Yeah, I would have to run 2 sets of cables from the porch roof. But If i can go 2S2P with a cheaper CC I might do that. Not enough room to add more Sun gold panels but 3600w is not bad for what I am doing. And if I go 2S2P that would only be 80Voc so I could go with a 100 CC but that might not utilize the Renegy panels to their full potential so I'll have to think about that. With a future battery bank addition I might go large anyway.
