Powerful, portable, and efficient, the Yamaha EF2000iS Gas-Powered Portable Inverter delivers maximum electrical output without sacrificing portability. Thanks to its innovative inverter system, the generator is able to generate up to 2,000 watts of clean AC power. It can run up to 10.5 hours continuously without refueling and uses premium technologies to maximize fuel efficiency.
Compact and ergonomic, the EF2000iS is easy to store and transport. View larger.
TwinTech technology allows you to hook up two units for added output. View larger.
Powerful Inverter System Delivers Cleaner Electricity
The EF2000iS is built around an innovative inverter system, which is able to deliver higher-quality, cleaner electricity than competing generators. It produces energy in the form of pure sine waves, which are cleaner and more reliable than most commercial power sources.
In simpler terms, this means that you’ll be able to confidently power delicate machinery without having to worry about the damage caused by unrefined energy. An electrical overload breaker is also included, to prevent generator damage in case of an unexpected overload.
Smart Technologies for Optimal Fuel Efficiency
The EF2000iS is exceptionally fuel efficient, able to run for up to 10.5 hours without refueling when in Economy mode. Its OHV engine runs reliably and dissipates heat efficiently, allowing for both a long life and optimal fuel consumption.
With its Smart Throttle Load feature, the generator is able to dynamically adjust engine speed depending on output, resulting in greater overall fuel efficiency. The generator also features an exclusive dual coil alternator stator, which lowers engine speed and reduces total fuel consumption.
Ergonomic, User-Friendly Design
Weighing 44 pounds, the generator is ultra-portable and features an easy-to-carry design. It has a convenient, centralized control panel, which allows you to easily access all of the generator’s features at the push of a button. It also starts up responsively due to its auto-decompression system, which reduces compression and makes start-up less difficult.
For added convenience, the EF2000iS is able to recharge batteries with its 8A12V DC output, making it ideal for RV, auto, and boat owners. You can even hook up two EF2000iS units for added output, thanks to TwinTech technology. And you won’t have to worry about engine damage due to low oil levels: an oil-watch warning system constantly monitors oil levels and lets you know when an oil change is needed.
Noise Reduction for Quiet Operation
The EF2000iS uses noise reduction technologies to ensure the quietest operation possible. Featuring a special sound-blocking design, the generator has noise-absorbing glass wool construction, which helps dampen noise even during heavy operation. Along with the EF2000iS’ super-quiet muffler and vibration-isolating feet, it helps keep noise to a minimum.
The EF2000iS is backed by a two-year warranty.
