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.
