Well this was finally resolved last Friday with the electrician on site, a Tesla Senior Product Engineer and the Smart Charge America Project Manager on the phone.
We went through the details of the install once again. The install was correct.
The tesla engineer mentioned that the amp measurement and the amp overload error codes are created by the truck. Ha!
I had measured the amps on the house side and used an o-scope to chase transient spikes. Nothing there.
We then conducted a test where I measured the amps on the connection between the gateway and the wall charger. Viola! a 106 A spike. On the house line steady 6 A.
The Gateway was shorting out the truck when going off grid! Now it was crystal clear that the gateway had a fault which we suspected day one. It was swapped and has been working ever since. This now also explains why we had a strong humming noise during the fail-over that was mentioned to Tesla since the beginning.
The performance of Tesla support was the worst ever after purchasing 5 of their vehicles new since 2014. Deny, Deflect, Defend, Diffuse since February and me spending considerable of time to diagnose myself every step of the path. They believed that the house was overloading the gateway. They refused to listen and process my measurements that were carefully documented with pictures and videos.
Smart Charge America did their very best including pushing sending replacement hardware to the electrician. This avoided having yet another visit.
The Tesla engineer indicated they will modify their SOP. Case closed. Thank You for everyone's help, especially Jared!
