Maximum power point tracking (MPPT), [1] [2] or sometimes just power point tracking (PPT), [3] [4] is a technique used with variable power sources to maximize energy extraction as conditions vary. [5]
A power optimizer is a DC to DC converter technology developed to maximize the energy harvest from solar photovoltaic or wind turbine systems. They do this by individually tuning the performance of the panel or wind turbine through maximum power point tracking, and optionally tuning the output to match the performance of the string inverter (DC to AC inverter).
A charge controller with MPPT capability frees the system designer from closely matching available PV voltage to battery voltage. Considerable efficiency gains can be achieved, particularly when the PV array is located at some distance from the battery.
Performing maximum power point tracking (MPPT), a solar inverter samples the output (I-V curve) from the solar cell and applies the proper electrical load to obtain maximum power. An AC ( alternating current ) solar panel has a small DC to AC microinverter on the back and produces AC power with no external DC connector .

The maximum power principle or Lotka's principle [1] has been proposed as the fourth principle of energetics in open system thermodynamics. According to American ecologist Howard T. Odum , "The maximum power principle can be stated: During self-organization, system designs develop and prevail that maximize power intake, energy transformation ...
Modern inverter or maximum power point tracker (MPPT) are able to measure the IV curve of the connected string (series circuit of multiple PV modules). [5] In a PV module under operation, the extreme conditions are open-circuit and short-circuit. At open-circuit, the voltage is maximum (open-circuit voltage V OC) and the current zero.
Inverter for grid-tied solar panel Three-phase grid-tie inverter for large solar panel systems. A grid-tie inverter converts direct current (DC) into an alternating current (AC) suitable for injecting into an electrical power grid, at the same voltage and frequency of that power grid.
