What is MPPT?

Definition：
MPPT (Maximum Power Point Tracking) is an algorithm and technology used to adjust the output voltage and current of a power supply system (such as solar photovoltaic panels, wind turbines, etc.) in real - time so that it always operates at the maximum power point (Maximum Power Point, MPP), thereby maximizing the acquisition and utilization of renewable energy.

Working Principle

MPPT in photovoltaic systems:

• Output characteristics of photovoltaic cells: The output power of photovoltaic cells changes with changes in light intensity and temperature. Its output characteristics are represented by a curve.

• Maximum power point (MPP): Under different light intensity and temperature conditions, there is a point on the output characteristic curve of photovoltaic cells where the output power is the largest, that is, the maximum power point.

• MPPT algorithm: By detecting the output voltage and current of photovoltaic cells in real time, calculate the current optimal operating point, and by adjusting the parameters of the inverter or charge controller, make the system always work near the maximum power point.

MPPT in wind power generation systems:

• Output characteristics of wind turbines: The output power of wind turbines depends on wind speed and generator speed.

• Maximum power point (MPP): Under different wind speed conditions, there is a point on the output characteristic curve of wind turbines where the output power is the largest.

• MPPT algorithm: By adjusting the blade angle or generator speed of wind turbines, make the system always work near the maximum power point.
