Discover the quietest 5500 watt generators so you can satisfy your power needs while keeping the noise levels down.

Quietest 5500 watt generators overview

I often try to include only 5500 peak watt generators for quietest selection lists like this.

However, due to the small number of actually quiet models, I also included generators from slightly higher peak watt categories.

  1. Yamaha EF6300iSDE – Quietest 5500+ watt generator (6300 peak watts, 58 dBA)
  2. Champion 201001 – Best quiet 5500 watt generator (5500 peak watts, 61 dBA)
  3. GENMAX 5500i (5500 peak watts, 62 dBA)
  4. GENMAX GM6000iED (6000 peak watts, 63 dBA)
  5. Honda EM6500SX (6500 peak watts, 64 dBA at 50% load)

As you can expect, 5500+ watt generators lower on the list could still be the better choice in your personal situation.

Other details I looked at

To put this list together I mainly used the decibel ratings and customer reviews mentioning noise of 5500 to 6500 peak watts generators.

That being said, since you likely care about overall performance and value too, I also looked at other details for the reviews of the quietest 5500 watt generators in the next section.

Some of these other details I considered are:

  • Run time, fuel types, outlets, portability, etc.
  • User reviews
  • Anecdotal reviews from experts

5 Quietest 5500 watt generators reviewed in detail

As mentioned, noise levels are likely not the only thing you care about.

The detailed reviews below can help you find the quiet 5500 watt generator that is actually the best for your situation.

1. Yamaha EF6300iSDE – Quietest 5500+ watt generator

Because there are not enough silent peak watt models, this Yamaha EF6300iSDE with 5500 running watts is the quietest generator on the list.

However, the first thing to note is that this will not be the best choice for many people due to a few reasons.

Yamaha EF6300iSDE

The main one is that the Yamaha EF6300iSDE is extremely expensive compared to many other quiet 5500 watt generators.

Up to the point where you can invest in two smaller generators with parallel capability to get the same amount of power and noise levels with less money.

Pros

  • Quietest 5500+ watt generator with 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 compared to other quiet 5500 watt generators
  • A few exceptional cases of technical difficulties
  • Maintenance can be challenging
  • Moving the generator around can be challenging

Additionally, you would hope for fewer cases of technical issues and notes about maintenance and generator navigation being challenging at this price point.

It is still worth noting that the Yamaha EF6300iSDE still has other benefits besides its super quiet noise levels.

The electric start and optional remote start make operating this 5500 running watt generator relatively convenient.

On top of that, the CO sensor reduces the risk of dangerous carbon monoxide buildup around the machine.

That being said, again, the Yamaha EF6300iSDE may be a solid and definitely a quiet 5500+ watt generator but the price will often be too much.

2. Champion 201001 – Best quiet 5500 watt generator

The Champion 201001 may be a few decibels louder than the previous option but is likely still the best quiet 5500 watt generator for you.

Unless you want to be able to run on propane too. Then could the Champion 201003, which is the dual fuel version without remote start, be the best option.

Both of these variations have a decibel rating of 61 dBA (typically at 25% load and 23 feet) which is definitely quiet considering a regular conversation is around 60 decibels.

In combination with the long run time of 20 hours at 25% load, the Champion 201001 can be a great option for running something like an RV AC or refrigerator overnight.

Pros

  • Relatively low noise levels of 61 dBA
  • Champion 201001 offers 5500 starting watts, 4000 running watts, 30 amps, and 120 volts
  • Parallel capability
  • Dual fuel version without remote start available too
  • Good run time of 20 hours at 25% load
  • Good fuel efficiency
  • Less than 3% THD
  • Weight of 119 lb (54 kg)
  • Has electric and remote start
  • Top rated 5500 watt generator
  • 3 years limited residential and 270 days limited commercial warranties
  • A lot of customers

Cons

  • Moving the generator over bumpy terrain can be challenging

If you go for the gasoline-only model, the remote start makes it extra convenient to start and stop using the clean inverter power of the Champion 201001.

You don’t even have to get out of your camping chair or leave your favorite spot on the boat deck.

Another big positive of the Champion 201001 is the great reliability the positive customer reviews imply.

The one tiny downside of this quietest 5500 peak watt generator is that its small wheels can make it hard to move over bumpy terrain.

That being said, the Champion 201001 or the dual fuel version will likely be the generator for you.

3. GENMAX 5500i

The GENMAX 5500i gets a spot on this list of the quietest 5500 watt generators thanks to the relatively low noise levels of 62 dBA.

On the other hand, you do need to know that this is definitely not the highest-quality inverter generator on the list.

GENMAX 5500i

How often customers have technical issues with the GENMAX 5500i is definitely above average.

It also looks like these customers often find it hard to actually get help from GENMAX support. Even when they are still within the one year warranty period.

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

Cons

  • Relatively short warranty
  • Decent number of technical issues
  • Moving the generator over uneven terrain can be challenging

The suboptimal reliability is a big downside since you don’t want the risk of discovering your refrigerator full of food or something similar will not be able to get the power it needs.

This is unfortunate because the GENMAX GM5500i looks good on paper with its electric start, GFCI outlets, and CO sensor.

These details make the quiet 5500 watt generator more convenient and safer to use.

In short, while the GENMAX GM5500i may look good at first, its high rate of technical issues is likely too much.

Especially because the Champion 201001 is such a good alternative.

4. GENMAX GM6000iED

The GENMAX GM6000iED is very similar to the GENMAX 5500i in terms of silent operation but also in terms of technical issues.

You even risk a little more since the GENMAX GM6000iED is pricier with its higher power capacity and dual fuel feature.

GENMAX GM6000iED

Being able to run on propane can be useful because it stores longer than gasoline and requires less maintenance work.

The GENMAX GM6000iED is also still a relatively quiet 5500+ watt generator with a rating of 63 dBA.

Pros

  • Relatively low noise levels of 63 dBA
  • GENMAX GM6000IED offers 6000 starting watts, 5250 running watts, 30 amps, and 240 volts (gasoline)
  • Dual fuel feature allows you to run on propane too
  • Nice run time of 13 hours at 25% load
  • Less than 3% THD
  • Has electric and remote start
  • Has CO sensor
  • Weight of 117.9 lb (53.5 kg)
  • 1 year limited warranty

Cons

  • Decent number of technical issues
  • Pricey compared to many quiet 5500 watt generators
  • Moving the generator over uneven terrain can be challenging

However, the same principle from above still applies.

The lacking reliability of the GENMAX GM6000iED and the examples of trouble communicating with support are often too much.

You likely just want to go for the Champion 201003 instead even if you consider this alternative has less power and no CO sensor.

5. Honda EM6500SX

While its open frame design and non-inverter technology may give you a different idea, the Honda EM6500SX is actually relatively quiet with 64 dBA to 66 dBA at 50% to 100% load.

It is worth noting that “non-inverter” means you don’t want to run sensitive electronics like a TV, loudspeakers, and even certain refrigerators on the Honda EM6500SX.

Honda EM6500SX

Another downside of this generator is that it is expensive compared to most of the quietest 5500 watt generators.

On the other hand, the Honda EM6500SX also has a few unique positives like for example the app connectivity that could theoretically make it worth it.

Pros

  • Relatively low noise level rating of 64 dBA to 66 dBA (at 50% to 100% load)
  • Honda EM6500SX offers 6500 starting watts, 5500 running watts, 30 amps, and 240 volts
  • Can go to 7000 watts for 10 seconds to start large equipment
  • Run time of 9.8 hours at 50% load
  • Honda My Generator app connectivity (including remote start)
  • Has electric start
  • Has CO sensor
  • Four GFCI outlets
  • Weight of 231.7 lb (105.1 kg)
  • 3 years limited residential and 12 months limited commercial warranties

Cons

  • High THD is not suited for sensitive electronics
  • Expensive compared to many other quiet 5500 watt generators
  • Fuel efficiency is not that good
  • A few very exceptional cases of issues

In the Honda My Generator app you can track a variety of performance metrics and even start and stop the Honda EM6500SX remotely.

This removes the inconvenience of having to walk up to your generator to check these things during your camping trip, work day, or power outage.

Additionally, the CO sensor and GFCI outlets add safety by removing the risk of too much carbon monoxide buildup and overloading the generator.

So the Honda EM6500SX does go the extra way in categories like quiet operation, ease of use, and safety precautions.

However, this will often not be enough to justify the price of this quiet 5500 running watt generator.
