What size solar generator do I need to run a mini-fridge?
As a general rule, a solar generator with a 1.5-2kWh battery is the ideal size to run a mini-fridge. At this size, most mini-fridges can run for about two days before the solar generator needs to be recharged. Most solar generators can also fully recharge while running a mini-fridge.
By utilizing pass-through charging with a solar generator, it can run a mini-fridge indefinitely depending on how much power is being used to charge it up.
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.
How many watts does a mini-fridge use per day?
Most AC-powered mini-fridges use between 500 and 800 watt-hours of power per day. Mini fridges with an Energy Star rating tend to be on the lower end of this spectrum, using about 500-650 watt-hours per day.
If your mini-fridge is an older model or doesn’t have an Energy Star, be sure to review its energy consumption, which can be found either on its attached label or online.
How much solar do I need for a mini-fridge?
A steady solar panel input of 150-200W can keep a mini-fridge running daily via a solar generator. This amount of solar power keeps the solar generator’s battery charged up while using it with a mini-fridge.
However, it’s important to use a solar generator with a large enough battery to run the mini-fridge at night.
There are several types of mini-fridges available today that consume various amounts of power. There are standard mini-fridges, 12V models, and compact fridges for keeping just a few cans of your favorite beverages cold.
Mini-fridges you can use off the grid with a solar generator
There are several differences among my three options given below, but the main variation is each mini fridge’s size.
The best mini fridge for use with a solar generator is the RCA single door mini fridge because it has a 5-star Energy Star rating, a large internal volume of 3.2 cubic feet, and is one of the least expensive mini fridges for its size, at $155.
It also has over 11,000 reviews on Amazon with an average score of 4.4/5. However, the RCA mini fridge may be too large for your specific needs. That being said, I’ve included two smaller models as well.
1. RCA single door mini-fridge with freezer
The RCA mini fridge with a freezer is an ideal system to have on an off-grid cabin if you do not need a full-size fridge.
It can also be a secondary fridge if you have a larger cabin and would like the additional room to refrigerate needed foods and beverages.
Here’s how the RCA mini fridge compares to other models with similar internal volume sizes (3.1-3.2 cubic feet):
| Model | RCA Mini Fridge | Midea Compact Refrigerator | TECCPO Mini Fridge | Euhomy Mini Fridge |

Powering your mini-fridge off the grid (step-by-step)
A solar generator has three core elements that allow it to run your mini-fridge for days/weeks on end (depending on the model you choose): a battery, AC inverter, and a solar panel charging input.
A solar generator of the right size can power a mini-fridge for days or longer depending on the solar input you have connected to the generator.
How to calculate the daily power consumption of a mini-fridge
Here’s an example of sizing your fridge to a solar generator that will work well with it. Let’s say we want it to run for at least a week completely off the grid.
I’m using the Midea 3.1 Cu. Ft. Compact Refrigerator as an example, and its energy use per year is 270kWh per year (as seen below).
Using this number, we need to find out the daily watt-hour (Wh) usage the mini-fridge consumes. This will help align us to a solar generator that will be able to power the fridge for several days if needed.
Taking 270Wh divided by 365 days gives us 0.739kWh of daily usage needs.
Multiply this by 1,000 to get the daily watt-hour consumption, which is 739Wh. Watt-hours are what solar generators use to determine their battery capacity.
Matching a solar generator to a mini-fridge
Playing it safe, I want to get a solar generator that has about double the strength of what the fridge consumes in a single day. Therefore, the best option for this mini fridge is a solar generator with about 1,500Wh of battery capacity.
The generator that I think has the best value in this battery size category is the Bluetti EB150. It has a 1,500Wh battery.
This means that without any solar panels to recharge the generator battery, the mini-fridge in this example will run for about two full days.
Finding the right solar panel input
In order for the Midea mini-fridge to run consistently for days on end, it must have a solar generator with a solar input great enough to keep the battery powering the fridge.
Since the Bluetti EB150 has a maximum solar input of 500W, it will be able to recharge itself fully before nightfall – allowing it the ability to easily power the mini-fridge all night.
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 1,400Wh of capacity, when fully charged, can power a mini-fridge alone for about 48 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
- It is easier to manage without the fear of high voltage because the inverter regulates this
