Interesting video explaining ground wiring.

Hmmmm
Now to think through how I incorporate that concept into my off grid.

Interesting that Japan is now adding grounds to their GFCI protected system.
Quoting: gcrank1 how I incorporate that concept into my off grid.
Wouldn't the basic AC wiring used in the US & Canada remain the same as if we were grid-tied? The exception could be with our service panel neutral-ground bond. That will depend on whether or not the inverter or generator has an internal bond.
In a small cabin system, it would be simple and inexpensive to run each circuit through a GFCI receptacle as the first device on each circuit or use GFCI breakers for everything.

SO, am I better to put my stubby GFCI cord at the gen or up next the cabin input after the long cord?

The GFCI at the generator will protect the line to and into the cabin, so in theory and practice I would think that is better.
Just to be sure you or any reader knows, a GFCI does not need a ground to work. It just compares hot and neutral current and breaks the circuit if an imbalance is sensed. And one can have multiple GFCI daisy chained in the same circuit. Not necessary but no harm.
