2. WEN DF250i – Best small propane inverter generator

If you only need a small amount of power, the WEN DF250i could be a better propane inverter generator for you and your budget.

With 2250 peak watts and 1800 running watts on propane, this inverter generator should still be able to power a refrigerator, coffee machine, laptop, and phone charger together.

WEN DF250i

You can also get a lot of functionality out of the WEN DF250i by starting up devices in certain orders and/or turning them on and off when you (don’t) need them.

Within this category of small propane inverter generators, the WEN DF250i may not be the most proven but does look like the best value for the money right now.

Pros

  • WEN DF250i offers 2250 starting watts, 1800 running watts, 18.7 amps, and 120 volts (propane)

3. DuroMax XP9000iH – Best for home backup

Larger propane inverter generators like the DuroMax XP9000iH can be useful for home backup power in case of a power outage.

A big reason for this is that propane generally stores longer than gasoline. In turn, being prepared for power grid hiccups requires less attention and time.

DuroMax XP9000iH

One thing you do want to keep in mind for this purpose is that the DuroMax XP9000iH does not have a 50 amp outlet.

That means connecting the propane inverter generator to your house can be a bit more challenging.

Pros

  • DuroMax XP9000iH offers 8550 starting watts, 7200 running watts, 30 amps, and 240 volts (propane)
  • Parallel capability
  • Dual fuel means generator can run on gasoline too
  • Noise levels of 68 dB
  • Run time of 9 hours at 25% load on a 20-lb propane tank
  • 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

  • Expensive compared to smaller propane inverter generators
  • 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

Additionally, you are limited to “only” 7200 watts from one outlet (240v x 30 amps). Even when running on gasoline.

Bigger propane-compatible inverter generators also tend to have a somewhat higher amount of technical issues than smaller models.

The DuroMax XP9000iH is still one of the more reliable models available but you do want to keep this in mind.

Something else to note is that more power means using up more propane too. As you can see from the run time, a bigger LPG tank could be useful.

Overall, the DuroMax XP9000iH may not be perfect but the combination of features, price, and reliability still earns it the spot of best propane inverter generator for home backup power.

4. Champion 200977 4250 – Best for off-grid living

When choosing the best propane generator for off-grid living details like reliability and clean inverter power have a bit more priority.

To avoid needing to travel a long way to repair broken electronics or a malfunctioning generator, investing in the Champion 200977 4250 can be a good idea.

You do want to try out this propane inverter generator when you get it since there are a few cases where the first model customers got did not function as desired.

However, after that, the only main concern is getting the 79 lb (35.8 kg) in and out of position due to the lack of wheels.

Pros

  • Champion 200977 4250 offers 4250 starting watts, 3150 running watts, 30 amps, and 120 volts (propane)
  • Parallel capability
  • Reasonable noise levels of 64 dBA
  • Long run time of 21 hours at 25% load on a 20-lb propane tank
  • Less than 3% THD
  • Weight of 79 lb (35.8 kg)
  • Very positive customer reviews
  • 3 years limited residential and 270 days limited commercial warranties
  • A lot of customers
  • Budget-friendly

Cons

  • No wheels so moving the propane inverter generator can be challenging
  • A few very exceptional cases where the first model customers got had issues

Another benefit of the Champion 200977 4250 for off-grid living is its nice propane fuel efficiency.

This means you will have to travel to a source of propane slightly less often or at least make it so you need a somewhat smaller LPG tank.

The 64 dBA noise levels of the Champion 200977 are not the quietest but knowing a regular conversation is around 60 decibels, this is still reasonable.

In combination with the solid features and budget-friendly price, the Champion 200977 4250 can definitely still be the right propane inverter generator for off-grid living situations.

The Westinghouse iGen4500DF will often be the best propane inverter generator but if you want a bit more power and don’t mind the noise levels, the Champion 201003 5500 can be for you.

With 5500 peak watts and 3600 running watts, devices with higher starting watts like a table saw, air compressor, and hot water heater can become an option.

Some people may also like the 12 VDC outlet and the electric start of the Champion 201003 5500.

This electric start makes it more convenient to get the propane inverter generator going for elderly individuals or just people who don’t like using a recoil start.

Pros

  • Champion 201003 offers 5500 starting watts, 3600 running watts, 30 amps, and 120 volts
  • Reasonable noise levels of 61 dBA
  • Run time of 15 hours at 25% load on a 20-lb propane tank
  • Less than 3% THD
  • Has electric start
  • Weight of 118 lb (53.5 kg)
  • Relatively positive customer reviews
  • 3 years limited residential and 270 days limited commercial warranties

Cons

  • Navigating bumpy terrain can be inconvenient

  • A few exceptional cases of technical issues

Two things you do want to keep in mind are that the Champion 201003 has somewhat below-average propane fuel efficiency and can be challenging to roll over bumpy terrain.

Additionally, there are a few exceptional cases where support had to help customers out with their technical issues.

That being said, while it is worth noting this, customers are still relatively positive about the Champion 201003 5500 overall.

You could be one of the people with power needs and personal preferences that make this inverter propane generator the best choice.
