2.4 kW inverter generator

MODEL NO.
EF2400iS

A 2.4kVA petrol powered inverter generator, the EF2400iS has that little extra grunt, but still as quiet as ever.  Using Inverter technology, the EF2400iS is our best seller for caravans, RVs and motor homes.  Light and super quiet, it produces a massive 2400 watts of maximum power so you can run anything from a small air conditioner, refrigerator, kettle, toaster or small heater – not to forget your sensitive electronic equipment such as phones, laptops and computers.

 This unit is the lightest in its class and has two handles for easy lifting so you don’t have to break your back! Not only that, it’s also currently the most compact unit in its class on the market so it’ll fit in most caravan storage boxes.

 A dust cover and transportation kit is also available as optional extras, as well as TwinTech Parallel Use function - for almost double the power when connecting two EF2400iS together!

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.

Smart Throttle
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.
