I didn't think you could run 2 solar charge controllers in parallel? Doesn't one sense the output of the other and interpret that as a fully charged battery, cutting 1/2 your solar array out?
Since the charge controllers monitor battery voltage that would only happen when the battery is fully charged. Or at least one of the controllers thinks it is.
Once the batteries approach full charge the controller set to the highest voltage would be the last one providing current. For example, if controller A is set to 14.38v and controller B is set at 14.42v, controller A would stop providing current at 14.38v then controller B would provide the last bit of charge until the batteries reach 14.42v. But I doubt that's going to be a problem.
