A mini-fridge is a small refrigerator used for keeping food and drink cold and fresh, and are mostly used in places where a regular refrigerator would be considered a luxury, such as a students’ dormitory, hotel, motel, offices, cars, compact flats, etc.

A mini-fridge is mobile enough to be transported without much stress to any place of desire. It can also be used conveniently and as backup storage even at home on occasions where there are too many items to be preserved. 

Can a solar generator power a mini-fridge?

Yes, a standard refrigerator can run on the power of a single medium-sized solar generator for about twenty-four hours. This means that a mini-fridge can run for about 3-6+ times longer, due to the size differences.

Read on for more details and for some solar generator recommendations for your mini-fridge.

Why a Solar Generator Might be the Best Option to Power a Mini-fridge 

The truth is fuel-enabled electricity, aka gas-powered generators, are loud for any type of indoor use and may not be the type of generator you’d want to have to power your mini-fridge and/or other appliances and electronics. Hence the need to get a solar generator to power your mini-fridge. 

That said, a medium-sized solar generator with about 1400Wh of capacity, when fully charged, can power a mini-fridge alone for about 72 hours, if not more. What this means is that:

  • You need not worry about power outages and contents within the fridge getting spoiled in the process
  • There are no accumulated electricity bills to pay. With a solar generator as the primary power source of your mini-fridge, you can go on a decade or more of non-payment of electricity bills depending on the quality of the generator and how much you use it
  • It is easier to manage without the fear of high voltage because the inverter regulates this

How Much Electrical Energy does a Mini-fridge Take?

A mini-fridge, as the name implies, will take less electricity to run compared to a big refrigerator. The power consumptions of a mini-fridge vary based on sizes, features, and the manufacturer. 

Here are some estimated annual wattages of some popular mini-fridges: 

  • 1.7 Cu Ft Mini Fridges: 208 kWh
  • 3.3 Cu Ft Mini Fridges: 220 kWh
  • 4.4 Cu Ft Mini Fridges: 228 kWh

To get an accurate knowledge of your mini-fridge, you might need to check its manual as there are variances in energy consumption.  

Factors to Consider in Getting a Solar Generator to Power a Mini-fridge

When you need a solar generator to power your fridge, there are a few essential factors that should be put into consideration. 

  • The first factor to be considered is how much wattage your mini-refrigerator can run on. This is crucial because you do not want to buy a solar generator that cannot deliver for its purpose.  This is, to a large extent, dependent on the size of your fridge. You might want to check the average estimated wattages of some popular mini-fridge sizes aforementioned. 
  • Then, you need to be sure that the solar generator you are getting can efficiently supply power to your mini-fridge for a reliable amount of time.

In doing this, you should verify the total wattage that the solar generator is capable of supplying. Getting one that can deliver a higher wattage than your refrigerator demands, and in that process, give your refrigerator and solar generator some breathing space for more efficiency. 

For example, if your mini-fridge demands 500 Watts of electrical energy, you should pick a solar generator that supplies at least 800 Watts. This is so the solar generator would not be running at its full capacity at all times.

A solar generator always running at its total capacity tends to fail quicker than is expected because it puts an enormous strain on its efficiency. 

This also will depend on why you need a solar generator option to power your fridge.

It can either be for support in case of a power outage or as the main power source for it. If the intention is for backup (power outage), then you probably would need one that can last at least a full day.

But if it will be the mainstay of your refrigerator power, then you should get a solar generator that can serve you for days without fail.   

Examples of Solar Generators You Can Trust

Below are three efficient solar generators that you can trust to power your mini-fridge and solve your electrical issues once and for all.

What Other Devices can a Solar Generator Power?

Depending on the capacity of the said solar generator, it is expected that a good solar generator should be able to power most home appliances like a cooker, microwave, etc.

As for electronics, the generator should be able to easily charge computer devices, smartphones, and tablets many times over.

Most solar generators have information on the charge times and capacity for all of the various items it can charge up or power. In some cases, a powerful solar generator can sufficiently run power tools as well.

What is a Solar Generator?

A solar generator is another option for a power supply.  A solar generator, as the name implies, this invention has been built to leverage the power of the sun to produce electricity for use off the grid.

This generator harnesses the energy of solar (the sun) energy to power or gadgets and machines. Solar generators are built with solar panels and batteries that store energy in power cells that disseminate the stored energy to power gadgets, devices, and appliances.

Essential Parts of a Solar Generator

Solar generation is created from solar panels, batteries, and DC-AC inverters.  

The panels are designed to use concentrated solar power to manufacture electricity. This converts into electrical energy and is then transferred to the battery. 

The batteries process the energy gathered and converted by the solar panel and stores it in its battery cells. 

The DC-AC inverter converts power stored in each battery cell to eventually be used for your devices and appliances. 

How Much Energy can a Solar Generator Supply?

Solar generators are manufactured by many different companies and have various sizes.

All solar generators do not have the same storage capacity as the difference is in the intention of the end-user and the components within the generator.
