Only by relying on the progress of science and technology and the largescale exploitation and utilization of renewable energy and new energy can human solve the problem of energy. And solar and wind power are considered the most representative of new and renewable energy, The power technology of solar energy and wind attack world’s attention. Because of wind power and solar power system under external conditions, and only by independent wind or solar power systems often hard to ensure the continuity and consistency of power system therefore, using hybrid power system of plementary scenery to plement each other, realize the continuous, stable power supply. This design mainly for small windlight plementary system of battery charging and discharging control module and inverter module for the design and simulation. The conventional charge controller on the market today on the battery charge and discharge control is unreasonable, and its protection is also inadequate, which makes the battery life to shorten. To solve this problem, the design identifies a solar charge controller based on single chip solution. In the solar energy to battery charge and discharge means, the controller of the functional requirements and the practical application aspects ,making some analysis, pleted the hardware circuit design and software development, to achieve the high efficiency of the battery management. In the inverter part ,the paper use PWM inverter link, and the control chip is PIC16F73,this makes the system simple. In the software design, the paper uses the transient voltage feedback and meanwhile, increase circuit protection function, the paper also elaborates the overall framework of software design and displays program code. Finally, the paper uses single chip puter simulation software the Proteus simulink the system and gives the simulation principle diagram and waveform.
