Not a problem. Just back the Ford F150 Lightning up to the panel box and light the house up.
And then run an extension cord from the house to the Ford lightning and charge it the entire time!
I know you are joking, but here is our situation. We live in an area near the foothills where the power goes out frequently during any type of windstorm. Our power was out yesterday for ten hours. Sometimes it is out for days at a time. The neighbors and us all have generators so the problem has minimal impact on our routines.
Most of us run our generators using natural gas which these days in our area costs about a quarter of what running them using gasoline does. We have our generator fully metered. We use approximately the same amount of electricity when the power is out that we do when it is working.
Even though an F-150 has a large battery it is still no equal to a dedicated generator especially when the generator is powered by natural gas. If we suggested an F-150 to one of our neighbors as an alternative to their generator... they would laugh at us.
