The OHV engine provides excellent heat dissipation for long life. View larger.
Powerful Inverter System Delivers Cleaner Electricity
The EF2400iS is built around an innovative inverter system, which is able to deliver higher-quality, cleaner electricity than competing generators. It produces energy in the form of pure sine waves, which are cleaner and more reliable than most commercial power sources.

In simpler terms, this means that you'll be able to confidently power delicate machinery, such as products with built-in microcomputers or microcomputer-controlled electric tools, without having to worry about the damage caused by unrefined energy. An electrical overload breaker is also included, to prevent generator damage in case of an unexpected overload.

Detachable side panels allow for easy maintenance.
Smart Technologies for Optimal Fuel Efficiency
The EF2400iS is exceptionally fuel efficient, able to run for up to 8.6 hours without refueling when in Economy mode. Its OHV engine runs reliably and dissipates heat efficiently, allowing for both a long life and optimal fuel consumption.

With its Smart Throttle Load feature, the generator is able to dynamically adjust engine speed depending on output, resulting in greater overall fuel efficiency. The generator also features an exclusive multipole alternator, which has a light, compact design with a great power-to-weight ratio for fuel economy.

Ergonomic, User-Friendly Design
Featuring a die-cast aluminum frame, the EF2400iS weighs only 70 pounds. It is ultra-portable and features comfort-grip handles and an easy-to-carry design. It has a convenient, centralized control panel, which allows you to easily access all of the generator's features at the push of a button. It also starts up responsively due to its auto-decompression system, which reduces compression and makes startup less difficult.

TwinTech technology allows you to hook up two units for 4,600 watts of power. View larger.
For added convenience, the EF2400iS is able to recharge batteries with its 8A12V DC output (cables included), making it ideal for RV, auto, and boat owners. You can even hook up two EF2400iS units for 4,600 watts of maximum power, thanks to TwinTech technology. And you won't have to worry about engine damage due to low oil levels: an oil-watch warning system constantly monitors oil levels and lets you know when an oil change is needed. For further convenience, you can even gauge the fuel level without opening the cap and a gasoline petcock helps prevent carburetor contamination during storage.

Noise Reduction for Quiet Operation
The EF2400iS uses sound reduction technologies to ensure the quietest operation possible. Featuring a special sound-blocking design, the generator has noise-absorbing glass wool construction, which helps dampen noise even during heavy operation. And along with the EF2400iS' super-quiet muffler with USFS-approved Spark Arrestor, as well as vibration-isolating feet, this generator keep noise at a minimum (53 to 58 dBA).

The EF2400iS is backed by a two-year warranty.
