Off grid house bonding sanity check

...

I thought of another analogy for this. If the generator is a valid place for the N-G bond then the solar array would also be a valid place. But this would be ridiculous. ...

Well, it's ridiculous in the first place because the PV array isn't going to have a neutral. Beyond that it's ridiculous practically, but not code wise in the context of this discussion.
 
Therein lies the problem. There is no switching at the OUTPUT of the inverter. The inverter calls for generator and then takes power from the generator into itself. It may pass generator power on to the loads but that is only incidental. The inverter does not switch BETWEEN itself and anything else. The inverter is always the "source".

This thread is about the place of the N-G bond, GES etc. on an off grid system. Some postulated that it maybe should be at the generator.

I thought of another analogy for this. If the generator is a valid place for the N-G bond then the solar array would also be a valid place. But this would be ridiculous. The generator, solar array, some water wheel, are all auxiliary sources that feed into the inverter (or battery system) but the inverter is the one thing that is always there, always running, always required.
Ah, so. Is the generator DC?

'Sno biggie; we go off on ridiculous tangents all the time. :D
 
Some are. Some are not. Why does it matter?
It matters because if it is DC the generator can cycle off and on without interrupting the inverter, but if it is AC unless there is a way to synch the generator with the inverter it won't match phase with it when it starts up. I am assuming that the generator won't run unless it is needed and unless there is a way to synch it, it seems to me that the generator has to be the master when it is running and there will be a glitch when it starts up and connects.

Please do not misunderstand me; I don't know the system and I am trying to learn about it.
 
If you bond at the generator or inverter your bonding in equipment that may need serving and or replacing, if you loose the one and have to ship it back to civilization for replacement you dont loose you G-N bond wile you run the other.
Also if you bond in the main panel its easy to find, and easier for an inter-system bond to your massive off grid HAM radio setup that we know you have in your off grid house.
