Leave it to Yamaha to take a good thing and make it even better, like our Inverter Series of generators - bringing along a generator was never easier or quieter. We adopted inverter technology because it translates into a compact, lightweight design that makes these generators easy to transport whether you're camping, fishing, using them around the house, during a power outage, or on the job site. Plus, they're so quiet, they're less obtrusive and more suitable for a wider range of applications.

Inverter technology regulates the electrical output using Pulse Width Modulation (PWM) to produce clean, high-quality electricity. That means these generators deliver a "pure" sine wave with full width and amplitude so you can use them with confidence as a power source for computers, solid-state appliances with built-in computer functions or microcomputer-controlled power tools.

Yamaha is always pushing the technology envelope to make generators quieter and more efficient while continuing to deliver exceptional performance. The perfect example is Yamaha's new Smart Throttle feature that automatically adjusts the engine speed to precisely match the load. Smart Throttle allows the generator to run quieter while increasing fuel efficiency, lengthening engine life, and extending running time between refueling.

Generating electricity can be a noisy proposition. That's why we created Noise Block, our acoustically engineered sound reduction system. This technology utilizes various sound absorbing materials, molded cases, an intake silencer, fiberglass insulation, plus newly designed mufflers and fans to provide virtually silent running while maintaining quality performance.

Best of all, at the heart of each generator is a muscular Yamaha engine that delivers strong, consistent performance. Every generator also includes a US Forestry Service approved spark arrestor , as well as a low oil warning system for long life and added peace of mind. Yamaha Inverter generators - they're ready, willing and able to tackle the widest variety of tasks.
