Zoom on the Yamaha EF5500D

In summary, the Yamaha EF5500D is a portable generator especially useful for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Professionals who want to ensure that a power failure will not prevent them from working

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 EF5500D in use

The Yamaha EF5500D

The Yamaha EF5500D's engine, 358 cc Yamaha MZ360 OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 4500W and reaches a peak wattage of 5500W.

Enjoying a noise rating of 74.1 dBA (just slightly more noisy than a vacuum cleaner), this generator gets running thanks to a simple traditional pull-start mechanism.

With a full tank, the EF5500D can operate for around 13.5 hours at 50% load (fuel consumption around 0.51 GPH), thanks to its fuel capacity of 6.9 gallons.

Outlets

The control panel features the upcoming 6 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle

This Yamaha generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through an L5-30P to TT-30R adaptor. Besides, due to the featured twist-lock L14-30R receptacle, the EF5500D is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

The design of the Yamaha EF5500D is a typical, open frame, with the dimensions of L29.1 x W29 x H31.5 in, offering support and stability and enabling the possibility of raising it above ground level. The device has been designed for tough environments and demanding outdoor use.

As the generator's weight is 216.1 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). Still, once it is on the ground, its wheel kit and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

A lift hook located on the top of the frame offers an additional safety feature while facilitating the transport, loading and unloading of the generator.

Features

The EF5500D's control panel

Monitoring of the EF5500D's status and activity is made possible by a digital data center, which provides information on the voltage and lifetime run hours and is one of the features of its control panel.

In addition to this info, a light indicator shows you if its oil levels are insufficient.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

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.

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).

Besides the usual set of documentation and owner's manual (opens in a new tab) to get you promptly started, Yamaha also included a tool kit in the EF5500D's packaging.

Emissions

The Yamaha EF5500D 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 therefore, can be used in forested areas.

The Yamaha EF5500D versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Yamaha EF5500D compare to generators of similar power (between 4000 and 5000 W).

  • A weight of 216.1 lbs makes the Yamaha EF5500D one of the heavier devices in the 4000-5000 rated wattage range. If weight matters to you, one of the champions in this power range is the Pulsar PG5250 with only 99.5 pounds.
  • Among the generators of a comparable running wattage, this generator with a lowest noise of 74.1 dBA can be judged as noisy. For those who are looking for a less noisy device, we suggest the Yamaha EF4500iSE. With just 58 dBA, it is one of the most quiet devices in this power range.
  • As the EF5500D features an autonomy of around 13.5 hours at 50% load, it has a higher run time than an average generator of its power range. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Dewalt DXGN4500, as it provides around 15 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. Standing at an estimated 0.51 GPH (gallon per hour) at a 50% load, this generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Pulsar PG5250B. With a fuel consumption of as little as 0.33 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this interactive chart, when compared to other 4000-5000W generators, the Yamaha EF5500D is on the average side of the price range.

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