Description

Technical field [0001] The invention relates to a solar photovoltaic integrated grid-connected controller and method, in particular to a control device and method for a solar photovoltaic industrial power generation system. Background technique [0002] The solar photovoltaic industry is one of the emerging industries in the 21st century. While solar photovoltaic power generation systems continue to improve the photoelectric conversion efficiency and service life of solar cells, the development and application of their control devices is the most important and critical part of the solar photovoltaic system. The traditional controller controls the number of input arrays of the solar cell array to meet the charging requirements of the battery, and at the same time supplies power to the AC load through the inverter device. The main technical problems and shortcomings of this technology are that the independent component design does not have parallel or grid-connected operation; the ...
