EcoFlow Smart Generator 4000 (Dual Fuel)

EcoFlow Smart Generator 4000 Dual Fuel: outdoor backup generation with smart system integration

The EcoFlow Smart Generator 4000 (Dual Fuel) is a fuel-powered option for longer outages and compatible battery-system charging. Compare it when you need a larger generator and have a suitable outdoor operating location.

Key specifications and configuration

  • Rated output: 3200W on gasoline or 2900W on LPG.
  • Peak output with X-Boost: 4000W; this is not the continuous rating.
  • U.S. electrical specification: 120V, 60Hz.
  • DC charging and automatic start-stop require a supported EcoFlow system.

Confirm supported system functions

Check the host compatibility chart for DC charging and automatic start-stop, and confirm required cables. These features are not supported with the EcoFlow RIVER series or DELTA Pro Ultra. Choose loads by rated output on the selected fuel, and plan refueling and maintenance according to the manual.

If you are assembling a complete backup setup, confirm compatibility with your current station model and intended loads. Browse DELTA power stations to compare the battery side of a setup.

Outdoor operation and shipping restriction

Operate this fuel-burning generator outdoors only, at least 20 feet from doors, windows and vents, with exhaust directed away from occupied areas. Never operate it indoors or in a garage. Follow the manufacturer\'s safety and maintenance instructions.
