Working Principle
1. Definition MPPT, known as Maximum Power Point Tracking, is a kind of electrical system that enables PV panels to output more power by adjusting the working state of electrical modules, which can effectively store the DC power emitted by solar panels in the battery. 2. MPPT controller principle First of all, the main circuit DC voltage and output current are detected, then the output power of the solar array is calculated, and finally the tracking of the maximum power point is realized. 3. Practical application The instantaneous output power (U*I) of the solar module moves on this U-I curve. The output of the cell module is affected by the external circuitry. Maximum power tracking technology is the use of power electronics with appropriate software to make the battery module always output the maximum power. Without maximum power tracking technology, the output power of the battery module will not be able to reach the optimal (large) value in all cases, which reduces the utilization of the solar module.
