Maximum Power Point Tracking (MPPT) charge controllers are essentially “smart” DC-to-DC transformers. In most cases, MPPT charge controllers are said to provide the most efficient possible solar charging by converting excess voltage and minimizing overall power loss. MPPT charge controllers are great for large or growing systems and are currently the only technology available to use in a grid-tied solar energy system.
