MPPT Technology Introduction
MPPT means Maximum Power Point Tracking. It is a more advanced solar
charging mode. According to the nonlinearity feature of solar panels, there is a
Maximum Power output Point(P
on its power curve, and this point under
changing light intensity and temperature. Using traditional PWM solar charge
controller, the voltage of solar panel will be clamped by battery, and the voltage can
not be maintained at P
to charge the battery, which greatly reduce the utilization
rate of solar panels. MPPT solar charge controller adopts efficient DC-DC power
conversion technology, combining with advanced algorithm to track the MPP of
solar panels in (real time) to obtain Max power from solar panel for charging battery.
Compared with PWM controller, MPPT solar charge controller could increase the
energy utilization rate around 15%-30%.
The Vpp of solar panel used for 12 system is 17V. When the 12V battery is
charged by solar panel, the solar pane voltage will be clamped by battery as a result
of the constant current characteristic of solar panels. If the max charging current is
10A at this time, then the input power to the battery= 10A x 12V =120W, which not
yet completely achieve the maximum utilization rate of solar panels. However,
MPPT controller could constantly adjust the voltage and current of solar panels to
reach Max output power, and therefore the input power to the battery= 9A x 17V x
