Description
Introduction of the MPPT
The Maximum Power Point Tracking MPPT system is an advanced charging technology that enables solar panels to output more power by adjusting the working state of electrical modules. Due to the non-linearity of a solar array,there is a maximum energy output point maximum power point on the curve of the array. Traditional solar charge controllers switch charging technology and PWM charging technology cannot charge batteries at this point, thus unable to obtain the maximum energy of solar panels. However, the solar energy charge controller equipped with the MPPT control technology can track the maximum power point of a solar array at any time in order to gain maximum energy for battery charging.Take the 12V system for example. The peak voltage of solar panels Vpp is around 17V and battery voltage is about 12V. Generally, when the solar charge controller is charging a battery, the voltage of solar panel is maintained at about 12V, indicating that the maximum power is not used. MPPT solar charge controllers provide a solution to that problem by constantly adjusting the input voltage and current of solar panels, therefore maximizing input power.
Compared with conventional PWM solar charge controllers, MPPT solar charge controllers bring out the maximum power of solar panels and provide greater charging current. Generally speaking, MPPT solar charge controllers can improve energy utilization rate by 15 ~ 20 over PWM solar charge controllers
Advantage of controller
1.Adopt industrial-grade main controlchip, 16-level AD sampling accuracy, temperature, chargingcurrent, accurate real-timed isplay, and power generation at a glance.
