Reading your posts, in post #5 you say your batteries are 12.5v.
Post #9 shows your obviously mis-wired battery bank.
Post #16 says you have wired the batteries in series.
Based on the above your battery bank is putting out 25 volts. That is enough to prevent anything from working and probably cause some blown breakers and/or fuses.
Are your batteries really 12v batteries?
