The iGen2200 is working great so far. It quickly started up in about 2 pulls. It's relatively quiet. I have only run it for about 1 hour so far. It is able to power my gas furnace(~800W, 15amp). I had an electrician connect an EZ Generator switch to my breaker/furnace. I did ground it since it has a floating neutral and the electrician thought it might help based on what he was seeing for the power coming out of the generator. I decided to use an 8ft 5/8 copper grounding rod. The neutral connection on the back of the generator is small. I'm not sure what gauge wire they are expecting us to use. Since I am in the mid-west, I opted to use the 5w30 full synthetic for the oil during the colder months. I bought Stabil to add to the fuel (87 no ethanol) to make that last longer.
We can run this for 24 hours with 2 gallons of fuel! If our electricity goes out we have the ability to run our fireplace and keep our house warm so pipes don’t freeze!
Purchased two of 2200’s for running parallel for home backup and alone for various applications. Easy to operate, very quiet, simple parallel cord set up too! My only complaint, and it’s minor, is no fuel gauge. Love them!
