MPPT Charging Introduction:
The full name of MPPT "Maximum Power Point Tracking”, is an advanced way of charging. The MPPT controller not only can real-time detect the power of solar panels, but also can track the highest voltage current value (VI), which make the system with the highest efficiency for battery charging. Compared with the conventional PWM controller, the MPPT controller can make solar panels with maximum power, so it can provide maximum charging current. Generally speaking, the charging efficiency of MPPT controller is 15%~20% higher than PWM mode.

Because the peak voltage of solar panels (Vpp) is around 17V and the battery voltage is around 12V, when the common controller charging, the voltage of solar panels is around 12V, which can’t reach the maximum power. MPPT controller can overcome this problem, it can adjust the input voltage and current of the solar panels constantly in order to achieve the maximum input power.

At the same time, because of the different environmental temperature and light conditions, the maximum power point tracking often change. According to different conditions, the MPPT controller can adjust the parameters constantly in order to achieve the system near the maximum working point at any time.
