The MPPT solar controller can detect the power generation voltage of the solar panel in real time, and track the highest voltage and current value (VI), so that the system can charge the battery with the maximum power output. Applied in solar photovoltaic system, it is the brain of photovoltaic system to coordinate the work of solar panel, battery and load.
Features of MPPT controller:
1. The built-in maximum power tracking algorithm can significantly improve the energy utilization efficiency of the photovoltaic system, which is about 15%-20% higher than the traditional PWM charging efficiency.

2. Even if the battery panel is partially damaged or shaded by trees, the controller can still accurately track the maximum point power.
3. Using advanced digital power technology, the circuit energy conversion efficiency is as high as 98%.
4. The combination of various tracking algorithms can accurately track the best working point within 1 second, and the MPPT tracking efficiency can reach up to 99.9%.
5. It has a current-limiting charging mode. When the power of the battery board is too large and the charging current is greater than the rated current, the controller automatically reduces the charging efficiency and makes it work at the rated charging current.
