Vital Guide to Find the Best Inverter Generator
You’ve made the choice of which type of portable power source best fit your needs. Whew! But now you’re trying to decide on which is the best portable inverter generator. The decision can be easy, you just need to answer a few questions that will help you narrow down all the inverter generators on the market to just one that is suitable for you.
Things to Consider Before Buying – Needs, Features, Price
If you’re reading this, you’re the type of person who wants to have all of the information in front of them before making a purchasing decision. In that case, consider the following as you narrow your choices.
Where Do You Intend to Use Your Inverter Generator?
Believe it or not, deciding on your power requirements and where you intend to use your generator is important. Each place you intend to use your inverter generator can influence which one you’ll want to purchase.
- Home Back-up Power: This comes down to what you need to power in an outage event. If you just need your phone and a coffee pot, something as small as 1000 watts will suffice. However, if you need to power your electric garage door and sump pump; you’re going to need something much bigger.
- RVs and Cabins: For an extended off-grid living, you will want an inverter generator capable of running at 2000 watts or higher. Running your entertainment devices and appliances simultaneously requires quite a bit of power. There is another feature you may find necessary is the ability to link two or more inverter generators together; allowing you to still have the portability of an inverter generator while achieving higher power output.
- Camping: You need to decide what you want to power and for how long when buying a portable power source for camping. A lot of times you won’t need a very big power source for camping; as there isn’t much that needs electricity in the middle of the woods. A 1000 watts or less should be ideal.
Long Run Time – Think Gas Efficiency
The majority of inverter generators will have a 0.5 to 2.0 liter of a gas tank. When it comes to runtime, portable power sources have a bit of a trade-off. More run time means a bigger gas tank means less portability. More portability means less gas tank and less run time. So weigh out your options, and if given a few pounds difference over runtime, always take the runtime.
Portability – Light Weight or With Wheels
With portable power sources including inverter generators, portability means different things to different people; some want to be able to lift their power source, while some will trade weight for more power and wheels. Choosing what kind of portability you want, and what you’re willing to give up in exchange for that, is important. Personally, I would trade the ability to carry my inverter generator for being able to run my electronics longer, but it all goes down to personal preference.
User-Friendly – First Time Using a Portable a Generator
If you’re not familiar with the ins and outs of these sorts of machines, you will want a machine that has some user-friendly features, such as;
- Low oil shut off
- Low gas shut off
- Gas meter
Most inverter generators now come standard with these options. But always check to make sure.
Noise Level – You Don’t Want to Keep Your Neighbors Up All Night
While inverter generators are significantly more quiet than regular generators. However, there is a big difference between one machine and the other. As a result, it’s important to look at the noise rating of the inverter generators on your list. While that may not be a deciding factor in your purchase, it’s definitely something to keep in mind. You can measure noise in decibel (dB) for portable power machines. And anything above 60 decibels at 50% load for an inverter generator is higher than average.
Price – What You Need Can Fit Your Budget
If you’ve already decided on an inverter generator as your portable power source of choice, then I’m sure you’ve seen their cost. Inverter generators are more on the expensive side than conventional generators. But an inverter generator is a much more versatile, much better quality, and in many cases, much easier to use portable power source.
The price of owning an inverter generator is a bit higher than owning a regular generator. But as shown by the steady increase of popularity that these portable inverters have achieved, many people are deciding that they’re worth it.
Watch Out – Avoid These Mistakes When Buying an Inverter Generator
Avoiding these mistakes will ensure you get the right product, at the right price.
- Be aware of industry jargon, and only focus on the specifications of each machine. If you were selling a cake, you would say it was the best cake ever, even if it wasn’t.
- Get a machine manufactured by a well-known company. If you look all over and no one has heard of the company – don’t purchase from them.
- Make sure you get a good warranty. If two machines match your needs, then check the warranty. The one with the best warranty is always the best choice. A warranty is a great sign of how a company feels about their product.
- Price check. Check around and see if the price you’re getting is really the price that you should be paying for. Usually, buying online will save you money.
Making Your Choice
Now, you’ve decided on the features that are important to you, what you need to power; as a result, the size of the inverter generator you need, what a reasonable noise level is, and lastly which inverter fits within your budget. The only thing left is buying one.
The biggest thing to keep in mind as you make your choice is that while there are many great options out there, no one can say which one is ‘best’; because the best inverter generator for me could be annoying and inconvenient for you, and vice versa.
To get the best performance from your portable generator, you can check our list of the most useful accessories for a portable generator.
What Makes an Inverter Generator Special?
The terms ‘generator’, ‘power inverter’, and ‘inverter generator’ are commonly used, but there are marked differences between these machines and their functions and abilities. To know what makes an inverter generator different from both inverters and regular generators. We’ll need to take a look at what each of them does.
A generator is a fuel powered motor attached to an alternator and that produces electricity. The motor of a generator has to run at a constant speed to be able to produce the current required.
The New Generation Inverter Generators
Inverter generators use a 3-phase system. They create AC power like their generator counterparts, but then that power is converted to DC, and then ‘inverted’ to create pure sine wave electricity. Sine wave energy is considered superior to the regular energy common with generators. Primarily because sine wave energy doesn’t experience the spikes and dips in current that happens in regular generators. This makes it safer to use inverter generators with sensitive electronics, such as your digital cameras, smartphones, and sound systems.
Unique Features of Inverter Generators
Inverter generators are uniquely useful when compared to regular generators and inverters, and have many advantages not found in their counterparts. When looking for a portable power source, there are key features to look for, and an inverter generator is many times more likely to fit your portable power needs.
Safe Energy for Sensitive Electronics
Many times, when searching for a portable power source; you’re looking for something versatile, and often for something to use as a backup power source for your home or a portable power source for camping, RV’s and cabins. All of these usages have one thing in common; you’re going to power sensitive electronic devices, such as laptops, phones, tablets, GPS navigation system, and so on. Using a regular generator poses an innate risk to these types of electronics; due to the unstable nature of the power regular generators produce. Making inverter generators much safer to use due to their power quality.
Convenient Portable Power Source
In this age of instant gratification and the constant search for convenience, inverter generators make more sense to own when compared to inverters and generators. They have their own power storage system (battery), they’re safe to use with sensitive electronics, such as computers and tablets. So, you don’t have to worry about damaging them, and they don’t need special conditions to run (such as solar panels, in the case of inverters).
Cost of an Inverter Generator
Many of us know that convenience comes at a cost, and the same is true for inverter generators. Possibly the only disadvantage of an inverter generator, as opposed to a generator or inverter, is the purchase price tag. The cost of inverter generators usually tends to be higher than conventional generators. However, they carry distinctive characteristics, that makes them worth the higher price tag.
At the end of the day, only you can decide if an inverter generator is the right portable power source for you. But with convenience and features available with inverter generators, they are becoming the preferred source of portable power.
When Does an Inverter Generator Top a Conventional Generator?
Conventional generators and inverter generators both have their place in the world of portable power machines. With our inverter generator reviews, you’re able to see which ones are the best in their class. But even the top-rated inverter generator can’t take the place of a conventional generator in some cases, and vice versa. That leaves us with the question, “When does an inverter generator top a conventional generator?” To answer that, we need to check the difference between the two. Inverter generators vs. conventional generators.
The general makeup of a generator, a fossil fuel driven motor wired to an alternator. Once the alternator is running, it produces electricity, similar to the way the engine and alternator work in your car. But the motor of a conventional generator has to run at a consistent speed, for it to produce the current required to run AC electronics. Conventional generators come in enormous sizes, upwards of ten thousand watts for commercial models. To put it in perspective; a commercial generator can be big enough to power your entire house, fridge, flat-screen, PlayStation and all.
Inverter generators are a bit more complicated than conventional generators; they use a 3-phase system. As with generators, inverter generators create AC power. But that’s where the similarities end. Inverter generators then convert the power to DC, which may seem a bit counter-intuitive. Once the power is in DC form; they invert that power to create sine wave energy – a much more stable type of power. Sine wave energy is considered a much more stable form of electricity. But inverter generators only get so big, typically maxing out at under 6000 watts.
Features in Inverter Generators that Top Conventional Generators
Features are going to prove the main difference between inverter generators and conventional generators.
- Size: Inverter generators make portability a primary manufacturing goal. And are often found in sizes around 24 x 13 x 15 inches, some can be bigger, some smaller, but they average around this size. Conventional generators lack the convenience of their smaller counterparts.
- Weight: It’s not unusual to find inverter generators under 75 pounds, sometimes much lighter. While you can find small open frame generators, inverter generators are most often lighter.
- Fuel: While generators typically have larger tanks, inverter generators are much more fuel-efficient; due to their ability to automatically adjust output based on load.
- Noise: This is probably the biggest functional difference between these two types of machines. The average inverter generator is rated about 61 decibels at full load. To compare, an electric razor is rated at 68. Can you imagine? Alternately, conventional generators are rated at 65-75 decibels – the same range where jet engines are listed. This matters for many reasons, not the least because that level of noise constantly running could be intolerable.
- Power Output: Generators come in almost any size you can imagine; from a few hundred watts to over fifty thousand. Most inverter generators tap-out at under six thousand watts.
- Type of Power: In the age of smartphones and computers; our precious electronics are often the reason we buy backup power equipment or portable power equipment for camping. As we discussed above, generators experience a lot of dips and surges in their power output. Whereas inverter generators provide a constant and consistent output of power. The result is that charging your smartphone with a conventional generator could fry its sensitive battery; where on the other hand, charging it with an inverter generator is safe.
Occasions an Inverter Generator would Top a Conventional Generator
- Camping: An inverter generator can quietly power the devices you need to run.
- RVing: You will need something quiet because most campsites have enforced noise restrictions between certain hours of the night.
- Cabin: You’re probably going to want to plug in your phone, laptop, or portable electric stove, whether you’re in your cabin or boat. You wouldn’t want to listen to the ever-present roar of a generator.
- Emergency Backup: You will need a stable, quiet power source to power a few basic electronic devices and appliances.
Unless you have a need for a large source of power, an inverter generator is nearly always the best route to go. It provides the quiet, stable, safe electricity you need in the most efficient way possible. They’re easy to transport, highly portable, and need very little monitoring. Our inverter generator reviews cover the features and benefits of different models and sizes; allowing you to find the best portable inverter for your needs.
