Generators can be loud and annoying — and that can be a problem
whether you're providing backup power at home, camping in the
wilderness, or working on the job site. With the EF2800i, Yamaha
has created one of the most quiet generators in its class. The
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 something we call "Economy Control." Here's
how it works: Typically, after starting a generator — as it's
generating power —
the generator operates at a constant rpm to produce
peak power. This is usually the loudest noise level. With "Economy
Control," the engine speed automatically changes to match power
demand. Therefore, if you're powering only some small appliance or
lights, the generator runs at a low engine rpm. Then, as power
demand increases, the engine revs up accordingly. |

It's not uncommon to have generators weighing over 120 lbs. And
weight usually corresponds to power output. That is, until Yamaha
created the EF2800i. Tipping the scales at just 64 lbs., it's the
lightest generator in its class. The key is its multipole rotor
with a small stator and Pulse Width Modulation inverter. This
design is smaller and lighter than a conventional two-pole
alternator and large stator — and it makes the EF2800i extremely
portable.

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 EF2800i — with its inverter system — features Pulse
Width Modulation (PWM) so wavelength distortion is less than 2.5
percent — it's ideal for equipment that requires stable frequency
and voltage.
