I appreciate the feedback and ideas, but it sounds to me that some of you are unfamiliar with ohms law. The problem is the 23 ft run, 9' of which is from the ceiling to the floor. I am now looking at mounting the combiner down in the wiring chase. I might be able to gain 3 to 5 ft. It also depends on which calculator I use. However, 10awg wire is waaaaaay too small. When they use 10awg on the individual panels, it's 9amps for 10 ft which is a loss of 1.54%. It should be obvious that quadrupling the current and doubling the length simply will not work.
Tomorrow when the sky isn't looking like lightning is possible I will go on the roof to determine if/how I can get the wires down the fan opening. From there it looks simple.
