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 s first inverter type generator we created one of the quietest generators in its class.
Our 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 which allows the engine speed to automatically change to match power demand The EF2800i breaks new ground in the weight per output department tipping the scales at just 29.1 kilos It's the lightest generator in its class The key is its multi-pole 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 The EF2800i s inverter system features Pulse Width Modulation PWM so wavelength distortion is less than 2.5 percent making it ideal for equipment that requires stable frequency and voltage.
