Best Inverter Generators Buying Guide

You can’t just go buy the first generator on sale at the local big box store. For an inverter generator to truly meet your needs, there are a few things you need to know.

Power Capacity and Efficiency

Before purchasing an inverter generator, consider how you’ll use it so you can find one with the power capacity and efficiency to meet your needs. A generator for tailgating and camping will have to meet very different criteria than one you’d choose to power a home when a storm knocks out the power. 

Understanding Wattage Requirements

The amount of power that an inverter generator can produce is described in watts. The higher the wattage, the more power the generator can produce. It’s helpful to break down wattage requirements into three categories: light-, medium-, and heavy-duty. 

  • Light-duty generators produce 3,000 watts or less.  They’re relatively compact and light, and they’re great for tailgating, tent camping, or even running a power tool.
  • Medium-duty generators have a bit more oomph, producing up to 4,500 watts. These generators can often run entire project sites, and RV power systems, and even serve as a backup generator to keep lights on and the refrigerator running during a power outage. They’re often very easy to move around, though they are quite heavy to lift. 
  • A heavy-duty inverter generator has the most power to offer, producing an excess of 4,500 watts. These generators can run entire homes when the power is out, but they’re often heavy and tough to move around. 

Fuel Efficiency and Run Time

Balancing the amount of power an inverter generator can produce and its fuel efficiency can be a tall order. Most of these generators can hold two to 10 gallons of gasoline, while some might run on propane (there are even some that can run on both). Since inverter generators are typically more fuel efficient, they’ll use less fuel to produce the same amount of power as a standard generator.   

It depends on the model and the load, run times of 8 to 12 hours are typical for gasoline generators. This is typically what their onboard tanks are sized to provide. Propane generators might consume more fuel than gasoline to produce the same amount of wattage, but since their tanks are external, it depends on the size of the tank, 

Portability and Size

Unless you have a dedicated enclosure for your inverter generator, the portability and size are important considerations.

Weight and Handle Design

Compact, lightweight generators are relatively light. They generally weigh between 30 and 60 pounds and can be lifted onto the tailgate of a truck or hauled up a set of stairs. They can go just about anywhere.

Medium-duty and heavy-duty generators are a different story. These models have heavier components and more robust frames, so they usually have a set of wheels and at least one handle. This allows the user to roll their 200 to 300-pound masses around easily, but they’re quite heavy to lift, even with a partner. 

Compact Dimensions and Storage

The benefit of a light-duty inverter generator is that they’re small and easy to store. They’re often under 2 feet long and high, and measure under a foot across. They can fit on a shelf when they’re not in use which is perfect for smaller garages low on storage space.

Medium- and heavy-duty inverter generators are compact compared to traditional generators, but storage can be an issue. A smaller model might measure 24 inches all the way around, while a larger, high-output inverter generator can be an entire foot longer. These generators need a dedicated space for storage. 

Decibel Ratings and Quiet Operation

One of the things that consumers value most about inverter generators is that they’re quieter than traditional generators. While they’re far from silent, inverter generators use smaller engines and these engines don’t have to work as hard to maintain frequency. 

Some of the quietest inverter generators can run as quietly as 60 decibels. Even a very large inverter generator may only produce 70 to 80 decibels. While traditional generators have improved their noise levels in recent years, they’re not nearly as quiet. 

Additional Features and Technologies

Some additional features and technologies might make one inverter generator more suitable for your needs than another. 

Parallel Capabilities

Parallel capabilities refer to a generator’s ability to be wired in with another generator, increasing the generators’ output. Some models are parallel compatible, while others are not. Users will have to buy a brand-specific kit to link two generators, but this is a great way to supplement power needs with smaller generators. 

Smart Controls and Remote Operation

Another point to consider is that many inverter generators now come with smart controls and remote operation. These models can report their statuses back to the user while they’re running, allowing the user to track them with an app. Run time, temperature, output, and other readings are available.

Remote operation can be a big plus for folks. Being able to start a generator without heading outside in a storm or another scenario can help keep users safe and comfortable. This is also true for RV generators, which many campgrounds limit the hours during which they can run. 

Uses of an Inverter Generator

As mentioned earlier, how you plan to use your generator has a lot to do with choosing the right model. The following are some common uses for inverter generators.

Recreational and Outdoor Activities

Inverter generators are a great choice for recreational and outdoor activities. They can tag along for tailgating and outdoor events to provide power for entertainment, cooking, and charging devices while waiting to get into the game. They can also run lights if the party runs late.

They’re also handy for camping and RVing. Smaller models are perfect for charging devices and running small electronics while hanging out at the campsite. Larger models can power an entire RV’s electrical system, allowing users to stay entertained and comfortable while they’re off-grid.

Home Backup Power

Another popular and effective way to use an inverter generator is for home backup power. When the power goes out, these generators can tie into the home’s electrical panel and supply the entire home with power. Smaller models might not have the power to keep the whole house running, but a few extension cords can keep food from spoiling, provide light, and even run a space heater. 

Professional and Job Sites

Inverter generators are indispensable on most job sites. Since they usually don’t have power until well after the structure is “dried in,” crews can use generators to run power tools, power jobsite lights, and more. 

And, even if the home does have power, it doesn’t mean it has the type of power the job needs or where it needs it. For example, a generator can be used to power a 240v welder or supply power in a remote part of the property where the homeowner wants some sort of site work or improvement. 

Safety Considerations When Using an Inverter Generator

Before you unbox your generator, fill it up with fuel, and fire it up, there are a few safety considerations to understand.

Proper Placement and Ventilation

Most experts recommend placing your generator at least 20 feet from the house. Never run a generator in the home, the garage, or under a window.  Also, beyond maintaining a safe distance from the home, the generator should be positioned so the exhaust points away from the house (make sure it points away from your neighbors’ homes, as well!). This will help prevent carbon monoxide poisoning. 

Also, a generator needs adequate airflow to run properly and stay cool. Placing a generator out in the open is typically sufficient. However, if it’s tucked in between bushes and a fence, behind a tarped wood pile, or any number of other situations, it might not get sufficient airflow. Many DIYers build their own generator sheds with louvers, intakes, and exhausts for these reasons. 

Electrical Safety

Generators produce a lot of electrical energy, so they must be used safely. For one, don’t overload the generator by plugging too many items in or trying to run everything in the home at once. When this happens, there is a built-in circuit protector that will trip to keep the generator safe. To reset, simply unplug the items, hit the reset button, and plug items in slowly. 

Generators should also be grounded to run safely. This ensures that any excess current has somewhere to run (into the ground) rather than damaging the generator or harming the user. A generator can be grounded by driving a steel rod into the ground and then com

Fuel Handling and Storage

When it comes to generator fuel (gasoline, specifically), there are a few tips to keep in mind:

  • Only store fuel in approved, self-venting, and safe fuel tanks.
  • Store fuel tanks 95% full and at low temperatures to prolong the fuel’s shelf life.
  • Keep fuel tanks out of direct sunlight.
  • Add fuel stabilizer if the fuel will sit in the tank for several months or at a temperature over 80 degrees.
  • Only store fuel tanks in a garage, never inside the house.

When it comes to refueling the generator, follow this procedure:

  • Turn off the generator and let it cool for several minutes. Spilled gas can drip onto hot engine or exhaust components and start a serious fire. 
  • Open the cap on the top of the generator fuel tank. 
  • With good footing, lift the fuel tank with both hands, pointing the nozzle into the fuel tank opening. 
  • Press the vent release or nozzle to start the flow of fuel. Be careful not to spill fuel onto the generator.
  • Fill the tank, stopping frequently to check the fuel level to avoid overfilling and spilling.
  • Lower the fuel tank and replace the cap.
  • Give any spilled fuel time to evaporate and dry.
  • Restart the generator once it is safe to do so. 

Frequently Asked Questions About Inverter Generators

How does an inverter generator differ from a conventional generator?

An inverter generator has electronic chips and processors to monitor the draw and throttle the engine up or down according to the demand. 

Also, traditional generators produce straight AC power (the power a home uses), but the quality might not be safe for sensitive electronics. Inverter generators create AC power, convert it to DC power, and then invert it back to clean and stable AC power. In general, this is a safer electrical current. 

Can I use an inverter generator indoors?

No. The only inverter generators that are safe for indoors are solar generators, which don’t use combustible fuels or produce emissions. Using gasoline, propane, or kerosene-powered generators indoors can cause carbon monoxide poisoning. 

How do I calculate the required wattage for my needs?

The process for determining the required wattage for a generator is quite complicated. It involves listing all of the home’s devices, determining each item’s wattage requirements while starting and running, adding these numbers together, and then planning for expansion.

Can I connect two inverter generators for more power?

In many cases, inverter generators can be linked together to increase their output. This does require a brand-specific kit, however, and it can often be less expensive to purchase one large generator than two smaller models. 

How should I maintain my inverter generator for a longer lifespan and optimum performance?

Maintaining an inverter generator involves:

  • Storing it safely away when not in use
  • Adding quality fuel stabilizer to the tank before running the generator out of fuel before storing.
  • Change your spark plug and air filter after 200 hours of use or once per year.
  • Keep the battery on a trickle charger (not all generators have batteries).
