47dBA - 57 dBA
Engine: OHV, air-cooled, single cylinder, 4-stroke
Engine Speed @ 1/4 Load: 3000 rpm
Lightweight, easy to carry design — Compact lightweight alternator reduces weight to 27.9 lb., the lightest weight in its class.
Smart Throttle, load sensing rpm control — Greater fuel efficiency and noise reduction by automatically adjusting engine speed to match the load.
Auto Warm-up — Automatically increases engine speed for 4~6 minutes to ensure smooth power delivery during cold start ups.
12 Volt DC output, battery-charging cables included — Recharge 12-volt batteries for RV, auto, marine, etc.
Exclusive dual coil alternator stator — Greater output at a lower engine speed for reduced noise, fuel consumption, and engine wear.
Centralized control panel — Easy access to controls.
Gasoline petcock lets you shut off the gas to run the carb dry for storage — Prevents stale gas problems.
50cc Overhead Valve (OHV) engine — Noise-reducing operation with improved efficiency, increased reliability, and low oil consumption.
Large fuel fill access — Wide mouth fuel fill reduces spilling and overflows during refueling.
EPA & CARB Emission Engine Durability Rating — Yamaha generators have the longest emission engine durability ratings issued by the Environmental Protection Agency and the California Air Resources Board.
50 state legal — Meets emmision regulations, including CARB.
The ultimate in lightweight portable electricity! Yamaha Portable Generators give you the power you need where you need it. Pulse Width Modulation (PWM) delivers clean power so you can use it confidently for powering computers, solid-state appliances with built-in computer functions or microcomputer-controlled power tools. Lightweight and easy to carry. Noise Block acoustically designed sound reduction system produces unbeatable noise reduction. Smart Throttle Load sensing throttle control automatically adjusts engine speed to precisely match load, resulting in greater fuel efficiency and noise reduction. Oil Watch warning system and electrical overload breaker help prevent engine damage. Super-quiet muffler with USFS-approved spark arrestor eliminates errant sparks. Overhead valve engine with cast iron cylinder liner is efficient, reliable, powerful providing long life and excellent heat dissipation. DC output recharges 12 volt batteries for RV, auto, marine, aircraft, and more with included battery cables.
The Yamaha EF1000iS inverter generator supplies clean, high quality power. The EF1000iS – 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.
At 27.9 lbs., it is the lightest weight generator in its class. Runs continuously for up to 12 hours without refueling (at 1/4 load with “Economy Control” function on). Exclusive dual coil alternator stator means lower engine speed, reduced noise, fuel consumption and engine wear. Centralized control panel enables easy access to controls. Fuel petcock reduces carburetor contamination by turning off gasoline flow and allowing the carburetor to run dry. Large fuel fill access features wide mouth for reduced spillage and overflow during refueling.
