Just finished reading paper by @FilterGuy: Grounding Made simpler - Part4. Good thing I did as I was planning to run three of 2GA multiple ground connections to a negative bus bar from three different chassis 5/16 bolts, instead of a single 4/0 connection from the neg bus bar to chassis which had to be further away. So I will be changing that to a single 4/0 to van chassis. But I am still not entirely clear on couple points, would appreciate a clarification, please:
1. Is it acceptable to run additionally separate grounding wires from MPPTs/Invertor metal chassis to the closest direct grounding points, instead converging them on the single grounding bar? To me its simply matter of convenience/cost running shorter smaller size wires due to a location placement.
2. I got confused with a picture and wording as on this screenshot:
The way I read this - the chassis ground should not be there, yet the picture diag shows it connected with a current flow. Am I misreading this? Sorry, I am new at this, so want to get it right with understanding.
Thanks in advance.
