Things To Look Out For When You Are Buying An Inverter Generator

The process of deciding on which inverter generator to buy can get a bit complicated. If you want to get the best inverter generator that will suit your needs, there are some factors you should consider. 

We’ll go into the details of some of these factors.

Power

The first and most significant thing you need to consider is how much power output you will need for the inverter generator to generate. To ensure your power needs, think about the kind of appliances you will power with the generator.
It would be best to consider how many of them you will need to power simultaneously.
Ideally, buying a generator that can produce more power than you need than a generator that produces insufficient power is better.
Wherever you use the generator, it will play a big role in determining your power needs. If you are using the generator mostly for camping, you won’t need much power, but you will need much more if you plan to use the generator to power your home.

Noise Level

Generally, some generators tend to produce more noise than others. Fortunately, inverter generators are usually mostly quiet.
Still, you will find out that some inverter generators are quieter than others.
It is essential that you consider the noise level the generator you want to buy produces. Generally, quiet generators usually have a noise rating of between 45 and 55 decibels.
If you want to enjoy a quiet generator operation, you should buy generators with noise level ratings that range between 45 and 55 decibels.

Parallel Capability

You may end up getting an inverter generator that is not powerful enough to power your appliances. In cases like this, it would be very handy if the inverter had this parallel capability.
This feature allows you to double the inverter generator’s total power output by connecting two identical inverter generators.

Portability

Most inverter generators are usually portable. However, there are still some that are more portable than others. 

When you want to buy your inverter generator, you have to consider the dimension and weight of the generator. You should also confirm if it has handles or wheels to aid easy transportation. 

All of these determine how portable an inverter generator is. Take note that with smaller generators, you may be sacrificing more power output. 

Clean Energy

The cleanliness of an inverter generator can be viewed from two different perspectives. 

Firstly, when an inverter generator runs on certain types of fuel like propane, it will burn cleaner, which means you won’t need to clean the generator too often. 

On another note, clean energy also refers to the stableness of the energy the generator produces. Though inverter generators produce a cleaner source of energy compared to conventional types, some of them produce much cleaner energy than others. 

When your inverter generator produces steady energy, it will protect your sensitive devices from surges. Hence, it is crucial that your inverter generator produces the cleanest energy possible if you are going to be powering lots of sensitive appliances.

How The Review Process Was Done

The basic approach we took to carry out the entire review process involved a lot of Intensive research. It is necessary if you are looking for the best products amidst a wide range of products.
Hence, we took the time to carry out extensive research for you. We started off by performing an exhaustive analysis of the highly-rated inverter generators on Amazon.
We first considered the inverter generators that have received high praise and ratings from industry experts. After this stage, we moved on to compare the products we had gathered.
Some of the criteria we used to gather the generators include how efficient they seemed to be, their Amazon rating, the number of reviews they had, and their general ratings on Amazon.
In this process, we gathered 10 inverter generators that met our criteria as well as the level of quality we were searching for. Moving on, we proceeded to analyze their power capacities.
Since users will have varying power needs, we didn’t limit our choices to a particular power capacity range. However, the fact that we had gathered different generators with different power capacities didn’t stop us from using the metrics to test their performance capabilities.
We accessed and took records of the performance capabilities of every generator on our list. We applied the same test approach to discover how efficiently they can serve as backup power with and without transfer switches.
Another aspect of the test was where we checked to see how each of the generators could handle light and heavy loads. We checked how efficiently the generators could power heavy tools and equipment and other equipment used in large outdoor settings.
In addition, we also checked for the noise level of the generators while standing 25 feet away from them. During this test, we recorded their noise levels when they weren’t under any load and also when they started running under load.
