I really am out of ideas.
But, I won't stop thinking about it.

Whatever you did, that's what you planned.
All of the devices have to get synced before you can trust their readings. No one tells you that. Just one of the fun trap bear traps waiting for the newbies and those of us with short term memories.

I also have the same batteries. Different inverter.
I'm still puzzled by the generator shutting down even if the batteries won't accept a charge.
I would definitely do a reset. Take all but 1 battery offline and work with only 1 battery at a time to eliminate as much as possible. Double/triple check polarity and connections.
Failing all of that, I'd try bonding the generator. It's big enough it should run charging 1 battery or stay at idle if the batteries aren't accepting a charge from the MPP.

Same here.
And not familiar with mpp.
But, it shares similar internals as my Growatt.
I just can't put my finger on the problem.

My 2 cents is that it's tied to your BMS activating or already being activated and that you would do yourself a favor by getting them charged up before you try other other things.

Neither would I.
Unless the battery is shutting down the inverter and something about the inverter shutting down is tripping the generator GFCI.
MPP Solar, GFCI AC input
Hey guys, I recently purchased a MPP Solar 1kw box for fun. The AC input is currently tripping the GFCI breaker. The seller is saying I should short the neutral wire as the ground is already bridged internally. I am guessing the board controls the hot only. What do you guys think of the...

Battery Charger tripping GFCI
I just completed an upgrade to a lithium battery on my travel trailer. As part of the upgrade I abandoned the original charger that was part of the WFCO 8735 power center and replaced with a Progressive Dynamics 45 amp lithium charger. Everything worked great when I powered the new charger...

The all_in_one should be in bypass/charging mode, the inverter should not be active.

The inverter is not active in all previous scenarios

Great link I’m glad I’m not alone in this fight other people are struggling with this issue to seems like there is some strange ideas on that link with some possible safety concerns I’m not too sure if I should try them??? Like pulling the neutral stud out of the plug?MPP Solar, GFCI AC input

Yes, I know.
I'm just running scenarios in my head, as to what could be causing this issue.
Was that you I saw at San tan solar for their event on Saturday :D ???

I have the same panels, and same battery as you.
I'm leaning towards the inverter doesn't like the generator.

UPDATE: It “Appears” to be working!!! Took some advise from other post that was linked above. Grabbed my vise grips and ripped off the ground post on the AC in cord where it plugs into Generator. It now works. Provides power to the MPP unit and then charged batteries. GCFI is not tripping because it can’t. Don’t worry generator had separate 15a breaker still and all in one unit has many safety features too. Yay. Screw GCFI oulets. Jk

So, the problem is in the inverter. I'm guessing that the AC bus neutral and the DC buss negative, are connected internally. And somehow, this is sending a small current back through the ground. Or possibly the GFCI protection circuit, in the inverter. Is doing it.UPDATE: It “Appears” to be working!!! Took some advise from other post that was linked above.

Yes I checked this with my multimeter set on the highest setting and it’s barely readable but it’s there. Confirmed
Harmless??
