Mini fridges are becoming a common commodity for modern households, especially as secondary storage and cooler options. Knowing alternative ways to power and run your minifridge will be helpful to keep things efficient. Speaking of alternate ways to power your mini-fridge,
Can I run a mini-fridge off an inverter?
Mini fridges can run on inverters. To run your mini-fridge off an inverter, you have to make sure they are the right one, as in they draw enough power to avoid shorting your machine. You also need to keep in mind the start-up surge as it is higher than what it draws and the accurate batteries.
Now that you know you can run your minifridge off an inverter, here are a few tips so you are set on the right track.
Check the power draw:
One of the first things you have to do is check the power draw of your fridge in watts. As mentioned earlier, fridges can run on one stable draw but have a stronger start-up surge.
Make the power draw calculation beforehand:
If you plan to use multiple devices off of the inverter, make sure to add it into the calculation and check the information of every device you plan to use.
Know how long the mini fridge runs per hour:
Check the intermittent nature of your mini fridge since they don’t usually run continuously, you need to know how long they are running each hour. Not doing this could result in shortening your machine.
Choose the right battery for the inverter:
This goes without saying but choose the right battery and inverter that suit your needs. The less you use, the more you will have and the longer your supplies will last.
How big of a power inverter do I need to run a mini-fridge?
If you want to know how you can run your mini-fridge on an inverter and what power you need from it, there are a few things you need to keep in mind.
Since the inverter needs to supply two kinds of needs (peak or surge power and the usual continuous power) it is important to know what power your designated mini-fridge needs.
Here, surge means the maximum power your inverter can supply, though it is usually for a short time. Typically, this short time means no longer than a second, unless specified otherwise.
The usual continuous flow of power is what they typically supply on a steady basis. Its also known as the continuous rating which is very much lower than the start-up surge.
Fridges generally have the start-up power requirement to be 2x or 3x the continuous typical wattage.
a small mini-fridge could run on a 175-watt inverter, granted it provides the start-up surge needed at boot.
most regular mini-fridges can run on a 300-watt inverter easily.
regular small or mini-fridges (based on 100-400 watts size) can fluidly work with a 400-watt inverter.
a 750-watt inverter should have a start-up wattage of 1500 watts, which is suitable for a wide range of electronics, not only limited to mini-fridges but also microwaves, TVs, and even sound systems.
this inverter is more than capable to run your mini-fridge as well as other machines of your choice.
Mostly too much for a mini-fridge, a 1500-watt inverter can have 3000 watts of surge power and 1500 watts of continuous AC power. Such range is used for typical 16 cubic feet refrigerators.
a 2000-watt inverter can power a wide range of household appliances, starting with your mini-fridge, microwave, coffeemaker, toaster, and even computers.
As you can see, mini-fridges can run on even the smallest of inverters, granted they have to provide the correct amount of surging and AC power.
You might not be able to use all devices simultaneously, but you can calculate running and starting wattage to determine which are compatible.
What size battery do I need to run a fridge?
To run a residential fridge, the minimum power you need is 6 batteries that can total 600-amp hours (where 300 ah is usable) for a smooth 24 hours run.
The average fridge needs 40 watts of electricity per hour. Using this to calculate, for 24 hours you need 960 watt-hours of battery. Power requirement depends on how often you can charge batteries, as well as their capacity and voltage.
How long will a 12-volt battery run a mini-fridge?
A small fridge, or a mini-fridge in this case, can last about 2 to 4 hours on a 12-volt battery. This is If the battery is of the common 100AH variant.
Usually, mini-fridges that can run on 12v are understandably very small and use power only when it is in the RV that’s driving.
How long can you run a mini-fridge off a battery?
How long a mini-fridge can run off a battery depends on how much power it is consuming.
If a refrigerator on average takes on 1 amp per hour, and is the only appliance that’s running on the battery, a 100-amp hour battery should be able to last for about 50 hours before needing to recharge.
A minifridge by definition should need less power, so you can expect more hours from it. As they run intermittently, assume it runs twice the amount of a regular fridge, under the correct conditions.
Can you run a mini-fridge on a car battery?
You can most definitely run a mini-fridge on a car battery. For how long, is the question.
As they need to have a constant source from the car battery to run properly, a typical car battery can run the fridge for about 12 hours.
The math behind this answer is that an average car battery has a 60 AH capacity which a small fridge might pull 100w when it is running. You also have to keep in mind that they run intermittently, so 50w might be their typical steady flow.
How long will a mini-fridge run on a deep cycle battery?
As deep-cycle batteries are built to regularly discharge while using most of their capacity, they can stand repeated charge and discharge cycles.
This means for a fridge that uses power intermittently, a deep cycle battery that has the average 8-hour rate of 180 amp per hour can make it last through a few cycles. People estimate the time to be around 4 hours.
Normally, deep cycle batteries have a cycle life of 1500, if using 30% of their capacity. Meaning, to get the most use out of your deep cycle battery, you need to see exactly what percentage of their capacity is being used.
Can you run a mini-fridge off solar panels?
Solar panels are becoming a popular mode of power for many people, as the conversation is switching more and more to an eco-friendly, green power-centric future.
The good news for mini fridge owners, you can run your device off of solar panels. However, to do so, you need a few additional items. These are-
- Batteries that can store the solar power to be used on cloudy days or during darker hours.
- Charge controller that will smoothly flow the current from the panels to the battery. They also need to be able to protect the batteries whenever there are sudden power fluctuations.
- An inverter that can change the direct current (DC) power of the battery to alternating current (AC) that the mini-fridge can use.
On average, a single medium-sized solar generator can use a mini-fridge for 3 to 6 days, depending on the size. Typically, a solar panel connected to an inverter produces 1kWh of energy per day, if 250 watts x 4 hours are the peak production numbers.
How many solar panels do I need to run a mini-fridge?
How many solar panels you need to run a mini-fridge depends on the size and capacity of the appliance you are running. As mentioned earlier, you can expect a singular solar panel to produce 1kWh each day.
So, if a fridge needs 399kwH to run for a year, you will need 1.1 solar panels to run it. Since mini-fridges are supposed to take less power, 1 solar panel with a proper battery and other devices should be more than enough to run it.
Mini fridges are becoming a common household appliance, and for good reason too. They take up less space while providing maximum storage and cooling.
Knowing the multiple ways you can power it will ultimately help when deciding the power outlet and overall organizing of your space.
