Sounds complicated -

I would look at the option of sending the DC over that distance and putting
all the inverters next to the AC interconnection point.  In a smaller
application (SB1800) I chose 4 #10 DC wires (and isolated grounds)over a
2/0 pair with #6 ground tie that the AC run would have needed.  With
reasonable runs I prefer the inverter on the pole under the array, but with
wire prices through the roof I penciled it out and trenched the DC.

Sincerely,
