If you heard a "bang" or pop, and/or smelled smoke, then it's probably toast and not worth trying to fix unless you or someone you know have enough skills to find out what blew. It's worth opening it though to see if there's some internal fuse or circuit breaker or something that tripped.
That is the problem !
I know enough about inverters to know that the most common failure is the output MOSFETs. At least 4 of them, maybe 12 or 16. $2 - $6 each. Maybe a diode, even cheaper. If the transformer(s) did not fry
(unlikely), then the rest of the parts are relatively cheap.
If you don't want to spend the money on an inverter with an automatic transfer switch, wire the output of the inverter to an external outlet near your RV power cord. The power cord is now your non-automatic transfer switch ! Either shore power or power from the inverter but not both !
