Description
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 outdoor fairs, festivals or events
- 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 be able to deliver results, even during a power failure
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 EF5500D
The Yamaha EF5500D's design includes a gasoline-fueled 358 cc Yamaha MZ360 OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 4500W and also a peak wattage of 5500W.
With a noise rating of 74.1 dBA (just slightly more noisy than a vacuum cleaner), the generator features a conventional pull-start mechanism.
With a fuel capacity of 6.9 gallons, the EF5500D may run for around 13.5 hours at 50% load with a full tank (fuel consumption around 0.51 GPH).
Outlets
The control panel includes the following 6 AC outlets:
While this Yamaha generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with 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 Yamaha EF5500D has the following dimensions: L21.9 x W29 x H31.5 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.
As the generator's weight is 221.7 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). Nevertheless, it can still be moved quite conveniently with the help of its wheel kit and its folding handle, once it is placed on the ground.
The generator comes with an additional safety feature, a lift hook on the top of its frame, which is helpful during its transport, loading and unloading.
Features
The EF5500D's control panel
One of the many EF5500D's features is the data center, included in its control panel, which conveniently provides information on the lifetime run hours and thus, helps you monitor its activity and status.
In addition to this info, a light indicator serves to show you when its oil levels are insufficient.
The fuel level of the 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 automatic low oil shut-off (Oil Watch system) and an overload protection (circuit breaker).
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.
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, making it usable in forested areas.
Product Video
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).
- At a dry weight of 221.7 pounds, the Yamaha EF5500D is one of the heavier devices which can produce between 4000 and 5000 running watts. If weight matters to you, one of the champions in this power range is the Pulsar PG5250 with only 99.5 pounds.
- This generator, with its lowest possible noise rated at 74.1 dBA falls into the more noisy category, compared to other devise of a similar running wattage. If you are concerned with noise, check out the A-iPower AP5000, which is one of the least noisy generators in its power range, with a noise rating of just 58 dBA.
- The EF5500D provides a higher run time than similarly powerful devices, reaching around 13.5 hours at 50% load. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Dewalt DXGN4500, which is able to run for around 15 hours.
- Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This generator has an estimated fuel consumption of roughly 0.51 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. If fuel consumption is your top priority, we suggest to check out the Pulsar PG5250B, which has a fuel consumption of only 0.33 GPH and thus, is one of the most efficient devices in our database.
The bottom line
- GFCI Outlets
- High run time
- Decent fuel efficiency
- No electric start
- On the heavy side (221.7 lbs)
- On the noisy side (74.1 dBA)
