MPP LV6548 AC Wiring Question

Is this method of AC wiring with a transfer switch that does not switch neutral (using a Reliance transfer switch) still best/okay to do? This image is from FilterGuy's grounding and bonding PDF. The only other question I have for it is what about the ground that runs from the transfer switch back to the main breaker box? Would it get left unattached since inverter 1 is grounded to the main box as well as the transfer switch anyways?
Per @Zwy you'll probably need to make up your own mind as to how to wire this. @FilterGuy 's version is fine, but if you go with that you'll need to take out one of the screws to eliminate an N-G bond in one of the boxes. I spent hours reading through this, rather raging at times, debate: https://diysolarforum.com/threads/signature-solar-eg4-6-5k-off-grid-inverter-6500ex-48.40478/ You'll probably need to do the same to understand the tradeoffs. On balance, I was convinced to go with Zwy's design. There's also 'uge debate on here about one or two grounding rods ... on balance, I was convinced to do a single ground through the Service ... all tradeoffs, and each situation will be different.

I appreciate the feedback. I will definitely go through that thread. For clarification though, you mention removing the N-G bond screws from one inverter. @FilterGuy diagram that I showed has the screws removed from both inverters. My main service panel already has a N-G bond, so with my limited knowledge, it makes sense to remove both screws to prevent a second bond.

The only time you would remove both bonding screws is if there is no bonded AC-in and you are placing an n-g bond on the output -OR- you are creating a 'common neutral' system by tieing the input and output neutral together.

Reports here on the forum and elsewhere indicate wiring for common neutral works for this class of dynamic-bonding inverters, but I have never seen comments or documents from the manufacturers that this a supported on these inverters. (Note: Many of the higher priced inverters *do* implement common neutral internally but they do NOT do dynamic bonding)

Okay. So it sounds like I will be doing it like your diagram in figure 6B (Common Neutral). In this example, can the transfer switch (Reliance 510) be grounded directly to the main panel still also?

@FilterGuy This diagram is showing both boxes with the screw removed, but in the text on the bottom right, it says to only unground one. Is this diagram correct?
