Description

The Yamaha EF3000iSEB is one of the most technologically advanced inverter generators available. Get that extra “boost” of power to get your power tool or air conditioner started quickly and efficiently thanks to the EF3000iSEB generator from Yamaha. The “B” on EF3000iSEB means it features Yamaha Boost Technology®, which provides additional power when you need it. Perfect for the RV enthusiast, the EF3000iSEB is an ideal source of power for either a fifth wheel or travel trailer. The Boost Control Unit in the generator automatically senses when you need additional boost and uses power from the internal 12-volt battery to produce additional amperage. With the additional 10-second boost, the power is comparable to a conventional 3500-watt generator. (source: Yamaha (opens in a new tab))

Zoom on the Yamaha EF3000iSEB

In a nutshell, the Yamaha EF3000iSEB is a quiet portable inverter generator mostly geared towards:

  • Handcrafting enthusiasts who wish to work on-the-go
  • Homeowners in need of an emergency backup power for their essentials
  • Camping and tailgating hobbyists looking for a portable power source
  • RV travellers wishing to enhance their freedom and nomad lifestyle

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 EF3000iSEB in use

The Yamaha EF3000iSEB

The Yamaha EF3000iSEB's engine, 171 cc Yamaha MZ175 OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 2800W and reaches a peak wattage of 3500W.

At a noise rating of 53 dBA (just slightly more noisy than a conversation at home), this inverter generator can be started via a simple traditional pull-start mechanism, or 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 full tank, the EF3000iSEB can operate for up to 18.6 hours (fuel consumption around 0.18 GPH), thanks to its fuel capacity of 3.4 gallons.

Sensitive electronics can be safely plugged in the AC outlets, as the EF3000iSEB produces a clean sine wave, with a <3% Total Harmonic Disruption (THD).

Outlets

The control panel includes the following 3 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (L5-30R) receptacle

Even if this Yamaha generator isn't quite RV Ready, it still allows for an easy RV connection via an L5-30P to TT-30R adaptor, thanks to its L5-30R receptacle.

Portability

The Yamaha EF3000iSEB's characteristic encased inverter generator design (L26.8 x W17.5 x H21.9 in), provides an esthetical advantage over any ordinary, open frame product. The generator has a contemporary design, convenient for recreationally generating power.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 154.3 lbs. However, its challenging mobility is solved by its set of 4 wheels and its double handle, which will ease its displacement, once it is on the floor.

Features

Panel of the Yamaha EF3000iSEB

The EF3000iSEB's control panel

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

Thanks to a built-in fuel gauge, the inverter generator allows you to quickly, conveniently and easily check the gas level at a glance.

As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off (Oil Watch system), 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.

It also includes a carbon monoxide sensor. This sensor is designed to monitor the level of carbon monoxide present during the generator's operation. If the generator is positioned incorrectly and carbon monoxide levels rise to an unsafe level, the generator will automatically shut down. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).

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.

Emissions

The Yamaha EF3000iSEB is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 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 inverter generators of similar power (between 2500 and 3500 W).

  • Considering its dry weight of 154.3 pounds, the Yamaha EF3000iSEB is one of the heavier inverter generators producing between 2500 and 3500 running watts. If weight is your top priority, one of the champions in this power category is the Genmax GM3300i, weighing just 47.4 pounds.
  • At a lowest noise rating of 53 dBA, this inverter generator is one of the quieter devices of similar type and power. For those who are looking for a less noisy device, we suggest the Honda EU3000iS. With just 50 dBA, it is one of the most quiet devices in this power range.
  • 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 inverter generators of a comparable output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Champion 200914, as it provides 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 fuel consumption is your top priority, we suggest to check out the Energizer eZV3500P, which has a fuel consumption of only 0.13 GPH and thus, is one of the most efficient devices in our database.

Price comparison

As you can see from this interactive chart, when compared to other 2500-3500W inverter 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.
