Microwave ovens tend to be a staple in all kitchens. When it comes to choosing one, though, things can get challenging.
A quick look on the market shows you that there are normal microwave ovens and inverter microwave ovens. The latter claim to have superior performance, but is this true, or is it only a marketing hoax?
I’ve put many inverter and non-inverter microwaves to test to find it out. This guide will tell you why an inverter microwave oven is the best choice and which is the best microwave with inverter technology you can find.
What is an Inverter Microwave Oven?
An inverter microwave oven is a microwave oven equipped with inverter technology. This technology allows the oven’s magnetron (the component generating the microwaves) to run continuously while only alternating the amount of radiation based on the cooking temperature required for your selected setting.
The constant power level not only improves cooking performance but also prolongs the oven’s lifespan.
Another advantage is the minimal current fluctuation on the circuit. Because the oven uses constant power from the start to the finish of a cooking cycle, any changes in temperature won’t require additional surge power.
While this may not seem important at first, you’ll notice the difference if you want to plug in another appliance on the same circuit while your microwave is in use.
Why is it important to have inverter technology in a microwave oven?
Having inverter technology in a microwave is important for several reasons. In a nutshell, though, the inverter technology enables more precise temperature control and avoids the formation of hot spots. Thanks to even cooking, you won’t end up with partially thawed foods or overcooked areas.
Inverter microwave advantages and disadvantages
Advantages
Even cooking: Because the inverter technology enables the magnetron to run continuously, it prevents hot spots and cooks food evenly. Defrosting is also faster and even, so you won’t have to worry about your food remaining partially frozen.
Faster cooking times: Not only will an inverter microwave oven cook better, but it will also cook faster. In most cases, you can do more with less power.
Energy efficiency: Faster cooking times mean more than having your meal ready quicker; they also mean your oven needs less energy to cook your meal, which means lower electricity bills.
Disadvantages
Price: Inverter microwaves are generally more expensive than conventional microwave ovens.
Regular microwave vs. inverter microwave: What’s the difference?
I mentioned that inverter microwaves are more efficient than conventional ones and conventional ones are cheaper, but what exactly is the difference between the two?
It all comes down to the way the magnetron works.
In a conventional microwave, the magnetron always works at full power. In other words, if your microwave outputs 1,000 watts, the magnetron will always output 1,000 watts. To adjust the power to your selected setting, the motherboard will turn the magnetron on and off at set intervals.
However, the microwave’s turntable doesn’t stop when the magnetron stops. Because of this, the oven might not be able to heat the food evenly.
This creates problems in both cooking and defrosting; your meals may find overcooked and undercooked pieces of food in the same dish, or your frozen meal may come out only partially thawed.
Using another appliance on the same circuit when your oven is in use may also be impossible because the magnetron determines a surge in power each time it turns on.
In an inverter microwave, the magnetron is capable of adjusting the power level to match the selected setting. The component doesn’t turn on and off throughout the cooking cycle, ensuring even cooking with no hot spots.
Because the magnetron doesn’t switch on and off constantly, you may be able to use another appliance on the same circuit even when your microwave oven is in use (provided the circuit has sufficient amperage). The oven’s lifespan is also longer.
How to choose an Inverter Microwave?
Power/Wattage
What do you plan to do with your microwave oven? Do you need it for fast heating and defrosting only? About 800-950 watts may suffice.
Do you want to cook elaborate meals or look for a smart inverter microwave oven that can also bake and roast? Look for power of at least 1,000 watts.
Design
Where do you want to place your oven? If counter space is not an issue, opt for a countertop model. An over-the-range unit can help you save counter space. You could also opt for a built-in microwave oven or a microwave drawer if you want to give your kitchen a streamlined design.
Capacity
Consider the size of your family when choosing. A small capacity below one cubic foot is perfect for one or two persons. If your household has more than three members, choose a unit that has at least one cubic foot of capacity.
Turntable
Another thing you may want to decide is whether or not you want a turntable. If you decide against a flatbed microwave, consider one with a turntable off function that would allow you to use it with rectangular trays or pans. Otherwise, you’ll only be able to use your oven with smaller-size trays.
Brand
The brand is almost always a guarantee of quality. Among the best inverter microwave brands, I can mention Panasonic, Toshiba, LG, and Galanz.
Cooking time, sensor, and Technology
Pre-programmed cooking settings and sensor cooking technology can take the guesswork out of the game. Most microwaves nowadays have these settings, so you’re spoilt with choices if you need these functions.
Buttons
Is the control panel intuitive and easy to use? Are the buttons easy to operate and clean? These are a few other things to control before buying.
