EG4 6000XP and Grid "Input" neutral

[Emeryj32]

I’m looking for the wiring diagram to connect to the grid as a pass through to my combiner box. Do I need a ground and neutral from the AC grid to the combiner box or just the red and black?

You always need all four wires at all times.

Thank you so much.

If I intend to exclusivly power a 240v load by the 6000xp, is it safe to only pull L1/L2/G wire from the main panel to the GRID side on 6000xp ( no neutral ), and in this case, should I disable the inverters N-G bond?
