It's not uncommon to have generators weighing over 120 lbs.
And weight usually corresponds to power output. Moving a generator
around a job site can be challenging. It might take 2 or 3 people
or a back hoe to move a generator from place to place on a job
site. That is, until Yamaha created the YG2800i. Tipping the
scales at just 66 lbs., it's the lightest generator in its class.
The key is its sixteen-pole rotor with twenty-four coil 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 YG2800i extremely portable around
a job site or just about anywhere.

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.
