A diesel generator set, or genset, is a self-contained power generation unit comprising an engine and an electrical generator. The engine, fueled by diesel, converts chemical energy into mechanical energy, which then drives the generator to produce electrical energy. Gensets are widely used as backup power sources during power outages or in areas with unreliable grid power. They are also employed in remote locations without access to the main power grid. Gensets come in various sizes, ranging from small portable units to large industrial generators, and are designed to meet diverse power requirements.
