Any fuses connected? I put blade fuses on my 12v setups, helps narrow down any problems. Is the pump running constantly? If so what AH rating is your battery? I ran 100ah deep cycle batteries for my setup.

Where do you put the fuse? Between battery and pump?

I personally put blade fuses on all 3 connections. It might be overkill but works for me. If your battery is low amperage it may not be keeping up with the pump or the panel may not be keeping up with the demand on the battery.

Also have a play with the buttons on the charge controller, mine is similar and if I remember correctly there's a constant on option or timer and some other options I never use.
