Choosing the Best Battery Backup For Refrigerator During A Blackout
Of all the electrical luxuries you might miss during a power outage, a running refrigerator is probably pretty low on your list. We are all concerned about making sure our phones are charged, our lights are working, and our environment is comfortable via heating or cooling. Although these things are important, nothing should supersede your need to keep your food fresh and edible. Hence, it's quite necessary to prepare by having a battery backup for refrigerator equipment in your home.
Even though many of us can be happy living off of non-perishables such as canned goods and packaged items for a short time, after a while, we’re going to want something more fresh and healthy. This is why we keep refrigerators in our homes. Fresh fruits, meats, eggs, cold beverages, and more are conveniences we take for granted. We fill our fridges with hundreds of dollars worth of foodstuff. Without the power to keep it running and keep our food from spoiling, we could run into trouble. I mean, going hungry is one thing. Feeling nauseated and ill due to eating spoiled food is almost ten times worse!
There are options to keep your refrigerator as cold as possible without power. Filling the fridge with bags or blocks of ice like a glorified cooler is an option. Finding some location to sell you dry ice is another. Some people even consider wrapping their refrigerators in insulated blankets. None of these seem particularly convenient. With today’s technology, there’s no reason why you shouldn’t have some kind of backup power at the ready to keep your refrigerator humming. Here are a few options to consider.
The Four Most Popular Options for Refrigerator Backup Power
Whole-House Generators – These large units take up a lot of space, but they will provide uninterrupted power to your entire house. Many times, these units will engage immediately once a power outage is detected. Some run on natural gas and connect directly to your supply. Others run on gasoline or propane and will need to have the tank refilled from time to time. As attractive as it is to know that life can go on as normal, the cost of a whole house generator is substantial. Also, you will need to have room for the unit as they are quite large.
Battery Backup for Home – Another expensive but viable option is to have a home battery backup system installed in your home. This involves the addition of solar panels attached to your roof and battery storage secured in your home. You will need to know which system is right for you (grid-tie, off-grid, and hybrid) and you’ll need to know the amount of battery storage the suits your typical power usage.
Gas Generators – Almost everyone is familiar with gas generators. Modern gas generators run quieter and cleaner than they used to. They won’t power your entire house, but they will be able to manage the power for most critical items, such as your fridge, some lighting, and recharging phones, tablets, and laptops. A big drawback is the unit can not be used inside due to its exhaust emissions being poisonous. And bringing power from an outside unit into your home could be tricky since you’ll have to leave a door or window cracked open for the extension cords. Also, you will need to constantly check your fuel supply.
Solar Generators – Solar generators kind of give you the best of both—or should I say all—worlds.
First, top-quality units can power all of your critical needs.
Second, these generators can be brought indoors for use since they emit no toxic fumes.
Third, they do not need to be “refueled” only recharged periodically.
And fourth, they are a lot less expensive than whole-house solutions. Since most of them are portable, they can be taken from inside the home and outside to be attached to the solar panels for recharging.
Finally, the cost of “fuel” for a solar generator. Zero dollars since the sunlight is free for all. And that’s the best price.
Advantages of Portable Solar Generators as Battery Backup for Refrigerator
Simple to use
These units are literally plug-and- Your refrigerator will plug right into one of the outlets on the unit and will have access to full power as needed.
Rechargeable giving you an endless supply of power—that costs you nothing
- Very little difficulty relocating your portable power station
Using a solar generator to run your refrigerator is incredibly convenient, but at times, your backup power supply will need to be recharged, most of them can be charged by connecting to a wall outlet or using solar energy. Of course, one could simply figure out a way to run cables from the solar panels located outside directly to the battery powered generator. Thankfully, solar generators are easily relocated. To take advantage of the solar rays eager to recharge your unit, simply bring it out to where the solar panels are placed for optimum recharge time. Be mindful that, while your refrigerator is not being powered, it would be best to keep your doors closed (or opened and closed very quickly) to avoid “losing your cool.” Soon enough, you will have your refrigerator back on the juice with the option to open your fridge door as often as you’d like.
There are other solutions for backup power to consider, but these four will be the most prominent ones available to you. The option that seems to make the most sense is a portable solar power station as your backup battery for your fridge. Depending on your selection, though, you will need to make sure your refrigerator and your power supply are a match.
What Size Generator Is Needed to Run Your Refrigerator And Freezer?
Finding the perfect generator and battery backup for refrigerator equipment is critical to keeping your food cold and safe to eat. It is necessary to select the unit that has enough power so you do not run into issues. Since most refrigerators and freezers use between 100 and 800 amps per hour, be sure to check the specifications of the generator or battery backup you’re considering.
As for the wattage, you’ll need to consider not only the running watts but also the starting watts. If you’ve ever sat in a quiet kitchen, I’m sure you’ve heard the fridge motor kick on. If the generator’s wattage is too low, you could run into issues trying to power your refrigerator. Here are a few types of refrigerators and their usage.
- Mini-Fridge – Running watts around 100, starting watts around 140.
- Side-by-side Fridge – Running watts around 790, starting watts around 300 to 600.
- Smart Fridge – Running watts around 300 to 500, Starting watts around 350 to 750.
As you can see, there is a wide array of power usage to consider, depending on your particular refrigerator. If you are feeling overwhelmed, just remember that a standard 15 cubic-foot refrigerator can be powered comfortably with a 1200 to 1500 watt refrigerator battery backup unit or generator.

Best Practices to Use with Your Refrigerator During A Power Outage
Whether you have power running your refrigerator during a power outage or not, it would be wise to follow a few conservative actions to keep your fridge not only full of edible food but full of cold air.
One thing you can’t do during a power outage is pulled open the door of your fridge and longingly stare into the vast array of foodstuff you’re trying to keep cold! What you’re doing is letting out all the cold. Actually, you’re replacing the colder air inside the fridge with warmer air from the outside. As you stand there with the door open, the temperature inside the unit will continue to rise. And without power, your refrigerator does not have the ability to bring that temperature back down.
Food starts to spoil when the temperature rises above 40 degrees. At this point, you only have about two hours in which you can either return it to cold conditions or cook it. It is imperative you keep the door shut and your temperature as low as possible for as long as you can.
Before Accessing, Make A List
If dinner time is approaching and you need to get food out of the refrigerator, it’s best to make a list of everything you need BEFORE you pull open the door. If you quickly grab your protein, salad makings, and beverages and then rapidly slam the door shut—but come to realize you forgot to grab the salad dressing—you will need to reopen the door, and that’s even worse. Make a complete list of all your cold foodstuff, then open the door, quickly retrieve what you need, shut the door—and then breathe easy knowing you’ve got all you need.
Before Putting Away Leftovers, Let Them Cool Off
Placing a hot container in a refrigerator is a double-whammy. First, the obvious; your fridge will need to cool the hot food. Second, by placing hot food in a fridge, you increase the amount of humidity in the space…humidity that your fridge will need to remove. It seems logical, but it’s not in the front of our minds. Let the food cool as close to room temperature as possible (remember, you only have a couple of hours before it will go bad) then refrigerate.
Keep Your Refrigerator As Full As Possible
This might seem counterproductive but having a full fridge actually helps you conserve energy and creates an environment where your refrigerator will not need to run as often. This happens in two ways. First, the solid objects, once they have reached the optimum cool temperature, are easier to keep cool than the empty air around them. Think about it this way: which stays colder longer, a glass full of water or a glass full of ice cubes? With less air to cool, your refrigerator won’t need to work as hard to keep temperatures at the proper level.
Second, whenever you open your refrigerator door, the colder air inside the fridge is displaced by the warmer air from the room. If your refrigerator is full, there is less cold air to be replaced by the colder air. And the cold objects will barely drop in temperature.
I’m sure these are tips you’ve never considered, but even with a generator or battery backup for your fridge, these tips will go a long way in keeping your food edible and your power consumption at its lowest.
A Battery Backup For Refrigerator Could Be A Lifesaver
With the amount of money we all invest in our food, we have the expectation that we will be able to enjoy that food before it expires. With refrigeration, we have no doubt about this. When a power outage inevitably hits, that expectation takes a hit. Having some sort of battery backup for your refrigerator takes the uneasiness out of the equation. Especially in areas with frequent power outages, the peace of mind one gets from knowing all that food stored in refrigeration will still be edible long after the power cuts out makes investing in a refrigerator battery backup and power solution worth the time and money.
