What Is An Inverter Generator?

Inverter generators are used to power everything from campsites to offices, coffee vans and home appliances during blackouts. But what exactly is an inverter generator?

Here we explain what they are, how they work, and the pros and cons.

-

What is an Inverter Generator?

In a nutshell, it is a generator that can safely power sensitive electronic gadgets and smart devices. They produce clean and stable energy in comparison to traditional generators.

-

How Do Inverter Generators Work?

To understand how they work, you first need to understand the inverter. Where traditional generators use a heavy alternator, inverter generators use a lightweight digital electronic alternator - the inverter.

The generator produces DC power, then the inverter "inverts" and converts this to a steady flow of clean AC power. This is what's called stable pure sine wave delivery. It simply means you get power as clean as what you get from the mains power outlets at home!

Pros of an Inverter Generator:

The biggest selling point of an inverter is its ability to produce clean power free from surges ('spikes') that might damage sensitive devices. You can trust the generator to power your favourite equipment on the road.

Another advantage of an inverter generator is the design. The inverter technology allows manufacturers to design ultra-lightweight and compact generators that are perfect for caravanning, 4WD touring and camping. The greater efficiency of inverter generators means they can be up to HALF the size of traditional generators.

Inverter generators also have a greater fuel efficiency compared to traditional models. How? The engine speed automatically adjusts in direct proportion to the load, which means it maximizes the fuel efficiency while maintaining 240V supply. This means you benefit from a longer continuous running time and you don't need to refuel as often.

Finally, inverter generators are much quieter than their traditional counterparts. No loud, vibrating generator units. Inverter generators are typically designed with sound-proofed casing, insulators and mufflers. So, whether you're using it for camping or domestic backup, you don't have to worry about the neighbours.

Cons of an Inverter Generator:

The drawbacks of an inverter generator come down to your power requirements. If you need to power heavy duty machinery and tools, an inverter generator just might not cut it.

Where average sized portable (conventional) generators have models up to around 15,000 watts in size, portable inverter generators max out at around 6000 - 7000 watts making them better suited for smaller power needs, such as camping and caravanning.

You will still see inverter generators on some worksites, but typically they are being used for smaller tools or battery charging. The fact is inverter generators are not designed for heavy, inductive loads. E.g. Running larger, heavy power equipment.
