The operation of Generac generators relies on internal combustion engines. These engines convert the chemical energy stored in fuel into mechanical energy. This mechanical energy, in turn, drives an alternator, which then transforms the mechanical energy into electrical energy, providing a source of backup or primary power. The fuel source dictates the specific engine type and its performance characteristics.
Generac generators provide crucial power security during grid outages, safeguarding homes and businesses from disruptions. Their widespread adoption has stemmed from an increased reliance on continuous power for essential services and equipment. Early models offered basic backup, while contemporary designs feature sophisticated monitoring and automation capabilities, enhancing overall reliability and user convenience.
