Abstract

A solar energy controller is designed aimed at low rate of solar energy utilization, short life of battery ,circuit instability and other issues. It adopts conductance increment method to adjust the PWM control signal duty cycle, and to achieve the maximum power point tracking (MPPT)of solar energy output after the control unit analysis and calculation on the solar collecting voltage and current signals. In the battery charging and discharging process, it takes disconnect loop and connect the load to detect the end voltage of battery accurately, which effectively avoids occurrence of battery overcharge and over discharge. After the test, it proves that solar energy controller can effectively control the output of solar energy and the charge and discharge process of battery, and it ultimately improves the utilization efficiency of solar cell and prolongs the service life of battery.
