Ok let’s play out some scenarios.

When you lose power, is your truck so happen to be fully charged?
Maybe, maybe not.

What if you need to use the truck while it’s supplying power to the house?

So let’s say you want to charge your EV with your 7kw Generator. Those are typically peak ratings. It can probably sustain around 5Kw. That means it would take a solid 24 hrs to recharge 100kwh battery. And probably 25 gallons of fuel.

You now have have to store 25 gallons of fuel. And keep it rotated. Yet another chore. Propane is better, but now you need about 40 gallons for one charge. And a bigger generator because they are less efficient.

The amount of solar you get in mid winter, even on sunny days is a fraction of what you get in spring, summer and fall. Above 1/5th. Which is when you most need it for a power outage.

Solar straight to EV battery in DC is barely worth the trouble with net metering. At max, you’ll save 25%. But in practice you’ll be lucky to save 5%. Because you have to have good weather, excess production, plugged in at the perfect time and need an empty EV to charge. Now if you never drive any where savings go up. But the truck is an expensive battery.

Generally you want to keep an EV charged. You don’t leave it empty so it can consume excess solar you MIGHT get.

Permanent batteries make sense in the right situations. Not with Net Metering.

If you want power security then get a permanent propane generator. With a large tank.

The best use of batteries is with off peak rates. Charge battery at night (off peak) and use it during peak. This will use up the life of the battery. Do you want to use up charge cycles on your shiny new truck to save 25% of electric bill? Do the math.

You have to run the numbers WITH the situation your in. If you don’t know what net metering is don’t spend a dime until you do.

Friend of mine just installed solar. Without net metering. Total waste of money. And she had wicked cheap electricity to begin with. Solar is not free. Neither are batteries. Nor are efficiencies of move kwh from one place to another free.

Only good thing power out of ford truck is good for is camping with your 60” wide screen TV.
