MPPT control is generally accomplished through a DC conversion circuit. The photovoltaic cell array and the load are connected through a DC circuit. The maximum power tracking device continuously detects the current and voltage changes of the photovoltaic array, and according to the changes, adjusts the duty cycle of the PWM drive signal of the DC converter. Make adjustments. In general, the MPPT controller will track the maximum power point in the solar panel in real time to maximize the efficiency of the solar panel. The higher the voltage, the more power can be output through maximum power tracking, which improves the charging efficiency.

The mppt solar controller can detect the power generation voltage of the solar panel in real time. It is used in the solar photovoltaic system to coordinate the work of the solar panel, the battery and the load. It is the brain of the photovoltaic system. By adjusting the working state of the electrical module, the mppt controller enables the photovoltaic panel to output more electrical energy. The electrical system can effectively store the DC power emitted by the solar panel in the battery, and track the highest voltage and current value, so that the system can output the maximum power. Charge the battery.
