I have been having a problem with my Charge Controller erroring out with an over current alarm. It shuts off for 10 seconds then comes back on.
I think this is due to the fact that my pump is 7.0A max, but the charge controller has a 2 amp output. It seems to peak at about 6 amps before the protection circuit kicks in.
I think I'm going to try to run the pump from the batteries direct, and see how things do that way.
