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...)
