What is an Inverter Generator

An Inverter generator is used to power everything from campsites to offices, coffee vans and home appliances during blackouts and power outages. It is a generator that can safely power sensitive electronic gadgets and smart devices.

How Do Inverter Generators Work?

Traditional generators use a heavy alternator, whereas inverter generators use a lightweight digital electronic alternator, this is the inverter.

The generator produces DC power, then the inverter “inverts” and converts this to AC power. This can also be called stable pure sine wave delivery. It simply means you get power as stable as what you get from the mains power outlets at home.

Pros of an Inverter Generator:

The biggest selling point of an inverter generator is its ability to produce power free from surges (‘spikes’) that might damage sensitive electronic devices.

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 off-grid and portable situations. The greater efficiency of inverter generators means they can be up to half the size of traditional generators.

Inverter generators also have greater fuel efficiency compared to traditional generators. 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.

Inverter Generators are also 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 have the grunt to do 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.
