Best Solar Generator For A Refrigerator: Buying Guide
Many brands offer solar generators that can power a fridge.
However, choosing the right solar generator can be overwhelming as it is not a general-purpose device. They can cost quite a bit, and a wrong choice can lead to regret in the future.
It is essential to consider several factors and features to get your hands on a valued purchase. Give this buying guide a read to learn about solar generators for refrigerators.
What Is A Solar Generator?
A solar generator looks just like a fuel generator, except it uses solar energy to power the appliance.
It is a quiet and eco-friendly alternative to a standard fuel generator. The best solar generator for a refrigerator is compact, lightweight, and portable.
It comes in various sizes with varying battery capacities to supply emergency power backup in a power outage situation.
The solar generator is paired with solar panels to convert the sunlight to direct current (DC energy).
The DC power passes through a charge controller and is stored in the battery.
A pure sine wave inverter inside the generator takes the energy stored in the battery and converts it into AC power, ultimately used to power the common household appliances.
Why Is A Solar Generator Better Than A Gas Generator?
Plenty of reasons make a solar generator a better choice than a gas generator for anyone who needs to run a fridge off-grid. Let's have a look at them.
Unlike gas generators, solar generators can be used indoors, thanks to their fuel-free operation.
There is no release of toxic fumes, so you can use a solar generator to run your appliances anywhere in the house in case of a breakdown.
No Fuel Cost
As mentioned above, solar generators use sunlight to run appliances instead of fuel.
It means solar generators can be run at no additional cost, while a gas generator would cost you both time and money every time you go to a gas station for refueling.
The best thing about solar generators is that they require little or no maintenance throughout their lifetime.
Warranties also back these units to save the additional cost of replacement or repair.
Contrary to this, gas generators require fuel and filter changes regularly to work to the fullest.
Benefits Of Using A Solar Generator
Let’s go over the top advantages of using a solar generator.
Solar generators are highly praised for being silent, which allows you to work peacefully.
Unlike gas generators, these units power the appliances without any noise. This feature makes solar generators ideal for RVs and vans on road trips.
Unlimited Power Source
Solar generators use sunlight energy to run your appliances. It can provide unlimited electricity to gadgets as far as the sun shines.
Even on a cloudy day, a few hours of direct sunlight exposure are enough to provide enough juice.
These units can also be charged via an AC outlet or cigarette port in your car.
Operational While Charging
Another significant benefit of a solar generator is using it while charging. The best solar generators for refrigerators offer exact charging and discharging rates in real-time.
It allows you to use the unit and simultaneously charge the generator's battery.
Drawbacks And Limitations
Now that you know the benefits of a solar generator, let's look at the drawbacks.
High Upfront Cost
Solar generators are relatively more expensive than gas generators and other alternatives.
Also, the package does not include the solar panels, so you have to purchase them separately, which would add to the overall expense.
Limited Power Output
Solar generators, being limited to the capacity of their inverter, provide a limited amount of power output. It requires a high-capacity solar generator to run large loads for hours.
Limited Sunlight Hours
The operation of a solar generator depends on the amount of sunlight it can utilize during the daytime.
It works in a limited capacity on cloudy days, making it challenging to use in areas with limited sunlight exposure.
Solar Generators for Refrigerators: Features To Consider
The first thing to consider about a solar generator is how much energy, in watt-hours, it can store.
To run a full-sized refrigerator for 12 hours a day will take a minimum of 1,200 Watt-hours of energy. Mini-fridges and RV fridges typically consume up to half as much energy per day.
So to make sure your generator can power your fridge, check the battery capacity of the unit in watt-hours.
The battery capacity of solar generators range from a couple of hundred Wh to several thousand Wh.
A high-capacity solar generator can of course run a fridge longer. However, remember that most refrigerators are extremely well-insulated and only need to run a few hours per day to keep food and drinks cool and to keep most frozen foods hard.
If you need to freeze liquids, however - for example to freeze fresh-caught fish - then you will need a higher-capacity generator capable of keeping it running 24 hours a day.
The rated output of a solar generator, in watts, defines the maximum power provided by the solar generator, which then determines what appliances can be powered from the unit.
For powering a full-sized 115V fridge, you will need a power rating of at least 500W with perhaps a 1,000 watt surge or peak power rating. Most solar generators with a proper capacity will easily meet this spec.
Solar generators in the 1,000Wh to 3,000Wh class are not generally suitable for powering commercial refrigerators and freezers that require 220V AC power.
Number Of Ports
You must check the types of ports available on the solar generator to know if it can serve versatile applications.
You can use a couple of high-voltage ports to plug in your refrigerator, while the low-voltage AC ports can run low-power gadgets like laptops, tablets, and TV.
Most solar generators also feature different types of USB ports to allow you to plug in USB cords to charge smartphones and power lights and fans.
Apart from the technical features, you should consider the build and design of the solar generator, especially if you plan to use it outside.
A high-end build is essential if you intend to take the generator around on camping and road trips.
The latest generation of solar generators capable of powering a fridge have compact dimensions and weigh between 15 and 60 lbs, so they are easy to move around.
That said, if you are considering a higher-capacity model to serve multiple needs, then be aware some can weigh north of 100lbs.
Maintenance & Operating Costs
Solar generators are low-maintenance machines that require very little care to function properly.
They do not need fuel to operate, plus there are no moving parts on these units.
However, it is still essential to clean the solar panels and regularly remove the dirt and debris from fan air intakes.
These units operate on solar energy, which is FREE. Thus, there are no additional operating costs after buying the solar generator.
Who Needs A Solar Generator For A Refrigerator?
Compact and portable solar generators can keep your food saf and cold in wide range of scenarios.
What size solar generator is needed to run a refrigerator?
Solar generators with a capacity of 2400Wh and higher are suitable for running a large refrigerator 24 hours a day.
However, if you have a 12V mini-fridge and do not want to take a large and heavy generator on an RV, a 500Wh unit should work well enough.
Keep in mind that today’s refrigerators do not pull power all of the time to keep food cold.
And RV-class refrigerators are super-efficient when not pulling power, which extends their life on battery power.
What size generator do I need to run a refrigerator and freezer?
A generator with a 2400Wh capacity can efficiently run a refrigerator and freezer.

How long should I run my generator to keep my refrigerator cold?
In general, you should provide power to your fridge for one hour to keep the refrigerator cold for four hours.
This also depends on multiple factors like how old the refrigerator is and how quickly the temperature changes in the fridge.
How long can a solar generator run a fridge?
Due to domestic refrigerators typically consuming anywhere between 1-2KWh a day, you will require a solar generator featuring 2400 Wh or higher if you wish to keep the fridge running for 24 hours continuously.
Weaker generators should be able to help your fridge run for a couple of hours depending on their Wh rating.
That said, most modern refrigerators don’t need to pull power continuously to keep food cold. So cycling the power on and off can extend the range quite a bit.
How much power does a fridge consume at any given time?
