Nowadays, solar photovoltaic power generation is considered as one of the new energy technologies having very promising prospects in the world. For stand-alone photovoltaic power generation system, lead-acid storage batteries are needed for supplying electric energy to the load. To protect batteries while ensuring load running normally, safely and reliably, the seamless complementary automatic switching device for user type photovoltaic power generation and utility power grid is designed. The systematic device is composed of three parts, i. e. , voltage signal detection, voltage signal comparison, and peripheral control circuit. Through comparing the magnitude relationship of the detected voltage on both ends of the panels and the minimum operating voltage ( settable) , seamless complementary and automatic switching for utility power grid and photovoltaic power generation system can be implemented by the system. The system features simple structure, low cost, and possesses wide application value.
