Yamaha EF2800i 2.8KVA Inverter Generator
Yamaha EF2800i Inverter Generator
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.
