#1 Are you sure your batts will take more than 12A of charge current?
#2 I have a single 80 watt panel and regularly see about 4.6-4.8A. For 25 panels, and all that wire, mess etc. and expense you really should have considered a dedicated mount for some mono or polycrystalline panels of decent size.. Even a single 130W panel like a Sharp or Kyocera will give you around 7A of charge current.
#3 You likely have some serious shading issue with all those panels which really hurts solar output.
#4 What Model Morningstar controller are you using?
#5 How is it wired gauge wise? Where are they all tied together?
