Mppt solar charge controller, standing for Maximum Power Point Tracking, represent a significant advancement in solar energy control systems compared to traditional counterparts. These controllers play a crucial role in optimizing the performance of solar panels, batteries, and loads within a photovoltaic system, serving as the brain of the entire setup.

MPPT control is generally achieved through a DC/DC conversion circuit.

The photovoltaic array and the load are connected through a DC/DC circuit, and the maximum power tracking device continuously monitors the current and voltage changes of the photovoltaic array. It then adjusts the duty cycle of the PWM drive signal to the DC/DC converter based on these changes.

For linear circuits, when the load resistance equals the source's internal resistance, the power supply has its maximum power output.

Although photovoltaic cells and DC/DC conversion circuits are highly nonlinear, in an extremely short time frame, they can be considered as linear circuits. Therefore, by adjusting the equivalent resistance of the DC-DC conversion circuit to always be equal to the internal resistance of the photovoltaic cell, the maximum output of the photovoltaic cell, and hence MPPT for the solar panels can be achieved.
