Main Features of The Yamaha EF2400iSHC

Now that we’ve covered a little bit of background on the Yamaha EF2400iSHC 2400 watt inverter generator, let’s see what’s under the hood and dive into the main features of this portable inverter.


First off, one of the best features of using an inverter compared to a generator, is the model’s ability to match power output. This means engine speed is adjusted to match your needs at that moment.

Yamaha’s innovative, Smart Throttle technology automatically adapts to accommodate a variety of power needs.

If you’re using the Yamaha EF2400iSHC inverter to power lights, the output will be constant. But let’s say you’re operating a pressure washer, the inverter will spike in RPMs to keep up with the power demands when the pressure washer throttle is used.

This creative design contributes towards an ultra quiet unit that’s geared for maximum fuel efficiency.

With only 1.6 gallons of unleaded gas, the Yamaha inverter can run for up to 8.6 hours at ¼-capacity load.


Another benefit integrated within the Yamaha EF2400iSHC generator is its user friendly, easy to manage design.

Constructed from an Aluminum die-cast frame, and fashioned with a lightweight flywheel and Aluminum TCI rotor, worrying about heavy lifting is a thing of the past.

Overall, this Yamaha EF2400iSHC inverter generator weighs 75 lbs. (dry) and is equipped with two carrying handles on top of the frame.


The design team at Yamaha did their part to ensure you receive the best when the topic turns to power output.

Don’t be fooled by its size, the Yamaha EF2400iSHC generator is a beast of a little inverter. The 171 cc, 5.5 HP, air-cooled OHV 4-stroke motor is plenty powerful and possesses High Current delivery.

As Yamaha states, “the High Current model starts most high efficiency 13,500 btu AC in temperatures up to 110° F.”


Lastly, this Yamaha used Pulse Width Modulation (PWM) to yield high-quality power to all electronics, similar to as if you were at home.

Due to this high-tech technology, users can use the Yamaha EF2400iSHC 200 watt inverter generator with any microprocessor device or appliance in full confidence.

What is the difference between inverter and generator?

More often than not, the term generator is with or as inverter, but the two models vary in a number of ways. But let’s be clear, an inverter and a generator deliver the same result and that’s why they’re commonly used together.

The main difference is generators consume raw power from the alternator while inverters recycle and clean the power for immediate use.

Generators tend to weigh more while inverters are easier to manage and transport.

Generators operate at a near constant cycling rate, yet Yamaha EF2400iSHC inverters match motor RPMs to the power needed – ‘when demand for power goes up, engine speed increases.’
