I just connected my solar kit (160w cmp12 controller)and the voltage while connected to the rv batteries reads 16.55v. Is this normal or too high? Sorry but im new to this.
14.4 volts in bulk and absorption and 13.2 volts in float would not properly charge and maintain my batteries. Hence, the inexpensive controllers won't always give one what is needed. Be nice to your batteries!
