Find out what the best 50 amp inverter generators are so you can avoid adapters and get more clean power from one outlet.

  1. Best 50 amp inverter generator: Champion 201067 9000 (7250 running watts)
  2. Best dual fuel 50 amp inverter generator: Pulsar PGD95BISCO (7200 running watts)
  3. Quietest 50 amp inverter generator: Powerhorse 7500i (6500 running watts)
  4. Largest 50 amp inverter generator: AIVOLT 10000 (8000 running watts)
  5. GENMAX GM9000iE (7600 running watts)

Keep in mind that even the most powerful inverter generators on this list can not power 50 running amps at 240 volts (but 120 volts is typically no problem).

Besides that, options lower on the list could be better for your personal preferences and needs.

Best 50 amp inverter generators performance on a score of 10 in important categories*

*Compared to similar generators and sometimes based on customer input

1. Champion 201067 9000

The Champion 201067 9000 is the best 50 amp inverter generator thanks to its 50 amp outlet, reliability, and reasonable price.

It will likely be no surprise that the Champion 201067 9000 is not just the best large inverter generator but also the best 50 amp model.

With 9000 starting watts, 7250 running watts, 240 volts, and a 50 amp outlet you will likely have enough clean power to run the devices you have.

These power capacities may not stand out that much in themselves but the Champion 201067 9000 is also relatively budget-friendly.

One downside you do want to keep in mind is that this is one of the louder 50 amp inverter generators on this list.

Pros

  • Champion 201067 9000 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)
  • Relatively positive customer reviews
  • 3 years limited residential and 270 days limited commercial warranties
  • A lot of customers
  • Budget-friendly for a 50 amp inverter generator

Cons

  • Run time is not the most impressive
  • Noise levels of 72 dBA are somewhat louder than the other options on the list

In turn, you could still consider quieter models for home backup power in small neighborhoods or busy RV camping spots.

The run time of 10.5 hours at 25% load of the Champion 201067 9000 is also not that impressive compared to other options but is still relatively good on itself.

You may also like the relatively low weight of 152.2 pounds which is at least somewhat easier to move around than many other 50 amp generators.

In short, if you don’t mind the somewhat higher decibel levels and somewhat shorter run time, the Champion 201067 9000 is likely the right choice for you.

2. Pulsar PGD95BISCO

The Pulsar PGD95BISCO is the best dual fuel 50 amp inverter generator which means it can run on both gasoline and propane.

Pulsar PGD95BISCO

This dual fuel feature can be helpful for home backup power, off-grid living, or any other situation where you want to be able to use propane which stores longer.

You do want to know that the market for dual fuel 50 amp inverter generators is not that big.

The Pulsar PGD95BISCO currently looks like the best model available but it does not have that many customers yet.

Pros

  • Pulsar PGD95BISCO offers 9500 starting watts, 7200 running watts, 50 amps, and 240 volts (gasoline)
  • Parallel capability
  • Dual fuel feature so you can run on propane (LPG) too
  • Relatively low noise levels of 62 dBA
  • Nice run time of 9.5 hours at 50% load
  • Clean inverter THD
  • Has remote and electric start
  • Four GFCI outlets
  • 3 years limited warranty

Cons

  • You likely need some help moving the weight of 281 lb (127.5 kg)
  • Not a lot of customers yet

Additionally, the Pulsar brand has both good and bad generators. So while the PGD95BISCO looks good on paper, more reviews would be welcome.

That being said, partly to the lack of good alternatives, the nice run time, remote start, and parallel capability of the Pulsar PGD95BISCO may convince you anyway.

You also get a relatively quiet 50 amp inverter generator with noise levels of 62 dBA. This can be helpful for more crowded camping or neighborhoods (and your ears or night of rest).

So if you want the option to run your 50 amp inverter generator on propane too, you could still consider the somewhat less proven Pulsar PGD95BISCO.

3. Powerhorse 7500i

The Powerhorse 7500i is the quietest 50 amp inverter generator with an impressive 55 dBA at 25% load.

Before looking into the rest of the pros and cons of the Powerhorse 7500i, you want to know that this is a relatively weak 50 amp inverter generator with “only” 6500 running watts.

However, if this is enough for you, the Powerhorse 7500i can be interesting in the sense that it is the quietest 50 amp generator on the market.

The impressive 55 dBA at 25% load means that the Powerhorse 7500i can be especially great for tailgating, busy RV campings, small neighborhoods, or other situations where quiet operation is welcome.

Additionally, you get really clean power with only 1.2% THD which should be more than enough to avoid damage to sensitive electronics.

Pros

  • Powerhorse 7500i offers 7500 starting watts, 6500 running watts, 50 amps, and 240 volts
  • Quietest 50 amp inverter generator with 55 dBA at 25% load and 63.9 dBA at rated load
  • Good run time of 16 hours at 25% load
  • THD of 1.5%
  • Has electric start
  • Four GFCI outlets
  • Very positive customer reviews
  • 2 years limited residential and 90 days limited commercial warranties

Cons

  • Some people will find 6500 running watts lacking
  • Relatively short commercial warranty
  • Pricey for its power level
  • Fuel efficiency is not that good
  • You likely need some help moving the weight of 287 lb (130.2 kg)

The long run time of 16 hours at 25% load also makes the Powerhorse 7500i a good 50 amp inverter generator for something like running an (RV) air conditioner overnight.

Some things you do want to keep in mind are the short commercial warranty, price tag, and suboptimal fuel efficiency.

And unless you don’t mind a few extra workouts, the heavy weight of the Powerhorse 7500i is not ideal for busy road trips with many stops.

All in all, the Powerhorse 7500i does not offer the most power for the price tag but could be worth it for people who want a very quiet 50 amp inverter generator.

4. AIVOLT 10000

The AIVOLT 10000 is the largest inverter generator on our list and has the matching 50 amp outlet to get all that power to your devices.

AIVOLT 10000

Additionally, this is another duel fuel generator which means you get the benefits of fuel flexibility and running on propane.

On the other hand, you do need to know that AIVOLT is not the most proven generator brand out there.

So far, the AIVOLT customer reviews, including the one for the 10000 peak watt model, look good but more user feedback would be welcome.

Pros

  • AIVOLT 10000 offers 10000 starting watts, 8000 running watts, 50 amps, and 240 volts (gasoline)
  • Parallel capability
  • Dual fuel feature so you can run on propane (LPG) too
  • Relatively low noise levels of 61 dBA
  • Good run time of 19 hours at 25% load
  • Less than 3% THD
  • Has remote and electric start
  • Four GFCI outlets
  • 2 years limited warranty

Cons

  • Not the most proven generator brand
  • You likely need some help moving the weight of 299 lb (135.6 kg)

The few individuals that actually need a 50 amp inverter generator with this much power can still consider the AIVOLT 10000.

Its impressive run time of 19 hours at 25% load should be good enough for running an AC overnight, a day of serious DIY work at home, and potentially even powering a food truck or event.

The low 61 dBA noise levels of the AIVOLT 10000 will also make it so you can do these things in a reasonably quiet way.

You may like the convenience of the remote and electric start too.

5. GENMAX GM9000iE

The GENMAX GM9000iE is mostly on the list because the market of 50 amp inverter generators is not that big and I do want to show you enough options.

I mention this because the GENMAX GM9000iE is not as high-quality as you may expect from a list of the best generator choices.

GENMAX GM9000IE

There are a decent number of cases where customers got a GENMAX GM9000iE that did not work as desired or started having issues relatively soon.

Additionally, GENMAX customer support does not really have a reputation for being fast or helpful. Even when you are still within the short one-year warranty.

Pros

  • GENMAX GM9000iE offers 9000 starting watts, 7600 running watts, 50 amps, and 240 volts
  • Parallel capability
  • Relatively low noise levels of 62 dBA
  • Run time of 14 hours at 25% load
  • Less than 5% THD
  • Weight of 233.7 lb (106 kg)
  • Electric and remote start
  • Four GFCI outlets
  • CO sensor
  • Also dual fuel version available
  • 1 year limited warranty

Cons

  • Relatively short warranty
  • Decent number of cases where customers got a model that did not work as desired or early wear and tear
  • Fuel efficiency is not that good

At the same time, it is still worth noting that GENMAX did create a strong 50 amp inverter generator with nice specifications.

Especially the low noise levels of 62 dBA and solid run time of 14 hours at 25% load positively stand out.

These details can be good enough for running the GENMAX GM9000iE on a busy RV camping or as home backup power for your air conditioning in case of a power outage.

That being said, even if you want to use your machine for these purposes, you will likely prefer one of the other best 50 amp inverter generators on this list.
