What Is The Power Consumption Of A Refrigerator?
“When selecting a generator to power your refrigerator and freezer, it is important to consider the wattage requirements.
The owner’s manual and manufacturers’ tags will provide information on the running and starting wattage of your appliances. The starting wattage, also known as surge wattage, refers to the energy needed to start the appliances, while the running wattage, also called the rated wattage, indicates the energy consumed after startup.
Home refrigerators typically require 1000 to 2000 watts. For efficient power supply, choose a generator with a starting wattage of at least 2000 watts. For added safety, a larger generator is recommended, which can also handle the energy needs of other household items such as televisions and lights.”
Tips for Selecting The Right Generator Size For Your Refrigerator
“It is crucial to take these factors into account when choosing a generator.”
1. Generator sizing for refrigerators
“Determining the energy consumption of your fridge or freezer is crucial in selecting the appropriate generator. Fridges and freezers tend to consume a large amount of energy, with older appliances requiring even more.
The power requirements for the refrigerator can be found on a sticker inside the door. A 6.5-amp rating for the fridge means a generator with an average operating wattage of 780 watts (6.5 amps x 120 volts) is needed. Keep in mind that the compressor motor of refrigerators and freezers may cause a power surge of two to three times the average running wattage during start-up, so a generator with a power output of 1,560 watts is recommended.”
2. Identifying the generator type
“When selecting a generator, it’s important to consider the type that best suits your energy needs. You can choose from diesel, gasoline, propane, natural gas, and even solar energy.
Other factors to keep in mind include the type of installation you prefer, the equipment it will power, and the location of the generator (outside or inside).”
2.1 Gasoline
“Gasoline is a popular choice for portable generators due to its ease of access and use. One advantage of gasoline-powered generators is the noise reduction they offer through regulating engine speed with an inverter generator. The level of noise reduction will vary based on the load being placed on the generator.”
2.2 Propane
“Both portable and installed generators can run on propane, which is a widely used fuel source. Propane-powered generators are known for being cleaner and quieter than gasoline models, making them a more desirable option.
Additionally, inverter generators that run on propane are also available. The market offers a range of options, including gasoline and propane models.”
2.3 Natural Gas
“For permanent installations, natural gas can be an excellent option if it is easily accessible. It is known for being user-friendly and silent.
However, there is a key requirement – a gas line must be present in the house or building. This line often provides energy not just to the fridge, but also to other necessities like air conditioning and lighting.”
2.4 Diesel
“For rural areas without access to a gas line, diesel generators can be a great solution. The high power and large size of diesel motors make them ideal for handling heavy loads, such as in hospitals. However, they can be very loud, so they may not be suitable for residential areas where noise may be a concern.”
2.5 Batteries
“Battery-powered generators have the advantage of being suitable for indoor use.
They are also simple to install and can be recharged through either solar energy or electricity. It is recommended to replace the batteries every four years to ensure efficient operation.”

Calculating Generator Wattage
The first step in determining the right generator size is to calculate the wattage that your refrigerator requires. The wattage of an appliance can be found on its label or in its manual, but if it’s not available, you can use the following formula to calculate it:
Wattage = Volts x Amps
In most cases, refrigerators run on 120V. Next, determine the number of amps the refrigerator requires by checking its label or manual, or by using a device called a clamp meter that measures the current flowing through the appliance’s cord.
Once you have the number of amps, multiply it by the voltage to determine the wattage required to run your refrigerator. For example, if your refrigerator requires 4 amps, the wattage would be 4 x 120 = 480 watts.
Generator Size
The next step is to choose a generator that can provide enough power to run your refrigerator. A general rule of thumb is to choose a generator with a maximum output of 25% more than the wattage required by your refrigerator.
In our example, the refrigerator requires 480 watts, so you would want to choose a generator with an output of at least 600 watts to ensure it runs efficiently. Keep in mind that some generators have a rated output and a surge output, which is the extra power the generator can provide for a short time when the appliance is first turned on.
Fuel Type
Another important factor to consider when choosing a generator is the fuel type. There are two main types of generators: gasoline and diesel. Gasoline generators are usually smaller and more portable, while diesel generators are larger and more fuel-efficient.
If you’re planning to use the generator for short-term power outages, a gasoline generator may be the best choice. If you’re planning to use it for long-term power outages, a diesel generator may be a better option.
