The paper presents scientific and technical solutions to improve the efficiency of decentralized power supply systems for consumers that implement digital technologies in agriculture. The author’s technology is described, which makes it possible to evaluate the effectiveness of TEG in an extended temperature range, as well as to study the modes of their operation with electric load. The results are given that determine the rational temperature range for hot junction 160 … 200 °C, for cold - 30 … 50 °C. The dependence of the output power on the load current, described by a polynomial of the second degree, is obtained. The regularities of the influence of the load on TEG efficiency are determined. Based on the obtained experimental data, a power source circuit based on a heating device with TEG was developed.
