So, we had seen some issues with flickering lights when tying DC grounds onto the PE Bus of the XP.What did you find?

And where does it say in there not to use a common busbar of the AC grounded system? And yes, I also went to 690.41(A)(5).
Assume you need to add an EGC from batteries to the main panel ground bar. Still think it’s odd you can’t land the PV ground in the inverter. Just not making sense to me.
EGC to array and EGC to battery bank case.
Completely off-grid? Yes, this is totally viable and looks good to me.
I understand where you are coming from because it doesn't make sense to me either. I won't claim to know how every circuit on the inverter is drawn out, and why certain things work the way they do, but I know through hours of troubleshooting and consulting with the R&D team, that moving it has resolved that flicker issue for a lot of customers.Assume you need to add an EGC from batteries to the main panel ground bar.

Yes, Forgot about EGC from battery cabinet...Assume you need to add an EGC from batteries to the main panel ground bar. Still think it’s odd you can’t land the PV ground in the inverter. Just not making sense to me.
Yes, completely off-the-grid for cabin.Completely off-grid? Yes, this is totally viable and looks good to me.
I have a 6000xp setup with 2 eg4 batteries to go off grid charging the Tesla. It work great for 2 weeks but when I updated the 6000xp it gave me the 2 red flashing light in the Tesla charger which I think indicate no NG bond but I did have the settings 26 which NG bond enable. Still try to get it figure out what’s going on. anybody have this problem?I do not have experience with the tesla charger but I do know it has circuitry the checks for the NG bond. As far as I know it should work with your set up.
what about on-grid?Can I say this is TRUE:
For all those people that run the 6000xp Off-Grid and use a Chargeverter, disable setting 26 and bond your neutrals and grounds in your (main) AC panel. The End.
Please verify so I can move on.
For on-grid, the NG bond should be in the Main Breaker Panel and the relay in the inverter should be disabled (Never create a bond).what about on-grid?
I have grid power backed by an unbonded gas generator through a 4 wire cord and plug to the main panel using a manual generator interlock kit. I want to replace it with a portable inverter. I bought a TP6048 that bonds the output when input ac is off. I think my choices are: 1. go inside the TP6048 and find a way to disconnect the bonding relay (and the warranty), 2. substitute a 6000xp set to no-bond, 3. move my priority circuits out to a new unbonded panel connected through a three conductor transfer switch and bond at the inverter (either one). Am I missing something.The reality is, even systems that do dynamic bonding well has to make assumptions about whether there is a bond on the AC in. I do not know of anything on the market that can handle AC-in without bonding sometimes and AC-in with bonding other times. It could be done with modern electronics that detect if a bond exists or not, but I am not aware of any current inverter product with that capability.
So true!!! The 6000XP has a design center of stationary installs. Trying to apply it to mobile is a little bit of a square peg and round hole situation.
I know this is an old thread but have a question:This is a really good explanation. Very detailed.
The only thing I would add is Grounding in general. No matter what scenario you are in Off Grid or Grid tied you always need a ground. I know being Grid tied you will have one usually but Off Grid we see so. many ungrounded systems and that is so scary because you can or will become the ground at one point.
So please always have a actual Ground no matter what.
Were you able to figure this out? I’m having the exact same issue.I have a 6000xp setup with 2 eg4 batteries to go off grid charging the Tesla.

Enabled setting 26 but the EVSE shows ground fault. Testing the continuity between the N and G on the 6000XP makes the tester chirp once and then nothing. This is without load. Seems like something is not enabling the bond.
Yes. Just tested it again. The EPS was off. Enabled setting 26. Turned EPS On and the continuity between N and PE is there for the first time I touch the contacts, the meter chirps but instantly stops. When I test continuity when the unit is plugged into the grid, it works as it should because the upstream panel is bonded.Is setting 26 enabled while in standby, with the EPS switch set to the "Off" position on the left side of the inverter?
