WE REALLY NEED TO HAVE SOME CONVERTER SPECIFIC SEMINARS.

Anyway, as a general comment, on our coach the inverters have internal pancake fans. The air flow to and from the inverters is ducted.

But I think as an added source of protection we have a pair of external fans that we can manually control via a switch so it has been our practice when using the coach that we turn these fans on and allow them to run continuously.

When the bus is in the garage I have those external fans off, but I will load up the inverters and just listen for the inverter fans to kick in to make sure they are also working.

There is a ton of little things to think about on these coaches and I don't know if any of us has figured it all out yet.
