Now let’s get started!

How Solar Power Fridges Work

Fridges that have the ability to run on solar power are essentially 12V fridges, also known as portable fridges. Unsure what that means? These cool appliances are built to run on battery power rather than shore power!

Your solar panels directly recharge and maintain your RV’s batteries, should you have solar installed. That’s how your fridge would technically be “solar powered”- solar can power DC or battery powered items with ease.

12V fridges work the same as regular shore power fridges, except they usually have more portable elements to them, such as a manageable size and weight, wheels, and a handle. It is important to outfit your RV with a reliable battery for boondocking if you have a solar fridge.

Solar fridges come in a variety of shapes, styles, and capabilities. Most of them have freezer compartments, ample storage for cans or bottles, and some are even high tech enough to be controlled via a mobile app!

These fridges are built with portability and ruggedness in mind. They can easily be installed in your RV or Class B van conversion– you can hit the road knowing that you don’t have to worry about keeping your food cold!

What to Consider in an RV Fridge With Solar Power

There are many things to consider in an RV fridge built and ready to be powered by solar energy. But what might some of those considerations be? Let’s take a moment and look at some together.

Size

Whether you’re in a vintage travel trailer or a brand new Class B van, size matters. It can be difficult to fit all the amenities you need in a tiny space, especially if you aren’t used to the size of RVs. Even finding a small rig with a bathroom and shower is possible, however!

That is why considering what size portable fridge you need is very important. You may only have so much space available to you, whether it be inside of your RV or tow vehicle, and that space will always be at a premium.

Some RV fridges that run on DC power can be installed where an old RV fridge used to be- some portable fridges look and operate more like a traditional cooler or ice chest. This means that the dimensions might be very different than what you may be expecting.

Trying to figure out how much space you need may be difficult, especially because most portable fridges are measured in cubic feet. How much food does that mean you can fit? I recommend taking some measurements of your residential fridge to get a good idea.

The size of your fridge will also affect your budget. If you are looking at something larger than the average portable fridge, it will of course cost you a bit more. However, this can be necessary for those of you camping with a large group or for an extended period of time.

Fridge or Freezer Capabilities

Whether you need your 12V fridge for keeping your beer cold or for freezing your ice cream, having the option to do both can be very beneficial to many RVers. That’s why knowing the fridge and freezer capabilities of any portable fridge is key.

Some portable fridges only have one large compartment, meaning you have to choose between using it as a fridge or as a freezer- you can’t have both at once. This can be frustrating for many RVers, though it may save you some funds in the long run.

However, there are portable fridges with two compartments so you can have frozen french fries for deep frying and fresh burgers for grilling on some of the best portable RV grills available on the market today.

It all depends on what you plan on using your portable fridge for! Most RVers will choose a fridge with both options, as it can feel difficult to pick between one or the other. You shouldn’t feel as though you have to limit your food options in that way.

No matter what, keep the size of your fridge in mind: your freezer compartment may be much smaller than the one you have at home. The last thing you want is to end up with ice cream that can’t fit (though I guess that means you’ll have to eat it all, and that doesn’t sound so bad)!

Other Power Options

While having a 12V fridge may be all you need, some RVers may want the option to hook up their fridge to other power options. For example, if you want to plug in your portable fridge at home, shore or 120V AC power is going to be a lot more efficient to use than 12V DC power.

You’ll want to shop for a fridge or freezer with these capabilities, and it usually just comes in the form of a particular power cord- one that can easily plug into a standard socket in your home rather than a cigarette lighter in a car.

You may even find a more traditional three-way powered RV fridge and think that it suits you. These fridges are capable of running on AC, DC, and propane power sources. This is the ultimate in versatility, but you may lack some portability with this option due to propane lines.

Many RVs built for boondocking have fridges like this installed in them already. Having as many power sources as possible means you avoid spoiled food in the long run, but it may not suit your current solar power fridge goals!

Efficiency

 What’s the most important thing to consider if you are boondocking or camping off-grid for a long period of time? You’ll need to consider the efficiency of your appliances so that you can maximize your overall energy usage!

Understanding your RV’s electrical system can be more complicated than you think. There are many things to research and understand before you hit the road and go off-grid, such as your expected amperage used hourly, how powerful your batteries are, and if you have an inverter.

Before you begin shopping for a solar power fridge, you should understand how much power you have, how long that power will last off-grid, and then begin your search looking for fridges that will fit into your expected amperage usage in an efficient way. 

Choosing an energy efficient appliance can be key to successfully camping off-grid, especially if you plan on doing so for long periods of time. You don’t want to run down your batteries, so it is important to also have enough solar panels installed to properly maintain them.

Where You Plan on Storing It

Not only does the size of your solar powered fridge matter- you should think about where you plan on storing it while you are camping. Yes, space is always at a premium in RVs, even in RVs with enough space for two bathrooms!

This is when many RVers resort to keeping things outside of their RV if the weather is nice, and this could include your off-grid fridge. If you are unsure where a good place to keep your fridge might be, you may wish to consider a more durable option.

You could potentially keep your solar powered fridge outside in the elements, should you not have enough space inside. This can be especially true if you plan on cooking much of your food outside, or if you’re boondocking in a teardrop travel trailer with an outdoor kitchen.

Some of these fridges should only be kept indoors, and aren’t recommended for extended outdoor use. This is something to consider, and durability and ruggedness may be near the top of your list of needs!

Overall Power Needs

Choosing a solar fridge with more bells and whistles could mean more power usage. However, you’ll want to get a fridge or freezer that will stay cold for a long time. Budgeting enough power for your fridge when you’re travelling off-grid can be tricky.

To truly gauge how much electricity something needs, I highly recommend purchasing a multimeter. These nifty gadgets are capable of measuring electric currents in many different forms, including amperage. They are invaluable if you own an RV!

Trying to calculate how many solar panels you need to power your boondocking rig can be complicated- it is important to know how much power every single appliance needs, both to start up and to stay running. Take your time to determine your power needs and wants!

Budget

Lastly, knowing roughly what you can budget for an RV fridge is important. These necessary appliances range in price, anywhere from a few hundred dollars to a couple thousand dollars. Purchasing a portable fridge may be a big investment for some of you.

The startup cost of a solar powered fridge can be high as well. If your RV isn’t already outfitted with solar panels, you’ll have that cost to consider as well. You may even have to pay for an upgraded converter, another cost.

However, these fridges are versatile, portable, and can be used in a variety of applications. You may be surprised by how much you can fit in them as well- perhaps you won’t need as big of a fridge as you expect, and that way you can save some money!

Pros and Cons of an RV Fridge With Solar Power

There are many perks and drawbacks to anything, and RV fridges for solar power operations have their own pros and cons. Let’s take a look at some of these possibilities together.

Pro: They Run on the Sun

If you are a notorious boondocker hoping to hit the road with no connections or hookups, having a fridge that runs on solar power is a huge perk. You won’t have to worry about anything but your battery life, and this should be replenished daily by your solar panels.

Solar on RVs has taken off, for many reasons. Having the option to go anywhere you want so long as there’s sunlight can be freeing. And having a fridge that will run on the sun is even more wonderful!

Con: It’s Risky if Your Fridge Runs Out of Power

One of the main risks of being disconnected from shore power? What will you do if your solar malfunctions or your battery runs out of power? You run the risk of everything in your fridge or freezer spoiling.

Understanding your RV’s electrical system, including your inverter and converter, is key to making the most of your solar system. Knowing how many amps that your appliances take is detrimental, especially before you hitch up and go.

Pro: They Are Compact and Portable

There’s nothing like an ice chest or cooler for days on a boat or at the beach. Solar power fridges are no exception, capable of going wherever you choose to bring it. So long as it has a handle, wheels, and a battery to run it, you can bring your cold goods!

Plus, having a compact and portable RV fridge means that you don’t have to worry about where to keep it when you’re on the road. You can easily slot these fridges into awkward spots in your van conversion or travel trailer built for solo travel.

Con: Sometimes They are too Compact

The main drawback of RV fridges that run on solar power? Some of them are quite small. If you consider a standard ice chest, that is the average size of most of these fridges and freezers- while some boast large capacities, it may be less than you expect.

That’s why it is important to plan ahead- consider how many fridge or freezer goods you need for one camping trip, and if you can afford to restock rather than bring everything in one go. Either that, or you purchase a larger fridge- but that may take up too much space!

Pro: They are Easy to Set Up

Concerned about how to hook up your solar powered fridge in your RV? The best part of these little guys is that they are simple to set up, and for a good reason. Most will have a standard cigarette lighter-style plug- simply insert that wherever you plan on running your fridge!

So long as you have your solar system up and running (or perhaps you have an onboard generator), you should have no trouble using your solar powered fridge. Many boast quick cool down times as well, which can be an added bonus to these portable appliances!

Con: They Can Get Pricey

Just like a lot of RV parts and accessories, solar powered fridges can get expensive. Plus, their prices range wildly- from $300-$3,000 and anywhere in between. It can be difficult to know what to purchase, let alone if you can even afford one in the first place.

RV replacement parts or build outs always take a decent amount of cash. Replacing a standard RV fridge with a fridge for solar power is no exception. You may be faced with some sticker shock, and this can get discouraging while shopping.

Pro: You Can Get Fridge and Freezer Capabilities

You can get an RV fridge for solar power with freezer options as well- you won’t be stuck with only fresh food options if you don’t want to! These technological marvels can come equipped with a small freezer section too, in case you need ice or more.

Having the option of both a freezer and fridge makes your cooking possibilities limitless. You can make just about anything- just make sure you’ve packed the propane and that your propane regulator is up to date (check out our regulator guide here, if you think you need a new one)!

FAQs About Solar Powered Fridges and RVs

Still have questions about what the best RV fridge for solar power is? Before we get to the products, let’s answer some common questions first!

Do I Need an RV Fridge that Runs On Solar Power?

No, you don’t necessarily need a fridge that runs on solar power. However, if you have solar panels set up on your RV, there’s no reason not to upgrade. Having the ability to go completely off-grid can be freeing, and fridges are often something that holds RVers back.

You may have a powerful enough converter that can change your standard fridge’s AC power into lesser DC power, meaning you can run all of your RV off of your batteries. However, this significantly limits your power consumption if you don’t have the ability to recharge your batteries.

That’s why having a fridge that runs on solar power can be valuable, especially if you have a full fridge of food. You’ll want to keep things cool, especially if you are travelling from one destination to the next.

Are Solar Power Fridges Better?

Solar power fridges aren’t necessarily better. But they can suit your lifestyle and RV circumstances better than standard fridges sometimes! This is definitely the case if you boondock frequently and want to get off the grid often.

Solar power fridges are smaller than RV fridges on average, but many of them are portable. Complete with wheels and a handle, you can transport these glorified ice chests anywhere you want! That’s another huge perk to these appliances.

How Much Power Do I Need for My Solar Power Fridge?

It will depend on the fridge that you eventually purchase. Some portable fridges use as little as half an amp per hour; others have a much larger draw, closer to 5 amps or more. It depends on what the fridge and freezer are capable of.

You will need to consider a reliable and high output battery for running your RV off-grid. Unless you have recently purchased a much more luxurious rig, getting your power system sorted should be a priority. It’s easier than you think, once you get the hang of it!

What are Some Good Brands of RV Solar Power Fridges?

There are many brands of RV solar power fridges on the market today. However, some names remain popular and reliable. Some of the good brands are:

• Dometic

• RecPro

• Whynter

• Bodega
• ICECO

There are many more brands, and many more on this list, but those are some of the top recommended brands available currently. You may even recognize Dometic and RecPro from our other RV product lists, such as the most efficient air conditioners for your RV!

What is the Most Energy Efficient Fridge for Solar Power?

The most energy efficient fridge for solar power depends on what you are looking for and how large of a fridge you need. Keeping an eye out for fridges that cool down quickly and use only a few amps at a time while running is a good idea. 

From this list, some of the most energy efficient solar power fridges include brands like Dometic, ICECO, and RecPro. You’ll want to check out the running amps and how often your fridge is turning on and off- this is a good idea for figuring out efficiency.

How Many Solar Panels Do I Need to Run My RV Fridge?

It will depend on the overall wattage of the panels and how many watts your RV fridge needs to both start up and run consistently. However, the average wattage needed for portable fridges is roughly 200-400, depending.

That means you should consider at least three solar panels in order to maintain power to your fridge for a camping trip. And this is just the fridge alone- you will need more powerful panels and even more of them in order to power the rest of your RV. 

But most RV manufacturers can help you out with this. It can be difficult to determine just how many you might need, especially if your needs fluctuate. You can always consider purchasing a generator to help you power your rig, especially some of the best generators for your RV air conditioner!

Conclusion

Purchasing an RV fridge for solar power is a wonderful choice if you love to dry camp or get off the grid. Plus, you can bring most of these portable fridges to your next tailgate or party and use it for years to come, both in and out of your rig!
