Spread the love

So, you need a generator to run 2 RV air conditioners with ease? Well, we’ve got a couple of recommendations you might like.

But first, what size of generator do you need? You would need a 5,500 watts generator. I know this because mine run both AC’s and the microwave at the same time.

From experience, most and 5Kw or larger are able to run both 15k AC’s – by starting one and letting it tun for 5-10 seconds so the generator can stabilize, then start the other.

Remember, the Non inverter type generators are usually louder (and cheaper) than the inverter type. If anyone is anywhere near you with the loud generator running, you are bound to get complaints.
