EG4 6000xp AC coupling. How to wire a manual transfer switch

[California Sunshine]

I have my EG4 6000xp up and running and I am loving it. Just north of LA and with fires blazing they are shutting off power left and right. We are good for 36 hours or so but, I would love to use my existing Enphase grid tide solar and the 6000XP AC coupling function to keep my micro inverters awake to recharge my 280-ah battery. Looking at the picture below it is unclear to me how it should be wired. In my Enphase combiner box, the solar comes into the breaker then down the bus bar then out to the main service panel. I know I need to put the transfer switch after the breakers and between the main panel. the question I have is, in the picture below, would the solar in the combiner box be the generator and the 6000xp be the subpanel? Basically, I don't understand how the transfer switch works. The one I have stated the top position is Line, middle is Load and bottom is Line.

Thank you in advance. I am trying this on a different thread to get more attention as I think this is a simple question. Where does the incoming solar, out going to Main Panel and Gen Port of 6000xp get wired.

Solar is the sub panel, and generator is the 6000xp. This would allow you to move the solar from the main panel to the 6000xp.
