Zoom on the Yamaha EF2000iSHv2

In a nutshell, the Yamaha EF2000iSHv2 is a quiet, compact and lightweight portable inverter generator mostly geared towards:

  • Camping and tailgating buffs looking to enhance their experience
  • 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 EF2000iSHv2 in use

The Yamaha EF2000iSHv2

The Yamaha EF2000iSHv2's engine, 79 cc Yamaha MZ80 OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 1600W and reaches a peak wattage of 2000W. Additionally, as the generator is parallel capable (Twin Tech cable (opens in a new tab) not included), it can be linked to a second unit for more power.

With a noise rating of 51.5 dBA (just slightly more noisy than a refrigerator), the inverter generator features a conventional 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.

With a full tank, the EF2000iSHv2 can operate for up to 10.5 hours (fuel consumption around 0.1 GPH), thanks to its fuel capacity of 1.1 gallon.

The EF2000iSHv2 generates a clean sine wave: providing <2.5% Total Harmonic Disruption (THD), delicate electronics can be plugged in its AC outlets safely.

Outlets

The control panel features the following 2 AC outlets:

Duplex 120V 20A (5-20R)

Furthermore, it has 1 DC outlet: there's a 12V 8A receptacle with which you may charge your batteries with ease.

Portability

Thanks to its closed inverter generator design (L19.3 x W11 x H17.9 in), the Yamaha EF2000iSHv2, is more esthetical than a typical, open frame generator. The generator has a contemporary design, convenient for recreationally generating power.

Since the EF2000iSHv2 weighs only 44.1 lbs, it can be labeled as a portable lightweight generator. The generator can be moved with ease by only one person and so it can be enjoyed on-the-go. Further convenience is provided by its handle (molded in the case), as it allows you to carry it effortlessly.

Features

Several light indicators serve to show you when the generator is on overload, its oil levels are insufficient and the generator is ready.

The fuel level of the inverter generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

From a security standpoint, the product offers an automatic low oil shut-off (Oil Watch system) and an overload protection (circuit breaker), allowing you to 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.

Along with the aforementioned features, from an accessory standpoint, the Yamaha EF2000iSHv2's box includes the typical documentation and an owner's manual (opens in a new tab), which will help you start your generator promptly. An official storage cover is available, as a separate purchase.

Emissions

The Yamaha EF2000iSHv2 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, which makes it suitable for use in forested areas.

Product Video

The Yamaha EF2000iSHv2 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Yamaha EF2000iSHv2 compare to generators of similar power (between 1500 and 2500 W).

  • As far as its dry weight is concerned, the Yamaha EF2000iSHv2 weighs just 44.1 pounds and thus, it is one of the lighter 1500 to 2500 rated wattage generators. If you are concerned by weight, one of the champions in the above mentioned power range is the Champion 200949, with a dry weight of just 38.6 pounds.
  • With a lowest possible noise of 51.5 dBA, this inverter generator places itself amongst the more quiet of the products delivering similar power. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Honda EU2200i, whose lowest noise levels reach just 48 dBA.
  • Given that the EF2000iSHv2 reaches an autonomy of up to 10.5 hours with a full tank and at 25% load, it is placed within the average autonomy range of similarly powerful generators. 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.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. At an estimated fuel consumption of 0.1 GPH (gallon per hour) at 25% load, this inverter generator is a rather fuel efficient one within its wattage category. If you wish to acquire one of the most gasoline efficient products of this power range, the Predator 2000, with a fuel consumption of 0.08 GPH could be in your good books.

Price comparison

As you can see from this interactive chart, when compared to other 1500-2500W generators, the Yamaha EF2000iSHv2 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.
