Some of the most popular appliances in homes are refrigerators and freezers. Knowing what size generator to run refrigerator and freezer can help you pick the best generator for your needs and ensure that your food remains cool during a power outage.
We’ll talk about the size of the generator required wattage to power a freezer or refrigerator. We can thus assist you whether you’re seeking to purchase a generator for the first time or are just unsure what size you want for your equipment.
Factors To Consider When Choosing A Generator Size To Run A Refrigerator And Freezer
Factors to consider when selecting a generator size to operate a refrigerator and freezer:
The power needs of the refrigerator and freezer
The amount of generator required is mostly determined by the power needs of your refrigerator and freezer. On the website of the manufacturer or in the user guide, you can often find information about these appliances’ power consumption.
Wattage Of The Refrigerator And Freezer
When choosing a generator to power a refrigerator or freezer, wattage is a crucial consideration. To find out the precise wattage, it’s crucial to review the specifications of the particular brand of freezer and refrigerator you want to use. It’s also worth noting that power needs vary depending on whether the appliance is in cooling or defrost mode, as well as the age and condition of the device.
Voltage And Amperage Requirements
Another crucial consideration when choosing a generator is the voltage and amperage needs of a refrigerator or freezer. The normal voltage needed for a basic domestic refrigerator or freezer is 120V. The amperage requirement may be found in the specifications of the appliance and is measured in amperes (A) or amps. Depending on the size and kind of device, a refrigerator or freezer may need a different amount of amperage. Make sure the generator you choose can provide the appropriate voltage and amperage to power your freezer or refrigerator. Inadequate voltage or amperage might result in poor performance or even damage to the device.
The duration of usage for the generator is
The size required will also depend on how long the generator will be in operation. A generator that will be in use for a brief time won’t need as much power as one that will be used for a long time.
The place and environment in which the generator will be used:
The size of the generator required might also be influenced by the environment and area where it will be deployed. For instance, a generator used in a cold region will need more energy to run than one used in a warm one.
The Availability Of Fuel For The Generator
Another crucial factor is the availability of fuel for the generator. In a location where fuel is hard to come by or is rare, a generator that uses a lot of fuel may not be viable.
The Backup Time
The size of the generator you require also depends on how long of a power outage you are anticipating. The appliances will need to be kept running on a bigger generator if the projected duration of the power outage is longer.
The Starting And Running Wattage
The starting and running wattage of the generator is also vital to consider. The refrigerator and freezer will need beginning watts to start the compressor, and operating wattage to keep it running. The generator must be able to produce both the starting and operating power for the appliances.
Other Loads That Need to Be Powered Include
In addition to the refrigerator and freezer, the generator will also need to power lighting and other appliances. When choosing the generator size, certain loads should be considered.
What Size Generator Do You Need To Run A Refrigerator And Freezer?
To determine what size generator you will need, here are some things to keep in mind:
Wattage Of Your Refrigerator And Freezer
You must calculate the total wattage and amperage demands for all appliances and gadgets that will be operating simultaneously to establish the size of the generator required to operate a refrigerator and freezer.
The Starting And Running Wattage
Check the model’s specs to first ascertain the starting and running wattage of the refrigerator and freezer. The amount of electricity used by a gadget to operate continuously is known as the “running wattage,” while the amount of power needed to start it up is known as the “starting wattage.”
Here is the whole list of refrigerator wattages. Check how many running and starting watts your refrigerator and freezer have:
|Refrigerator And Freeze||Starting Watts||Running Watts|
|Small-Mini Fridge||200 watts||50 watts|
|Big-Mini Fridge||400 watts||100 watts|
|Standard Energy-Star Fridge||768 watts||192 watts|
|Small Fridge||1,200 watts||400 watts|
|Standard Fridge||2,900 watts||700 watts|
|Biggest Fridge||6,000 watts||1,500 watts|
|Big Side-By-Side Fridge||4,000 watts||1,000 watts|
Calculating The Total Wattage And Amperage Requirements
Next, add the beginning and operating wattages of the refrigerator and freezer to get the needed total wattage.
For example, if your refrigerator requires 800 watts of running wattage and 1500 watts of starting wattage, and your freezer requires 500 watts of running wattage and 1000 watts of starting wattage, you’ll need a generator that can handle at least 800 + 500+1500+1000=3400 watts.
Next, review the model’s specs to establish the amperage needs of the refrigerator and freezer. To get the total amperage needed, add the amperage needed for the freezer and refrigerator together.
Selecting A Generator That Can Handle The Total Wattage And Amperage Requirements
Once you know how much overall wattage and amperage you’ll need, you can choose a generator that can meet those needs. To make sure that the generator can handle any possible rise in wattage or amperage during start-up or defrost mode, it’s crucial to choose one with a larger output than the entire amount of wattage and amperage needed.
It’s crucial to remember that this is only an example, and the precise amount of generator required may vary based on the individual appliances and gadgets you want to operate.
How To Calculate Wattage Requirements
As a practical example, here is how to calculate your minimum wattage requirements:
- On average, a standard refrigerator requires 600 watts. As a result, it will consume 600 Wh for every operation hour (watt-hours). A 10-hour operation of a freezer will consume 600 Wh multiplied by 10. (watt-hours). 6000 Wh + 600 Wh = 6600 Wh if the freezer and refrigerator are both operating (watt-hours). Your generator should have a minimum operating capacity of 6.6 kWh (kilowatt-hours).
- Another practical example: It may be a refrigerator plus a chest freezer or one huge upright freezer if your appliances utilize a combined 8 kWh for cooking, heating, and other daily purposes. The device may run up to half that time on an 8 kWh generator without adding a generator to the load.
Suitable Size Generator To Run Refrigerator And Freezer
- Most households operating a refrigerator, freezer, and other appliances simultaneously without tripping an overload circuit breaker should be able to do so with a 10 kW generator. To avoid overloading them, all the generators you use should be the same size. Before buying a generator, be sure to determine your wattage needs.
- A transportable inverter generator is an additional choice for the house. Appliances with motors or heating components, including a stove, furnace, and more, may be powered by a 12,000-watt inverter generator. The advantage of an inverter over a typical generator is that it maintains a steady 120 Volt AC voltage. Inverter generators are perfect for starting delicate equipment, such as computers and TVs.
However, you will need a generator with a transfer switch to power a sizable oven or commercial refrigerator in your restaurant or company that needs heavy-duty 240 volts of electricity. As a result, the appliance will be able to supply a 240 VAC appliance with a dedicated circuit while still operating on 208 VAC. A generator that can run a commercial refrigerator of this size would need to be considerably more powerful—at least 25 kW–75 kW.
When you need electricity the greatest, the proper size generator will provide it without overloading it or harming refrigerators or any appliances. Many generators with capacities ranging from a few kilowatts to hundreds of kilowatts are available for residential and commercial usage.
Some generators can even be linked to solar energy systems so that they are off the grid. Before investing in a generator, make sure to determine your wattage needs.
