Yamaha Inverter Generator EF2000iS question

Good question. I have two Yamaha's that I run parallel to power our houseboat. Using it to charge our 6 batteries, run 2 RV fridges, an ice maker, bar sized fridge, chest freezer, and misc. appliances periodically during the day we can get 6 - 8 hours before refilling.

The generators kick out of eco mode when the battery charger is on (about 3-4 hours charge time in the morning). With your load, I think you will be out of eco mode anytime the AC is on.

So, that is a long way to say I don't think you will get through the night if you are running the AC continuously.

I went with the Yamaha because I got a great deal on the first one at a time I was not planning on running parallel. It has been great, but had I known I was going to use them this way I would likely have bought Honda just to get the extended run tank.
