Gensets are widely used in various sectors such as industrial, commercial, residential, and emergency backup applications. They come in different sizes, power capacities, and fuel types, including diesel, gasoline, natural gas, and biogas. In China, the gensets market has been growing steadily due to the increasing demand for reliable power supply, especially in remote areas and during peak power consumption periods.
