Welcome to the forum. I can't possibly explain what you want to know. Based on the things you have written I think you are in way over your head.
My suggestion is to spent a lot of time reading other posts on the tech section of the forum Also spend a lot of time digging around in your RV but without changing anything. Eventually you will absorb enough knowledge to be able to ask the necessary questions to accomplish your goals.
When asking questions be specific. Tell us what RV you have, what converter you have, what generator you have, etc. Give brands and model numbers.
