Took a bit to digest that. So in general an earth ground on an off grid application will mainly provide dissipation of static electricity. Most of the safety features in electrical systems are for low impedance shorts and they will function regardless if there is an earth ground.
When a system is massive as in the average grid there are several liabilities or negatives aspects that require an earth ground to mitigate, but none seem to carry over to off grid. It does seem that all of the cons do carry over. Earth grounding does setup half of the circuit (N/G) in a relatively large area that can have some benefit, but an equal drawback. If anything or a person completes the circuit, current will flow through it or them. I understand that the earth has a high impedance and that most likely the current would be low.
I’m not saying that everyone should run out and pull their earth grounding. It is much better to do what is specified by the manufacturers and electrical codes. I do believe that the off grid applications should be separately evaluated based on its specific needs and modern methods developed.
