You should only need one charge controller from the panels.............IF they are hooked together AND the controller is large enough to handle them. What is the rating on the controller? Is this setup in an RV or some other use?
You don't need the CTEK charger...........the solar panels with the charge controller will do all that. With those plugged in and in the sun you can take a small digital multimeter and see what kind of DC voltage they are puting out from the leads. Most of the time you would expect to see something around 18 VDC or so. Those haven't been the most reliable units..........Hope that proves helpful here. Please get back to me if you need more as all follow ups are included in our fee.
