Tracking (MPPT) photovoltaic battery charge controller with our own technology. It’s main topology adopts in Buck conversion circuit, and uses MCU to adjust the solar panels working point intelligently in order to make the solar panels output its maximum power. When the circumstances change, the... -
Page 5: Structure
(1) Maximum Power Point Tracking technology The controller uses Buck conversion circuit and MCU technology to track the maximum power point to implement the maximum output power of solar panels in different illumination intensity and temperature. The MPPT algorithm increases efficiency of your PV system and decreases the quantity of solar panels. - Page 6 Connecting the solar modules with the controller by reserved connection will not damage the controller. The controller will work normally after connecting with correct polarity. (7) Reverse Current Protection The controller prevents reverse current from flowing into the solar modules...

Page 7: Mppt Technology Instructions
When the illumination intensity and solar panels temperature are fixed, the output power of solar panels is only affected by load impedance. Different load impedance will make the solar panels work at different point and put out the different power. - Page 8 Output voltage is 17.6V, output power is 92W. This point is the state when using MPPT controller. Because of using power conversion technology, the solar panels voltage is not clamped by battery and still works at maximum power point. Compare working point A & B, it is easy to find using MPPT controller can increase the using efficiency of solar panels.
