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.

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.

Wow $300 for an EasyStart... the extra $300 would vault you from a 3k to a 6k+. I see your frustration now GC. Can't wait to hear if the motor hard start kit fixes the issue. Best of luck.

Yeah I'd be interested in the (cheaper) dometic kit if it does make the start up surge easier on the genset.
Please let us know how well it works, or not. |

Why the angst about the $300? Bigger isn’t necessarily better. I look at it this way: for a measly $300 I can run my a/c off my dinky 47 lb Honda 2k. In fact it has no noticeable startup surge, the Honda just loads up and runs, straight from ECO mode. To me and my lumbar vertebrae that’s a great value. I don’t begrudge a small company like Microair making a profit from their innovative solution. |

offgrid. You're right. If I knew then, what I know now, I would have bought a small generator and with the money saved, bought the EasyStart.

I think that's unfair to B&S. Their 2600 watt generator trips in a very few seconds if asked to deliver over 3000 watts, its peak rating. That another generator will struggle and run at under-voltage long enough to start the A/C should not be a valid expectation. Running an electric motor at low voltage will damage some, if not most. Since it performs as stated, we can only say it has no excess reserve and we need a larger generator.

With the EasyStart, my Generac iX2000 does not struggle to start the AC compressor. The B&S generator would probably be okay if an EasyStart were installed. However, it would not have been my expectation that it would have been needed.

Agreed. But for my application I would prefer to pay up for a bigger gen set so that I could fire up our water well, ToyoStove and a few lights if our power were to ever go out in the winter. Granted the bigger gennys come at the expense of added weight. I think the Honda 5k is over 150lbs.

Your pocket book may feel better, but a larger generator can be quite a bit heavier. I (personally) would not like having to lift a 150lb generator no matter how short the lift.
