Will A 1500 Watt Inverter Run A Refrigerator?

If you want to buy a 1500 watt inverter for residential use, then a common question may arrive in your mind first – will a 1500 watt inverter run a refrigerator?

However, you will have several other power inverters on the market. A 1500 watt power inverter is one of the most common and popular inverters.

A 1000 watt power inverter has a capacity of a 2000 surge watt peak. In fact, you will get enough power to operate your refrigerator. A 14 cubic foot refrigerator consumes 1000 watts per day. However, it also needs 2000 watts of surge power to begin.

What Are the Types of 1500 Watt Inverter

There are several categories of inverters. Here is a list of major inverter categories that you can consider.

  • Input Voltage (12V, 24V, 36V, 48V): 

 If you use a battery bank, then the input voltage of your inverter should match the nominal battery voltage. After that, you can choose the AC output voltage.

  • Output Voltage (110/120V or 220/240V): 

 It is important to know the output voltage of your inverter. Because if the output voltage doesn’t match with the appliances, it will not work profoundly. 

  • Waveform: 

There are two main types of waveforms: Pure Sine Wave and Modified Sine Wave. Pure Sine Wave inverters are expensive and Modified Sine Wave is most of the time used for tools and other basic appliances.

  • Design:

A High-Frequency sine wave is often used for many small appliances. Low-Frequency Pure sine waves offer many features.

Which is Better – Pure Sine Or Modified Sine Wave Inverters?

Pure sine wave inverters – can create quieter, smoother, and more reliable electricity to run appliances without having any interference. 

Benefits of Pure Sine Wave Inverters:

  • Decreases electrical noises in television, fax, fans, etc. 
  • Also prevents crashes.

Modified sine wave inverters – are a cost-effective choice to operate appliances. 

Benefits of Modified Sine Wave Inverters:

  • Lower in cost than a pure sine wave inverter.
  • Money-saver
  • Best choice for the devices that operate on non-sinusoidal current.

Pure sine wave inverters are a spendier choice for many consumers. However, as the price of pure sine wave inverters is dropping, they become more affordable and popular.

Pure sine wave inverters are more efficient compared to modified sine wave inverters. In some cases, modified sine wave inverters are enough. However, a pure sine wave inverter is an optimum option for a typical refrigerator.

As a refrigerator needs a lot of power, it is important to have a high energy-efficient inverter. From a pure sine wave inverter, you can get 30% more watts compared to a  modified sine wave inverter.

Both pure sine wave inverter and modified sine wave inverter are capable of 1000 running watts and 2000 surge watts. However, a pure sine wave inverter is 95% efficient. On the other hand, a modified sine wave inverter is 80% efficient.

What Can a 1500W Inverter Run?

A 1500 watt inverter can operate devices with running power consumption that is fewer than 1500 watts. But there are several factors that you need to bear in mind. Total power consumption should never exceed 1500, if it exceeds then you should turn off your device immediately.

Will A 1500 Watt Inverter Run A Refrigerator?

A power inverter can become your life savior during camping, residential uses, or long road journeys. A 1500 watt power inverter can convert DC power to AC power. So, you can effortlessly charge and operate a wide variant of your electronic equipment or appliances, including refrigerators, smartphones, laptops, etc.

An emergency backup will always save you from a nightmare environment. A 1500 watt inverter has a wide range of applications. A 1500 watt inverter is enough to run a refrigerator. But if you want to know how long an inverter can run a refrigerator? Generally, it depends on the power consumption of your fridge and the available power to the inverter. For a larger fridge, you will need more batteries. 

Useful Tips For Running A Refrigerator On An Inverter

If you want to operate a refrigerator on an inverter, then you can apply the following tips to get the highest performance and reduce costs.

  • Try to purchase an energy-efficient fridge. Take your time to analyze and compare different models until you find the most energy-efficient one.
  • Consider buying the best quality inverter. You can also compare different models just like the fridge.
  • Never operate your inverter at its highest capacity.
  • You should calculate the power usage, not only for your refrigerator but also it is important for any device that you want to operate on the inverter.

How to Choose the Appropriate Inverter?

Here are some tips to choose the correct inverter that you can consider while purchasing a new inverter.

  • Rating

Do some proper planning before buying the inverter. You need to determine the actual watts you require.

  • Noise

All the inverters use fans. So, you can go through the reviews to check whether it produces noise or not.

Final Words

Refrigerators have become more energy-efficient nowadays. However, refrigerators are one of the biggest energy users. The most important key to operating a refrigerator on a 1500 watt inverter is to have enough running and surge-watt capacity. And if you need to run your refrigerator with other devices or appliances, then you should have a bigger inverter and battery bank.
