All this stuff is good for experience but in my
opinion...you simply don't have enough electrical
source....a 5 watt PV isn't enough for 25 amp/hr.
Instead I would be checking on the input from
the PV to the battery/batteries.
Even with my bad math I figure that a 12 watt
would be 1 amp....so what you have is something
that will input about 400 Ma and that is being
very optimistic....
...I use a pedal generator to charge 700Ma batteries
6 in series 7.2vdc to start fully
charged they will read 8.4vdc I pedal the gen
at a 400 Ma rate (very leisurly) and it takes
about 45 minutes even at that!
So I figure that a 12 volt 5 smp/hr battery
from 12 volt to 13.50 would take at least 4 hrs
IF you were charging at the rated 5watts.
