For the price you would spend on buying the Honda new....you can get real close to a dedicated whole house unit with ATS.
Of course that depends on the size of the house.
Extension cords into houses means open windows or doors. Power typically goes out in bad weather.
FWIW I have a 6500W gas unit that will run both A/C units, and my electric water heater. YMMV.
If I can help let me know.
