A "transfer switch" is used to select between inverter and shore/generator power. This switch can be internal to the inverter or external depending on inverter model. I would think that the shore/generator feed to the transfer switch would be on a circuit breaker.
I suggest finding out what inverter you have and seeing if it has a built-in transfer switch or not. Also, a quick test would be to cycle all of your circuit breakers.
If you can locate the inputs to the transfer switch, that would be a good place to measure the voltage. If you have shore/generator power going into the switch but not coming out, the switch would be suspect as being bad provided all connections were good. If there is no input to the switch then you would look upstream at the breakers and wire connections.
The shore power and generator will have their own transfer switch to select between the two. If you get power from both sources to your other outlets then that transfer switch is good. Your actual outlet appears good because you get inverter power to it.
Hope this makes sense.
