2400 Watts or 2.4kVa Max power Output in a Quiet Portable generator suitable for both recreational and worksites.
Yamaha EF2400iS Is The Next Step Forward In Generator Technology!
The EF2400iS is a model that brings the reliable Yamaha inverter technology used on the highly acclaimed EF2800i to the 2kVA class.
When we built our latest inverter generator, we listened to exactly what our customers wanted. Not only is it super-quiet (54-59dBA @ 7m), it only weighs 32 kilos and produces 2400 watts of maximum power. Cleaner, quieter and more powerful, the EF2400iS is the next step forward in generator technology.
The EF2400iS has been built to clear the US EPA Phase II and CARB Tier II emissions standards (the world's strictest), as well as the 2002/88/EC standard of Europe and Japan's LEMA standard. What's more, this model is assembled in our factories that are certified under the ISO 9001 and 140001 standards and have eliminated use of toxic materials like cadmium, lead and sexivalent chrome in accordance with Yamaha's self-instigated regulations.
They also boast a 97.1% recycle-ability ratio, all of which adds up to make this a very environment-friendly model.
The aluminium die-cast frame and smooth, handsome lines with minimal interruptions to its flat surfaces give this model a design that is not out of place in either household or utility uses.
In addition, the design provides easy access to the oil filler cap and air filter, and easier access for oil changes and other servicing.

Parallel Use means the capacity to connect two generators of the same specification and operate them together to provide quality electricity with a max. Output of roughly double that of the single unit, while retaining the same voltage and frequency.
This function makes it possible to run appliances or loads too heavy for one generator. The EF2400iS is designed with a special Yamaha-specification cable to connect two units so they run simultaneously, to produce an electrical output of a maximum of 3.8 kVA, without any special operations or setting adjustment.
