Also this circuit shares a wall to the garage and I already tapped into it so I would have an additional 120 volt circuit out in the garage to use. Now all I have to do is install the inverter, add some fusing and back feed power on to that circuit.
I think the first part will work, but the second part will not. All 120 volt circuits go back to the panel and the meter, so you will backfeed no matter where you connect.

Here's another idea. Store the excess energy in hot water. Install an electric hot water heater in line before your existing hot water heater. Then run the electricity from the panel into the first hot water heater. 240 volt elements will work just fine on 120 volts, they just pull less power. This approach depends on the solar panels not producing enough power to boil the water, which should be the case here. Worst case, the relief valve pops.
The vacuum gauge plus wheel covers helped increase summer 2015 mileage to 38.5 MPG, while summer 2016 mileage was 38.6 MPG without the wheel covers. Drove 33,021 miles 2016-2018 at 35.00 MPG.
