Welcome to the forums.
One of the 4 breakers is the mainline which is 30 amp and should located in the lower Left position. This breaker feeds power to the other three.
Next to it should be the GFI breaker which feeds power to the devices that are not working since it trips.
You know what the one on the right top is and the other one on the top should be for the Air Conditioner.
The GFI breaker could be bad. Also, if you recently replace the converter you might have a problem with the GFI tripping. There have been others with the same issue and have replaced the GFI with a standard breaker.
