I am considering a home battery backup generator system instead of a fossil fuel generator? Can say the 6000x with a home integration kit be tied to my main panel with an auto transfer switch?
You can do this but you will need to have the AC inverter of the Yeti running at all times. You will need to check to make sure the inverter is on every 30 hours or so. The AC inverter on any of our large power stations shut off after 30 hours or so. If the inverter is off, you will need to turn it on again.
