where did you store your units?

Also the little inverter units, besides being more compact and easier to move around

1. produce much closer to Pure Sine Wave, needed by many load devices.

2. Some can be paralleled to double output

3. Are super **quiet**

Construction site type portable gennies may put out more watts, but man are they noisy! Really a completely different product category.

Thanks for the feedback. With forum comments and further research, we have decided on the tandem system for all the stated reasons.
