You are correct, it is for the engine block heater. It is a high amperage draw so I don't believe it is powered by the inverter, but I have never checked the outlet with a meter when I had the inverter on.
I know it is powered by generator and the ac power cord when plugged in. I have used mine a few times on the present coach and also on our previous GS diesel.
In temps below 30 degrees, what I have done is plug it in for about an hour before we plan to start the engine. It starts up like it is summertime then and the Kitty Kat just purrs.
