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.
If it starts from 13.9 with controller connected to battery, and goes to 16, then this built-in controller is either bad or is not wired properly by the manufacturer, or is stuck in Equalize mode (if it has such a mode). In either case this is bad for battery.
I never liked those kits with unknown controllers. For this one they don't even provide any specs other than "a built-in controller with 5m alligator clips". Welcome to era of China.
