What Size Generator To Run Refrigerator And Freezer

Refrigerators and freezers are some of the most common household appliances. It’s important to know what size generator to run refrigerator and freezer, in order to make sure to choose the right size generator for your needs so that your food stays cold during a power outage.

we will discuss what size generator you need to run a refrigerator or freezer. So whether you’re looking to buy a generator for the first time, or are just curious about what size you need for your appliances, let us help you.

What Size Generator Do You Need To Run A Refrigerator And Freezer?

When you’re looking to buy a generator, don’t forget they’re not just for camping anymore. Many people are using them in their homes and business to provide convenience and electricity during power outages. However, when picking your generator size, it’s important to find one that will support the appliances in your home such as the refrigerator and freezer.

So, what size generator do you need to run a refrigerator and freezer? There are a number of variables that go into deciding the right generator for your home. For example, how many appliances will be running at one time and what type of appliances (e.g. dishwasher) will require more power than others? How long do you need to run your appliances? Will you require more than one generator for the larger appliances in the house?

What size generator do I need?

To determine what size generator you will need, here are some things to keep in mind:

Wattage Of Your Refrigerator And Freezer

Most people have a refrigerator and freezer, which use an average of 600 watts each. That means you will need a generator that is at least 1200 watts minimum.

The wattage of your refrigerator and freezer can vary depending on the size and age of the appliances themselves. A newer, larger appliance that runs frequently is going to draw more power than an older model that doesn’t run as frequently. They also use energy differently: a refrigerator’s compressor runs constantly, while a freezer only uses energy once the door is opened.

Your generator should have enough power to support your refrigerator and freezer plus other appliances at the same time without tripping an overload circuit breaker. Overloading your generator can damage it or lead to catastrophic failure. If you are using more than one generator, they should both be the same size so you don’t overload them.

How To Calculate Wattage Requirements

As a practical example, here is how to calculate your minimum wattage requirements:

  • A standard fridge uses about 600 watts on average. So for one hour of run time, it will use 600 watts x 1h = 600 Wh (watt-hours). A freezer that runs for 10 hours will use 600 Wh x 10h = 6000 Wh (watt-hours). If you’re running both the fridge and the freezer, then it would be 6000 Wh + 600 Wh = 6600 Wh (watt-hours). The minimum power that your generator should be able to run is 6.6 kWh (kilowatt-hour) minimum.
  • Another practical example: If you have appliances that use a total of 8 kWh over a 24-hour period for cooking, heating, and other needs, it could be a refrigerator and a chest freezer or one large upright freezer. A generator sized at 8 kWh would allow the appliance to run up to half that time without adding another generator to the load.

Suitable Size Generator To Run Refrigerator And Freezer

  • A 10 kW generator would be suitable for most homes that run a refrigerator and freezer plus other appliances at the same time without tripping an overload circuit breaker. If you’re running multiple generators, they should all be the same size so you don’t overload them. Be sure to calculate your wattage requirements before purchasing a generator.
  • Another option is a portable inverter generator. A 12,000-watt inverter generator can be used to power appliances that have motors or heating elements such as a refrigerator, furnace, stove, and more. The benefit of an inverter over a standard generator is that it regulates the voltage to a constant 120 Volts AC. Inverter generators are ideal for starting sensitive equipment, such as computers and TVs.

However, if you need to power a large oven or commercial refrigerator in your restaurant or business that requires heavy-duty 240 volts of power, then you will want a generator with a transfer switch. This will allow the appliance to run off of 208 Volts AC while powering a 240 VAC appliance with a dedicated circuit. A generator that can power a commercial refrigerator this size would be much larger, from 25 kW-75 kW minimum.

The right size generator will support your power needs when you need it most without overloading or causing damage to the generator. Different generators are available for household and commercial use, ranging in power from a few kilowatts to hundreds of kilowatts.

Some generators can even be connected to solar panels to be independent of the electrical grid. Be sure to calculate your wattage requirements before purchasing a generator.

FAQs

What Size Generator Will Run My Refrigerator?

Your refrigerator needs 6.6 kWh (kilowatt-hour) to run for 24 hours while a freezer only uses up to 3.3 kWh for 24 hours. Be sure to calculate your wattage requirements before purchasing a generator.

What Size Generator Will Run My Refrigerator And Freezer At The Same Time?

A standard fridge uses about 600 watts on average. So for one hour of run time, it will use 600 watts x 1h = 600 Wh (watt-hours). A freezer that runs for 10 hours will use
600 Wh x 10h = 6000 Wh (watt-hours). If you’re running both the fridge and the freezer, then it would be 6000 Wh + 600 Wh = 6600 Wh (watt-hours). The minimum power that your generator should be able to run is 6.6 kWh (kilowatt-hour) minimum.
Another option is a portable inverter generator that will provide constant voltage to sensitive equipment such as computers.

What Size Generator Will Run My Commercial Refrigerator?

If you need to power a large oven or commercial refrigerator in your restaurant or business that requires heavy-duty 240 volts of power, then you will want a generator with a transfer switch. This will allow the appliance to run off of 208 Volts AC while powering a 240 VAC appliance with a dedicated circuit. A generator that can power a commercial refrigerator this size would be much larger, from 25 kW-75 kW minimum.

What Size Generator Will Run My Whole House?

A generator that can power a home requires between 25 kW and 75 kW. Inverter generators are more energy-efficient and easier on the generator itself, making them a good choice for powering sensitive appliances such as computers.

Conclusion

Be sure to calculate your wattage requirements before purchasing a generator. If you’re unsure what size generator to run the refrigerator and freezer is best, ask the experts of Generator who will help you choose the right generator for your needs.
