Anyone know the current status of the neutral bond issue with the EG4 3000?

I just received a EG4 3000 and the discussion about where to neutral bond is all over the map. SO as of February 2024 when using the grid to charge the batteries, AKA the AC in is plugged into the wall, do I neutral bond at my installed load center or does the plug in the wall provide the electric to charge my batteries also provide the neutral bond back to my main breaker panel?!

Tell me about your system.
Is it a single 3000?
Is it being installed in a mobile system or is it hard-wired/stationary (It sounds like it is not hard-wired).

It is a single 3000. It will be attached to one battery for the foreseeable future and I will run a plug so the AC in can be plugged into a nearby wall socket. I recognize that I can't charge with much current from a wall socket. I DO have a load center attached to the AC out with a few breakers in it and run to a few outlets in 2 different directions.
My question is, if it is always plugged into the wall would I separate the grounds and neutrals at the box? Is that how these work?
It is not mobile. When I finish installing it, it will be stationary. Perhaps I will run a dedicated 30 amp circuit to it in the future, but for now, it will be plugged into a wall socket.

The system you describe will work fine if neutral and ground are kept separate on the output. (The down stram breaker box should be set up as a sub panel with Neutral and ground kept separate)

If the system is portable, mounted in RV with provisions to connect to grid if needed, what is best way to handle the ground?

These are a common neutral?
 
Thanks for the information and great thread! I am running two 3000's (off grid) currently in single phase (looking to set up in split phase) and wanted to ask how this needs to be configured relative to this neutral/ground bond? The neutral and ground are separated in the breaker box, but believe both inverters have this neutral/ground bond - I have not changed anything. My thought is that only one inverter should have this bond, but any guidance is appreciated.

I would imagine that if they are in split phase and only one inverter had the bond, the other line would be lacking it's bond. So theoretically, either both inverters would need the bond or neither bonded and one bond in the panel.

But I don't know how the manual says to do split phase bonding for them. It should describe it for sure.

The 3000ehv has a dynamic bond so you should not have to worry about disabling or enabling it. However, I would recommend having the neutral-ground bond at the main panel if possible.

Hi Jared, can you please help me understand something. I want to achieve the opposite and get this inverter back to a simple off-grid system that can be run without an electrical panel (the Will Prowse idea). Scenario: single inverter, 1 battery, no grid , no electrical panel. I understand that in order for the dynamic bond to work, I need to re-attach 1 screw on the board.

But I also saw this EG 4 video , where your collegue Brayden explains that there is a seperate software for "mobile application" .. I cannot seem to find this software for the 3000ehv. My question is , do I need to reflash this inverter for the software to work correctly in my scenario or is there no change to the software? I would greatly appreciate your feedback on this.

The 3000 does not have software to turn off the dynamic bonding.
