OFF-GRID/GRID-CONNECTED INTEGRATED SOLAR POWER GENERATION SYSTEM AND CONTROL METHOD

摘要

An off-grid/grid-connected integrated solar power generation system and a control method, wherein a system operating mode control manager (2.0) selects an off-grid operating mode or a grid-connected operating mode of the system, and a logic control unit (2.1) controls the working conditions of a power input orientation driver (2.11), a power generation and energy storage driver (2.12) and a power output orientation driver (2.13) according to feedback of the power load conditions of a solar panel (1), an inverter (3), a storage battery charging controller (4) and a storage battery matrix (5), thereby realizing the running of solar energy charging and storage as well as power generation and output of the whole solar power generation system in the off-grid operating mode or the grid-connected operating mode. The solar power generation system and the control method can meet the requirements of a user on the off-grid or grid-connected running of a solar power generation system, and also have the capability of realizing the multifunctional application of storing and backing up the peak power of an external power grid.
