In this paper mainly introduces solar power inversion device designed mainly include two categories. One circuit is the main circuit; another is to detect the protection circuit. The main circuit including ：SPWM wave a circuit, Driven circuit, against the same circuit, DC/DC circuits and so on. Testing the circuit protection includes ：Owe voltage electrical, over voltage circuit, over current circuit, fault alarm circuit and so on. In the main circuit SPWM wave a circuit mainly adopt the chip EG8010; driven circuit from the chip IR2110; against the same circuit mainly adopt the bridge against all but single phase change. Last on the contrary is power, the computer simulations validate its practicality, and effectiveness. By the design of the major review and study by electricity and electrical and electronic （ boost chopper and inverter circuit ）; automatic control and expertise in this design is to
