Small But Mighty
Quiet, fuel efficient, and power clean enough to run sensitive electronic equipment all in a portable 28-lb package.
Top Features
The EF1000iS weighs in at 27.9 pounds, making it extremely portable.
Noise Block is Yamaha's acoustically engineered sound reduction system which helps make the EF1000iS among the quietest portable generator in its class. (47 dBA to 57 dBA - 1/4 rated to rated load).
Gasoline petcock lets you shut off the gas to run the carb dry for storage and helps prevent stale gas problems.
The EF1000iS 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 12 hours at 1/4 rated load on a tank of gas.
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.
The Auto Warm-up feature automatically increases engine speed for 4~6 minutes to ensure smooth power delivery during cold start ups.
Yamaha's Oil Watch Warning System helps prevent engine damage from low oil and provides added peace of mind..
Features
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
Exclusive dual coil alternator stator — Greater output at a lower engine speed for reduced noise, fuel consumption, and engine wear
12 Volt DC output, battery-charging cables included — Recharge 12-volt batteries for RV, auto, marine, etc.
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
Factory Warranty — Covers the entire generator for defects in parts and workmanship for three (3) years when the generator is used for non commercial, industrial or rental use. When the generator is used for commercial, industrial or rental use, Yamaha covers the generator for two (2) years
