This makes a ton of sense and I can't believe I didn't think of this before. I think your question just saved me a few thousand dollars because I already have a manual transfer switch I hook up to my gas generator for the intermittent power outages. I don't need it to be automatic and my 6.5kW generator is more than enough to get me through with choices of what I want to run when the power is out. The rear 7.2kW should be enough to do what I want to do with a 240v plug.
