Best Inverter Generators in 2019 Reviews and Guide

Last Updated September 5, 2019

Too much noise and high fuel consumption are two factors that prevent people from owning a standard generator. But imagine if that was not the case.

But that’s not all.

If you buy a conventional generator, how would you charge your sensitive electronic devices with that?

That’s where the inverter generators come and we have listed the best inverter generators in the market.

But before I share with you the inverter generators reviews we have tested and done research on, it’s crucial you have a deep understanding of why we recommend these generators in the first place.

Most importantly, why they are better than the standard generators. An excellent way to kick off this conversation is with the definition of what

What Is An Inverter Generator?

Inverter and generator are two words which mean different things to different people. A lot of people that buy it gets confused about what it is in the first place.

Let’s define the word inverter?

A typical inverter will receive power from a static direct current source. Most inverters are present in cars or solar panel.

Once the Direct Current (DC) is received, it is reversed to Alternating Current (AC). Power in the form of AC can be used when needed.

Most gadgets at home use AC power, and that’s why it is an excellent choice for you to have an Inverter Generator.

Let explain an inverter generator:

An inverter generator is a recent innovation from the standard generator. It uses advanced electric circuitry and magnets. Power conversion in an inverter generator happens in 3 stages:

  • Output for AC
  • AC converted to DC
  • DC ‘inverted’ to clean AC

What Benefit Comes From Using an Inverter Generator

Quality power output- an inverter generator is reliable and efficient. In other words, power is closer to the line.

Light and portable- Designing a generator require advanced technology. It usually entails putting the size into consideration without compromising the efficiency. The good news is an inverter technology combines the engine parts and the generator so that it is small.

Most inverter generators weigh around 30 to 50 pounds. They are easy to carry and store. You can fit them into the car.

Fuel efficiency– an Inverter generator uses advanced technology that adjusts engine acceleration to emit power when it’s needed. That way, you save on fuel.

Most traditional generators run at a high RPM but inverter generators run at lower RPM and maintain the frequency without stopping.

But here’s the most exciting part.

They don’t have a large fuel tank, but that doesn’t mean they run out of fuel. Their engine is fuel-efficient. It can adjust the engine speed depending on the application.

Low-noise– Traditional generators produces lots of noise that you can’t even focus on your conversation.

On the flip side, an inverter generator produces less noise. Most of the inverter’s engine never run at full speed but provides more power.

Conventional generator always operates at 75 decibels, which is the same noise like that of a jet engine.

Inverter generator makes less noise. Best of all, they do have unique stationary material such as the cooler engine, muffler, and noise dampening technology.

Great price- All these advantages, it is so easy to think that the cost of an inverter generator is high. If you want to experience the benefits, think of how much you will save fuel in the long run.

In a scenario where data is lost due to power changes, an inverter generator will ensure the safety and function of that hardware.

Will Inverter Generator Cause Harmonic Distortion

Harmonic distortion is a problem common in so many standard generators.

The good news is, it is not present in an inverter generator.  The rate of Harmonic Distortion is low.

Let me explain in detail:

HD makes electric motors less effective and overheat. HD mostly affects home electrical equipment that uses microprocessors.

Devices that use microprocessor at home include Television, smartphones, computers, tablets, microwave and many more.

The devices suffer from excess heat, which affects how they function. And if these devices are exposed continuously to Harmonic Distortion, it may damage the circuitry system leading to failure of the equipment.

A Portable Inverter generator uses Insulated Gata Bipolar Transistor (IGBT) technology. The technology creates a near-perfect sine wave that is superior to MOSFET because it creates lots of power.

The Pulse width modular controls those sine waves to limit Harmonic Distortion in an inverter generator.

It works to ensure there’s a clear path sine wave, that can be used even with the sophisticated electrical gadgets.

Do Inverter Generator Offer Parallel Connection

Most portable inverter generators operate at a 2000 to 3000 wattage range. It is a lot of power if you have large appliances.

With the parallel connection, you can connect two inverter generators to boost the power output. The best way to make it work is to ensure both have the same wattage and you bought them from the same manufacturer.

How Big Should My Portable Inverter Generator Be?

The term “Big” refers to a power supply and output in watts. The first thing is not determining the size; the first thing is running the math.

You need to know the total wattage of all the devices you will use in the event of power outages.  You will notice that some appliances like microwaves or charcoal starter may need lots of power for them to run.

Once you have the total wattage, you confidently know what kind of portable inverter generator you need to buy. But if you want the whole house to use power, then a portable inverter generator is not for you.

The good news is, most portable inverter generators have a power output ranging from 1,400w to 4,000w of production.

Chances are, if you only need to ensure essential devices run in the event of power outages, your wattage calculation will be in that range.

You can also go high up in case your wattage is high up.

How Many Outlets Should an Inverter Generator Have?

The question is, how do you want to use an inverter generator?

The number of outlets will determine if you can use other devices or not. If you want all your tools to use a portable inverter generator at the same, you need to make sure you have the right number of outlets.

Here are three questions you need to ask yourself:

  • How many electronics do you have?
  • How often will you use these electronics?
  • How many do you use?

Most portable inverter generator will come with different outlets. For example, if you are a person who loves to use one or two plugs, there’s no need for many outlets.

FAQs For Portable Inverter Generators

What’s Efficiency Mode?

The inverter has an Eco mode that is useful if you want to increase efficiency or decrease noise. All you need is to switch it on.

In other words, they work with the generator to reduce fuel consumption and make it run low. A lot of sophisticated technology goes behind it.

Depending on the kind of portable inverter generator you will use, the most prominent function of the Eco-mode is to detect a lower power and make the generator run slow so that you can save more gas.

What is Overload Protection?

It is a smart circuitry feature that detects when the generator is overdrawn and shuts down, blow a fuse or disrupt the circuit. This is the exact opposite for surge protector.

Is there anything I can do if my fuse blows?

If a fuse of a portable inverter generator blows, it means there’s something wrong with the circuity. At this moment, you don’t need to reset the fuse but turn it on.

A fuse blowing up means there’s a problem, and you need to solve it when you turn it on so that you can know the root cause.

Sometimes the problem is loose connections or frayed wires. All these can cause the fuse to blow.
