Best Inverter Generators Buying Guide

When it comes to selecting the best inverter generator, there are several factors that you will need to consider beforehand. Considering the following criteria will prove beneficial when scouring the market and selecting the generator that is worthy of your purchase.

The Wattage

The most important factor to consider is the wattage of the generator. Just like other generators, the wattage of inverter generators can differ between models.

An inverter generator with a higher wattage is going to produce more power and this is often reflected in the size of the unit. A generator with a lower wattage is going to produce a lower amount of power.

It is important to consider your needs as those with a lower rating are better suited to lighter use. Those with a 3,000 to 4,500 rating are better suited to medium use and those with a larger rating can endure heavy use like powering the entirety of a home.

You will typically find generators capable of such work are going to have a rating that exceeds 4,500 watts.

Parallel Capabilities

The parallel capability refers to the ability to connect two identical inverter generators to double the amount of power. This is going to come in handy in instances where you feel as though you need more power.

You will typically find that most are parallel ready with generators from the same brand of which are the same size. It is important to note that not all generators are parallel ready so it is important to assess the specifications of your generator to see whether it is equipped with this feature.

The Noise Level

Inverter generators tend to be much quieter when compared to their standard counterparts. You will find that most claim to produce a maximum of 50 to 60 decibels when in use.

It is important to be considerate of your surroundings depending on where your generator is going to be used.

If your house is located in a more isolated area, this may not be a significant concern, however, if your generator is going to be used on a campsite you will need to consider those who will be near the generator.

Some campsites and RV parks have strict regulations in place concerning the noise output that they allow.

The Size

For some, the size of the generator is an important factor to consider. As mentioned, you will often find that larger units have a higher watt rating.

If you are likely to require the use of your generator at a campsite, or RV it will need to have a portable design that will allow you to transport the unit between locations with ease. 

Most inverter generators are lightweight and for this reason, they aren't going to provide you with challenges when attempting to maneuver the unit. Transporting the generator is also going to be made easier by the addition of wheels or handles.

Production of Clean Energy

Inverter generators are often sought after for the clean energy that they produce. Not only are fuels like propane going to burn cleaner, the production of this stable and clean energy means that the generator can power sensitive electronics and appliances.

Inverter generators differ pretty significantly from conventional generators as they are subject to less harmonic distortion. If you are going to be powering sensitive electronics the production of clean power will ensure that they do not become damaged.

The Power Outlets

The power outlets can be found on the body of the generator. A unit with more ports will allow you to power more appliances at once. If your generator lacks a sufficient amount of ports you will need to prioritize the appliances which require power first.

When using their ports it is important to ensure that the generator is used according to its maximum wattage capabilities. Even if the generator sports multiple ports, those with a lower rating aren't necessarily suitable for charging a lot of appliances at once.

EPA and CARB Compliant

You will find that the specifications of many generators state that they are EPA and CARB Compliant. As such, they produce clean energy and run much smoother.

You will typically find that most generators are both EPA and CARB compliant.

Additional Features

Many generators have additional features that provide greater convenience for you as the user. In some cases, this may refer to an electric start function that allows you to operate the generator with the simple click of a button.

Some will also feature an eco mode that maximizes the fuel efficiency while also lengthening the run time of the unit. You will also find that many generators come with a manual shut off switch that allows you to stop the generator from operating with the simple click of a button.

Others will do so automatically once they have recognized that the fuel and oil have dropped below a certain level.

The Price

Inverter generators tend to be more expensive when compared to other standard units. This is because they utilize modern technology while promoting improved fuel efficiency.

While it is worth having a budget in mind, you must ensure that your chosen generator features all of the functions that you require, otherwise it is going to prove ineffective in fulfilling its purpose. 

Frequently Asked Questions

Are inverter generators worth the money?

Inverter generators are equipped with several favorable features that many would consider make them worthy of purchase.

While they are one of the more expensive offerings on the market they tend to compensate because of their fuel efficiency.

How big of an inverter generator do I need?

To determine the size of the generator that you require, you must first evaluate the appliances that it is likely to be powering. If you are going to be using your generator on the go or inside your RV, you will likely find a 3000 to 4000-watt generator sufficient.

Most household appliances such as a fridge or freezer can be run on a 5,000 to 7,500-watt generator. If you want to run all these appliances at the same time, you will likely benefit from investing in a 7,500-watt generator. 

How long do inverter generators last?

The quality is going to be one of the main factors that determine how long your generator is going to last.

As such, a generator of this kind can deliver approximately 1000 to 2000 hours of use and is likely to last for around 10 to 20 years.
