Even the big 30A fuses in the converter?

Is the battery disconnect (if so equipped) turned on?

Welcome to the forum.

For starters - make and model of the converter?
Did you recently replace the battery and maybe reversed the wires?
Do other AC circuits (air conditioner / microwave) work?
Do you have a digital voltmeter, even a cheap one?
