1. Using advanced dual- or multi- tracking technology, when the solar panel is shaded or part of the solar panel is damaged, the I-V curve have multiple peaks, and the controller can still accurately track the maximum power point 2. Built-in maximum power tracking algorithm can significantly improve the utilization efficiency of the photovoltaic system, which is about 25% higher than the traditional PWM charging efficiency 3. Combining multiple tracking algorithms, it can accurately track the optimal working point of the I-V curve in a very short time. 4. The MPPT tracking efficiency can reach up to 99.9% 5. The circuit conversion efficiency is as high as 98% with the use of advanced digital power technology, Weight: 1.543235834 Pounds, Manufacturer: Hipzeepo
