Abstract

The present disclosure relates to an engine-generator having an engine, an electrical generator and a control panel configured to control the engine-generator. The engine-generator includes a first electrical starter having a first battery, a first solenoid configured to receive a starting signal from the control panel and a first starter motor configured to crank the engine when the first solenoid receives the starting signal from the control panel. The engine generator also includes a second electrical starter including a second battery, a second solenoid configured to receive a starting signal from the control panel and a second starter motor configured to crank the engine when the second solenoid receives the starting signal from the control panel.
