@AZ Off-Gridder any news?

Finally working on it now. Earth rod in the ground connected to the Generators frame ground. Using a 3 prong cord again. Trips GCFI again…. I’m gonna try to call MPP or Watts247

You'll probably have better luck with Ian, at watts247.

Does it trip immediately or is there some delay?
If there is delay, is it random or constant?

It’s every single time. There seems a small delay. Yes. But I’ve tried lots and it always trips….. unless I remove the ground prong then it doesn’t trip, but it only charges intermittently then so it’s not a solution. Charges for a few seconds on and off. One time I got it to charge for 12 minutes straight. That’s with ground plug removed

Is the delay constant or random?
Assuming its constant it means you have a 100% reproducible issue.
For a test, I suggest you open the unit and remove the neutral bonding screw.
See if that makes the gfci trip stop happening.
If it does we have determined that your problem is 2 n/g bonds.

 

[timselectric]

I believe that the ground fault detection, in the inverter. Is putting a small intermittent current, on the grounding conductor. And, this is tripping the generator GFCI.
Ian, probably knows for sure.

When you say neutral bonding screw you mean disconnect the white neutral wire from the unit? Correct? For AC input

No.
There is a screw inside the unit that defeats the neutral/ground bond.
I think @FilterGuy has a picture that identifies that screw.
If not I think I can hunt down a video that shows it.

No
It's a screw inside the inverter, on the main board.
Just be aware that you could void your warranty, if you open it up.

Inside inside, like actually opening up the unit? Not just the connection panel? I’m not doing that sorry I can’t risk that. Not unless advised by MPP reps

[timselectric]

This is with the screw removed.

 

[AZ Off-Gridder]

Ok. So after seeing that MPP told him it was ok I might change my mind. I guess I’ll give it a try….

 

[John Frum]

Ok. So after seeing that MPP told him it was ok I might change my mind. But why do I need to do this?

Because I think you have 2 n/g bonds and I'm trying to prove that.
This is just for a test.

 

[timselectric]

Removing the screw, would be the same as Removing the ground prong, from the cord.
Actually , I wouldn't worry about the removed ground prong. As long as it is only ever plugged into a GFCI receptacle.

Oh…. Well then it’s not going to fix anything as I stated when ground prong was removed it didn’t totally solve it. Yes I get constant 120v input uninterrupted and no GCFI trip. But the charging function is not constant. It comes and goes I can get a video. Batteries are low enough it should be charging

 

[John Frum]

If the removing the bonding screw fixes the GFCI trip then I would suggest...

Bond neutral/ground in the service entrance panel downstream from the all_in_one
Remove the bond from your generator
Remove the bond from the all_in_one
That way you have one bond whether the generator is attached or not.

Is it possible that the unit is flipping to inverter mode and that is why the batteries stop charging?
If the generator is not too loud you might here the bypass relay click coinciding the the charger stopping.

Inverter is off in these scenarios
