Cummins Onan QG 7000i DF 7.0kW Commercial Mobile Generator 7HGLCB-8315 EFI Dual Fuel Gas LP Single Phase 120/240V Air Cooled EVAP New - A079U365
The Onan QG 7000i DF is the latest addition to Cummins’ new generation of inverter commercial generators. Outfitted with a variable speed engine and PMA alternator, this generator has low noise and vibration, so you won’t disrupt your neighbors or be jolted awake in the middle of the night.
The QG 7000i DF can be installed for LP or gasoline fueled RVs and has a clean exhaust producing minimal smoke or smell. It also produces clean, consistent electricity that keeps your electronics safe from power surges in a storm when they are plugged in.
This generator also has electronic fuel injection (EFI), which means you don’t have to stop for fuel as often. EFI also means it requires less maintenance so you can spend more time enjoying the journey.
You can also enjoy the convenience of having your QG 7000i DF fully integrated into your coach’s control interface for easy operation and monitoring.
