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 (yes, I own it and have PTO and sell back) and the 6000XP AC coupling function to keep my micro inverters awake to recharge my 280-ah battery and power a subpanel critical load. 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. Should the main service panel got to top line, Enphase solar incoming to middle load and bottom line go to EG4 6000xp gen port configurated to AC coupling? If so will the gen port take that incoming solar and charge my battery and or run the load carried by the 6000xp inverter (sub panel)?
Is there a wire diagram that I am missing to ensure things go correctly?
I got the answer on another forum. Top line goes to EG4 gen port, middle goes to solar output from Enphase combiner, and bottom goes to main service panel.
Next question is do I always leave the gen port in ac coupling enabled mode?
