Description
Zoom on the Yamaha EF5500DE
In summary, the Yamaha EF5500DE is a portable generator especially useful for:
- RV travellers who wish to upgrade their experience to another level
- Occasional participants of outdoor events, competitions, concerts and festivals
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- Professionals who want to ensure that a power failure will not prevent them from working
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 EF5500DE
The Yamaha EF5500DE'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.
At a noise rating of 74.1 dBA (just slightly more noisy than a dishwasher), this generator can be started via a conventional pull-start mechanism, or a convenient and easy-to-use electric starter (battery included). For additional convenience, the EF5500DE may also be remotely started (separate purchase).
With a full tank, the EF5500DE 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 following 6 AC outlets:
Even though this Yamaha generator isn't quite RV Ready, its L5-30R receptacle allows an easy RV connection via an L5-30P to TT-30R adaptor. Besides, as it features a twist-lock L14-30R receptacle, the EF5500DE is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.
Portability
The design of the Yamaha EF5500DE 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.
Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 238.1 pounds. However, this lack of maneuverability is compensated by its wheel kit and its folding handle, with which you can conveniently shift it, once it's on the ground.
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 EF5500DE's control panel
To help you monitor the EF5500DE's status and activity, its control panel is equipped with a digital data center, giving you information on the lifetime run hours and voltage.
In addition to this info, a light indicator allows you to instantly see if its oil levels are insufficient.
The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
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 EF5500DE's packaging.
Emissions
The Yamaha EF5500DE 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 and thus, may be used in forested areas.
Product Video
The Yamaha EF5500DE versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Yamaha EF5500DE compare to generators of similar power (between 4000 and 5000 W).
- A weight of 238.1 lbs makes the Yamaha EF5500DE one of the heavier devices in the 4000-5000 rated wattage range. Regarding dry weight, one of the champions in the same power range is the Pulsar PG5250, with a dry weight of only 99.5 lbs.
- If compared to generators capable of producing a similar running wattage, this generator with a lowest emitted noise of 74.1 dBA can be considered somewhat noisy. If noise emissions are one of your priorities, you may be interested in the Yamaha EF4500iSE, one of the least noisy generators similarly powerful as this one, rated for 58 dBA.
- With a run time of around 13.5 hours at 50% load, the EF5500DE has one of the higher run times, compared to its similarly powerful peers. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Dewalt DXGN4500, boasting with 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. 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 you wish to acquire one of the most gasoline efficient products of this power range, the Pulsar PG5250B, with a fuel consumption of 0.33 GPH could be in your good books.
Price comparison
As you can see from this interactive chart, when compared to other 4000-5000W generators, the Yamaha EF5500DE is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
