Generator Inlet and Interlock Kit for Pro Onboard 9.6kw

So, I’m trying to get a grasp on the Home Back Up Integration and just felt it’s being over complicated.

I have a Generator Interlock kit with a 50amp breaker hooked up with to a NEMA SS2-50P inlet box outside my garage. I use that to plug my 12,000 watt portable generator to run everything in my home including HVAC during a power outage. Note: AC condenser has a cold start kit to reduce starting amps.

In theory, couldn’t I just hook the Ford Lightning’s 240v bed port into my generator inlet using my existing generator cable to get 9.6kw of backup power? It’s on a 50amp breaker so it would max at 12kw, but I can get a smaller 40amp breaker instead to avoid damaging the truck and I wouldn’t run my HVAC on it since it’s starting amps are 45amps or 10.8kw.

Im just trying to avoid having to pay for the Home Integration Kit and the Pro charger since I ordered an XLT with SR battery.

Any thoughts on why this wouldn’t work?

It comes down to this. The truck has receptacles, and as such, it is considered a portable generator per OSHA. This means the receptacles will need to have the neutral bonded to the ground for short-circuit protection. The issue is if you open this bond (which you will want to do for home power), then when you use the truck as a portable generator, it would be unsafe as it needs to have the neutral and grounded bonded once again. In portable generators (gas-powered) there are plugs you can buy that have the ground and neutral tied together in the plug. This way, you can leave the neutral unbounded for home power and use the plug when using the generator for portable power. I have yet to see the drawings for the inverter in the Lightning but will have one here for use in the next month. Here is the OSHA guideline that explains the risks. OSHA generator safety
