5 Best 240 volt generators reviewed in-depth

If you already have a specific subcategory in mind, the list of top picks and performance table could be enough to make a decision.

That being said, you may also find it easier to choose between the best 240v generators after checking out the in-depth reviews below.

1. Champion 201066 – Best 240 volt inverter generator

Our top pick for the best 240 volt inverter generator is the Champion 201066 6500 thanks to its combination of good features, great reliability, and reasonable price.

You do want to know about the 6500 starting watts and 5250 running watts of the Champion 201066 6500.

This is a good amount of power but at 240 volts, you will “only” be able to get 21.8 running amps.

Additionally, the specific 6500 peak watt version of this portable Champion generator does not have that many reviews yet.

Pros

  • Champion 201066 offers 6500 starting watts, 5250 running watts, 30 amps, and 240 volts
  • Noise levels of 69 dBA
  • Nice run time of 13.5 hours at 25% load
  • Less than 3% THD
  • Weight of 123 lb (55.9 kg)
  • Four GFCI outlets
  • Has a CO sensor
  • 3 years limited residential and 1 year limited commercial warranties

Cons

  • You may want more power
  • More customer reviews for this specific model would be welcome

That being said, similar Champion generators like the 50 amp model on this list tend to perform really well.

In turn, the Champion 201066 6500 should be more than reliable enough too.

Together with the run time of 13.5 hours at 25% load, you may even be to run certain AC systems for a good part of the night.

Whether the somewhat louder noise levels of 69 dBA are low enough for this purpose and your neighbors is another question.

So while the Champion 201066 6500 is not perfect in power capacity, noise levels, and run time, it is still a great 240 volt generator overall.

2. Westinghouse wGen6000 – Best 240 volt non-inverter generator

The choice for the best 240v non-inverter was challenging but ultimately the Westinghouse wGen6000 got the top spot thanks to its reliability reputation.

If this is not as important for you, for example when running certain power tools, the Predator 9000 could be a good choice in this category too.

Westinghouse wGen6000

With both of these portable 240 volt generators, you want to keep the non-inverter high THD power in mind.

In simpler words, you don’t want to power sensitive electronics like a TV, certain air conditioning systems, and certain refrigerators with these generators.

If you don’t mind this because you want to run something like a well pump, the long run time of 13 hours at 50% load positively stands out in the Westinghouse wGen6000.

Pros

  • Westinghouse WGen6000 offers 7500 starting watts, 6000 running watts, 30 amps, and 240 volts
  • Great run time of 13 hours at 50% load
  • Electric start
  • Four GFCI outlets
  • Weight of 183 lb (83 kg)
  • Relatively positive customer reviews
  • 3 years limited residential and 1 year limited commercial warranties
  • A lot of customers
  • Budget-friendly

Cons

  • THD of less than 23% is not suited for sensitive electronics
  • There are a few cases of issues with the electric start battery
  • Noise levels of 72 dBA are somewhat loud as some customers mention

This run time makes it so you can enjoy your 6000 running watts and 25 running amps for a long time before having to refuel.

Additionally, the electric start makes it more convenient to get the Westinghouse wGen6000 going.

At least if the electric start functions as desired. There are a few cases where customers had issues with this area of the portable generator.

The Westinghouse wGen6000 noise levels of 72 dBA are not ideal either.

That being said, with how solid the Westinghouse wGen6000 is in other areas and how budget-friendly it is, this is still a good 240 volt generator overall.

3. DuroMax XP9000iH – Best 240 volt dual fuel inverter generator

The DuroMax XP9000iH is not just a large 240 volt inverter generator. It also has a dual fuel feature.

That means you can also run this portable 240v generator on propane which offers a few benefits.

DuroMax XP9000iH

First of all, propane typically stores longer than gasoline. This makes it more convenient to stay prepared for power outages and to live off-grid.

Secondly, if you only want to use your 240 volt inverter generator occasionally, propane generally requires less maintenance.

On the flip side, you do want to know there are a decent number of cases where customers had issues with the DuroMax XP9000iH.

Pros

  • DuroMax XP9000iH offers 9000 starting watts, 7600 running watts, 30 amps, and 240 volts (gasoline)
  • Parallel capability
  • Dual fuel so can run on propane (LPG) too
  • Noise levels of 68 dB
  • Good run time of 20 hours at 25% load
  • Good gasoline fuel efficiency
  • Less than 5% THD
  • Electric and remote start
  • Four GFCI outlets
  • CO sensor
  • Weight of 237 lb (107.5 kg)
  • 3 years limited residential and 1 year limited commercial warranties
  • A lot of customers

Cons

  • Does not have a 50 amp outlet
  • Some cases of early technical issues
  • A few cases where the generator does not offer the running watts mentioned

At the same time, there are not that many good alternatives in the 240v dual fuel inverter generator category.

You could consider the Champion 100719 if you don’t mind the lower number of customer reviews and/or like the Champion brand.

Additionally, if you don’t need the clean inverter power, you could also conclude the regular non-inverter Champion 100231.

That being said, the DuroMax XP9000iH is still the top pick for a reason.

You will probably like the combination of power, run time, and convenient operation anyway.

4. Honda EU7000iS – Quietest 240 volt generator

The Honda EU7000iS is not just the quietest 240 volt generator but also just a solid machine overall.

However, unless you really value the 52 to 58 dBA at 25% to 100% load, this generator will likely be a bit too expensive.

Especially if you consider that there are still a few exceptional cases of technical issues.

At the same time, the Honda EU7000iS also still positively stands out in details like its BlueTooth capability.

Pros

  • Honda EU7000iS offers 7000 starting watts, 5500 running watts, 30 amps, and 240 volts
  • Parallel capability
  • Quietest 240 volt generator with noise levels of 52 to 58 dBA (25% to 100% load)
  • 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
  • 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
  • You may need help moving the weight of 263.2 lb (119.4 kg)

Through the Honda My Generator app, you can start, stop, and track the performance of the Honda EU7000iS from a distance.

And even if you don’t have your phone with you, the electric start makes this 240v generator relatively easy to start anyway.

You do want to keep the heavy weight of 263.2 lb (119.4 kg) in mind. This can be challenging to move.

Especially on uneven terrain while camping or at an outdoor event.

In short, the Honda EU7000iS is pricey but its quiet noise levels and convenient operation could be worth the investment for certain people and situations.

5. Champion 201067 – Best 50 amp 240v generator

If you are interested in a strong 240 volt generator with a 50 amp outlet, the Champion 201067 9000 will likely be the right choice for you.

You will not be able to get the full 50 amps and 240 volts at the same time but having both options in a single portable generator is valuable too.

These details allow you to get a lot of electricity through one outlet and to power certain stronger devices.

In turn, the Champion 201067 9000 can be especially useful for purposes like home backup power.

Pros

  • Champion 201067 offers 9000 starting watts, 7250 running watts, 50 amps, and 240 volts
  • Run time of 10.5 hours at 25% load
  • Less than 3% THD
  • Electric start
  • CO sensor
  • Four GFCI outlets
  • Weight of 152.2 lb (69 kg)
  • Very positive customer reviews
  • 3 years limited residential and 270 days limited commercial warranties
  • A lot of customers

Cons

  • Run time is not the most impressive
  • Noise levels of 72 dBA are somewhat loud

All this power the Champion 201067 9000 offers is also clean low THD inverter power. That means sensitive electronics should not be an issue.

One thing to keep in mind is that the noise levels of 72 dBA are on the louder side.

Additionally, the somewhat shorter run time of 10.5 hours at 25% load is not the most impressive either.

On the flip side, with this many watts, 10.5 hours should still be enough to run reasonably sized AC systems and refrigerators overnight.

How budget-friendly the Champion 201067 9000 offers all of this functionality stands out positively too.
