I am in the process of designing my wiring diagram for a number of solar arrays, i have 16 x 200w panels, ratings on panels are 8.27amp and Voc max 32.51. My charge controller is mppt 40amp max input voltage 140v and battery bank 48v.
I was planning on 4 strings with four panels in series, (Voc max 130.04 still at 8.27a) and then connected to combiner in parallel, (Voc max still 130.04 but 33.08a) now, if i use the ratings on the panels to ascertain my totol amps that is 33.08amps, however i want to be sure, i know i have 3200w from the panels, so what voltage do i use for the division of the total watts to be sure i do not overload the amps that are going to my controller ??
Many thanks Mike.
