Panels producing too much voltage

[littleharbor]

Actually you want 14+ volts Charging your batteries. In a 12 volt system flooded lead acid batteries want up to 14.8 or even more to equalize while sealed lead acid want something in the 14.4 volt range. When your controller is done with the bulk and absorb phases it should float around 13.6 volts.

Hi - I have noticed that in the summer my charge controller is regularly getting over 14 v from my panels which causes it to constantly disconnect (as it should due to the over-voltage protection working) and therefore not charging my battery. Is there a way that I can step down the voltage that they are producing to something usable?
