Finding The Best Inverter Generator Engine

Every time a power outage happens or you want to go on a camping trip; you may wish that you had a generator or you may need to replace your current one. Either way, with the vast amounts of different generators available, it can be challenging to choose the best one for your needs. A generator is basically an engine that will provide you with electricity.

The process of purchasing a new generator can be a daunting one, but you can take control and figure it out without any serious damage. Reading this blog will be the excellent place to start.

It will provide some general information needed for purchasing a generator and some of the main features of ten popular generators to guide you in your purchase. When you are finished here, another idea is to check out the reviews and other articles associated with generators that are included on this site.

Correct Size

Before you get started, one of the most important steps is to figure out how big of a generator you will need. Many experts have a variety of opinions on how to calculate the proper size of generator that is required.

Some experts think you need to calculate the precise number of watts used by all of the appliances in your home. While this is ideal, it not feasible to know the exact amount needed for older devices.

Some suggest forgetting about adding and just deciding on a small, medium, or large unit depending on the size of your house. This technique can save time, but it also can lead to extra money being spent on a large generator when you only need a small one. It can also result in you purchasing a small unit when you need a medium.

Fortunately, this site provides a place where you can calculate the exact wattage you need. With this number, you can then get in the ballpark of a suitable generator for your desires.

Type of Generators

Generators come in a variety of shape and sizes. The two most common types are standby and portable.

Standby generators can run from 7,000 to 20,000 watts to protect your home 24 hours a day seven days a week from a blackout. When an outage happens, a standby generator automatically turns on and stays one until the power is restored.

The standby generator is professionally installed and is stationary. It is fueled by natural gas or propane similar to your furnace or water heater. These generators are fully enclosed and come in a variety of styles and sizes.

Portable generators can be moved where they are needed. For example, they can be used for a camping trip, a job site, a limited supply of emergency storm power for your home, and a multitude of other places.

Portable units can offer from 1,000 to 10,000 watts of power. They typically provide clean power and are quieter than standby units. Portable models can be fueled by a variety of sources which include gas, propane, diesel, etc. One common type of portable generators is the inverter design which will be the focus of this blog.

Inverter Generators Explained

The new inverter generator was recently introduced to the generator world. It works by:

1. Producing high-voltage AC power
2. Converting this AC power into DC voltage
3. Converting this DC voltage back to clean AC voltage

These steps can be complete by using a unique circuitry that allows for this multistep process to happen. The AC power created by the generator in the first step cannot be directly used.

So, this raw electricity must be changed to direct current. The DC is then changed back into alternating current in sine instead of block waves. This power can then be used for sensitive devices such as medical devices and microwaves without the fear of damage to the apparatus.

Benefits Associated with an Inverter Generator

All generators provide electricity when it is needed. This technology has been known to be bulky and loud, but the inverter technology has changed the face of the generator.

The inverter technology offers six benefits that standard or conventional generators do not. Most inverter units have the capability to change the speed of the engine. This ability allows the engine to produce the exact amount of power needed which conserves energy.

On the other hand, most conventional models constantly run at 3600 RPMs which may provide power that is not necessary which wastes fuel.

Conventional generators cannot produce the same level of clean power that an inverter generator can. The power generated by an inverter model is almost exactly the same as the power output of your home lines. This similarity means your devices are as safe with this type of unit as home based power.

When you own a conventional unit, you must conduct maintenance every single month. With an inverter model, you typically only have to service it once a year.

Two identical inverter generators can be paired together to produce higher levels of power. Most conventional units do not have this parallel capability.

Inverter models have integrated parts to make them light and easy to move. Some conventional models are still bulky or overweight.

Finally, with special noise dampening features, the inverter generator is significantly quieter than conventional generators. These benefits make the inverter generator the best choice when purchasing a generator.

Considerations Before Purchasing

When purchasing an inverter generator, you should take six things into consideration.

1. Your power requirement is directly influenced by the fuel capacity of the unit. You should determine the total load requirement before identifying a generator to purchase.
2. Each brand has a different noise level. The amount of noise a generator creates can be a deal breaker. However, when comparing models make sure they are producing the same wattages and are operating at the same load.
3. Consider the control panel of a unit before purchasing it. The best control panels will save you time, energy, and money in the long run.
4. The price of an inverter generator can vary widely among the different models and brands. Price should always be considered when making a major purchase.
5. Depending on your needs weight and portability should also be considered. Typically weight and size will depend on the wattage of the unit.
6. Choosing a model with an economy mode can maximize your savings in fuel.

Pros and Cons of Inverter Generators

As with any type of generator, the inverter generator has some advantages and disadvantages which are:


• An inverter generator has excellent fuel efficiency because of its ability to lower the RPMs when the load is lighter.
• The inverter generator is quieter than most conventional generators.
• The waveform produced by an inverter generator is cleaner which makes it more suitable for sensitive devices such as televisions and computers.
• The smaller and lighter inverter generator is easier to move and carry to different areas.


• The wattage of an inverter generator is limited to typically under 4,000 watts.
• The small gas tanks located on the inverter generator requires you to fill up more frequently than conventional generators.
• Inverter generators can cost more than conventional ones.

Depending on your needs and wants, the advantages may outweigh the disadvantages or vice versa.
