Generator Neutral-Ground Bond Question/Solutions, off-grid

[kampto]

I have a portable 240v generator that has a Neutral-Ground bond and I plan to use it with my 6000xp for back-up charging battery and as a stand alone portable. Place is Off grid, no Shore power. Gen is manually connected and started, no transfer switch. How does this set-up sound:
1. Disable the 6000xp internal Neutral-Ground bond setting. Put a Neutral ground bond jumper in my main panel instead. More reliable?
2. Keep the generator Neutral ground bond permanently intact for portable use in the field.
3. When plugged into the 6000xp, The 240v 4 prong SOOW power cord from generator use L1, L2, Neutral but do not connect the ground wire to avoid double neutral ground bonds with common grounds.

See any issues with this?

I would use option 2.
Doesn’t the EG4 open the N-G when external AC power is connected?

That is the default behavior of inverters that supply a N-G bond - de-bond when passing through source AC.

I would:

Disable EG4 N-G bond.
Put it in the load panel.
Get a non-stupid generator that doesn't supply a N-G bond (or figure out how to break it). There's a reason most generators don't provide a N-G bond... it makes them worthless for powering a house, where the N-G bond is typically in the panel.

So the question is when I do use it as a back up for house 6000xp system is it it simply enough to not connect ground wire from gen to 6000xp and keep the gen neutral bond?

I can disconnect the bond on the gen. But this Gen will be used in the field for welding and tools so maybe I would like to keep the bond. So the few times a year when I need it to run 240v to charge batterys via EG4 6000xp, can not connecting ground wire resolve the double neutral bond issue.

It's about the same as running it unbonded in the field.

LOL, I think we on the same page. Gen permanently bonded on itself, always. When using with 6000xp the SOOW cord connection will not have the ground connected to 6000xp.

And the N-G gets handled by the internal transfer switch anyways.

In my situation I’m offgrid.
I’m using a 6250W gen with the N-G intact. Current setup is that charging using an AIO is handling the N-G with the transfer switch - can’t remember but I believe the 1012LV’s disconnect their bond in the presence of 120VAC input. And I use the generator independently for the big tablesaw and welders.
Next ‘rendition’ is to replace the 2000W inverter with a 3000W I have; I will run the generator with a 6-50 cord through a 60A 4-wire 4-position 240VAC switch so that the shop subpanel can either be fed with the generator (120/240) or the inverter (120VAC one phase) using the switch to also switch the G/green so I can keep the generator bonded for portable use. Just need to not switch it with any motor loads.

Then I never have any unbonded situations, and during The Dark Months I can run the shop off the generator directly if needed.
