Honda EU3000iS vs Yamaha EF3000iSEB

Inverter generator is an advanced technology replacing the generators which is labeled as noisy and bulky tools. Inverter generators change all the notions that people have of generators as it is smaller, quieter, and also quiet light. DC power is transformed to AC power with high frequency is how the inverter generators work. The power that an inverter generator provides is stable and adequate to power all your household appliances, from your delicate flat-screen television and fridge to your computer and other devices. There are many types and brands of inverter generator on the market today. Let us take a closer look at two inverter generators, which are Honda EU3000iS and Yamaha EF3000iSEB.

Power & Run Time

The Honda EU3000iS has an 196 cc Honda GX200 OHV 4-stroke engine, fueled by gasoline and can deliver 120V while the Yamaha EF3000iSEB has an 171 cc Yamaha MZ175 OHV 4-stroke engine also fueled by gasoline and can provide 120V. A running wattage of 2800 W along with a peak wattage of 3500W is delivered by the Yamaha, the Honda also provides the same running wattage but a difference in peak wattage at 3000W.

The noise rate for EF3000iSEB is 53 dBA, whereas the EF3000iS is quieter at only 50dBA. Both of these inverter generators can be started via a conventional pull-start mechanism but a simple and elegant electric starter is available, and both are battery included. These two inverter generators have a fuel capacity of 3.4 gallons, where Honda can run up to 20 hours with a full tank and up to 18.6 hours with a full tank for Yamaha. Fuel consumption is around 0.18 GPH for Yamaha and 0.17 GPH for Honda.

The Yamaha generates a clean sine wave reaching <3% Total Harmonic Disruption (THD), Honda also offers the same. This means that delicate electronics can be plugged in an AC outlets safely.

3 AC outlets for the EU3000iS are Duplex 120V 20A (5-20R) and 120V 30A (L5-30R) receptacle, in addition to 1 DC outlet of 12V 12A receptacle which you may charge your batteries with ease. Yamaha control panels include the same outlets as the Honda, both generators are not RV ready but thanks to its L5-30R receptacle allows an easy RV connection via an L5-30P to TT-30R adaptor.


The Yamaha EF3000iSEB dimensions are L26.8 x W17.5 x H21.9 and weighs 154.3 lbs. Even though this is a portable inverter generator without special equipment can be a challenge however there is a wheel kit and its double handle so the generator can be easily moved, once placed in the ground.
The Honda EU3000iS dimensions are not far from the Yamaha with L25.9 x W17.6 x H22 but it weighs lighter at only 131 lbs. Unfortunately with its weight it may be challenging to be considered portable, since it doesn’t have a wheel kit like the Yamaha.


If the generator is on overload, the oil level is too low and the generator is ready can be shown through the light indicators that are available for these two types of inverter generator. A built-in fuel gauge is provided by these two generators for an easy check on the gas level. Like most generators on the market today, both Yamaha and Honda are equipped with an automatic low oil shut-off (oil watch system) and an overload protection (circuit breaker).

The Yamaha Oil Watch warning system 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.

The Honda is parallel capable so its power may be doubled if linked to a second compatible unit even though the parallel cables are not included. Sadly, the Yamaha is not parallel capable so we can not add extra power when needed. Both generators feature a spark arrestor so it is adequate for use in forested areas.

Honda EU3000iS vs Yamaha EF3000iSEB

- Popular model can operate a wide variety of appliances, including a furnace, fridge, microwave, TV, blenders, most 13,500 BTU RV AC units and much more
- Super quiet: so quiet, your neighbors will thank you; the EU3000is operates at 49 to 58 dB (A), which is less noise than a normal conversation
- Fuel efficient runs up to 20 hours on 3.4 Gal. of fuel: thanks to our exclusive eco-throttle, the EU3000 is offers great fuel efficiency
- Advanced inverter technology - reliable power for computers and other sensitive equipment: Honda's inverter technology means stable
- The Boost Control Unit (BCU) senses when extra power is needed and boosts output for up to 10 seconds
- Sound absorbing material, used in key locations, does not resonate sound. Newly designed muffler and molded fan produce unbeatable noise reduction
- Greater fuel efficiency and noise reduction by automatically adjusting engine speed to match the load
- Continuous operation for up to 19 hours without refueling


Altogether the Honda EU3000is and Yamaha EF3000iSEB have many things in common. But if we look more closely, both the Yamaha and Honda share the same running wattage of 2800W, they will simultaneously power the same appliances. However, the Yamaha EF3000iSEB will give more power to start the appliances with 3500W since it requires an additional boost to get their motor running. The Honda EU3000is offers a higher runtime and more fuel efficiency, since it can operate up to 20 hours and a 0.17 GPH gasoline consumption. While the Yamaha only offers a maximum runtime of 18.6 hours with a 0.18 GPH gasoline consumption.

If you take noise emission seriously then the Yamaha is not your choice since it has a 53 dBA noise rate when Honda offers a quieter option at 50 dBA. Both generators share the same overall bulk so neither of them will take up less storage space. Even if the Honda is somewhat lighter at 131 lbs but the Yamaha benefits from its wheel kit, which can help the generator to be easily moved. Yamaha and Honda have a double handle, which improves your grip when you wish to move them around.

Both generators offer a low THD, this means it is perfectly suitable to safely power your sensitive electronic devices. As has been discussed above, both devices can be started either via a pull-start mechanism or an electric starter. These generators are covered under a warranty for up to 3 years. In the end, the Honda EU3000is and Yamaha EF3000iSEB came to a draw. It is up to you to choose the generator where the specification fits your needs.
