In a nutshell, the Yamaha EF6300iSDE is a quiet portable inverter generator mostly geared towards:
- RV travellers who wish to upgrade their experience to another level
- People occasionally participating in sporting competitions, open-air performances and outdoor festivals
- Food van owners who know that just a short power outage could lose them hundreds of dollars
- 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
- Professionals in need of safely powering high-intensity work or lighting equipment
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 EF6300iSDE
The Yamaha EF6300iSDE's design includes a gasoline-fueled 357 cc Yamaha MZ360 OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 5500W and also a peak wattage of 6300W.
The inverter generator is rated for a noise of 58 dBA (less noisy than a quiet suburb). Its starting mechanism is based on a simple and elegant electric starter (battery included). The EF6300iSDE can also be remotely started, offering further convenience (separate purchase).
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 4.5 gallons, the EF6300iSDE may run for up to 13.3 hours with a full tank (fuel consumption around 0.34 GPH).
Delicate electronics can be plugged in an AC outlets safely, as the EF6300iSDE generates a clean sine wave, reaching a <4% Total Harmonic Disruption (THD).
Outlets
The control panel provides the upcoming 4 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, because the EF6300iSDE is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.
Portability
Thanks to its closed inverter generator design (L30.7 x W24.3 x H27.2 in), the Yamaha EF6300iSDE, is more esthetical than a typical, open frame generator. This type of design is the most modern and convenient way to recreationally generate power.
Although this generator is technically considered 'portable' (in the sense that it can be moved), its 200 lbs make it incredibly difficult to manually lift and transport. 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
The EF6300iSDE's control panel
Monitoring of the EF6300iSDE's status and activity is made possible by a digital data center, which provides information on the lifetime run hours and is one of the features of its control panel.
In addition to this info, the light indicators show you if the generator is ready, the oil level is too low and the generator is on overload.
The inverter 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.
Along with the aforementioned features, from an accessory standpoint, the Yamaha EF6300iSDE'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 EF6300iSDE is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
However, it features a spark arrestor and thus, may be used in forested areas.

The Yamaha EF6300iSDE versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Yamaha EF6300iSDE compare to generators of similar power (between 5000 and 6000 W).
- With its weight of 200 lbs, the Yamaha EF6300iSDE is one of the heavier generators in the 5000-6000 rated wattage category. If you are concerned by weight, one of the champions in the above-mentioned power range is the WEN GN6000, with a dry weight of just 119 pounds.
- At a lowest noise rating of 58 dBA, this inverter generator is one of the quieter devices of similar power. If noise emissions are one of your priorities, you may be interested in the Honda EU7000iS, one of the least noisy generators similarly powerful as this one, rated for 52 dBA.
- As far as autonomy is concerned, providing up to 13.3 hours of runtime with a full tank at a 25% load, the EF6300iSDE falls into the low end in comparison with other devices of a comparable power output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Westinghouse WGen5300DFv, boasting with up to 20 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 inverter generator reaches an estimated fuel consumption of 0.34 GPH (gallon per hour) at a 25% load, making it average, for the previously mentioned wattage range. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse WGen5300DFv. With a fuel consumption of as little as 0.24 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 5000-6000W generators, the Yamaha EF6300iSDE 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.

Couldn't find the right answer for you? Ask your own question.
I bought two of these generators ELEVEN years ago. I only run non ethanol premium in them. This gas is replaced every June. I keep full synthetic oil in the crankcase. I will run these generators at 30% load for one hour about once every three months. I clear the carbs of fuel before storing. These generators look, start, run and perform just like new. The ONLY issue I have had is that the onboard battery will not survive the 12 volt DC parasitic drain within a month. I have to remove both batteries from these generators and keep them on a battery tender.
These two generators were a significant investment to make eleven years ago but I do not regret it to this day. Also, they are still holding at the same retail price I paid at that time.
