For those that have the inverter and the 110 volt outlet in your truck: Grab your flashlight, run out to your truck, and look in the 110 volt outlet and check if you can find any copper inside that would make a connection to the grounded plug you would plug in. I purchased the FL3Z-19A487-B Ford part from a supplier. Mine does not have any way a plug would make any contact with the ground plug. If you can see a copper connection point in yours, then I must have a defective one. Nothing inside the one I have. OR maybe Ford is pulling a fast one and not installing a ground in that outlet.
When I was going thru electrical/electronics courses in college they had a saying to help one remember what wire go's where. "Black to brass to save your ***" in other words ground.
Brass is less expensive than copper and works just as good which is why it's used on every electrical outlet ground in your house and (truck if so equipped).

Take a look and see how many connections are on the back. If it's a grounded socket, there would be three wires connected. If only two wires, no ground.

Just checked my '19 for ya. No ground terminal connection.
That said, what would be the purpose? There would need to be a separate grounding source than the metal on the frame, etc. So, connecting the "earth ground" in the receptacle to the frame would go to the same place as all of the grounds elsewhere in the truck, the frame. If you wanted to be super fancy, I suppose you could put a modified version of a surge suppressor in that circuit somewhere. I could see that if you were running an antenna that was likely to get hit by lightning or something that was attached to a 110v device. But really, if there is a short, there are a couple of fuses/failsafes that are going to trip before that would.
So the inverter is grounded to the chassis, which means the ac plugs are too. What they don't have are isolated earth grounds. Not the same thing.
One thing to note: due to the fact that these to things share a chassis ground (12vdc and 120vac) is that you have to be mindful to never use a device that is plugged into both, or bad stuff happens lol. For example, if you are running a laptop connected to the OBD port for tuning/forscan, do NOT plug that laptop's charger into the 120vac at the same time. Outside of that, you're fine.

No Ground In Outlet
