A dual engine generator has two engines and two inverters and two alternators configured within an inner enclosure. An outer enclosure extends around the inner enclosure to create plenums for airflow. Cooling airflow enters through the outer cover and flows through the plenums and into the inner enclosure to cool the components therein. Airflows out of the inner enclosure and into the plenums and finally exhausts from the outer enclosure. The outer enclosure may have rounded sides to form a pill shaped enclosure. The outer covers are configured to deflect or flex in high wind condition and protect the inner enclosure. The engines are configured above the alternator and inverter and a flow of air reduces heat from the engines from overheating the other components. The mufflers are within the plenums and a flow of exhaust air from within the inner enclosure is directed over the mufflers.
