I'm trying to understand why my solar controller is putting out 22v to charge my 12v Battery. I have a 30w panel I read 22v at the panel and that is what is going into the controller. The same voltage is coming out going to the battery when it says cut out is 14.2v and cut in is below 12. Should i not be getting 14.2 volts going to the battery, I don't want to over charge it or blow the battery.
