Key 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 – ¼ rated to rated load)
  • 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 ¼ 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.
Features
  • Lightweight, easy to carry design — Compact lightweight alternator reduces weight to 27.9 lb., the lightest weight in its class.
  • Noise Block, acoustically designed sound reduction system — Molded casing, glass wool insulation, and an advanced designed muffler provide unbeatable noise reduction.
  • 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.
  • Inverter system with Pulse Width Modulation (PWM) control — Can run products with built-in microcomputercontrolled electric tools.
  • 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.
  • EPA & CARB Emission Engine Life Rating — Yamaha generators have the longest emission engine life ratings issued by the environmental Protection Agency and the California Air Resources Board.
  • 50 state legal — Meets emmision regulations, including CARB.
