To determine the correct inverter size for your microwave, you must consider the microwave’s power consumption (measured in watts) and the inverter’s efficiency.
Microwave ovens can vary in power consumption, typically 600 watts to 1200 watts or more. Check your microwave’s label or user manual to find its power rating.
The power mentioned on your microwave is the cooking power. For example, a 1,000 watt microwave will use more power than 1,000 watts.
When selecting an inverter, choosing one that can handle at least 1.5 to 2 times the microwave’s wattage is a good practice to account for inefficiencies and potential power surges.
Additionally, consider the inverter’s continuous and peak power ratings. The continuous power rating should equal or exceed the microwave’s wattage, while the peak power rating should be at least 1.5 to 2 times the microwave’s wattage.
Calculation Example
For example, if you have a 1000-watt microwave:
Calculate the minimum recommended inverter size:
1,000W x 1.5 = 1,500W
Choose an inverter with a continuous power rating of at least 1,500 watts.
Choose a peak power rating of:
1,500W x 1.5 = 2,250W
The peak power rating of your inverter should be 2,250 Watts
Match your Microwave to your Inverter
If you already bought your inverter from our list and the power rating is not enough, you can adjust the power of your microwave.
Let’s say your microwave works at 1,000 watts or High setting. For the microwave to work with your 1,000W inverter, you can turn the microwave dial to medium or 500Watts.
You can experiment with this and see at which power rating the inverter trips.
Other Considerations
Remember that the inverter should also be compatible with your power source’s voltage (12V, 24V, or 48V) and provide the correct AC output voltage (110V, 120V, 220V, 230V, or 240V) required by the microwave.
FAQ
Will a 3,000W inverter run a microwave?
We can safely say that a 3,000W inverter will run a microwave. Most microwaves are 1,000 to 1,200W of power. So a 3,000W inverter can run a normal microwave.
Can you run a microwave off a 2,000W inverter?
Yes, a 2,000W inverter can handle a normal microwave. If it cannot handle the power, you need to adjust the microwave power for it to work, as we have described in the article.
