Looks good, have you had a close look at the charge controller's voltage? I have an identical unit (I think - I'll check the exact model no. tomorrow) and its voltage settings out of the box were way too low.
It open circuited the panel when the battery was at about 13.4V, and reconnected at 12.8V, not enough to even maintain a proper float charge IMO.
I opened mine up and put a couple of Schottky diodes in series with the Zener that was sticking out of the goo the circuit board was cast in, got the switching voltages up to a more respectable 14.3V/ 13.7V respectively.
I might have been unlucky and just got a dud regulator. If yours has the same problem I can post pictures of my "repair" if you want.
What sort of battery are you charging? How big is it, how big is your panel? 13.4V is too low for any "12V" lead-acid, but if you have an SLA (gell cell) then 14.3V is too high - just use one Schottky and the max voltage should be around 13.8 - 13.9V.
