I have the Victron 150/85 SCC. I have four 160W panels and two 270W panels. They have the same operating current of 8.77A. I did try to run all six in series, but it over voltaged my controller during that experiment. I do want to run a couple more panels so I think I'll get another controller and split the sides of the roof for each controller. That'll keep me under 150V on each string and the shading from the ACs won't have such a large impact on production during the lower sun angles.
