Cummins Onan Marine Generators offer the most innovative product line available. Cummins Onan digital generator sets, the QD™—Quiet Diesel—and QG™—Quiet Gasoline—Series give you smart power with extensive diagnostics. Our digital generator models from 4–99 kW are the first marine generators with self-monitoring capability and network communication.

The Cummins Onan digital technology is provided by an electronic control that constantly monitors the generator’s operation and alerts the user to potential problems. Detailed information is available at the touch of a button, taking out the guesswork and providing built-in confidence. The controls are highly reliable, bringing a new level of information to the user with worry-free digital technology, providing performance you rely on.

Cummins Onan digital generators offer three network options for viewing generator status information. In addition to the Cummins Onan Digital Display, the network interface broadcasts in the SmartCraft Networked™ protocol or in SAE J1939 CAN protocol, which is well suited for boats that already are using a J1939 network for digital or computer display.

These networked systems simplify and consolidate transmitted data from several sources, including the Cummins Onan generator, through a common databus to a common display conveniently located for the user’s viewing. The user can view generator status, including AC voltage, AC frequency, coolant temperature, oil pressure, battery voltage, and generator hours; be alerted to a pre-alarm condition; and, if the generator shuts down, view the notification and diagnostic message in text. The common display frees up valuable space previously taken by multiple monitoring devices.

The Cummins Onan Digital Display, standard on 40–99 kW models or available as an option on other models, provides user-friendly generator status-at-a-glance including engine and alternator detail, plus displays diagnostic information in text format, making it easy for the user to monitor generator operation.
