Best 5 Large Inverter Generators for Heavy Used.

Pulsar PG4000iSR – My top pick

The Pulsar PG4000iSR might not be the best workhorse in our test group but it highlights the parallel capability to double the output if needed.

That said, when hooked up to a travel trailer, it’s still able to run a 15,000 BTU air conditioner with no problems.

The method is very soft and smooth.

At 10 feet away, it emits just 62 decibels of sound – equal to our normal conversations so you can feel ease in mind to use it anywhere. No matter it’s at your home or on the campground.

The best thing is you don’t have to go out and in the house to open it as now, there is a wireless remote start included. It can work from a distance of 80 feet away, which is so impressive.

Carrying this powerful generator around isn’t a thing as well since it is designed with two hard wheels and one telescoping handle.

Product Specs

Peak Watts/Running Watts 4000W/3500W
Noise Level 63 dB
Max Runtime 15 hours (1/2 load)
Highlight Features wireless remote start; Handle and Never-Flat wheels; Parallel capability; 120V 30Amp RV outlet;

Across the board in our tests, the Pulsar PG4000iSR thoroughly impressed us with its perfect balance of power output, quiet operation, and maneuverability.

Westinghouse iGen4500DF – Ultra quiet

While other brands have to tradeoff between power and noise for their generators, with this Westinghouse, you’ll get the best of both worlds.

But for what we really feel thankful is its dual-fuel technology.

You don’t have to unplug your electronics and shut down the machine just to switch from gas to propane. It can keep working while you do that and the sine wave is still stable to not damage the vulnerable devices.

Not to say that the remote electric start, in this case, is much better. It’s responsible for 327 feet away.

And while being so functional, the iGen4500DF is added to an LED data center to let you easily track different indicators in one spot.

Product Specs

Peak Watts/Running Watts 4500W/3700W
Noise Level 52 dB
Max Runtime 18 hours (1/4 load)
Highlight Features dual-fuel technology; Remote Start With Included Key Fob, Electric and Recoil Start; Led Data Center

If you’re looking for an ultra-quiet yet powerful generator to keep a good friendship with your neighbors, the Westinghouse iGen4500DF is our recommendation.

Honda Eu7000is – Premium quality

The Honda Eu7000is is more expensive than other counterparts in this list but that price has included a starting battery, a wheel kit, a 3-year warranty, and more.

It’s the only generator in our list giving 7000 watts of peak power whereas running at the lowest volume.

We guess, the secret comes from its advanced inverter technology and Honda GX390 EFI Engine, which is known for the ability to reduce maintenance linked with carbs and fuel storage. And the Eco Throttle™ System keeps the whole operation whisper silent with fuel efficiency.

Furthermore, it’s attached to Honda Oil Alert to auto-shutdown the engine whenever oil exceeds the safe operating levels.

If you prefer some technical information, the Eu7000is meets all ETL & NEC Standards.

Product Specs

Peak Watts/Running Watts 7000W/5500W
Noise Level 50 – 62 dB
Max Runtime 18 hours (1/2 load)
Highlight Features Honda Oil Alert; Electric Start; Eco Throttle™ System; Output Indicator & Overload Alarm; GFCI outlets

For guys who are serious about choosing a premium-quality powerful generator for full-time RV life, the Honda Eu7000is won’t let you down.

Westinghouse iPro4200 – Most sought-after hybrid generator

What makes Westinghouse iPro4200 as the most sought-after hybrid generator is its perfect combination of both conventional open-frame generators and the inverter.

In short, it’s housed in a rugged conventional frame while creating as clean power as an inverter generator with super-low operating volume.

Product Specs

Peak Watts/Running Watts 4200W/3500W
Noise Level 62 dB
Max Runtime 18 hours
Highlight Features OHSA Compliant; Fuel-Saving “Efficiency Mode,” and Automatic Low Oil Shutoff

Designed to run job site essentials and power tools, the ground-breaking Westinghouse iPro4200 is the best bet for industrial applications and professionals.

Champion 6250-Watt – Highest Wattage

Saving the best for last, here is the Champion 6250-watt generator, known for its 20% lighter weight and 50% quieter volume than the traditional Champion 5000-watt.

The unit is boasted having a more efficient mechanical design, quieter technology digital Inverter components in addition to some cost-effective power solutions.

The biggest selling point is its intelligence where you can easily track many different indicators, such as operating hours, frequency, and voltage.

It’s also the only option in our test groups to provide the Cold Start and Quick Drain Oil Tube for easier oil changes. If you’re tired of spillage whenever fueling your generator, this is, for sure, not a thing.

Product Specs

Peak Watts/Running Watts 6250W/5000W
Noise Level 69 dB
