What is the Best Generator to Run a Refrigerator & Freezer

As a power generator user, you may be wondering what the best generator to run both your refrigerator and freezer is. Many factors are to consider when deciding on this, such as how much wattage each appliance uses, total wattage of your generator, and how long you will need to keep them running for. In order to help you making this decision easier on yourself, it is important that you know about all of these factors as well as some other helpful information regarding generators. Let’s take a look at some of those now!

Sizing the Generator for your Refrigerator:

The most important thing to understand when it comes to sizing your generator for both your refrigerator and freezer, is how much wattage each appliance uses. You can find this information on the label inside of your fridge or on its instruction manual. For example, a typical home refrigerator uses anywhere from 200-500 watts. However, there are refrigerators that are more efficient and use less wattage. If you have any of these generator models, you can reduce the size of your generator or its’ runtime so that it will be able to handle the extra load.

How Much Power Goes a Refrigerator Need?

The next thing, you have to consider is how much wattage your refrigerator actually requires. This can be found in your refrigerator’s manual, which you should have stored away in a safe place in case of emergencies. It’s important to know that most refrigerators vary slightly in both the amount of wattage they require and, in their size, /voltage. Other factors that may alter the amount of power you need include whether or not your refrigerator has a freezer attached to it as well as if there is ice in said freezer.

How Much Power Goes a Refrigerator Use? 

This depends on what is being stored in your refrigerator. For example, a full fridge uses more power than an empty fridge does. Must consider this when you are sizing/running your generator so that you will not have to worry about overloading it each time you need it. As a side note, never run your generator indoors. Only use it outdoors, away from any windows where fumes can leak inside your home.

How Much Power a Freezer Need?

The next thing that you need to look into is how much wattage a freezer uses. This information will be on the back of your fridge’s manual and should list both how many watts it requires as well as its voltage. As with refrigerators, the amount of wattage required by your freezer can vary by model. If you are not sure about: how much power a freezer uses, you can use this information to determine that for yourself. All you have to do is to measure the voltage and wattage requirements listed on your manual and then divide both numbers in half to find the estimated number of watts needed.

How Much Power Goes a Freezer Use? 

Most freezers will use about half as much wattage as your refrigerator does. This is because fridges and freezers typically use similar technology, but with different cooling methods. However, there are certain models that require more wattage than others. Make sure to consider this when sizing your generator so that you will not overload it.


Best Generator Options for Refrigerator and Freezer


Gas Generator Options for Powering a Refrigerator and Freezer:

Next, you need to decide between a gasoline or diesel generator. Gasoline generators are smaller and easier to move around in case of emergency, but they are louder when in use. They also produce fumes that can leak inside your home if used indoors. Diesel generators are larger and cost more money up front, but they are quieter in comparison. They are more efficient in terms of use, so the amount of fuel required to power them is less than it would be with a gas-powered generator.

Using A Gas Generator to Power Your Refrigerator & Freezer:

If you choose to go with a gasoline-powered generator for your refrigerator and freezer, there are a few things you can do to increase its’ efficiency. The first is to have your generator professionally tuned so that it will perform well in an emergency, but also last longer. Most generators need to be tuned every other year for this purpose and should cost around $50-80 depending on where you live. Another thing you can do with a gas-powered generator is to have a power transfer switch installed so that you won’t have to worry about turning it off before switching from the refrigerator and freezer.

Using A Diesel Generator to Power Your Refrigerator & Freezer:

If you choose a diesel-powered generator, there are still some things that you can do to increase its’ efficiency. One is to size your generator properly. The reason that a diesel-powered generator is more efficient than a gas-powered one is because they produce less carbon dioxide per watt of power generated, which means you use less fuel for the same amount of electricity generated. Make sure that you choose the model that is capable of powering both your refrigerator and freezer without going above 50% load, in order to take advantage of this.

Solar Battery Generator Options for Powering a Refrigerator & Freezer:

Another option that you can consider is a solar battery generator. These generators are typically smaller and easier to move around in case of emergency, but also more expensive up front. These generators can also be used as primary power source if your monthly energy bill is very low. A benefit of using these generators is that they use solar panels, which are quieter in comparison to other types of generators. A downside is that they require maintenance and will not be able to power your refrigerator or freezer if the sun isn’t out.

If doing this, we advise having both a solar panel and backup batteries in case the sun goes down. One way to do this with an off-grid solar generator is with a 300-watt solar panel that is able to charge most 12-volt batteries within one day, along with 150-amp hour battery bank.

Using A Portable Generator to Power Your Refrigerator & Freezer:

Last of all you can choose to use a portable generator. This is often the best choice for users that will need to move their generator around frequently for power outages, but also want the ability to keep their refrigerator and freezer on. A portable generator can usually be found in gasoline-powered or solar battery variation so it’s up to you which one you decide is best.

Battery Powered Generators for Refrigerator Powering:

There are also some batteries powered generators for powering your refrigerator and freezer. These can be helpful in case of power outages, but they do require you to keep a number of batteries on hand in order to use them effectively. They also cannot run nearly as long as a generator that is hooked up to propane or natural gas and they usually don’t produce as much power either. The upside is that they are easier to store and take up less space than other types of generators.

Using A Battery Powered Generator to Power Your Refrigerator & Freezer:

You can use a battery powered generator by plugging your appliances into it with an extension cord. This will allow you to use both the refrigerator and freezer at the same time, just as you would with a regular generator. You can also use them in an off-grid mode, but since they are battery powered, they won’t be able to work for nearly as long.

Using A Hybrid Generator to Power Your Refrigerator & Freezer:

One last thing you can do to power your refrigerator with a generator is use it in hybrid mode, which is when you will charge the battery bank by using an off-grid solar power panel, then provide propane or natural gas for continuous power. This allows for great energy efficiency because most appliances are not used constantly and only need to be turned on when needed. It also reduces noise and the need to refuel the generator when not in use.

How To Power a Refrigerator by A Generator:

There are many factors to consider, when trying to power your refrigerator by a generator. You need to know how much wattage it takes during each stage while also knowing the amount of power you have available in watts, then do some quick math to figure out what combination of appliances can run together on that same circuit without overloading anything. Due to the high price of generators and the complexity of running them, it is best to hire a professional for this type of project.

Final Verdict:

When trying to power a refrigerator with a generator, you need to keep everything in mind. You will need a lot of wattage for the initial charge of the battery bank and for running it constantly, so be sure that you have enough watts available before purchasing a generator. Don’t forget about appliances such as air conditioners or other electronics that pull a lot of watts, as they can significantly impact your ability to run your refrigerator and freezer.

Can A Generator Damage A Refrigerator?

One question you may have been whether or not a generator can damage your refrigerator. The short answer to this is yes, it can if the voltage is too high. It will also overheat and blow the circuit breakers on your refrigerator, but luckily there are ways to prevent this.

1- Keeping the Voltage Low on Your Refrigerator & Freezer:

The first issue, you will run into if running a generator for too long is that the voltage will get too high. The best way to avoid this, is by making sure that your fridge or freezer are plugged into a circuit with other appliances, so they all have access to less wattage in total. This can be done by plugging several smaller appliances into one outlet or by using a generator with multiple outlets.

2- Using an Automatic Voltage Regulator for Your Refrigerator & Freezer:

Another way to avoid damaging your refrigerator is by using an automatic voltage regulator, which will automatically regulate the wattage output based on how much demand there is for power. If you need more wattage, it will provide it and if you need less wattage, it will also adjust accordingly. This can be really helpful for those who may not know enough about how to manually do this on their own generator.

3- Using A Solid-State Voltage Regulator for Your Refrigerator & Freezer:

Lastly, some generators come equipped with a solid-state voltage regulator, which is beneficial because it automatically regulates how much wattage your appliance will get without you having to do anything. This can be very helpful for those who are not that experienced with operating a generator or are unable to keep track of everything occurring at once due to other distractions.

4- Using A Relay Center for Your Refrigerator & Freezer:

Some generators also include a relay center, which is basically a big box with multiple outlets. This allows you to plug in more than one appliance, including your refrigerator and freezer, without having to worry about the voltage getting too high or the circuit breakers shutting off. It will automatically regulate it all for you, so there is no need to monitor it closely.
