Zoom on the Yamaha EF2000iSv2

In summary, the Yamaha EF2000iSv2 is a quiet, compact and lightweight portable inverter generator especially useful for:

  • Tailgating and campground aficionados with the desire of enjoying power anywhere they go
  • DIYers who wish to improve their efficiency with tools

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 EF2000iSv2 in use

The Yamaha EF2000iSv2

The Yamaha EF2000iSv2's design includes a gasoline-fueled 79 cc Yamaha MZ80 OHV 4-stroke engine. With a 120V output, it gives a running wattage of 1600W and also 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.

Enjoying a noise rating of 51.5 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.

With a fuel capacity of 1.1 gallon, the EF2000iSv2 may run for up to 10.5 hours with a full tank (fuel consumption around 0.1 GPH).

Sensitive electronics can be safely plugged in the AC outlets, as the EF2000iSv2 produces a clean sine wave, with a <2.5% Total Harmonic Disruption (THD).

Outlets

The control panel includes the following 2 AC outlets:

Duplex 120V 20A (5-20R)

It also sports 1 DC outlet: there's a 12V 8A receptacle with which charging your batteries is made easy.

Portability

Since the Yamaha EF2000iSv2 is an inverter generator, its closed design (L19.3 x W11 x H17.9 in) has an esthetical advantage over conventional, open frame devices. This modern design aims to provide an ideal power solution to recreational users.

The EF2000iSv2 is a lightweight, portable generator, as it only weighs 44.1 lbs. The product’s power can be enjoyed on-the-go, as it can be moved by a single person without trouble. In addition, a handle (molded in the case) lets you carry it easily and further increases its convenience.

Features

Panel of the Yamaha EF2000iSv2

The EF2000iSv2's control panel

The light indicators show you if the generator is ready, the oil level is too low and the generator is on overload.

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

As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off (Oil Watch system).

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 EF2000iSv2's box includes the typical documentation and an owner's manual (opens in a new tab), which will help you start your generator promptly.

Emissions

The Yamaha EF2000iSv2 is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

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

The Yamaha EF2000iSv2 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Yamaha EF2000iSv2 compare to generators of similar power (between 1500 and 2500 W).

  • Regarding its weight, the Yamaha EF2000iSv2 only weighs in at 44.1 pounds, which means it's one of the lighter generators in the 1500-2500 rated wattage range. If weight matters to you, one of the champions in this power range is the WEN 56202i with only 38.6 pounds.
  • Since this inverter generator is rated for a lowest possible noise of 51.5 dBA, it can be considered as one of the more quiet of the products generating 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.
  • As the EF2000iSv2 offers up to 10.5 hours run time on a full tank at a 25% load, it falls within the average autonomy range among the generators of a similar power. 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. With an estimated gasoline consumption of 0.1 GPH (gallon per hour) at 25% load, this inverter generator is among the more fuel efficient of the products in the above-mentioned wattage range. If you wish to further improve in the area of fuel efficiency, the Predator 2000, which boasts with a gas consumption of only 0.08 GPH, may be the right generator for you.

Price comparison

As you can see from this interactive chart, when compared to other 1500-2500W generators, the Yamaha EF2000iSv2 is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
