# What Size Power Inverter do I Need for a 700 Watt Microwave?

It is crucial to determine the appropriate size of a power inverter for your 700-watt microwave before making a purchase. A properly sized power inverter ensures the smooth operation of your microwave without risking damage to the equipment or safety concerns. In this article, we will answer the question, "What size power inverter do I need for a 700-watt microwave?" and provide relevant advice and recommendations.

## Determine the rated power of the microwave

Firstly, you need to check the specifications or product manual of your microwave to find its rated power. In this case, we know that the microwave has a rated power of 700 watts.

## Consider the efficiency of the inverter

The efficiency of an inverter refers to its ability to convert DC power to AC power. Generally, the efficiency of inverters ranges from 80% to 90%. Therefore, to meet the requirements of a 700-watt microwave, you need to select an inverter with sufficient output power.

## Calculate the required inverter power

To ensure that the inverter can meet the needs of the microwave, we need to calculate the required inverter power. The formula for calculating inverter power is as follows:

Required inverter power = Microwave rated power / Inverter efficiency

In this case, assuming an inverter efficiency of 90%, the required inverter power is:

Required inverter power = 700 watts / 0.9 ≈ 778 watts

Therefore, it is recommended to choose a 1000W inverter or higher power product when choosing.

In addition to the rated power of the microwave, you should also consider the power requirements of other devices. If you plan to use other devices simultaneously with the microwave, such as a coffee maker or induction cooker, you may need to choose a higher power inverter to meet the needs of all devices.

Choosing the right power inverter for a 700-watt microwave requires considering the microwave's rated power, the efficiency of the inverter, and the power requirements of other devices. Based on the calculation, you need to select an inverter with an output power of at least 1000 watts. If you plan to use other devices simultaneously, choose a higher power inverter.
