6000xp neutral bonding ?

[8milimeter]

I have a mobile solar trailer (4kpanels / 6000xp / EG4 powerpro 14.5kw).
In order to use this system in an emergency situation to power a few items in my home, is it necessary to even run a neutral wire.
If I run L1,L2 and a ground wire, would'nt the bonding in the main panel take care of the neutral.
If I don't run a neutral wire, would I need to turn off bonding in the 6000xp.

NOTE: I can disconnect from Grid at exterior panel

Absolutely necessary.
You must run a neutral if you have any 120v loads.
Bonding provides the safety grounding system. And can only be in one place.
(At the main panel)

If you are tired into the main panel of your house you need to run a neutral and ground wire and turn off the bond in the trailer.

Another question.
The 6000xp produces 3000watts 25 amps per leg. I assume a 10ga wire would carry the load 220V.
If I draw 25 amps from each leg at 110V, what size should the neutral wire be.

10 AWG, the same size as the L1 and L2.

Drawing 25A from both legs means that neutral current will be 0A because they cancel out.
But you have to design for maximum imbalance, so 25A on L1 and 0A on L2 means that the neutral current will be 25A.

Always run 4 wires for split phase: L1 (black), L2 (red), Neutral (white), Ground (green or bare)

If using pass through, you may use more amps and larger wire.
