Features

Top Features:

  • The EF2000iSv2 incorporates a completely new controller with advanced programming resulting in improved output characteristics between 1600w-2000w operation ranges. The addition of the new programming allows the EF2000iSv2 the ability to power a much wider range of applications than previous generation EF2000iS.
  • If you need extra power the EF2000iSv2 has you covered—a convenient parallel function lets you connect two generators to deliver up to 30 amps.
  • The EF2000iSv2 is powerful, portable and retro-modern and delivers maximum output with minimum effort. It weighs a mere 44 pounds, making it easy to transport. Super Light weight for 2000 watts.
  • The EF2000iSv2 is fitted with Yamaha’s most technologically sophisticated muffler. It’s So quiet that you can have a conversation near one and may not realize it is running. (51.5 dBA to 61 dBA – ¼ rated to rated load).
  • It is very compact (2.2 cu.ft.) which makes it easy to store and transport.
  • Long Run Time - The EF2000iSv2 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 10.5 hours at ¼ rated load on a tank of gas.
  • Gasoline petcock lets you shut off the gas to run the carb dry for storage and helps prevent stale gas problems.
  • Fuel gauge allows fuel level to be seen at-a-glance.
  • The Yamaha EF2000iSv2 Inverter generator supplies clean, high quality power. The EF2000iSV2 – 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.
  • Yamaha generators have the longest emission engine durability ratings issued by the Environmental Protection Agency and the California Air Resources Board.

Features:
