Inverter generators are a great option when you need a portable, high-quality and reliable source of mobile power.

But with so many brands, sizes and power outputs on offer, it can be hard to know what’s right for your specific requirements.

Here, we’ll break down everything you need to know before purchasing an inverter generator and recommend our top 3 inverter models on offer.

What Is An Inverter Generator?

Inverter generators are a type of portable generator that produces electricity in ‘pure sine wave’ format.

They work by converting AC electrical current into DC, before inverting it back to AC. This creates a clean, consistent wave of electricity safe for powering sensitive electronics like computers, mobile phones and televisions.

The Difference Between A Generator & An Inverter Generator

Inverter generators are smaller, quieter and more energy efficient than traditional generators. They invert the electrical wave, allowing for a consistent, higher quality flow of electricity, similar to that from your power outlets at home.

Inverter generators also automatically adjust their engine speed to meet load demand, meaning greater fuel efficiency for the user.

Non-inverter generators, on the other hand, produce what is called ‘dirty’ power. This is power with a high total harmonic distortion (THD), meaning it is prone to irregularities and voltage spikes that may harm sensitive electronic equipment. Traditional generators can also only run at one speed regardless of the load demand, meaning higher fuel consumption and noise output.

Inverter generators tend to have a slightly higher price point than conventional generators due to their more complex technology. However, they make up for it in their lower operating costs, compact design and high-quality power output.

How To Choose An Inverter Generator

To determine what inverter generator model is right for your specific needs, you’ll want to consider:

Your Power Output

Inverter generators are well-suited to recreational needs like camping and caravanning, as well as backing up small essential items during a blackout. So, if you’re looking to power an entire house or heavy-duty equipment, an inverter generator probably isn’t the right generator for you.

To calculate what size inverter generator you need, create a list of all the items you want to power and for how long. Then, tally up the total running watts of all the items you want to power, and factor in the device with the highest starting watts.

For appliances like fans and phone chargers, starting and running watts will often be the same. For appliances with electric motors, like mini fridges and caravan air conditioning units, the starting wattage can be 3-4x the running watts.

Do You Want To Parallel Two Units Together?

Some inverter generator models, such as the Honda EU22i and EU10i, have the option to parallel two units together to double your power output. This gives you the option to power larger items, like a caravan AC unit without the need to trade in for a larger, less portable generator.

Note: If you want the option to parallel two inverter generators together, ensure you’re purchasing and connecting two identical units.

Is Noise A Concern?

As they’re not running at full speed 100% of the time, inverter generators have a much lower operating volume than traditional generators.

Regardless, if you plan to use your inverter generator in campgrounds or residential areas, you'll need a model with a noise output below 60-65 dBA.

Run Time

If you plan to use your inverter generator frequently, you’ll want to look for a model with a decent run time, preferably above 7-8 hours.

The Genesys GEN2500i for example, has a run time of up to 20 hours, which is 40% longer than other similar size models on the market. 

Our Top 3 Inverter Generator Picks

There’s no shortage of inverter generator models, sizes and brands to choose from. So, to simplify your decision, here’s our top recommendations on the best inverter generators on the market:

1. Most Popular – Honda EU22i

Delivering ‘better than commercial quality’ electricity, the Honda EU22i is perfect for powering phones and laptops on your next caravan or camping trip. It has a maximum output of 2200 watts and can be paired with a second identical model to provide a total power output of 4kVA.

The EU22i is fitted with Honda’s advanced 4 stroke GXR120 engine and built-in Eco Throttle setting, allowing for greater fuel efficiency and a run time of up to 8 hours.

Key features of the Honda EU22i include:

• Run time: 8 hours using Eco Throttle
• Noise level: 53-59 dBA
• Max output: 2400W

2. Best Value For Money – Genesys GEN2500i

The Genesys GEN2500i is an affordable, silent and reliable inverter generator. It produces 2100 watts of continuous stable power, making it the ideal temporary power source for camping and boating trips or for use around the home.

With a large 5L fuel tank, the GEN2500i offers a continuous run time between 6-20 hours. Even better, it weighs only 19.8kg.

Key features of the GEN2500i include:

• Run time: Between 6-20 hours
• Noise level: 52 dBA at 7m
• Max output: 2400W

3. For Large Power Needs – Honda EU70is

The Honda EU70is is Honda’s largest inverter generator on the market. With a maximum power output of 7000 watts, it is well-suited to powering large caravans, food vans, coffee vans and small trade sites.

The EU70is has an advanced electronic fuel injection system that allows the unit to run for up to 18 hours continuously depending on the load. It also comes with an ‘iMonitor’ liquid crystal display feature that provides quick information on the generator’s hours of operation, wattage and engine speed.

Key features of the Honda EU70is:

• Run time: Up to 18 hours using Eco Throttle
• Noise level: 52 dBA
• Max output: 7000W
