Slipknot, I have no specific knowledge that is relevant to your question. But looking at the datasheet for what may be the model you purchased, I note this statement:
In any event, congratulations on the generator.

Superior harmonics and sine wave form produce less than 5% Total Harmonic Distortion for utility quality power. This allows confident operation of sensitive electronic equipment and micro-chip based appliances, such as variable speed HVAC systems.That doesn't strike me as particularly reassuring. Also, in addition to harmonic distortion I would have concerns about how free of electrical noise and RFI the Generac's output is, neither of those things being specified. I would also wonder about how economical doing what you propose would be.
In any event, congratulations on the generator.
