MUC-MB series adopted with auto cool, high conversion efficiency, LCD display and free PC software. It features an  efficient MPPT control algorithm to track the maximum power point of the PV array in any environment, Greatly improve the utilization of solar panel.

MPPT controller can improve the utilization efficiency of the solar array by 20% - 60% better than the PWM controller (the efficiency changes according to the different usage environment background). In practical application, multiple MPPT points may occur in the array due to the blocking of clouds, branches, or snow cover, but only one of these MPPT points is the actual maximum power point, as shown in the figure below:
