Of course, we can only run one AC when using the 4000 Onen generator. It has worked quite well. Comparing the cost of trading with the cost of upgrading amps, it proved better to upgrade what we have. Nice having the increased power for other reasons too.

If you haven’t already, reading the following thread may be of interest to you if you ever want to power both air conditioners from 4,000-Watt Onan. I don’t know your specifics, but with other major electrical items off, the 4,000 Onan should be able to power two modern and efficient air conditioners provided start-up current is limited. I also don’t know how your Onan is wired to upgraded 50-Amp panel which could make a difference. Just a suggestion.
