It does show in the manual that it can be changed over to a floating neutral. I currently have my generator ground bonded through the neutral bus in the panel.

I really think it's going to run your AC unit without a problem along with normal lighting, your refrigerator and freezer, tv. radio ect.

Are you using propane or gasoline?

The only thing is you should really undo the N-G bond at the generator, when hooking it to your house using an interlock. If you leave the generator bonded the equipment grounding conductor running to your generator from the panel will be a parallel neutral path.

I have a large propane tank that is hooked up to my gas logs. I do not use them, and I would like to use propane since it is not being utilized for my logs.

Yeah, I'd use propane too. You can store a lot of it and never have to worry about it going bad, or getting contaminated. And being dual fuel you can always burn gasoline if things get real bad and you have to resort to siphoning gas out of cars

Not always. Once in a blue moon more like it. Otherwise they have been hacked or ruined somehow if you can even find one.

Yeah but if you need it one of those old units are worth looking for. My buddy down the street at the junkyard got in a fight with PPL He had an old lister diesel genset that looked rough. He ran that thing almost continuously for 2 years only stopping it to change oil and filters. Darn thing never missed a beat.

You need to factor in the SEER rating of the unit to come up with any type of useful watt/ton calculation. According to the nameplate in your photo your unit draws 10.4 amps at 200 volts. At 240 volts it will draw even less. I don't think that you even need a 10kw generator.

Most premises single phase wiring I know is 240 volts using both a & b phases and or 120 with neutral so you won’t have 200 volts as an option

Delta power source systems with their high leg can give you 208 volts but not many residence wiring have this.

The breaker for rotor lock startup current would probably have to be time delayed if generator can handle brief inrush current

And there is overload protection if over 1 horsepower needed in addition to breaker

I ran a delta on my house for years, it was originally 277/480, changed the taps to delta, and just capped the high leg. Muffler rusted off the top, and filled the motor and turbo with water, so finally retired it.
A friend of mine does cell tower generators, he takes out a lot of them that are still good, most are single phase due to the rural locations.

208/120 Y is pretty common supply system for commercial, retail, light industrial, institutional, larger multi family dwellings and similar.
