Inverter over heating
Why did my inverter overheat and shut down the A/C while I was driving and had the generator on?

How do you know it was the inverter that did it? Did you loose 12V power? It's very unlikely that the AC has any connection to the inverter. Normally, the power for the AC would come directly from the main panel, which would have been fed from the generator. The only way the inverter comes into play is if it's also your converter, providing 12V to the batteries. The AC control unit probably needs 12V to work.

Inverter over heating
Your inverter should be protected by a transfer switch. The transfer switch allows only one 120v source, it this case it should be the generator. The inverter should also have been off so that you would not have to rely on the transfer switch. Transfer switches can fail. Your inverter has fuse protection so check them. Some inverters have a built in transfer switch it may have failed. Best thing is to turn the netter off.
The roof AC has no connections to your 12v system and operates independently. Transfer switches operate on the 120 side. The inverter could have been on but if the transfer switch is working the 120v switch is open when the generator is running, the inverter power goes nowhere.

The roof A/C needs 12V for the thermostat to run.

There are a few cc models that have front ac that runs on inverter power...could be others.
It could be the inverter supplies the low current to part of the ac that involves the control system.
But not enough information.
Get a volt meter and start normal troubleshooting

Is it difficult and or expensive to have an inverter removed? Maybe the previous owner installed it himself and did not do it correctly
