If you have a "failed" inverter it might be worth talking to the folks that built it to see if boards are slide in type and thus can be replaced by someone with no particular knowledge of an inverter.
I do know from installing by-pass switches in my coach that inverters need cooling, and one of the things I am going to very much aware of in the future is the cooling fan operation with the hopes that if my fan fails to function, I will notice that and get the fan replaced before it costs me repairs to my inverter. On my coach the converter provided a secondary pair of fans powered by the inverter output to insure constant airflow through the inverter so it is critical and likely extends the life of the inverter.
