Deciding which are the top 4500 Watt Inverter generators was a difficult task. It took us weeks to go through all the inverter generator models available in the market. Then, we analyzed the features present in them and discarded those inverter generators that had below-par advantages to offer.

Next, we checked the customer reviews and shortlisted only those that had the happiest customers.

Here are the top five 4500 Watt inverter Generators:

Factors To Look For Before Buying a 4500-Watt Inverter Generator

You should consider some points or factors before you buy an Inverter Generator. Not every person can be happy with the same model. So, you must always look for some factors before you decide which models suit you the best.

These are:


Fuel is an important factor to look for before buying a 4500 inverter generator. Generally, three types of fuels are used to run the inverter generator:

  • Diesel
  • Gasoline
  • Propane

Check the current prices of the fuel in your state before purchasing an inverter generator. Buying an inverter generator that runs on affordable fuel is crucial to keep it running.

Tank Size

Tank size is another factor you should consider. If you frequently or continuously have to use the generator, then go for those that have a big tank size.

A tank size of four gallons should be enough in that case. However, keep in mind that bigger tank-sized inverter generators are expensive.

But if you only have to use the inverter generator sometimes or for a shorter period, then a less tank-size generator will be good for you.

Noise Levels

Imagine spending thousands of bucks on something that produces irritating noise. So, before you buy any Inverter generator, check how much noise decibels it emits.

The noise levels should be less than 65 Decibels. If there are more than that, then the generator will cause noise pollution in the neighborhood, and maybe the cops will visit you more often on your neighbors’ complaints.


You should also check whether a brand is offering a warranty on its product or not. If it is, it means it is confident that its product is of top quality. Generally, brands offer two-three years of warranty.

You should avoid buying products from such a manufacturer that does not offer any kind of warranty. Such manufacturers are mainly selling low-quality products that stop working within a few weeks.

If the warranty is for a month or two, then you should avoid buying that machine as well.


An inverter generator with great portability brings great peace. Go for such inverter generators that have wheels that actually work or at least have an ergonomic handle to push them.

Inverter generators weigh more than a hundred pounds on average. If the portability is not good, then you will have to either lift this much weight or push it. In either case, the chances of you getting sore arms and a painful spine are more.


Well, it is hard to predict which inverter generator is durable and which is not. But you can make a guess that machines manufactured by credible brands must be durable. And indeed they are.

When you look at the reviews of the inverter generators described above, you will find that most of the customers are happy with the product because of the features like durability. The reason is that these brands are reputable and are already trusted by thousands of customers.
