Description

The Yamaha EF1000iS is small but mighty with a lightweight, easy to carry design. A compact lightweight alternator reduces the weight to 27.9 lbs., the lightest weight in its class. It 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 50cc Overhead Valve (OHV) engine provides a noise-reducing operation with improved efficiency, increased reliability, and low oil consumption. The Auto Warm-up feature automatically increases engine speed for 4-6 minutes to ensure smooth power delivery during cold start ups. The exclusive dual coil alternator stator offers greater output at lower engine speed for reduced noise, fuel consumption, and engine wear. Smart Throttle, a load sensing rpm control, provides 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. Noise Block, an acoustically engineered sound reduction system, helps make this among the quietest portable generators in its class. The Oil Watch Warning System helps prevent engine damage from low oil and provides added peace of mind. The large fuel fill access has a wide mouth to reduce spilling and overflows during refueling. The gasoline petcock lets you shut off the gas to run the carb dry for storage to prevent stale gas problems. The centralized control panel offers easy access to controls. With 12 Volt DC output and battery-charging cables included you can recharge 12-volt batteries for your RV, auto, marine, etc. Yamaha generators have the longest emission engine durability ratings issued by the Environmental Protection Agency (EPA) and the California Air Resources Board (CARB). This generator is 50 state legal and meets emissions regulations, including CARB.
