It sounds like you have the circuits worked out. Do you have a particular question?
BTW, I wouldn't install the relay, choosing a manual switch, instead. Alternatively. using another breaker to power the converter. I just spent a few days and wore out my cuss-word load for a month, investigating a fuel pump relay in my Son's Subaru. Relays are another failure point, IMO. You may wish to have that convenience, no harm.
The converter will be on its own circuit, the relay is just for convenience. Main questions are the relay wiring and the possibility of an inverter bypass.
