Description
Zoom on the Yamaha EF2000iSHv2
In summary, the Yamaha EF2000iSHv2 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
- Handcrafting enthusiasts who wish to work on-the-go
In the sections ahead, the power characteristics, availability of various outlets, the portability and any additional features of the device shall be discussed, including its emission compliance information.
Power & Run Time
The Yamaha EF2000iSHv2
The Yamaha EF2000iSHv2's core is the 79 cc Yamaha MZ80 OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 1600W and a peak wattage of 2000W. Moreover, since it is parallel capable (Twin Tech cable not included), its power may be doubled if linked to a second compatible unit.
The inverter generator features a simple traditional pull-start mechanism. It is rated for a noise of 51.5 dBA (just slightly more noisy than a conversation at home).
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.
As the EF2000iSHv2 produces a clean sine wave, with a <2.5% Total Harmonic Disruption (THD), sensitive electronics may be plugged in the AC outlets safely.
- For camping/tailgating: 1 DVD player, 1 slow cooker, 1 satelite receiver, 1 mixer, 1 radio and 1 cell phone charger
- At home: 1 DVD player, 1 slow cooker, 1 satelite receiver, 1 mixer, 1 radio and 1 cell phone charger
- For work: 1 drain cleaner, 1 electric fence (25 miles) and 1 bug zapper
Outlets
The control panel includes the following 2 AC outlets:
It also sports 1 DC outlet: there's a 12V 8A receptacle with which you may charge your batteries with ease.
Portability
The Yamaha EF2000iSHv2's characteristic encased inverter generator design (L19.3 x W11 x H17.9 in), provides an esthetical advantage over any ordinary, open frame product. This modern design aims to provide an ideal power solution to recreational users.
The EF2000iSHv2 is a lightweight, portable generator, as it only weighs 44.1 lbs. A single person should not have any problems moving it around and thus, enjoy power availability on-the-go. It can also be carried without effort with a featured handle (molded in the case), further improving its convenience.
Features
The device’s light indicators will display if the generator is ready, its oil levels are insufficient and the generator is overloaded.
The inverter generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.
Security-wise, this product benefits from an automatic low oil shut-off (Oil Watch system) and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.
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.
As for its accessories, apart from the previously mentioned features, the Yamaha EF2000iSHv2 also comes with the basic documentation and a user manual, allowing you to start it right away.
Emissions
The Yamaha EF2000iSHv2 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, so it is adequate 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).
- Weight-wise, the Yamaha EF2000iSHv2 has only 44.1 lbs, which renders it one of the lighter generators which produce 1500 to 2500 rated watts. Regarding dry weight, one of the champions in the same power range is the WEN 56202i, with a dry weight of only 38.6 lbs.
- 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. For those who are looking for a less noisy device, we suggest the Honda EU2200i. With just 48 dBA, it is one of the most quiet devices in this power range.
- The EF2000iSHv2, offering a run time of 10.5 hours with a full tank at a 25% load, falls within the average autonomy range when compared to its peers. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Westinghouse WGen2000, reaching 26 hours.
- While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. This inverter generator, with an estimated fuel consumption of just 0.1 GPH (gallon per hour) at 25% load, is one of the more fuel efficient generators, for the previously mentioned wattage range. If fuel consumption is your top priority, we suggest to check out the Energizer eZV2000P, which has a fuel consumption of only 0.08 GPH and thus, is one of the most efficient devices in our database.
Price comparison
As you can see from this dynamic 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.
The bottom line
- Parallel capable
- Inverter
- Lightweight (44.1 lbs)
- Quiet for its power (51.5 dBA)
- Fuel efficient
- Decent run time
- On the expensive side
- No data center
- No electric start
