… i’m looking more towards information about what kind of components go into the electrical system and the ways the sub-systems interact.
In a nut shell you need over current protection in case of a short circuit. You may need protection against electric shock hazards that could kill you if the voltage is high enough.
If you plan to run multiple devices you need to know something about load management unless this generator is far bigger than I think it is. If it is really big you need protection against electrical fires etc.
As for components you need meters, breakers, bus bars, switches and enclosures. Not knowing what part of the world you are in its hard to tell you what supplier is best bet for getting the right parts.
