I've been meaning to ask. What is the function of the Charge Controller connected to my house batteries? How do I know if it is doing its job? Does it alert me to a problem?
It is designed to shut down the current charging the batteries when they are fully charged. It goes to a trickle. It used in solar panel systems as well and can also boost the voltage too.
Yup, basically a voltage regulator, generally used with solar panels.
They vary in degree of sophistication and in amp capacity.
