I am not technical. I admit all of the detailed advice and counsel I've been getting from this thread just wasn't processing in my head..... until yesterday. Then, with a POP and a flash, it all made sense. (!How does that happen?)
Posted here is this latest, final picture of corrections done to my inverter wiring.... thanks to you guys. Think I got it right.
If anyone else now sees and understands this (simple) wiring issue better, well that's what it's all about.
