I purchased a MPP LV6548 and 24 325W panels to get maximum wattage. When I figure VOC for my low temp I go over max voltage (297.6V). I calculated the suggested panels they use in the manual, they also go over max voltage (278.7V). Maybe I am missing something. Do I drop to 5S2P instead of 6S2P? Panels are 325W VMP 36.2 IMP 8.98 VOC 43.6 ISC 9.42 Coeffientcy .37 Low temp for me is 10F
