The article discusses the experience of operating a wind power complex with a low-power wind power installation (5 kW), the use of which is promising for powering remote oil production facilities, exploration and other types of mining operations. The structure of the studied complex and its characteristics, technical problems that have arisen during operation for 6 years are given. The elements of the wind energy complex - the battery charge regulator and the inverter-converter are considered. The consequences of the mechanical regulator failure of battery charge are considered and recommendations for its replacement are presented. The issues of diagnostics and repair of one of the main elements of the complex - the inverter-converter, its component - DC link are highlighted in detail. Oscillograms of the output voltage of the inverter-converter are presented for different capacities of the DC link and the images of the repaired inverter-converter are given. Recommendations are given on choosing an inverter-converter and setting up the operating modes of the wind energy complex.
