re: So how many kW does a 2 ton ac use?

It’s a 15000kW starting and 12000kW running. If that helps. I’ll try to get that info to add to OP. Appreciate the answers!
OK, the 15,000 starting watts @230 volts brings the starting amps to 65 amps. If the locked rotor amps (LRA) on your condenser plate is less than 65 amps then the generator should be large enough to start and run the 2 ton unit, particularly if a hard or soft start capacitor is added to the condensing unit (easy and inexpensive) with likely sufficient amperage to run the other items you mentioned in your OP.
I’ll be interested to see what others think and say that have first hand experience with this, particularly after you post the LRA and RLA of your 2-ton Carrier.
P.S. should note if you run the 12,000 kw generator on natural gas or propane it won’t generate as much kw as if running on gasoline - so that will need to be accounted for as well. .

A 12 KW with 15 KW surge should be plenty enough to run a 2 ton central unit, fridge/freezer, and should have enough left over to run a good bit if not all of your lighting/ tv loads. Especially if you have LEDs. A hard start on the condenser would not be a bad idea to help with the startup surge.
Your problem is going to be feeding that thing. It will be very thirsty if it’s gas, especially if it’s a 3600 rpm unit. It will probably have an 18 to 20 hp motor, and burn close to 2 gallons an hour at rated load.
