The Yamaha EF2800i Inverter Generator is the lightest and quietest generator in its class. The EF2800i is able to power anything from power tools to sophisticated electronics including laptops, tablets and computers.
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.
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.
Please Note: This Yamaha generator does not come with oil required to operate it. We are unfortunately unable to ship this online due to it being dangerous goods, but it can be easily found in your local hardware/auto parts store.

What is an Inverter System?
An inverter system stabilizes the amount of voltage and frequency produced by a petrol engine driven alternator through the supply of "sine wave" electricity, with a distortion ratio of less than 3%. That's why Yamaha Inverters are the ideal power source when using precision equipment or micro-computer controlled electrical appliances.
More Controlled, Clean Power
Yamaha's Inverter system produces AC current within a controlled electrical circuit process, known as PWM (Pulse Width Modulation). As a result, fluctuations in engine speed do not affect the voltage or frequency of the electrical output while at the same time reducing output emissions.
Multi-Polar Alternator System
The adoption of a multi-polar alternator enables the generation of more efficient, high frequency 3-phase AC current that the inverter than turns into single phase. The high efficiency alternators on a Yamaha Inverter achieve a much lighter and more compact generating unit than conventional 2-pole rotor type alternators.
Yamaha's Smart throttle feature automatically adjusts the engine speed to precisely match the energy load. this means much quieter, more efficient engines that run and last longer.
Unbeatable Noise Block
Yamaha's Noise Block feature, an acoustically engineered sound reduction system , utilises various sound absorbing materials, moulded cases, an intake silencer, fibreglass insulation, plus newly designed mufflers and fans to provide virtually silent running while maintaining the highest quality performance.
Quiet Muffler & Low Oil Shut-Off
At the heart of every generator is a strong Yamaha engine that delivers powerful and consistent performance, that's so quiet you'll forget its running. Every generator includes an approved spark arrestor and a low oil shut-off system for long life and added peace of mind.
