Abstract
A power generator incorporates an engine and a generator driven by the engine. The generator incorporates a sound insulation cover that allows for efficient cooling of the various internal components. A fan draws in cooling air through one or more cooling air vents to cool a battery, a DC/DC converter, an electronic module, the engine, the generator, and the muffler. The insulation cover provides quiet operation and efficient cooling of the engine-driven generator.
