Great overview! While I am a EE, I appreciate the research you did so you could cover the many non-obvious side effects of power system grounding.
I have a suggestion: There are many examples on the Internet of fusing (usually circuit breakers) both the positive and negative connections for a device. In particular, I see many examples of this on the wires between the solar panel(s) and the solar charge controller.
From your discussion of grounding, this would seem to be counter productive, as well as unnecessary.
Some clarification on this issue would be of value to many of us.
Wow, Such great information! Do not attempt to install a PV solar system, inverter, battery backup, etc., without reading all 4 parts.
I made it my mission today to thoroughly read, study and digest all four parts of Grounding Made Simpler. As the author recommends I began with Part one and took them in order comparing and studying the drawings along with the descriptions, further researching anything that wasn't sure about. It was so worth it. I doubt a video will ever be made that even comes close to the depths this written series has in clarifying this topic of electrical grounding. As I said, it took me a full day to read and digest this, but then I'm pretty thick. Still, I can only imagine the time it took FilterGuy to organize, write, illustrate, and publish these papers. Many, many thanks, it is such a gift for the those of us that need this knowledge.
To FilterGuy: I'm rebuilding a 29' Airstream travel trailer. An 800W PV array and a large 24V LiFePO4 battery bank are two of the big additions I'm incorporating. I had to tear the trailer all the way down to the frame so I'm also completely rewiring the trailer electrical, but I do plan on restoring the shore AC power to 120V and 30A, more seems unnecessary since I'm building it for boondocking and I'll have the hybrid inverter and a 24V battery bank with 560Ahs. I've been thinking a lot about, and searching for answers for the proper / safe way to ground everything. I'll feel so much more confidence now about making my solar charge controller and hybrid inverter selections. Admittedly, I'm a serious researcher and I take working with electricity very seriously. Up until now the majority of my experience has been basic residential split phase wiring, so, it's been necessary to learn a great deal considering PV and LiFePO4. DIY SPF, has been a godsend and your articles and papers are a perfect compliment to Will's videos and the great thread and Resourse shares by others! If you have any suggestions of information I should pursue I will gratefully receive it.
OUTSTANDING! It is only my firsst read of this. I need to really digest it in real world terms. That is going to take considerable time in my case. But now that it's all in one place when I can revisit the information and concepts I feel much better armed to keep my family safe from me. Thank ypu so much for the effort. (Shout out to @SmoothJoey for the first waning of the inticasies of this stuff and setting me on the search for this information. I still don't fathom it all. In fact, I am on the cusp of looking for formal online training that will drag me through it...)
