EF1000iS Generator

Yamaha EF1000iS Generator

The Yamaha EF1000iS inverter generator is the ultimate in lightweight portable electricity. The EF1000iS - with its inverter system - features Pulse Width Modulation (PWM). That means these generators deliver clean power so you can use them confidently for powering computers, solid-state appliances with built-in computer functions or microcomputer-controlled power tools.

 
Lightweight Design / Easy to Carry - Newly designed exterior and compact lightweight inverter unit reduces weight to 27.9 lbs. Lightest weight generator in its class.
Noise Block Acoustically designed sound reduction system - Molded casing, noise-absorbing glass wool construction and a newly designed muffler produce unbeatable noise reduction.
Long Run Time - Runs continuously for up to 12 hours without refueling (at 1/4 load with "Economy Control" function on).
Smart Throttle Load sensing throttle control - Automatically adjusts engine speed to precisely match load, resulting in greater fuel efficiency and noise reduction.12 Volt DC Output (Battery Charging Cables Included) - Recharge 12 volt batteries for RV, auto, marine, aircraft, etc.
Inverter System with Pulse Width Modulation - Industry-leading system produces higher-quality and cleaner electricity. Results in pure sine wave as clean or cleaner than commercial power and can operate products with built in microcomputers.
Exclusive Dual Coil Alternator Stator - Lower engine speed. Reduced noise, fuel consumption and engine wear.
Centralized Control Panel - Control panel enables easy access to controls.
Fuel Petcock - Reduces carburetor contamination by turning off gasoline flow and allowing the carburetor to run dry.
OHV 50cc Engine (overhead valve) - Provides improved efficiency, increased reliability, low oil consumption and noise-reducing operation.

Powerful Inverter System Delivers Cleaner Electricity
The EF1000iS 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.

Smart Technologies for Optimal Fuel Efficiency
The EF1000iS is exceptionally fuel efficient, able to run for up to 12 hours without refueling when in Economy mode. 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
At only 27.6 pounds, this generator is also 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. For added convenience, the EF1000iS is even able to recharge 12-volt batteries with its 12-volt DC output, making it ideal for RV, auto, and boat owners.

Noise Reduction for Quiet Operation
The EF1000iS uses noise reduction technologies to ensure the quietest operation possible. Featuring a special sound-blocking design, the generator has a noise-absorbing glass wool construction, which helps dampen noise even during heavy operation. Along with the EF1000iS' super-quiet muffler, it helps keep noise to a minimum.

The EF1000iS is backed by a two-year warranty.
