REVIEWS AND TOP PICKS FOR THE BEST PORTABLE DIESEL GENERATORS IN 2022

DIESEL GENERATORS

Diesel generators are used for a variety of different purposes. The main reason is that diesel engines are designed to be workhorses. They require less maintenance than their gas-powered version. Another advantage is that diesel generators are more fuel efficient.

Anyone who is near a running diesel engine is familiar with its distinctive sound and odour. The clicking noise might almost drive you insane, and the odour can give you a headache.

We’ve made it simple for you to weigh the advantages and disadvantages of different models and make an informed decision about not just the best generator but also your investment.

A Comparison of Some Diesel Engines

Generac 6864 Portable Diesel Generator – Best Overall

The Generac 6864 Diesel Powered Portable Generator stands out from the competition because to its durability and power, which is why we named it our top overall option. It has a 5,500-watt starting power and a 12-gallon fuel tank, allowing it to run for over 30 hours. The Generac packs a lot of features into this 254-pound portable generator, and you might be wondering how you’re going to transport such a big machine.

The Yanmar True Power Technology 435cc industrial-grade engine has fuel-efficient idle management and air-cooled direct injection. True Power Technology reduces overall harmonic distortion to less than 6%, allowing sensitive electronics, equipment, and appliances to run more smoothly. To start the Generac, you can use the pull start, which has been known to be problematic, so you’ll need to buy the batteries. The battery has a 330 CCA rating and will power the single-touch electronic start system. It’s also the only way for the fuel cutoff to function.

Your generator is protected by a 114-inch steel frame that is fully welded and built to last. The frame has a completely integrated lifting eye that makes it simple to carry or secure the generator.

Pros

  • Fuel tank with a capacity of 12 gallons
  • Electric start with a single touch
  • Long-duration run
  • Idling that saves you money on gas

Cons Of Industrial Quality

  • Start with a difficult pull
  • When operating, it is quite loud.
  • Has a weight of 254 pounds.
  • Separately purchased wheels and battery 2.
  • Cummins Onan Quiet Series Diesel RV Generator Cummins Onan Quiet Series Diesel RV Generator

The Onan Quiet Series Diesel RV Generators

They are the most powerful diesel generators available. They are quiet and vibration-free, and they meet all of the National Park Service’s requirements. They’re so quiet, in fact, that they’re virtually as silent as their gasoline-powered counterparts and less quiet than solar generators though. This Onan 10HDKCA-11506 is a little more expensive, but it delivers 10,000 watts of electricity, which is enough to operate three rooftop air conditioners.

The enclosed cooling, muffler, and intake systems, as well as a heavy-duty air cleaner, are included in this feature-rich machine. It operates at a consistent pace and produces pure sine wave electrical output, ensuring that your appliances are safe. It can generate 120 and 240 volts for a number of uses. The generator has a USDA spark arrestor and a maintenance-free electronic governor for further safety.

It has a huge fuel tank capacity and uses an average amount of fuel during operation. An hour metre is included for convenience, and it also has self-diagnosing capabilities. The disadvantage is that this generator is quite hefty, weighing in at 785 pounds. It’s not something you’d consider transportable.

PROS

  • Powerful ten thousand watts
  • Operation that is quiet
  • Auto-shutdown

CONS OF THE HOUR METER

  • It is really heavy.
  • Extremely costly

8.0HDKAK-1046 Onan Quiet Diesel Generator

Some of the features of the 8,000-watt Onan generator are similar to those of its more powerful brother, which we previously evaluated. It’s also on the pricey side and a heavyweight at 420 pounds. As a result, transporting it may be challenging, and there are no additional accessories available to assist.

The Onan 8.0HDKAK-1046 Quiet Diesel Generator, on the other hand, is our Premium pick. It has a 3-cylinder diesel engine with computer-controlled variable speed operation and an intake silencer in a sound-controlled housing. This makes the unit exceptionally quiet to run, much below the sound level restrictions of the National Park Service.

It is equipped with a digital voltage regulation mechanism that produces high-quality sine wave electrical output. The heavy-duty air cleaner, internal radiator, maintenance-free electronic governor, and bottom air inlet and exit are just a few of the features that distinguish this generator. It’s a full package when you consider the Onan 8000 includes a USDA spark arrestor and fulfils EPA and California emissions requirements.

As previously stated, this is heavier and may appear difficult to move, especially if you plan to use it in your RV, but it will power two 15,000 BTU air conditioners and a variety of other appliances, so you may still want to consider taking it with you on the road.

PROS

  • Computer-controlled variable speed that is extremely silent
  • Maintenance is simple.
  • USDA Spark arrestor with a power output of 1,000 watts CONS
  • Inexpensive
  • Quite hefty
  • Transport is difficult.
