Top Features:

  • Yamaha generators have the longest emission engine durability ratings issued by the Environmental Protection Agency and the California Air Resources Board.
  • The EF1000iS weighs in at 27.9 pounds, making it extremely portable.
  • Noise Block is Yamaha’s acoustically engineered sound reduction system which helps make the EF1000iS among the quietest portable generator in its class. (47 dBA to 57 dBA – ¼ rated to rated load).
  • Gasoline petcock lets you shut off the gas to run the carb dry for storage and helps prevent stale gas problems.
  • The EF1000iS features Smart Throttle, a load sensing rpm control that allows greater fuel efficiency and noise reduction by automatically adjusting engine speed to match the load. It will run up to 12 hours at ¼ rated load on a tank of gas.
  • The Yamaha EF1000iS inverter generator supplies clean, high quality power. The EF1000iS – with its inverter system – features Pulse Width Modulation (PWM) so voltage stability is within ± 1%, and frequency stability is ± 0.1 HZ. Its pure sine wave is as clean as or cleaner than public utilities power.
  • The Auto Warm-up feature automatically increases engine speed for 4~6 minutes to ensure smooth power delivery during cold start ups.
  • Yamaha’s Oil Watch Warning System helps prevent engine damage from low oil and provides added peace of mind..
