MPPT Technology Introduction

MPPT means Maximum Power Point Tracking, it is more advanced solar charging mode. In view of
nonlinearity feature of solar panels, there is a Maximum Power output Point(P
changing light intensity and temperature. Using traditional PWM solar charge controller, the voltage of
solar panel will be clamped by battery, the voltage can not be maintained at P
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%.
The solar panel used for 12 system Vpp is 17V, due to the constant current characteristic of solar
panels, when the 12V battery is charged by solar panel, the voltage of solar panel will be clamped by
battery. If the max charging current is 10A at this time, then the input power to the battery= 10A x 12V
=120W, not yet completely play the maximum utilization rate of solar panels. MPPT controller could
adjust the voltage and current of solar panels to reach Max output power, the input power to the
battery= 9A x 17V x 0.98(circuit exchange efficiency)=150W, it can be seen that the MPPT controller
could significantly improve the charging efficiency.
