MPPT Solar Charge Controller

What is an MPPT Solar Controller?


This section covers the theory and operation of "Maximum energy point tracking", as used in solar charge controllers.

An MPPT or maximum power point tracker is an electronic DC to DC converter that optimizes the correspondence between the solar panel (photovoltaic panels) and the battery bank or the electrical network. Simply put, they convert a high voltage DC output from the solar panels (and some wind generators) to the lowest voltage needed to charge the batteries.
