Description

BRIGHT LIGHTS, SMALL PACKAGES. The EF2400iSHC inverter combines light weight and the latest technology to produce the highest output in its class. (source: Yamaha)

Zoom on the Yamaha EF2400iSHC

In a nutshell, the Yamaha EF2400iSHC is a quiet and compact portable inverter generator mostly geared towards:

  • Camping and tailgating hobbyists looking for a portable power source
  • Handcrafting enthusiasts who wish to work on-the-go

In the following paragraphs, we shall explore the power characteristics, available outlets, portability and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Yamaha EF2400iSHC in use

The Yamaha EF2400iSHC

The Yamaha EF2400iSHC's engine, 171 cc Yamaha MZ175 OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 2000W and reaches a peak wattage of 2400W.

Enjoying a noise rating of 53 dBA (just slightly more noisy than rainfall), this inverter generator gets running thanks to a simple traditional pull-start mechanism.

This generator features Yamaha's Smart Throttle™. This load-sensing feature automatically adjusts engine speed to match its load in order to offer greater fuel efficiency and noise reduction.

The EF2400iSHC can operate for up to 11 hours with a full tank (fuel consumption around 0.15 GPH), due to its fuel capacity of 1.6 gallon.

As the EF2400iSHC produces a clean sine wave, with a <2.5% Total Harmonic Disruption (THD), sensitive electronics may be plugged in the AC outlets safely.

Outlets

The control panel features the upcoming 2 AC outlets:

Duplex 120V 20A (5-20R)

In addition, it provides 1 DC outlet: there's a 12V 8A receptacle allowing you to easily charge your batteries.

Portability

Since the Yamaha EF2400iSHC is an inverter generator, its closed design (L20.8 x W16.5 x H18.2 in) has an esthetical advantage over conventional, open frame devices. This type of design is the most modern and convenient way to recreationally generate power.

The 75 lbs of the EF2400iSHC's dry weight enables you to use it anywhere you will ever need. Moreover, the convenient double handle greatly enhances the grip, making displacing the EF2400iSHC from A to B always an easy task.

Features

Panel of the Yamaha EF2400iSHC

The EF2400iSHC's control panel

The light indicators show you if the generator is on overload, its oil levels are insufficient and the generator is ready.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the inverter generator.

As for its security measures, the device features an automatic low oil shut-off (Oil Watch system) and an overload protection (circuit breaker), letting you use it with a peace of mind.

Yamaha's Oil Watch warning system gives you an extra peace of mind. This feature enhances long-term durability by preventing engine damage and costly repairs. Once the oil begins to run low, the generator automatically shuts off and cannot be re-started until oil is added.

Besides the usual set of documentation and user manual to get you promptly started, Yamaha also included a battery charging cables in the EF2400iSHC's packaging.

Emissions

The Yamaha EF2400iSHC is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor and thus, may be used in forested areas.

The Yamaha EF2400iSHC versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Yamaha EF2400iSHC compare to generators of similar power (between 1500 and 2500 W).

  • A weight of 75 lbs makes the Yamaha EF2400iSHC one of the heavier devices in the 1500-2500 rated wattage range. If you are concerned by weight, one of the champions in the above mentioned power range is the WEN 56202i, with a dry weight of just 38.6 pounds.
  • With a lowest possible noise of 53 dBA, this inverter generator places itself amongst the more quiet of the products delivering similar power. If noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU2200i with only 48 dBA.
  • The EF2400iSHC, offering a run time of up to 11 hours with a full tank at a 25% load, falls within the average autonomy range when compared to its peers. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Westinghouse WGen2000, boasting with up to 26 hours.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. In fact, this inverter generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 25% load is around 0.15 GPH. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Predator 2000. With a fuel consumption of as little as 0.08 GPH, it is one of the most efficient generators currently on the market.
According to our stats, the following comparison is pretty popular: Yamaha EF2400iSHC vs Yamaha EF2000iSv2.

Price comparison

As you can see from this dynamic chart, when compared to other 1500-2500W generators, the Yamaha EF2400iSHC is on the expensive side of the price range.

While certainly not the cheapest of its kind, purchasing it would most likely also mean enjoying the reliability of a high-end product.

The bottom line

STRENGTHS:
  • Inverter
  • Quiet for its power (53 dBA)
AVERAGE SPECS:
  • Decent run time
WEAKNESSES:
