A generator set, also known as a genset or power generator, is a piece of equipment that generates electricity by converting mechanical energy into electrical energy. A typical generator set consists of an engine, alternator, and control panel.
The engine is the primary component of a generator set and is responsible for converting fuel into mechanical energy. Depending on the size and application of the generator set, the engine may run on gasoline, diesel, natural gas, propane, or other types of fuel. The engine is typically connected to the alternator through a coupling or belt drive.
