Precisely what is MPPT?
Maximum power point tracking (MPPT) is a new technology used for solar power generation systems to maximize power extraction under various conditions.

MPPT solar charge controller should be the best solution for solar system.

The main functions of the MPPT controller: detect the DC voltage and output current of the main circuit, calculate the output power of the solar array, and realize the tracking of the maximum power point. The perturbation resistor R and the MOSFET are connected in series. Under the condition that the output voltage is basically stable, the average current through the resistor can be changed by changing the duty cycle of the MOSFET, thereby generating current perturbation. At the same time, the output current and voltage of the photovoltaic cell will also change accordingly. The output power and voltage of the photovoltaic cell before and after the disturbance are measured to determine the direction of the disturbance in the next cycle. When the direction of the disturbance is correct, the output power of the solar panel will increase. The cycle continues to perturb in the same direction, on the contrary, it perturbs in the opposite direction. In this way, the perturbation and observation are repeated to make the output of the solar photovoltaic panel reach the maximum power point.
