Hi folks! Wasn't sure how many people are looking into generators to run their house and fish pumps but I just finished one including the A/C for a 2000 square foot house. This generator will even run the 4 ton A/C unit!
The trick for the A/C is to get a soft start. Not a hard start but a SOFT start. The difference is a soft start is not only easier on the compressor it really brings the load down to not only start but run the A/C so a generator can handle the power requirements. Hard starts just dont bring the wattage down enough for most generators.
I picked up the largest inverter generator I could find. Inverter generators have cleaner power and don't harm electronics that can be sensitive like pond pumps, refrigerators, computers, tvs, etc.
First thing is to put the soft start on the A/C itself and have the electrician or yourself measure the amps for start up and run time after the install. Mine went from needing 18 amps to needing 4-6 starting up and 9amps to run so a drastic improvement on power consumption.
Next to buy the materials needed.
Generator 1000 bucks
Soft Start: 350
Install Soft Start by electrician 140
30amp plug 51
30 amp 25 foot electrical cord to generator 75
Interlock kit for electrical panel 70
30 amp breaker for electrical panel 25
Installation of interlock kit and plug were free from a friend of mine but would probably be around 250
The interlock kit prevents you from making the mistake of connecting to the grid when there is a power outage which can put workers in danger. Basically its a giant switch to turn off the power from outside and allow the generator to take over.
Total: 1961
I can run two large pumps, a tv, computer, fridge, freezer, lights, fans AND A/C and the consumption was about 4500 watts.
hope this helps someone thinking about it
