Generators are important to have on hand. They enable you to gain access to an electrical power source in remote locations. Unfortunately, they are loud. As the generator runs to produce power for whatever you need to supply power to, sound can be a real issue. If you’re tailgating, camping, or using lights for a small job site, the noise can be disturbing and distracting. That’s where inverter generators come in. Regular generators are designed to run at full tilt, while inverter generators electronically control the throttle to meet the user’s demands. They only generate the power needed, which makes for super-quiet operation. There are various styles of inverter generators that perform in specific settings. Take a look at the top models on the market in the guide below.

Benefits of Inverter Generators

  • Portable, efficient, and reliable. It’s the best solution for those who need mobile, backup power, whether for outdoor recreational activities or during a power outage. Inverter generators are also very efficient—unlike conventional generators, they can adjust the engine speed to your power needs.
  • Quiet. If you need enough juice to power your essential items but hate the sound of loud, running engines, then an inverter generator is the best solution. They typically run at noises lower than 60 dB, which is just as loud as a normal conversation.
  • Produce “clean” electricity. Whether it’s an open frame inverter generator or a more compact one, the electricity produced will be safe for sensitive electronic items like laptops, mobile phones, and other gadgets.

Types of Inverter Generators

Small, Medium, or Open Frame

Small inverter generators, which have an output of between 2000 to 3000 watts, are useful for light activities like camping or tailgating. Medium-sized inverter generators, which have an output of between 3000 to 4500 watts, will allow you to power up essential items and are great for use at home, at a job site, or for an RV. Large, open frame inverter generators that have an output of 4500 watts and above, on the other hand, can power an entire home or serve as backup power for a construction site.

Top Brands

Briggs & Stratton

Briggs & Stratton started in 1908 and is based in Wauwatosa, Wis., is a gasoline engine manufacturer. It has facilities in the U.S. and worldwide, and one of its top products is the P3000 Power Smart Series Inverter Generator.

Westinghouse 

In 1886, Westinghouse was founded to develop the electrical infrastructure of the U.S. It eventually diversified into developing other technologies, from engines to generators, to other electronic equipment. One of its most popular generator products is the WH2200iXLT Portable Inverter Generator.

Generac

This U.S. and Canada-based company was founded in 1959, and it is one of the most popular home backup generator brands on the market today. It offers different kinds of generator products, from gasoline to diesel, to inverter generators. A popular Generac inverter generator is the GP2200i 2200 Watt Portable Inverter Generator.

Inverter Generator Pricing

  • Under $500: Inverter generators at this price range can vary, but they’ll typically be small to medium in size and capable of producing a maximum of 3000 watts.
  • $500 and up: Medium to large, open frame inverter generators will fall into this price range. They will typically be less portable but will offer an output of 3000 watts and above.

Key Features

Convenience

Not only should an inverter generator be quiet and relatively easy to lug around, but it also shouldn’t take an expert to operate. This is why the control panel should be user-friendly and easy to understand, with all the controls and the input and output ports laid out logically.

Power Delivery

Of course, this will depend on your power needs, but suffice to say, power delivery is an inverter generator’s power output that most determine whether it’s worth purchasing. If you need something for tailgating or camping, then a small, 2,000- to 3000-watt inverter generator will do. If it’s to power up fairly big household appliances during a power outage, then you’ll need more than that.

Number of Outlets

This will vary from generator to generator, and its size and power output will largely determine the number of outlets it will have. Small inverter generators will have around two to three 120V AC outlets and a few USB ports for smaller gadgets. In contrast, inverter generators with an output of 3500 watts and above will typically have more outlets with additional 240V plugs.

Other Considerations

  • Parallel Device Operation. Most inverter generators available on the market are parallel capable, which means that they can be paired and used together with another inverter generator from the same supplier to double the overall power output. With this feature, two or more inverter generators can be paired to generate the same power as a larger one.
  • Warranty. Inverter generators are easier to maintain than conventional generators that use more oil and need their parts replaced regularly. However, inverter generators will break down over time. And since an inverter generator is too complicated for someone without the relevant mechanical skills to fix, the warranty on parts and services that a unit comes with is an important consideration that buyers should look into.
  • Eco-Throttle Mode. This will either be built-in or come as a feature that can be switched on and off from the unit’s control panel. When switched on, this feature will allow the unit to save fuel by adjusting the engine speed to provide just as much power as you need.

Tips

  • Make sure to follow the guidelines in your generator’s manual, especially regarding the regular maintenance schedule. This will ensure that your inverter generator will be running at peak efficiency. If you use your inverter generator often, the maintenance schedule will give you a good idea of what you need to do based on the amount of time your inverter generator has been running.
  • Keep your inverter generator covered when not in use. Not only will this keep your generator from attracting dirt and dust, but it will also protect the generator from moisture, which can get into the wiring and cause shorts. 
  • Never use your inverter generator indoors because they produce carbon monoxide, which is fatal when inhaled. 

FAQs:

Q. How do you test an inverter generator?

You can test it with a voltmeter. Switch the meter to AC Voltage, connect its ground to the generator’s frame, and put the probes into the outlets. You should get a reading after.

Q. What are the disadvantages of an inverter generator?

Inverter generators are generally more reliable and efficient than conventional ones, and the only real disadvantage is that they are more expensive.

Q. Should I get an inverter generator?

This will depend on your power needs. But if you need a fair amount of backup clean energy that is convenient and portable, then an inverter generator is the best option on the market.

Final Thoughts

Our top pick for the best inverter generator is the Briggs & Stratton P3000 Power Smart Series Inverter Generator. It is portable, strong, quiet, and very easy to use. It also has many ports, making it the perfect generator for tailgating and other outdoor activities. If you need a less expensive but feature-rich option, try the Westinghouse WH2200iXLT Portable Inverter Generator.
