Zoom on the Yamaha EF3000iSEB
In a nutshell, the Yamaha EF3000iSEB is a quiet portable inverter generator mostly geared towards:
- Amateur DIY lovers
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- Camping and tailgating hobbyists looking for a portable power source
- RV travellers who wish to upgrade their experience to another level
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.
Power & Run Time
The Yamaha EF3000iSEB is powered by a 171 cc Yamaha MZ175 OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 2800W as well as a peak wattage of 3500W.
With a noise rating of 53 dBA (just slightly more noisy than rainfall), the inverter generator features a conventional pull-start mechanism, but also a convenient and easy-to-use electric starter (battery included).
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 3.4 gallons, the EF3000iSEB may run for up to 18.6 hours with a full tank (fuel consumption around 0.18 GPH).
As the EF3000iSEB produces a clean sine wave, with a <3% Total Harmonic Disruption (THD), sensitive electronics may be plugged in the AC outlets safely.
The control panel provides the upcoming 3 AC outlets:
Additionally, it features 1 DC outlet: there's a 12V 12A receptacle allowing you to easily charge your batteries.
This Yamaha generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready.
The Yamaha EF3000iSEB is an inverter generator and has an encased design of the following dimensions: L26.8 x W17.5 x H21.9 in. Thus, it is more aesthetical than conventional, open frame products. This modern design aims to provide an ideal power solution to recreational users.
Since the generator weighs 154.3 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). Nevertheless, it can still be moved quite conveniently with the help of its set of 4 wheels and its double handle, once it is placed on the ground.
Several light indicators serve to show you when its oil levels are insufficient, the generator is ready and the generator is overloaded.
The inverter generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off (Oil Watch system), giving you a peace of mind during use.
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 EF3000iSEB's box includes the typical documentation and an owner's manual (opens in a new tab), which will help you start your generator promptly.
The Yamaha EF3000iSEB 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, which makes it suitable for use in forested areas.
The Yamaha EF3000iSEB versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Yamaha EF3000iSEB compare to generators of similar power (between 2500 and 3500 W).
- At a dry weight of 154.3 pounds, the Yamaha EF3000iSEB is one of the heavier devices which can produce between 2500 and 3500 running watts. In terms of weight, one of the champions in their power range is the Generac GP3300i, standing at just 59.5 lbs.
- With a lowest possible noise of 53 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 EU3000iS, whose lowest noise levels reach just 50 dBA.
- Since the EF3000iSEB boasts with a run time of up to 18.6 hours at 25% load, it can be safely judged as a device of a higher run time than most generators of a comparable output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Champion 200954, reaching up to 22 hours.
- Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. This inverter generator has an average fuel consumption among comparably powerful devices, as it reaches 0.18 GPH (gallon per hour) at a 25% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Energizer eZV3500P. With a fuel consumption of as little as 0.13 GPH, it is one of the most efficient generators currently on the market.
Here's a list of the most popular specific comparisons:
As you can see from this interactive chart, when compared to other 2500-3500W generators, the Yamaha EF3000iSEB 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
- Electric start
- Quiet for its power (53 dBA)
- High run time
- Decent fuel efficiency
- On the expensive side
- No data center
- No remote start
- No parallel ports
- On the heavy side (154.3 lbs)
