Zoom on the Yamaha EF6300iSDE
In a few words, the Yamaha EF6300iSDE is a quiet portable inverter generator perfectly suited for:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- People occasionally participating in sporting competitions, open-air performances and outdoor festivals
- Food truck owners who do not wish to see their business interrupted under any circumstances
- 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, and the extra features it benefits from.
Power & Run Time
The Yamaha EF6300iSDE
The Yamaha EF6300iSDE's engine, 357 cc Yamaha MZ360 OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 5,500W and reaches a peak wattage of 6,300W.
Operating with a noise level of 58 dBA (less noisy than a conversation at home), the inverter generator starts up via an intuitive and practical 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.
Equipped with a 4.5 gallons fuel tank, the EF6300iSDE ensures continuous operation for up to 13.3 hours with a full tank (fuel usage approximately 0.34 gallons per hour).
Featuring a <4% Total Harmonic Distortion (THD), the EF6300iSDE delivers a clean sine wave, guaranteeing the safety of your sensitive electronics plugged into its AC outlets.
Outlets
The control panel provides the upcoming 4 AC outlets:
This Yamaha generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready. Besides, as the EF6300iSDE holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home during a power outage.
Portability
As the Yamaha EF6300iSDE is an inverter generator, its encased design (L30.7 x W24.3 x H27.2 in) offers more aesthetics than a conventional, open frame product. The featured design follows the latest trends and is ideal for easy and recreational use.
While weighing 216 lbs, the generator is classified as 'portable,' indicating its mobility, albeit its heftiness may limit portability in specific situations. 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
Featuring a digital data center on its control panel, the EF6300iSDE offers you convenient access to essential information about the lifetime run hours and power output, facilitating effective monitoring of its activity and status.
In addition to this info, light indicators on the device will notify you if the oil level is too low, the generator is on overload and the generator is ready.
The inverter generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
From a security point of view, the generator is equipped with an automatic low oil shut-off (Oil Watch system) and an overload protection (circuit breaker), giving you a peace of mind during use.
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.
Accessory-wise, along with the previously mentioned features, the Yamaha EF6300iSDE is packaged with the standard documentation and an owner's manual (opens in a new tab), helping you start the device right away. An official storage cover is available, as a separate purchase.
Product Videos
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 inverter generators of similar power (between 5000 and 6000 W).
- A weight of 216 lbs makes the Yamaha EF6300iSDE one of the heavier inverters in the 5000-6000 rated wattage range. If weight is a key factor for your needs, the Pulsar PGX60BiSRCO is noteworthy for being one of the top contenders in this power range, with a dry weight of 93.5 pounds.
- Since this inverter generator is rated for a lowest possible noise of 58 dBA, it can be considered as one of the more quiet of the products generating 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.
- Autonomy-wise, with up to 13.3 hours on a full tank at a 25% load, the EF6300iSDE is on the low end when compared to other inverter generators of a similar power output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Champion 201532, boasting with up to 18 hours.
- Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. When it comes to fuel efficiency among generators with similar wattage, this inverter generator lags behind, with a consumption rate of 0.34 GPH at a 25% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.19 GPH, the DuroMax XP7000iHT is a device you could look out for.
The bottom line
- CO sensor
- GFCI Outlets
- Electric start
- Inverter
- Quiet for its power (58 dBA)
- Made in Japan
- No recoil back-up
- No remote start
- No parallel ports
- On the heavy side (216 lbs)
- Relatively low run time
- Low fuel efficiency

User Reviews
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.
