How big is your generator?

5500 watt will be fine as long as your ac is window units. If you wish to run central ac,electric stove and water heater you will need a 15KW for starters.

You can get the electric company or an electrician to do an energy audit. You can turn everything on and check it while your AC is running on a hot August day, about 2 p.m. That is your peak demand. If you want no interruption in your usage - I would size the generator to 10 to 15% above peak demand (or just the next class up).

You can also, sort of, do it yourself by checking your meter and seeing how many KW you take from the electric company from about 1 pm to 5 pm on hot, July and August afternoons and divide by 4. That should be a good average high demand number, but I would still size the class above that.

I have a 4ton central air unit.

Got a 7month old and if a hurricane comes I want to make sure him and mama will be comfortable.

9 inches



Oh sorry. 6800 W

What does that do? Im wondering if my 9k can run my little 3 ton unit. Know it cant run my 4 ton unit.

It stores energy for when the ac kicks on. It helps to get the compressor going when it is first turned on. This is what the ac guy told me. When my ac units were new,the generator could kick them on with no problem. after a few years it would not and my ac guy put these on and it has worked fine since the install.

6500, I usually just run a medium sized window unit in the living room if I have too. Will run that, fridge and all the fans necessary to keep air moving.

5500 Watt. Wired directly into the house. Runs window AC, TVs, fans, fridge, freezer, lights. I turn on just about all the breakers and justs use what I need, when I need it.
