* Yamaha Boost Technology™ (YBT) - The EF3000iSEB model boosts output by adding battery voltage to alternator when needed. The Boost Control Unit (BCU) senses when extra power is needed and boosts the output for up to 10 seconds, ample time to give air conditioners, power tools and equipment that extra boost of power they need to start quickly and efficiently. When tools and appliances start quickly their motors start and run cooler increasing the life of the tool and the appliance.
* Inverter System with Pulse Width Modulation - Industry-leading system that 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.
* Noise Block Acoustically designed sound reduction system - The full enclosure is made of sound absorbing material used in key locations inside the enclosure along with newly designed muffler and molded fan produce 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 - Automatically shuts off before oil level is low and cannot be re-started until oil is added. Prevents engine damage and costly repairs while enhancing long-term durability.
* OHV 171cc Engine (Overhead Valve) - Offers increased reliability, low oil consumption, noise-reducing operation and increased peace of mind.
* Long Run Time - Runs Continuously for up to 20.5 hours without refueling (at 1/4 rated load with "Economy Control" function on.
* 12 Volt DC Output (Battery Charging Cables Included) - Recharge 12 volt batteries for RV, auto, marine, aircraft, etc.
* Exclusive Dual Coil Alternator Stator - Reduces noise, fuel consumption and engine wear by running at lower engine speed.
* Centralized Control Panel - Control Panel enables easy access to controls.
* Electric Starter - Effortless starting and easy operation.
