10 Best Inverter Generator Reviews – 2019 Buying Guide

Best Inverter Generator Reviews

Inverter generators are a relatively new product to the world of generators and have been made possible by recent technological advances. Thanks to the creation of advanced industrial magnets and innovative electronics, these generators are able to deliver a more reliable stream of electricity than conventional generators can usually produce.

They work by taking the unpredictable swings of AC current produced by convention gas-powered generators and convert it directly into DC power. This DC electricity is then changed back, or inverted, back to AC power. This results in a single-phase source of power at the generator’s stated voltage. Which is why many people refer to the electricity produced by these devices as “clean.”

Although these generators usually produce improved run times, better efficiency and are usually quieter than gasoline-powered generators, that doesn’t mean that they’re ideal for every situation. If they’re pushed behind their design specifications or are overworked, then they can produce less than stellar results.

The Difference Between Conventional & Inverter Generators

Since the term inverter has gradually made itself into the public vernacular and is often incorrectly applied to many different kinds of generators, it can sometimes be confusing for consumers to understand the difference between inverter generators and conventional generators. In order to clarify things a bit, we’ve decided to put together this guide which will spell out the pros and cons of inverter generators.

How They Actually Work

Before you can understand the difference between conventional and inverter generators, you first have to know what generators do, what inverters do and what inverter generators are designed to do. Conventional Generators use either gas or propane to power a motor which drives an alternator. This motor runs at 3,600 RPM to generate the 120-Volts required for American households. If the motor jumps up or down, then that changes the frequency of that current.

Inverters draw power from a battery or a solar panel and then invert that power into alternating current. Inverter Generators produce power in the same way as a traditional generator, but it then converts that power into DC current. Why does it do that? So it can invert the current back into AC current. Doing it this way results in fewer frequency fluctuations.

The Benefits of Inverter Generators

Now, let’s examine some of the things that inverter generators are designed to do. Although this technology is still relatively new, there are some things that inverter do really well. Let’s examine some of the top features that generators with inverter technology provide to most users.

Size & Weight:  Typically, inverters are generally smaller and lighter than conventional generators. Although it’s not uncommon for conventional generators to be several hundred pounds, most inverter-style generators are 60-pounds or lighter. This means that they are easier to transport than traditional generators and are closer to being portable generators than traditional generators are. This makes these generators suitable for RV usage, for use in garages and for use in homes or workshops.

Noise Level: Another thing that makes inverter-style generators better than conventional ones is the fact that they’re usually quieter. And there’s a variety of different reasons why this is true. Inverter generators take advantage of newly designed motors and noise-dampening mufflers to reduce the sound of the motor. They also don’t have to maintain a constant speed as gas-powered generators do. They can cycle up or down, as demand requires it, and still maintain a constant voltage frequency. When the load is lighter, then the motor can throttle back a little bit. While most generators have a decibel rating of over 70-decibels, inverters usually have a decibel rating of 46 to 60-decibels.

Clean Power: Another advantage that an inverter generator has is that it delivers “clean” power. What we mean by this is that it produces a pure sine wave that just isn’t possible with a conventional generator. They accomplish this feat by inverting the AC current to DC and then back again. Traditional generators can’t reproduce the same stable energy that your home receives from your local electrical utility, but inverters can actually reproduce it quite well.

Fuel Efficiency: Inverter-style generators are almost always more energy efficient than gasoline-powered models. That’s because gas-powered generators have to run at a constant speed to deliver a constant stream of AC power. On the other hand, inverter-powered ones don’t have to run at one speed to deliver electricity. Since they’re converting it into DC power and then back into AC, the device can throttle back according to the energy needs of the user. This results in less gasoline or propane being used to run the device.

Run Time: For the same reasons that inverters are able to deliver significantly reduced noise levels and better fuel efficiency, they are also capable of delivering significantly better run times. In some cases, the improvement can be as significant as 20 to 40%.

Parallel Operation: Unlike regular generators, inverter-powered ones can be attached to one another in parallel. This allows the user to string together multiple units to increase power output. The only downside is that the user usually has to use the exact same models and there’s a limit to how many different generators can be strung together.

Disadvantages of Inverter Generators

Although there’s a whole list of advantages associated with these generators, that doesn’t mean that they’re perfect or they’re ideal for every situation. There are some situations where the user may be better off using a gas-powered generator instead of one with an inverter. Below are some of the disadvantages associated with these generators.

Limited Runtime: One of the main problems with these type of generators is that they have limited runtimes. This is due to the fact that the vast majority of them, if not all of them, have small gas tanks. Although their fuel efficiency is improved over gas generators, the smaller gas tank is no small obstacle to overcome. A smaller gas tank always equals less runtime.

Limited Power Output: Although gasoline-powered models are manufactured with ratings from 500-watts up to 40,000+ watts, there aren’t large inverter generators available. These generators normally are manufactured with power outputs anywhere between 500 and 4,500-Watts. There just aren’t that many models that produce higher voltages, and the maximum voltage amount is somewhat limited with these generators.

Expense: When compared directly to gas-powered units, inverter models generally cost more. Although there may be some inverter models that are cheaper than some gasoline-powered models with the same power output, most of the time the inverter generator is the highest priced model.

Determining Your Needs


Now that you know the pros and cons of these devices, you’ll want to decide what size generator you need to buy. Regardless of whether you want to buy an inverter generator or a gasoline-powered one, you’ll need to determine the wattage generator you’re going to need.

After all, you’ll want to make sure that you have enough power to run the items that you want to run. Below are some common appliances and the amount of power they need to run.

  • RV Air Conditioning: 2,800 to 3,000-Watts
  • Mini-Fridge: 200 to 350-Watts
  • Crockpot: 250-Watts
  • Television: 150 to 300-Watts
  • Laptop: 250 to 300-Watts
  • 20-Inch Fan: 130-Watts

Although the above figures are estimates, they should give the average user a pretty good idea of how much energy they are going to need. Of course, when estimating your wattage needs, you are not only going to determine the cumulative total of all of the power you need, but you are also going to want to factor in at least 10% for a buffer.

For example, if you have a crockpot using 250-watts and a fan using 130-watts, you are going to want to add 10% to those 380-watts. Therefore, you are going to need a generator which can produce at least 418-watts.

Fuel Type

Another important consideration to think about is the fuel type used for the generator and what your needs are. There are inverter generators which run on gasoline, some on solar and some on propane.

There are even generators which are a hybrid and can either run on gasoline or propane. You’ll want to make sure you purchase one that fits the type of fuel you need it to run on.

In Conclusion

As it can be clearly seen, there are not only a lot of great inverter generators available but there are also a number of reasons to own one. Of course, each individual has to determine how much they can afford to spend and what features they are looking for, but overall, these type of generators have the features that most people are looking for in a generator.
