The Yamaha EF3000iSEB Generator is one of the most technologically advanced inverter generators available and it is capable of producing clean, high-quality electricity with extremely quiet operation. It features Yamaha Boost Technology (YBT), which boosts output by adding battery voltage to alternator output when needed. The Boost Control Unit (BCU) senses when extra power is needed an boosts output for up to 10 seconds, giving air conditioners, power tools, and other equipment the extra boost of power they may need to start quickly and efficiently. It features a fresh, ergonomic design with a centralized control panel for easy access to controls and four built-in wheels with a parking brake for easy transport and mobility. The inverter system with Pulse Width Modulation (PWM) control can run products with built-in microcomputers, or microcomputer-controlled electric tools. The 171cc Overhead Valve (OHV) Engine provides noise-reducing operation with improved efficiency, increased reliability, and low oil consumption. The electric starter provides effortless starting and ease of operation (battery included). Smart Throttle, a load sensing rpm control, provides greater fuel efficiency and noise reduction by automatically adjusting engine speed to match the load. At ¼ rated load with the Smart Throttle function on, the generator can run for up to 18.6 hours without refueling. The Oil Watch Warning System helps prevent engine damage from low oil, avoiding costly repairs and minimizing down time. With Noise Block, the acoustically designed sound reduction system, sound absorbing material is used in key locations and does not resonate sound. A newly designed muffler and molded fan produce unbeatable noise reduction at 53-60 dBA. 12 Volt DC output, with battery charging cables included, allows you to recharge 12-volt batteries for your RV, auto, marine, etc. It is 50 state legal and meets emission regulations, including CARB. Yamaha generators have the longest emission engine life ratings issued by the Environmental Protection Agency (EPA) and the California Air Resources Board (CARB).
