What Is An Inverter Generator?
Standard portable generators and inverter generators may power the same devices, but they do not function in the same way. An inverter gets its name from the process that happens when you turn the generator on. The machine converts the voltage using a microprocessor from to DC and then “inverts” it back to AC current.
In the end, you’re still getting the same output of AC electricity that a conventional portable generator provides, but without the same surges and fluctuations that a standard generator sees. By converting the electricity back and forth, the machine ensures that the power you’re getting is “clean,” creating a perfect sine wave of energy. That lowers the risk of power surges, which protects devices and creates more stable energy.
How Does An Inverter Generator Work?
The name “inverter generator” comes from the electrical work the generator is doing when it’s running.
Inverter generators transform DC power to AC power, eliminating any fluctuations that come with it. The generator's alternator produces high voltage power that gets converted to DC, which is then shifted to AC by the inverter.
When it's fired up, an inverter generator throttles the engine to meet your backup power demands. That makes for a more "stable" output of power when it's running. The power that comes with an inverter generator is considered high quality but remains smooth and clean.
Inverter VS. Generator: What's The Difference?
The main difference between these two types of generators is how they run. When you run it, an inverter adjusts its power level based on the devices it's feeding. Instead of running at a constant speed, an inverter is continuously adapting its speed.
That's not the case with a conventional generator. They need a certain speed to deliver 120 volts of electricity — typically 3,000 RPM — and keep a stable current. After getting a boost from your preferred fuel (the most typically used power source), the motor works with the alternator to produce a steady output of electricity.
If your conventional generator’s engine speed changes at all, you’ll notice it. That fluctuation will result in a vacillation of the frequency of electrical output.
The other main difference would be the portability. An inverter generator is smaller, lighter, and may even have wheels, making it easier to bring on the go.
Conventional VS. Inverter: Which Is Better?
There’s been a long list of advancements generator technology lately, which may leave you wondering exactly what an inverter generator is, compared to a standard generator. There are several reasons that an inverter might have more advantages than a conventional generator.
Because the inverter generator is continually varying the amount of power it is generating, its efficiency is higher, and it is generating cleaner electricity. You probably won't need as much fuel, because you won't be burning through it as fast.
With an inverter, there's also less technical maintenance required—unlike conventional generators, they don't need any special treatment for standard upkeep. They can be more easily paired with other units for parallel capability without a new transfer switch connection.
They also generally run quieter than your standard generator options, are more lightweight and portable.
Inverter Generator Features
What are the features that make an inverter distinct compared to other types of generators on the market?
- Design And Output: Inverter generators are designed with portability in mind. In most cases, they’re manufactured to have a closed design that is more convenient to move. That limits them to a slightly lower maximum output, but they’re still plenty powerful for most jobs.
- Safe Energy For Sensitive Electronics: Our sensitive electronics are often the ones we use most. That means our inverters have to be up to the task of powering them without putting them in danger.
An inverter’s energy output doesn’t fluctuate or surge as much as other generators. Closer to a perfect sine wave, inverter generators protect your delicate electronics from power surges that can fry them over time.
- Suitable For Noise Restricted Areas: Most inverters sit between around 61 dB or slightly louder than a normal conversation. That means your inverter generator can run in more places without worry about noise restrictions.
- Better Fuel Efficiency: A gas and propane inverter generator dynamically responds to the load it’s working with, meaning it adjusts the fuel need accordingly. As a result, there’s a marked difference in how fast a traditional generator burns fuel compared to an inverter.
- Parallel Operation: Some inverter generators can connect to another inverter and double their power output using a special cable. Since inverters run smaller and quieter than other generators, that makes it easy to increase your power demands on the go.
- Portability: New inverter generators are quite light, as low as 30 pounds in some cases. Those small engines are more compact than their conventional counterparts. Given how quiet the generators run, they're easy to run and power your devices no matter where you need to go.
- When You Need A Lot Of Power: If you're hoping to power every device in your house during an emergency outage, you'll need more than the inverter can provide. Inverters are designed for powering select appliances, or on a camping trip. Inverters do, however, allow for parallel capability, allowing you to double your output.
- When Price Is Not An Issue: Though inverters have a higher price point than other generators, reviews suggest the features are worth the price—and we agree. An inverter provides many advantages to conventional generators, including that they’re more fuel-efficient and portable than other types of generators.
Considerations Before You Buy
1. Where Do You Plan To Use Your Inverter Generator?
Where you depend on using your generator can drastically alter the best inverter for you.
- Camping, RV
If you're camping or living in an RV and need to move around a lot, it might be more advantageous to find an inverter generator that is easy to maneuver. That may leave you with a smaller engine and power output.
For camping, that might be fine, since most of what you need to run (a camping stove or charging devices) 1,000 watts or less should be ideal. With an RV, you may require a little more juice for your plugin appliances, which might set you up with a mid-range inverter (with can power between 2,000 to 4,500 watts).
- Home Back Up
In the event of an emergency situation die to an outage, you’re going to need a lot of power to support the vital machines and appliances in your home. Most large inverter generators top out at 7,000 watts, which should cover the key devices until the power returns. If you hope for more than that, it might be time to look into a bigger, more conventional generator.
- Work Sites
To keep midsize power tools functional at a worksite, you're going to want an inverter with a range of 2,500 to 4,500 watts.
2. Noise Level
The closer you plan on being to your inverter while it runs, the more important it is to be prepared to prioritize volume in your selection. Keep in mind that many generators may boast a quieter speed only to be louder when dealing with a heavier load.
3. Parallel Capability
Parallel capability is simply running two generators together. Often these are the same brand and size inverter, and the effect is that you double the power.
Not all inverter generators can do this (or do it well), but if you find you an otherwise perfect model that lacks power, this might be a good technique to explore.
4. Clean Energy
The cleanliness of an inverter generator could be considered two things: Certain types of fuel (like propane) will burn cleaner, so you don't need to clean your generator as much, but it also refers to the stableness of the energy source. When inverter generators produce a cleaner sine wave (meaning a steadier source of energy) that protects your devices from surges.
If you plan on using an inverter to power delicate electronics — televisions, computers, and other things with a microprocessor that makes them sensitive to electrical quality — it's crucial to have a generator that can provide the cleanest energy possible.
Avoid These Mistakes When Buying An Inverter
- Stay focused on how the specifications of the machine can actually serve you and don’t be swayed by flowery language or overpromising on the part of the manufacturer.
- It’s probably better to buy an inverter from a well-known brand, especially if you’re new to inverters. Their customer service is more reliable.
- The best inverter for you won’t necessarily be the most expensive. Compare the price at different places and see if you can get everything you need while staying within your budget.
- If all else is equal between two inverters, let the best warranty win.
Frequently Asked Questions
Are Inverter Generators Worth It?
We would say so! Although inverters come at a more premium price compared to conventional generators, they are much more adaptable. They’re quieter and more efficient — and, these days, equipped with the latest technology to keep them both those things as well as easy to use.
Unless you’re looking to power a whole lot in an emergency, inverters manage to more than get the job done. Even better, because they provide more stable, fuel-efficient power, you can likely count on making your money back in the long term.
Can An Inverter Run A Fridge?
They can, though not all of them. You'll want to look at least the midsize range (2,000 to 4,500 watts) if you’re hoping to power a fridge in an RV or a home.
Why Are Inverters So Quiet?
There are a few reasons that inverters are considered quieter than their conventional generator counterparts. Their engines are generally smaller and more responsive to the load, meaning they both produce less noise and don’t run at the same rate when they’re on. Inverter generators are also enclosed, which muffles the noise even further.
Can You Use An Inverter Indoors?
You should not use it indoors, as the exhaust from a generator can be dangerous and deadly in enclosed places. An inverter generator should always be placed outside to let the fumes properly vent.
Can You Get An Inverter Wet?
Getting an inverter wet can increase the risk to both you and your generator. If you plan on leaving it outside (and opening it to elements like rain), keep it under a tent or tarp to lower the risk of shock or damage in the device.
When you're buying an inverter generator, it's crucial to think about the situations you will — or may want — to use it in. Though there's plenty of inverters on the market, the one that's "best" will be so because it's the most convenient for you.
The best way to go about shopping for an inverter generator is to establish what features you want and need most. Every generator on this list can provide a good amount of stable power once you start it up, and you can trust that you’ll be able to use it for at least nine hours. But that is certainly not the only thing you need to take into serious consideration when you’re purchasing an inverter.
