Inverter generators and how they work

If you need quiet and clean energy, you should consider buying an inverter generator.

An inverter generator is a great choice for powering your camping site, RV, sporting event, mobile restaurants, and other facilities.  This is because the generator is quiet, portable, and produces high-quality power.

What is an inverter generator?

In an inverter generator, the engine is electronically throttled up and down according to the power demand, unlike the traditional generators that run full tilt always. This increases the efficiency of the generator and means you don’t have to fill the gas tank as often. This also makes inverter generators to be quiet and to produce a low emission.

How does an inverter generator work?

Both the traditional generator and an inverter generator work in a similar way. They both start by producing standard power. The alternator of the generator produces a raw, high voltage multiphase AC power. But this is where the similarities end. Once the AC power is produced, the inverter generator uses a microprocessor to change the power into the Direct current. The Direct Current (DC) is then converted by the inverter generator into AC power.


Types of inverter generators

Inverter generators can be categorized into two: The open-frame and the closed frame. Open frame generators don’t come with any form of insulation and are usually louder as compared to the closed frame generators. However, they are still quieter as compared to the traditional generators. The open frame generators produce clean power just like the closed frame inverter generators. They can also handle some larger loads.

Closed frame generators come with a protective shell that has noise-absorbing insulation. This helps them to reduce the acoustic impact. These generators are often portable and are a good choice for powering small loads. Whether you choose an open-frame or a closed frame inverter generator will depend on the devices you are powering, your power needs, acceptable noise levels, and much more.

Benefits of inverter generators


The sound of a generator running isn’t very pleasing. Sadly, the majority of open-frame generators have a noise level above 65 dB. This means that they aren’t the best choice for recreational purposes.

One of the benefits of inverter generators is that they are quieter. The majority of inverter generators have a noise level of 50 to 60 DB depending on the load. Some of the best inverter generators produce as little as 49 dB when at a quarter load. This is quieter than a conversation between two people.

Bigger inverter generators that produce 3000 to 4000 watts are a bit louder.  However, with a bit of research, you can find a good inverter generator that produces about 65 dB. Such a generator can be a good choice for powering your campsite or RV.

Safe for sensitive electronics

Inverter generators are some of the best choices for clean energy.  The Total Harmonic Distortion is a metric that measures how clean a source of energy is. If a generator has a THD of above 6%, it can destroy sensitive equipment such as mobile phones, laptops, and home theater systems.

The majority of the older portable generators have a THD of more than 10% and this makes them unsuitable for the above electronic equipment. On the other hand, small and big inverter generators have THD of less than 5%. This makes them a good choice for people who need a portable generator for powering their expensive equipment.

Inverter generators and how they work


When you compare an inverter generator producing 2,000 watts to an open-frame generator with the same wattage, you will notice that the inverter generator is smaller and can be easily moved around. These make the machines to be a good choice for camping trips and outdoor events.

A 2000-watts generator is small and lightweight and you can easily lift it. Even when it comes to the bigger inverter generators, they are less cumbersome to transport as compared to the conventional units.


As compared to the open-frame generators, inverter generators use less fuel. This is because the models have an idle control that is referred to as economy mode or eco-throttle. The model you choose will have the idle control feature, either inbuilt on as something that can be turned on and off from a control panel.

The idle control of an inverter generator enables you to adjust the speed and ensure that it only burns fuel that can power your equipment. While the typical standby generator runs at a constant of 3600 RPM and provides users with 60 Hz of power, an inverter generator is made to provide 60 HZ at a varying RPM. This means that if the RPM is lower, you will enjoy a fuel efficiency of 20 to 40%. This will also result in lower emissions.

Drawbacks of inverter generators

While inverter generators are great, they also come with a downside. These include:


This is the most obvious drawback of inverter generators. These units tend to be expensive as compared to the traditional units. This is particularly the case for the units with higher wattage that costs more than the typical portable generators. Fortunately, with technological advancement, we are seeing every day, inverter generator prices are decreasing every day.

Lower power output

Another disadvantage of buying an inverter generator over a conventional generator is the output. Since inverter generators are smaller, they aren’t as powerful as their bigger counterparts. While a small inverter generator will power your small appliances, if you need to run some bigger appliances, these small inverter generators may not have plenty of power. The good news is that you can run the generators in parallel mode.


There is no doubt that inverter generators have many benefits that makes them be great units for running your RV or campsite. If you need a quiet generator that produces clean energy, an inverter generator is a way to g.
