How Inverter Generators Work
An inverter generator is very similar to a traditional generator model. It starts by producing high-voltage alternating current (AC) power. Once AC power is created, an inverter generator converts it to another form of power called direct current (DC). It then takes an extra step to convert DC power back to its AC form once again.
So why all the back-and-forth conversions? Switching from AC to DC and back again is an inverter generators way of “cleaning” the power, making it safer for your gadgets and electronics to consume. Not only is it safer, but the power created from an inverter generator is more consistent, comparing in quality to a home’s central power system.
If you’re worried about investing in an inverter generator that isn’t powerful enough, choose one that comes with parallel capability. Paralleling a generator involves connecting two inverters for double the power output. For this to work properly, both inverters have to be identical in their wattage.
Advantages of Inverter Generators Over Regular Generators
Aside from the fact that a power inverter generator is unable to deliver power to an entire home, it's an amazing alternate source of power. It's the ideal solution for handling power outages or even just bringing along for football tailgating or a weekend camping trip.
No matter how you plan on using your inverter generator, this machine comes with a lot of advantages over regular gas-powered generators, including:
Buying a High-Quality Inverter Generator
Generator Size vs. Power Needs
The first step in choosing the perfect generator is to decide on the generator size. The size of the generator you choose depends on your specific power consumption usage. For selecting the size, look at each particular model's maximum power output. This number varies across the board, but inverter generators are much more limited on power output than conventional generators.
While a conventional generator can have a max power output anywhere between 3,000 and 20,000 watts, an inverter generator is limited to 4,000 to 5,000 watts at its peak. If you're using this as a backup generator, this number is more than sufficient. To give a bit of perspective, a generator that has a power output of 4,000 watts can power 10 LED light bulbs, 4 fans, a microwave, a water heater, and a laptop all at the same time. Most people can get by perfectly with a 2,000-watt inverter generator.
Fuel Type
An inverter generator runs on fossil fuel like gasoline, diesel, or propane. Even while consuming fossil fuels, this type of generator is much more efficient than the conventional gas model. Although a conventional generator produces much more power, it also consumes much more fuel. When choosing your generator's fuel type, the most efficient type is gasoline. Gasoline is more efficient and, therefore, more money-saving than a natural gas or propane inverter generator, but it isn't quite on par with diesel.
Max Power Output
As we mentioned before, a generator’s maximum power output is measured in watts. There are two wattage values for every product, which include starting and running wattage. The more power you plan on using, the more watts you’ll need. Most people are satisfied with a 2,000-watt inverter generator - this is more than enough if this is meant to be a backup power source. The trick is to figure out exactly how much power you need and then choose a generator based on that number.
Many buyers turn to a generator sizing guide to determine the perfect size. A source called Generator Store says that first “you have to work the amount of watts that the tools/appliances you’ll be running use, and remember that with some appliances or tools the number wattage that is listed on the appliance is not an exact representation of the amount that it takes to run it.”
Noise Level
One major advantage of choosing an inverter generator is that this type is much quieter than the conventional type. A generator’s noise level depends on how the engine is running. With an inverter generator, the engine is designed for minimal movement - which means minimal noise. A conventional gas model involves internal fuel combustion, which is the primary source of all the noise.
That said, some inverter generators make more noise than others. To choose a quiet inverter generator, the trick is to look at the noise rating provided by the manufacturer. This is measured in decibels (dB), and anything above 60dB should be avoided.
Fuel Efficiency, Runtime & Running Cost
Inverter generators are smaller on average than conventional ones, which means they contain a much smaller gas tank. Most inverters have a gas tank ranging from 0.5 to 2 gallons. A model with a larger gas tank, say 2 gallons, will be able to perform for longer than a model with a smaller tank capacity.
The main perk of choosing a generator with a small gas tank is that it is lighter in weight and more portable. Our suggestion is to choose a model that has a higher fuel capacity and longer runtime unless portability is your primary concern. In most cases, runtime and efficiency are more important than a lightweight design.
Build Quality & Durability
A generator that was built with durability in mind will be much more reliable in the long run. In the event of a power outage, reliability is a key feature. Take the Honda 2,200-watt inverter generator as an example. This device is as durable as they come with a sturdy outer casing, improved ventilation for better cooling components, and an oil drain gutter for easier generator maintenance.
Ease of Use
Using an inverter generator is fairly straightforward, but choosing a model with complete user-friendliness is still on the list of buying considerations. There are a few convenience features that can make a generator even easier to use, like a readable gas meter, low oil shut off function, and a low gas shutoff function.
Portability
Investing in a portable power source might mean something different to you than it does to your neighbor. To some, portability means that a carrying handle can easily lift the generator. For others, portability might come in the form of rolling wheels. Just remember that a highly portable generator that is small in size will have a smaller gas tank and a shorter run time.
Price & Warranty
A generator's price tag depends on many things, including the product's power output, size, ease of use, and added features. Whatever you do, try not to be turned off by a higher-than-average cost. In many cases, higher cost means more durability, better reliability, and optimal ease of use. But if you're in the market for a cheap inverter generator, there are some top-rated affordably priced models to choose from. No matter the price you pay, confirm that the product comes with decent warranty coverage.

6. WEN 56125i
Best Value Inverter Generator
Engine Type | Gasoline |
Runtime | Up to 7.5 hrs |
Fuel Tank Capacity | 0.7 gallons |
Wattage (Starting & Running Watts) | 1250W, 1000W |
Noise Level | 51 to 58 dB |
Warranty | 2 years |
An inverter generator with a low power output of just 2,000 watts is still more power than many people need. For those of you who are looking for the best value inverter generator with a minimal amount of wattage, consider the WEN 56125i. This is, without a doubt, the best inverter generator for the money, and part of the reason for this is this machine's low power output of 1,250 watts. The 1,250-watt operation allows this generator to be quieter than most.
Wen, a company that has been in business since 1951, says that the
“60cc engine operates at an extremely quiet 51 decibels (at quarter load from 22 feet away), quieter than a window air conditioner or the average conversation. This limits its invasiveness while hunting, camping, tailgating and restoring back-up power.”
The Wen's clean energy is free from spikes and dips, allowing you to power your sensitive electronics (phones, laptops, etc.) safely and reliably - you'll never have to worry about random fluctuations in power. The gas tank is small, holding up to 0.7 gallons at a time, but it still has a half-load run time of 5 hours and a quarter-load run time of 7.5 hours. There's an Eco-Mode throttle for maximizing the Wen's fuel capacity even further.
All in all, this is a great choice if you’re looking for something portable, reliable, and affordable. The 56125i won’t offer the same mileage as a 3 or 4,000-watt generator, but it gets the job done when needed. If you foresee yourself needing slightly more power than 1,250 watts, this model also comes in 2,000 and 2,250-watt options.

For an inverter generator that is super quiet, super powerful, and super fuel-efficient, you'll want to go with the Westinghouse iGen4500. This is the best 4500-watt inverter generator on our list of inverter generator reviews for so many reasons. Aside from being easy to use, the iGen4500 comes will loads of added features, like remote start, RV-readiness, and an economy mode setting for better fuel efficiency. The feature we love most is the machine's remote start.
Westinghouse says that this
With this feature, there’s no longer a need to leave the house, RV, or tent to start the generator. This is an ideal solution for RVs since it comes with all the adapters that are needed for use in a recreational vehicle. It's strong enough to power all the essentials and always provides clean and safe power without fluctuations in voltage or frequency. Oh, and did we mention that the iGen4500 has a run time of up to 18 hours and a noise level as low as 52 decibels?
The only downside is that this is not a parallel capable generator. This means you won't be able to double up on power by connecting two iGen models. Parallel capability is a fairly common feature these days, but this generator doesn't allow for that. The upside is that 4,500 watts is plenty for the majority of people, so it is very unlikely that you'd need more than this.
Pros
Cons
8. Pulsar PG4000iSR
Best 4000 Watt Inverter Generator

Fuel Tank Capacity | 3.4 gallons |
Wattage (Starting & Running Watts) | 4000W, 3500W |
Noise Level | 63 dB |
Warranty | 2 years |
We've covered a wide range of wattage so far - everything between 1,250 to 7,000. If you're looking for something that falls in the middle of that range, a generator with a wattage of 4,000 is just right. The best 4000-watt inverter generator is the Pulsar PG4000iSR. This model comes with a 3.4-gallon gas tank, allowing it to run up to 15 hours at half-load operation.
Similar to the iGen4500, the PG4000iSR comes with an easy-to-use remote start feature. The wireless remote start allows a user to operate the generator from more than 80 feet away. Another cool convenience feature is the electric push start. No matter if you choose to start the machine from near or far, you can do so with the push of a button.
Pulsar takes pride in all of its generator products, which is made obvious by the company’s PG4000iSR product description:
“The PG4000iSR Portable Inverter Generator is a versatile and rugged source of alternative power for any occasion. With 4000 Peak Watts/3500 Running Watts and up to 12 hours continuous operation on just 3.5 gallons of fuel, the PG4000iSR is both a practical and powerful choice for your next outdoor event.”
One downside of choosing this 4,000-watt generator is that it is a bit on the noisy side. It’s still much quieter than a conventional gas-operated generator, but the 63-decibel noise level is high compared to other products on this list. Another negative feature is the generator’s weight. This machine nearly weighs 100 pounds, so it requires 2 people to lift. The upside is that it comes with a rolling suitcase design, so lifting the generator is only necessary on stairs.
Pros
Cons
9. Generac GP3000i
Best 3000 Watt Inverter Generator
Engine Type | Gasoline |
Runtime | Up to 5.8 hrs |
Fuel Tank Capacity | 1.06 gallons |
Wattage (Starting & Running Watts) | 3000W, 2300W |

Warranty | 3 years |
If 2,000 watts is not enough, but 4,000 watts seems like overkill, consider the best 3,000-watt inverter generator, like the Generac GP3000i. This super-quiet machine uses PowerRUSH technology that delivers over 50% more starting capacity (up to 5,500 watts). It has all the must-have features of a portable inverter generator, including an Eco-Mode setting, an easy-to-carry handle, parallel capability, and reduced sound emissions.
One thing we love about the GP3000i is the simple control panel. This is where you’ll find the PowerDial knob that offers 3 integrated settings (Choke, Run, and Off) in one easy-to-use dial. The panel is also equipped with 2 USB ports, 2 120V AC outlets, and a parallel outlet for connecting 2 GP3000i units together for double the power.
Although there is no LCD screen on this generator, the control panel comes with generator status lights that provide “visual alerts when unit is low on oil, overloaded or ready to use.” Some users prefer monitoring updates from an LCD screen, so if that’s the case you’ll have to look elsewhere. The other downside is that you’ll have to purchase a parallel kit separately if you plan on connecting 2 generators for twice the power.

Additional Inverter Generator Features
Fuel Gauge
An inverter fuel gauge is a handy feature that allows a user to read the exact amount of fuel that remains in the tank. With an accurate fuel gauge, there’s no guesswork on how long a generator can run.
Eco-Throttle/Eco Mode
A generator that comes with an eco-throttle feature does not run the engine at a constant speed. Instead, it uses smart-throttling methods to conserve fuel whenever possible. This function can help to reduce fuel consumption by up to 40%.
Remote Start
Similar to remote starting a car, the remote start functionality in a remote start inverter generator allows you to turn the machine on from a remote location. If the generator is located outside and you're feeling overly content on the couch, simply push a button to get the generator up and running.
Parallel/Tandem Operation
Many modern generators have parallel capabilities, which means they can pair up with an identical model to double the power output. Investing in two portable, lightweight inverter generators with tandem operation is a fantastic alternative to buying a heavy and inefficient conventional generator.
Manual Fuel Shutoff Switch
A manual fuel shutoff switch is an important safety feature to look for in your new inverter generator. This allows you to turn off the fuel but also keep the engine running, which prevents damage and issues caused by stale fuel.
Low-Oil Auto Shutoff with Indicator Light
This feature helps you to keep tabs on oil and know exactly when it's time for an oil change. Not only is this a helpful safety feature, but it also helps to keep the generator adequately maintained.
Determining Power Needs - Sizing Inverter Generators
To choose a generator that is the right size for you, the first step is to determine your power needs. We're not talking about coming up with a ballpark figure for the number of watts you think you need from a generator. There is a much more accurate method for calculating your exact power usage and the generator power output that it requires.
Consumer Reports says that when going through the calculations for choosing generator size,
“simply add up the wattage of everything you want to power during an outage. Before you bust out the calculator, keep in mind that some appliances—air conditioners, refrigerators, and sump pumps, for instance—draw more wattage momentarily when they're cycling on.”
A 2,000-watt generator is a solid choice if you only plan on using this device during power outages. It's lightweight, cost-efficient, and there is no installation and assembly required. It provides enough wattage to power a fridge, a few light bulbs, and maybe a phone charger. If you plan on powering anything else, you'll want to go with a higher wattage, like 3 or 4,000.
Importance of a Generator Transfer Switch
The purpose of a transfer switch is to switch over your home’s energy supply from the utility company to the backup generator. According to Mr. Electric,
“it isolates the generator from municipal power lines to protect utility repairmen from power surges caused by backfeeding. This essential piece of safety equipment is required with all wired-in backup generator installations in all 50 states.”
There are two types of transfer switches, automatic and manual. An automatic switch is the better choice since it won’t have you fumbling around in the dark as soon as the power goes out, but a manual switch is much cheaper to install. No matter which one you choose, investing in professional installation is a must - this is by no means a DIY project since it requires electrical work.
Installing Inverter Generators
The first thing to remember when installing your inverter generator is never to use it indoors. Even though it is highly efficient, it still uses gas to operate, so indoor use is a big no-no. The generator should only run while away from the house - even porches and decks are considered off-limits.
According to Popular Mechanic’s home generator 101 guide, the next step after deciding on safe placement is to
“run an outdoor-rated extension cord from the machine to the appliances you want to power or use a generator cord to connect to a transfer switch like this one.”
This same guide provides some helpful safety precautions, such as:
People also Ask (FAQs)
What does load sharing mean in inverter generators?
Woodstock Power Company says that generator load sharing is
“crucial to understand when attempting to parallel generators at any facility...different manufacturers’ load sharing controls may not be compatible and overloading or underloading each unit must be avoided for successful and efficient generator paralleling.”
There are several load-sharing methods, including:
- 1Cross Current Compensation
- 2Droop Load Sharing
- 3Use of Different Operating Modes
What is generator synchronization?
It is used to connect and synchronize things like voltage and frequency between a generator and a home’s power system. Without synchronization, everything would be out of whack. All modern inverter generators are equipped with an automatic synchronizer, so you won't have to do anything manually.
