Introduction of MPPT solar controller

MPPT means Maximum Power Point Tracking, it is more advanced solar charging mode. In view of feature of solar panels, there is a Maximum Power output Point, and this point under changing light intensity and temperature. Using traditional PWM solar charge controller, the voltage of solar panel will be damped by battery, the voltage can not be maintained at charge the battery, greatly reduce the utilization rate of solar panels. MPPT technology adopt high efficiency DC-DC power transform technology, with advanced algorithm to track the MPP of solar panels in actual time to obtain Max power from solar panel for charging battery. Compare with PWM controller, MPPT solar charge controller could increase the energy utilization rate 15%-30%.


Feature:
