The Best Inverter Microwave: Our Picks

Buying and Evaluation Criteria for Inverter Microwaves

When you search the internet for the perfect microwave for you, you will come across many different models from various suppliers. In this section, we will show you which criteria you can use to compare inverter microwaves.

In summary, these are:

In the following, we will now go into more detail on the individual purchase and evaluation criteria.

Capacity

Microwave ovens with inverter technology have a capacity of between 20 and 27 litres. The size of the cooking chamber varies depending on the size of the microwave and the presence of a turntable.

Appliances with a capacity of 27 litres can easily accommodate the majority of frozen pizzas. Large food plates are also no problem. Combi ovens with a hot-air function, for example, are also among the larger models.

If you are in a single household or you only want to heat smaller portions, appliances with less cooking space are also perfectly adequate.

Inverter technology can save a lot of space in the appliance. Many suppliers offer up to 20 % more cooking space with the same external dimensions compared to conventional microwaves.

Performance

For comparison: Conventional microwaves are usually offered with power ratings between 700 - 1000 watts.

Similar to conventional microwaves, the power of inverter microwaves ranges between 800 and 1000 watts. Occasionally, there are also devices with up to 2000 watts on the market. However, these are mainly found in the catering industry.

However, a higher wattage does not necessarily mean a better appliance. Depending on the food to be heated, different wattages are required. In most cases, however, the range used is below 800 watts. 1000 watts are required for special microwave functions, for example.

In the table below you will find a small guide to how many watts are needed for what:

Power Use
90 watts defrosting delicate foods such as butter
300-600 Watt heat pre-cooked foods
700 Watt Boil 1 cup of milk
1000 Watt Grill function, hot air function

The time you set depends on your appliance and how hot you want your food. If the food is not hot enough after the set time, put it back in the appliance for a few minutes. Do not increase the power!

Built-in / freestanding

Inverter microwaves are available as built-in or freestanding appliances. Depending on whether you want to fit your appliance into a kitchen cabinet or place it on the worktop, this is a decisive criterion for your purchase.

If you want to build the appliance in, you should pay attention to the dimensions of your microwave. Otherwise, it might be too big for the space you plan to have in the kitchen cabinet.

The door opening of the microwave should also be considered. Some appliances open with the door hinged at the bottom, similar to an oven. Others open with the door on the side. If you want a built-in microwave, you should choose the space so that you can open the appliance easily.

The biggest difference between built-in and freestanding microwaves is the design. With the freestanding version, there must usually be a certain amount of free space between the appliance and the kitchen cabinets, for example.

With / without turntable

As with conventional appliances, inverter microwaves are available with or without a turntable. The main task of the turntable is to distribute the heat evenly by rotating the food.

During your research, you will mostly come across inverter microwaves without a turntable. Since the temperature does not fluctuate with this technology, but is used in a targeted manner, a turntable is often not used.

If there is no turntable, the cooking area of the microwave is larger. Likewise, cleaning the appliance is made easier, as only one large area needs to be cleaned.

In some appliances with a turntable, it is possible to remove it and heat food without it. Some larger microwaves also come with a small baking tray that can be used instead of the turntable.

Guide: Questions you should ask yourself before buying an Inverter Microwave

If you want to buy an inverter microwave, you should consider a few factors. In the guide you will find the most important questions with short answers. After reading this section, you will know the most important key points.

What is special about an inverter microwave and what advantages does it offer?

A commercial microwave without inverter technology uses electromagnetic waves to heat food. The appliance heats up and switches off again at intervals.

In contrast, the inverter microwave has an electronically controlled power supply, which keeps the selected heat constant. Depending on the food, the temperature of these appliances can be set precisely.

  • Constant temperature: The inverter microwave heats food in a time-saving way and also saves energy by keeping the temperature constant.
  • Full flavour: You can adjust the temperature exactly to the food you want to heat, so no flavour is lost.
  • No loss of nutrients: Due to the even heating, the dishes are reheated as gently as possible to retain nutrients.
  • Fully heated: The inverter technology also prevents your porridge, for example, from being hot on the outside and still cold on the inside.

What types of inverter microwaves are there?

There are also different types of inverter microwaves, which we will introduce to you in this section with their advantages and disadvantages. In the following, we will focus on the three main categories:

Inverter microwave with grill function

One type of inverter microwave is one with a grill function. With the help of these microwaves, you can bake meat, breaded foods or even pizza until crispy.

Even over-baking is no problem with these appliances, as a browning effect takes place. They are therefore a real alternative to the oven when it comes to refining individual portions.

Advantages
  • Browning effect
  • Crispy baking possible
  • Alternative to the oven saves energy
Disadvantages
  • More expensive than appliances without additional functions
  • relatively small size

Inverter microwave with hot air

Inverter microwaves with hot air are also a substitute for ovens, which in turn saves money. With the hot air function, you can even bake smaller cakes in your microwave. Here, the inverter microwave offers the advantage over conventional appliances that the temperature remains constant during baking. So nothing stands in the way of a successful bake!

This function is now included in many appliances and often makes little difference to the price. Just like the grill function, you can also use hot air to bake pizzas.

Advantages
  • Substitute for oven
  • temperature remains constant
  • crispy baking possible
Disadvantages
  • Saves energy compared to oven
  • relatively small size

Inverter microwave with steamer

The third type of product is an inverter microwave with a steam cooking function. The steam cooking function is good for fish and vegetables, for example, so that nutrients are not lost during cooking.

Compared to conventional steam cookers, however, microwaves with this additional function have a relatively small cooking chamber. Depending on the appliance, sometimes only a third of the capacity of a large steamer.

However, if you only want to prepare dishes for 1 - 2 people in your combi oven, you can save a lot of energy. These appliances come with small cooking trays on which you can spread your food. You can often place several trays on top of each other in your microwave.

Advantages
  • Space-saving alternative to a steamer
  • gentle cooking of food
  • cheaper to buy than a steamer
Disadvantages
  • Small cooking space
  • expensive additional function

In addition to the product types presented here, there are also combination variants in which a microwave offers several functions. For example, an appliance that offers both a grill and a hot-air function.

Who are inverter microwaves suitable for?

Do you want a quick hot breakfast, lunch or dinner and still want good taste? Or do you maintain a healthy and balanced lifestyle and attach great importance to nutrient-rich dishes? Then an inverter microwave is exactly what you need!

Thanks to the innovative technology, you can even save energy and money. Depending on the model, this version of the microwave is also a good option for student flats or smaller families to leave the oven behind and prepare smaller dishes in the inverter microwave.

What does an inverter microwave cost?

The cost of an inverter microwave varies depending on the brand and functions. The price range is approximately €150 to €500. The more additional functions your inverter microwave has, the more expensive it will be, hence the wide range.

Inverter microwaves from 150 € are smaller models with a maximum of one additional function. From €250, you can expect larger combination appliances. For example, microwaves with a grill or an oven combination. If you only want to heat your food gently, microwaves in this price range are perfectly adequate.

At the upper end of the price range are large inverter microwaves, which are mostly used in the catering industry. At a price of 500 €, these appliances not only have an additional function, but offer several of the functions presented above combined in one appliance.

How big are inverter microwaves as a rule?

Inverter microwaves are available in different sizes. This depends on how much capacity they have and whether it is a built-in or freestanding appliance.

In most cases, inverter appliances are smaller than conventional appliances, as the built-in magneton for the inverter technology requires less space. This means that some models even have more cooking space with the same external dimensions.

How do I clean an inverter microwave?

Like conventional models, you should clean your inverter microwave regularly to remove odours and dirt from the appliance. You can follow the same principle as for standard microwaves.

Variant Here's how
Water and citric acid In this method, you fill a small bowl with water and place lemon slices in it. Leave the bowl in your microwave for 5 minutes at a high temperature. After the 5 minutes, you can easily remove dirt with a damp cloth. At the same time, bad smells are removed and your microwave smells of fruity lemon.
Dishwashing liquid For more stubborn grease stains, you can use dishwashing liquid. Mix a solution of warm water and washing-up liquid. Then dampen your cloth with it and wipe the microwave with it. This should make your appliance sparkling clean again. Dishwashing detergent also helps with burnt-in spots. To do this, place a cloth that you have previously soaked in the detergent solution in your appliance and switch it on for a few minutes. This produces steam, which makes it easier to clean the spots.

For appliances with a steam cooking function, make sure to clean the water tank regularly and always use fresh water.

Some appliances have a special cleaning programme that you can use to easily remove dirt.

Can I bake a crispy pizza with an inverter microwave?

To make a frozen pizza crispy with an inverter microwave, you should use an appliance with a grill function. These manage to create a browning process and provide toasted aromas.

Depending on the appliance, it may be necessary to heat up the pizza first with a defrost programme and then use the grill function to bake it until crispy. Some microwaves come directly with a special pizza function that does just that.

A little tip from the editors: If you have an inverter microwave with hot air, it works just as well!
