Generators can be loud and annoying - and that can be a problem whether you're at home, camping, or working on an already noisy job site. With the YG2800i, Yamaha has created the quietest generator in its class. Yamaha engineers looked at the total design and then made changes where they would be most effective — i.e., engine operating speed, intake noise, exhaust noise, and valvetrain noise. The most important addition is the "Economy Control" function. Here's how it works: Typically, a generator runs at 3600 rpm to produce 60HZ. With Yamaha's "Economy Control," the YG2800i engine speed automatically adjusts to precisely match power demand. Therefore, if you're powering only some small appliance, like a radio, drill, saw or lights, the generator runs at a low engine speed. Then, as power demand increases, the engine speed increases accordingly.

Most generators can't power anything with microcomputers or sophisticated electronics - their generated power has too many spikes and irregular wavelengths that can destroy sensitive equipment. The YG2800i sine wave is equal to or superior to commercial power. The YG2800i produces a full width sine wave, not a clipped or modified sine wave like other inverters on the market. Voltage stability is within ± 1%, and Frequency stability is ± 0.1 HZ. It's ideal for equipment and tools that requires stable frequency and voltage.
