I guess I did miss the inverter. Most definitely your inverter could be bad. If it is indeed an inverter rather than a converter.
An inverter that has let all it's smoke out could be the problem. Try to disconnect the inverter and see if the breaker pops. The bad thing about an inverter is they are factory sealed and the smoke cannot be put back in. Alas you will have to buy a new one that is full of smoke.
