What is an MPPT Charge Controller?

An MPPT, or maximum power point tracker is a DC-to-DC converter that optimizes the power between the solar panel array, and the battery bank. Basically, they convert a higher voltage DC output from solar panels down to the lower and consistent voltage needed to charge batteries.
