With the advanced dual-peak or multi-peak tracking technology, when the solar panel is shadowed or part of the panel fails
resulting in multiple peaks on the I-V curve, the controller is still able to accurately track the maximum power point. A built-in maximum power point tracking algorithm can significantly improve the energy utilization efficiency of photovoltaic systems, and raise the charging efficiency by 15% to 20% compared with the conventional PWM method. A combination of multiple tracking algorithms enables accurate tracking of the optimum working point on the I-V curve in an extremely short time.
