Intelligent solar photovoltaic power supply system

The utility model discloses an intelligent solar photovoltaic power supply system. The system comprises a solar cell panel utilizing solar energy for power generation, a controller used for controlling the charging and discharging of a photovoltaic power supply, an inverter used for DC/AC conversion, and a storage battery used for storing the power. The intelligent solar photovoltaic power supply system is advantaged in that the system is capable of effectively utilizing the solar energy and having a dynamic charging and discharging management function, i.e., the system can store surplus electric energy in the storage battery when a load is smaller than output power of a solar assembly and utilize the storage battery as a supplement power supply to satisfy the need of the load when the load is greater than the output power of the solar assembly; and the system has a solar assembly maximum power point tracking function, a storage battery protection function, a storage battery balance control function, and other intelligent management functions, and utilizes a lithium battery so as to reduce environmental pollution.
