Sounds good. So you need to find out how your inverter behaves, in regards to the N-G bond (within the Auto Transfer Switch function behavior of the inverter). I know on my MPP Solar LV6548 inverters, when the inverter is turned ON, the inverter closes a relay contact which joins the neutral and ground at that point (since it is the power source).
If you shut off the LV6548 inverter (put into bypass mode), then it releases that N-G bond there, and just passes the AC input wires separately, right through the unit (this is its ATS functionality) to the AC outputs...
So now if you feed that AC input with a generator, then it becomes the new power source, and so you need to make sure that the generator is N-G bonded (not all generators come N-G bonded, and is grounded using a ground rod.
So if the inverter is the primary power source, the generator would then be referred to as the 'separately derived power source'...
So suppose if the inverter type you have never breaks the N-G bond under any condition, then in that case a generator would not need to be grounded with a ground rod and no N-G bond needs to be made there (grounding it only through the cable conductor back to where the N-G bond device is).
Here is some more info:
As a general rule, a residential portable generator does not need to be grounded to the earth via a ground electrode or rod in any configuration unless it is supplying power to a house with a transfer switch that switches the neutral in the main panel. This makes the generator a separately...
