I ordered from Amazon the Dometic Compressor Motor Hard Start Kit, model# 3311883.000 for $53.65. I'm still waiting for it to come in. Amazon estimates arriving June 22. Hopefully this will fix my problem with the B&S, so I won't have to spend $300.00 for the EasyStart.

Once running the a/c only requires about 15-16A so you would have about 9-10 A capacity left on a 3Kw for other things. But the problem is that the a/c compressor cycles on an off every few minutes so you can't plan on having that available. After a few minutes that battery charger load drops off a lot though so that would probably be Ok (but not with B&S apparently). The Easystart solves these problems and isn't THAT expensive so I just went that route. Everything works better and there is much less load on the genny.

Great info here all. I wasn't aware that the AC needed that much starting current! Alos, funny enough I was looking at the B&S gen sets this morning, although I was looking at the 6.5k version.
Question in line with this thread topic. If you have a 3k generator AND you get the AC cranking how much capacity is left on the generator to run other appliances, lights, etc, and will your onboard battery be able to charge? I am looking at a gen set to charge my batteries primarily, but if the temps rise or we are camping without tree cover the AC would be great to run in the evening or during my kiddos nap time.

It might or might not, reports vary.. This depends on multiple factors, including ambient temp, how long since the last a/c cycle, refrigerant charge, altitude, phase of the moon, throw of the dice, etc. IOW, don't count on it. If you want to be sure, get an Easystart or a larger genny.

Hmmm....BS from B&S.
Many years ago I bought the smallest Generac inverter generator, rated at 800 watts IIRC. It would barely run a 100 watt light bulb. Junk it was.

I find that the new Honda 2200 does run the AC with no problem. No soft start installed.

That is exactly the response I would have expected. They have their protection circuitry set at their max rating. Probably they have to to protect undersized FETs in their inverter section. So, they meet their published specs but not a smidge higher. I guess its another example of getting what you pay for (or not getting what you don't pay for).
If you're close the Dometic starter might get you over the top. But of course it might not, sometimes those starters are designed to help the compressor motor get started at the expense of even higher line load. Good luck and let us know how it turns out.

I'm sorry they did not provide a viable solution or admit that their generator does not work for the purpose intended.

Briggs and Stratton finally got back to me. They said that because the test that I did with the hot water heater and microwave, that I posted above, proves that the surge circuitry is working in the generator. Therefore, they insisted it was the Dometic air conditioner. I'm going to try the capacitor that Dometic sells and see if I can install it myself. I just can't afford th Easystart right now.

GC,
Please report what you find from B&S. |
