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. |
