Quietest 240v generators performance on a score of 10 in important categories*

*Compared to similar generators and sometimes based on customer input

1. Honda EU7000iS

The Honda EU7000iS is the quietest 240v generator with noise levels of 52 to 58 dBA at 25% to 100% load.

This 240v generator not just the quietest model in this category but also appears on many other lists of quietest generators.

One thing you do want to keep in mind is that all this silent power comes at a price that is expensive compared to most other options.

Additionally, there are a few very exceptional cases where customers have technical issues with the Honda EU7000iS.

Something else to note is that the Honda EU7000iS will “only” offer 22.9 running amps at 240 volts (and 5500 running watts).

Pros

  • Quietest 240v generator with 52 to 58 dBA (25% to 100% load)
  • Honda EU7000iS offers 7000 starting watts, 5500 running watts, 30 amps, and 240 volts
  • Parallel capability
  • Nice run time of 16 hours at 25% load
  • Should be less than 3% THD
  • Electric start
  • Honda generator brand reputation
  • Remote operation through Honda My Generator app
  • Four GFCI outlets
  • CO sensor
  • Weight of 263.2 lb (119.4 kg)
  • Relatively positive customer reviews
  • 3 years limited residential and 12 months limited commercial warranties

Cons

  • Expensive compared to other 240v generators
  • A few exceptional cases of technical difficulties

That being said, as you can see in the list of the best 240 volt generators, this model could potentially be worth it for certain people and situations.

More specifically, if you have a big budget and want a relatively reliable generator with convenient remote tracking and operation through the app, you could consider the Honda EU7000iS.

Its relatively long run time of 16 hours at 25% load can be helpful for running something like an RV AC overnight or just keeping your refrigerator going without too many refuels.

The electric start also makes it convenient to get the Honda EU7000iS going for elderly people or anyone else who wants to save their strength.

In short, the price of the Honda EU7000iS will turn many people to alternatives. However, this quiet 240v generator could potentially be worth considering in your situation.

2. Powerhorse 7500i

The Powerhorse 7500i is the best quiet 240v generator thanks to its more reasonable (but still pricey) investment requirement and power increase.

With 6500 running watts, you could get up to 27 amps at 240 volts.

And thanks to its high-capacity outlet, the Powerhorse 7500i is on the list of the quietest 50 amp generators too (but can only reach this at 120 volts).

You are likely interested in a 240 volt inverter generator to power something like an RV or camper.

Pros

  • Relatively low noise levels of 55 dBA at 25% load and 63.9 dBA at rated load
  • Powerhorse 7500i offers 7500 starting watts, 6500 running watts, 50 amps, and 240 volts
  • Good run time of 16 hours at 25% load
  • THD of 1.5%
  • Has electric start
  • Four GFCI outlets
  • Weight of 287 lb (130.2 kg)
  • Very positive customer reviews
  • 2 years limited residential and 90 days limited commercial warranties

Cons

  • Relatively short commercial warranty
  • Pricey for its power level

However, people with a food truck or on a construction site want to know that the Powerhorse 7500i only has 90 days commercial warranty.

Besides the power and convenience of the 50 amp outlet, the positivity of the Powerhorse 7500i customer reviews stands out too.

You should be able to rely on this inverter generator for powering essential devices like a refrigerator in situations like power outages.

So the Powerhorse 7500i is still a pricey investment but if you want a super quiet generator that offers 240 volts, this will often be the top option.

3. Yamaha EF6300iSDE

The Yamaha EF6300iSDE deserves its spot on the list thanks to its 240 volt outlet and noise levels of 58 to 64 dBA at 25% to 100% load.

However, it is important to note that you will likely prefer one of the other inverter generators on this list.

The first reason for this is that the Yamaha EF6300iSDE is relatively expensive. Especially considering it “only” offers 6300 starting watts and 5500 running watts.

There are also some customer reviews mentioning technical issues and challenging maintenance and navigation.

Pros

  • Relatively low noise levels of 58 to 64 dBA (at 25% to 100% load)
  • Yamaha EF6300iSDE offers 6300 starting watts, 5500 running watts, 30 amps, and 240 volts
  • Nice run time of 13.3 hours at 25% load
  • Less than 4% THD
  • Has electric start
  • Optional remote start
  • CO sensor
  • Weight of 200 lb (97 kg)
  • 3 years limited warranty

Cons

  • Expensive for its power level
  • A few exceptional cases of technical difficulties
  • Maintenance can be challenging
  • Moving the 240v generator around can be challenging

In combination with the weight of 200 pounds (97 kg), elderly people and individuals on road trips with many stops likely want to think twice before investing in the Yamaha EF6300iSDE.

Besides these details, the Yamaha EF6300iSDE is somewhat standard. At this price point, that is not a good thing.

In turn, you will likely get more value and satisfaction from one of the other 240 volt generators.

Even if you only care about noise levels.

4. Champion 201175 8500

The Champion 201175 8500 is the quietest dual fuel 240v generator on the list with 61 dBA (assuming at 25% load and 23 feet away).

This may sound somewhat louder at first. However, considering a regular conversation is around 60 decibels you can still say the Champion 201175 is relatively quiet.

Another positive point is that the 7000 running watts allow you to run 240 volt devices at 29 amps.

The convenience and capacity of the 50 amp outlet round out the Champion 201175 8500 powerhouse nicely.

Pros

  • Relatively low noise levels of 61 dBA
  • Champion 201175 8500 offers 8500 starting watts, 7000 running watts, 50 amps, and 240 volts (gasoline)
  • Dual fuel means generator can run on propane (LPG) too
  • Run time of 14 hours at 25% load
  • Less than 3% THD
  • Electric start
  • Four GFCI outlets
  • CO sensor
  • Weight of 213.9 lb (97 kg)
  • 3 years limited residential and 270 days limited commercial warranties

Cons

  • Not a lot of customers yet

One thing to keep in mind is the low number of customer reviews. This adds some uncertainty about how good the Champion 201175 8500 model really is.

That being said, after reviewing many generators, I can say that there are not many cases where Champion generators really disappoint customers.

It is also helpful to know that propane tends to store a lot longer than gasoline.

In turn, the dual fuel feature of the Champion 201175 8500 makes it an extra good quiet generator for situations like power outages and off-grid living.

So if you don’t mind the lower number of customer reviews, this 240 volt generator is likely worth considering.

5. GENMAX GM5500i

This GENMAX GM5500i is a relatively quiet 240v generator with 62 dBA. However, unless you are on a tight budget, you likely don’t want to go for this model.

GENMAX GM5500i

The main reason for this is that the GENMAX GM5500i and similar models tend to have a somewhat high rate of technical issues.

Even if you are not in the middle of a power outage, not having power on your RV camping trip or van life journey when you need it can be annoying too.

On top of that, there are cases when customers find it challenging to get help from support. This applies to situations where the person is still within the short one year warranty.

Pros

  • Relatively low noise levels of 62 dBA
  • GENMAX GM5500i offers 5500 starting watts, 5000 running watts, 30 amps, and 240 volts
  • Nice run time of 13 hours at 25% load
  • Less than 3% THD
  • Has electric start
  • Four GFCI outlets
  • CO sensor
  • Weight of 127.8 lb (58 kg)
  • 1 year limited warranty
  • Relatively budget-friendly

Cons

  • Relatively short warranty
  • Decent number of technical issues

Everything above still applies but the GENMAX GM5500i has a few positive points too.

For example, the weight of 127.8 lb (58 kg) is relatively light compared to the other silent 240v generators on this list.

This good portability can be helpful if you are on a busy camping trip with many stops that involves often taking the inverter generator in and out of your vehicle.

Additionally, because it is a relatively small 240v generator, it is relatively easy to fit the GENMAX GM5500i in your car or RV.

Lastly, the GENMAX GM5500i is relatively budget-friendly.

People who are on a tight budget but still want one of the quietest 240 volt generators could still consider this model.

What should you consider in a quiet 240v generator?

You should mainly consider details like the decibel ratings, customer reviews mentioning noise levels, and 240 volt outlets in a quiet 240v generator.

  • Power capacity
  • Outlets
  • Portability
  • Run time
  • THD levels
  • Fuel consumption
  • User reviews
