I have 8 x 155ah 12v agm batteries I would like to put into service(new condition). At present, I have 12, 100w, 12v panels(Vmp: 17.4v, Voc: 21.6v, Imp: 5.75a, Isc: 6.32a), & 4, 140w, 12v panels(Vmp: 17.8v, Voc: 21.7v, Imp: 7.87a, Isc: 8.6a). I intend to buy Morningstar MPPT 30, 45, or 60 C.C., or a combination of any of the three, to charge my 12v battery bank, connected in parallel, for a total of 1240ah. My question is, what would be the best wiring configuration of my solar panels, into which of these Charge Controllers? Yes, I did try Morningstar's String Calculator, yet I couldn't figure out how to configure the string array into which, or how many of these particular C.C.s. They say(mm-hmm), these batteries should last 10-12 years, with proper care & charging. Any reply or help is greatly appreciated. Thanx.
