Yamaha EF1000iS Inverter 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.
