Buyer’s Guide – Choosing a Generac Inverter Generator

Before you choose an inverter generator, you will need to decide two things:

  • How are you planning to use it?
  • How much power do you need?

For those looking for a backup energy source during a hurricane, an inverter generator is not designed for it. In this case, you need a large, portable emergency generator or a standby home generator. If you only need to power a few things, then a large inverter generator should work just fine.

Typically, an inverter generator is best when used for a recreational activity. Think camping or tailgating parties. This is where an inverter generator will shine.

What is an Inverter Generator?

The Inverter

An inverter generator uses inverter technology, hence the name. It allows you to switch the current from direct to alternating current and then back again. This helps to ensure that you have a consistent power flow to your appliances.

Fuel Efficiency

Inverter Generators are also super-efficient when it comes to fuel. An inverter generator allows you to adjust the engine speed to match the needs of what you are powering. This is a more fuel-efficient design that doesn’t stay at just one speed no matter what it’s powering and wastes a ton of excess power. Think about all the money you’ll save on fuel!

Noise

Typically, a portable generator will have some sort of hum that can be super loud. An inverter generator is a lot quieter thanks to their engines throttling back. When run at low throttle, an inverter generator is about as loud as a normal conversation.

Size

Usually smaller than a portable generator, an inverter generator is also easier to transport in a car or RV.

Maximum Power

A portable generator is able to support more than 10,000 watts over a several hour period. With an inverter generator, you are limited due to their small size, efficiency, and portability. Like a portable generator, an inverter generator provides mobile power or temporary power solutions.

Regular Generator versus Inverter Generator

As we mentioned, the main difference between an inverter and a regular generator is the inverter’s ability to create clean electrical power for sensitive electronics. Here are a few other differences between the two:

Fuel Efficiency

You get a higher fuel efficiency with an inverter in comparison to a regular generator. You are able to change the engine’s speed on an inverter allowing it to produce less current and run slower when you are only powering a box fan. As you add other items, you can adjust the speed to meet the new demand.

With a regular generator, you get one speed, period. No matter what the power demand is, so you end up wasting energy and fuel since it is constantly running on full power.

Output

With a limited wattage range, an inverter generator can only produce about 7,000 watts of electricity. This is a lot less wattage than a regular portable generator that creates up to 17,000 watts.

This is one of the reasons you wouldn’t use an inverter generator for emergency backup situations unless you just need to power a couple of smaller items. Typically, an inverter generator is used for recreational needs when you are tailgating or camping.

Power

Offering a lower total harmonic distortion, inverter generators don’t create a large amount of electricity. If you are looking for a generator to power a TV as you tailgate or to supplement the power supply in your RV, or you need something to power the television at your tailgating party, an inverter generator is the better choice. When you need something to power your entire house, then you want a traditional generator.

Noise

Everyone knows that generators are noisy. After a hurricane, it’s basically all you hear in the neighborhood. Since you can only turn them on and off, they run at full throttle anytime they are on.

However, with an inverter generator, you can have an almost whisper quiet generator thanks to its ability to spool down and up as you need it to. Many inverter generators on the market are actually quieter than a normal conversation. This allows you to have one at a party without worrying about needing to shout to your guests during conversations.

Portability

Since an inverter generator has a smaller design, they are more portable than a regular generator. This is a great feature if you need to pick it up and put it down again, plus it’s a great size for small backyard parties and tailgating.

Cost

If there is one major drawback to the inverter generator, it’s the price. They are more expensive, but if you need them to power personal electronics, it is probably worth the extra cost.

Weight

Most inverter generators weigh less than 100 pounds. Larger inverter generators also come with wheels and a telescoping handle to help maneuver them into place. This is a great option if you need a lightweight and portable generator for small power applications.

Size

A lot more compact than a regular generator, an inverter generator has a more efficient internal design that uses a smaller fuel tank. Many inverter generators weigh under 40 pounds, which makes it easy for anyone to move them around. This also helps make them popular for recreational activities.

Noise Level

Designed to be quieter than a regular generator, inverter generators offer noise levels that are ideal for campgrounds where there is an official noise restriction. Typically, an inverter generator registers around 66 dB, which is about the same noise level as a regular conversation. In comparison, a regular generator measures as high as 76 dB, which is the same noise level as a vacuum cleaner.

Parallel Capability

Inverter generators may not be that powerful on their own, but you can double their power by combining two of them together with a parallel cable. This ability to parallel with other inverter generators will allow you to power larger things like the air conditioning in a home. Not all inverter generators have this ability, but, if it’s important to you, make sure the one you choose has it.


FAQs – Generac Inverter Generators

How Do You Connect an Inverter Generator to a House?

There are several ways to connect an inverter generator to your house. A convenience cord, an extension cord, a manual transfer switch, or a through-the-wall kit. It is actually no different connecting an inverter generator to your house than a regular portable generator.

However, hooking up an inverter generator to your house isn’t that common since it can only power a few items at a time. However, there are some situations where you can use a manual transfer switch in order to connect an inverter generator to your furnace system circuit to provide emergency heat during the winter.

Can You Use Inverter Generators Indoors?

No, you cannot use an inverter generator inside. This is the number one rule of generator safety. An inverter generator may appear harmless and small, but they use a combustion engine that will release exhaust gases that can poison and even kill you.

Remember that you should not use an inverter generator in an open garage, shed, detached garage, under a deck, and within 15-feet of a house. Always keep in mind that people die doing this and using a generator does not have a workaround. There are no exceptions to this rule.

Is an Inverter Generator Worth the Investment?

For their fuel efficiency and convenience, an inverter generator is definitely worth it to keep your sensitive electronics safe during a power outage. While there are more upfront costs, many people it’s made up for in its fuel savings, portability, and quiet operation.


Summary/Conclusion

A Generac inverter generator is a great choice for anyone that needs backup power for a trip, small power outages, or any recreational activity. However, if you need heavy backup power, you should look at portable generators instead. Otherwise, you can’t beat the clean power, quiet operation, and convenience of a Generac inverter generator.
