The Best Battery Powered Generator For Refrigerator When There’s Outage

Power outages happen from time to time in daily life. A series of problems caused by power outages make people distressed, such as the refrigerator stops working, the air conditioner without power, and so on. Especially when there’s outage, the inability of the refrigerator to refrigerate will accelerate the rate of food decay. If there is a lot of food in the refrigerator, it will cause you a huge loss of money when the refrigerator is powered off.

So how to power the refrigerator when the power is off? A battery-powered generator for refrigerator is a good choice when there is a power outage. The battery generator can power your refrigerator and keep it running for 4 to 15 hours. It is a perfect device in time of power outage. 

Why Battery Powered Generator is the Best Choice for Refrigerators During Power Outage?

Generators are often used as an alternative source of energy during an electrical outage to power freezers and refrigerators. The ideal generator is the battery generator for refrigerator, as this eliminates the risk of carbon monoxide accumulation. It's also the quietest generator on the market. It's even better if it's a solar portable generator that can be recharged using the sun's energy.

Amongst the different power alternatives during a power outage, the battery-powered generator is the right choice because of some of its benefits which include:

1. Power your refrigerator at the first time

During a power outage, there are numerous backup options available, but battery-powered generators are the most reliable in terms of supplying totally uninterrupted electricity. They have automated transfer switches that activate quickly after a power interruption, allowing your refrigerators to turn on instantly.

2. Easy To Use

The battery-powered generators for refrigerator is the easiest to install and it is used by plugging the refrigerator directly into the generator.

The battery can be recharged using an electrical outlet, a gas-powered inverter, or solar along with a standard wall outlet.

3. Easy To Move

The portable battery generator can easily be moved with its wheels (for those that come with wheels), a trolley, or an extra hand.

4. Eco-Friendly

It is not harmful to human health as it does not make noise and can be used indoors.

How Many Watts Does A Generator Use

Before you power your refrigerator for the first time using a battery-powered generator – you must check out the following details:

1. Refrigerator Power Consumption

Before settling for a battery powered generator for refrigerator, you should know how much power the refrigerator consumes or will require for it to work efficiently. This will save you from buying a generator that may not be capable of providing the required amount of energy that your refrigerator requires.

Therefore, to find out the number of watts your refrigerator needs. To calculate the accurate number of watts consumed by a refrigerator, a sticker in the refrigerator gives details of the number of amps and volts required, these two numbers (that is volts and amps) must be multiplied together to get the number of watts a fridge consumes.

This, therefore, implies that if a refrigerator has 6.5 amps and 110 V, this means that the total watts to be used by this refrigerator will be 6.5 multiplied by 110 which will be 715watts.

2. Battery Capacity I Need

I heard someone question if a battery-powered generator could operate a refrigerator. Well, you could run anything on a battery-powered generator, but it must be correctly designed, taking into account the load characteristics.

Various electrical appliances, as we all know, require different amounts of electricity to start and run. The first step is to figure out how much electricity your refrigerator uses. This information is also available via the manufacturer's energy rating sticker, which is generally located on the refrigerator's door.

A fridge requires 40 watts of power each hour. If you need the refrigerator to run for 10 hours, a battery generator for fridge with 400 watts will be needed.

A bigger refrigerator requires a battery-powered generator with a bigger power rating while a small refrigerator may use a battery-powered generator with a lesser power rating.

Can A Generator Damage A Refrigerator ?

Surprisingly, a generator that is designed to keep the refrigerator up and running while there is a power outage can also be the cause of its damage, and here is the reason:

For a refrigerator to maintain the right temperature, it automatically switches itself on and off. If a generator has now been overburdened and the fridge is also connected, the thermostat which requires sufficient power to retain the right temperature can damage the refrigerator if it does not get the accurate wattage.

This, therefore, implies that for a generator to work effectively for a fridge, the watt allowance must exceed the refrigerator's starting watt.

For instance, a 2000 watt capacity generator will work effectively with a refrigerator requiring around 1000 watt capacity. 

Therefore, before using any portable power station for refrigerator, the specifications of the refrigerator must be put into consideration.

How To Keep Your Fridge Ready For Any Potential Outage

The feeling of a power failure isn't always a good one. Everywhere suddenly gets silent and goes dark, all the appliances especially the refrigerator now at the mercy of when the power is restored or when an alternative source is provided.

You must be ready to handle a power failure either before it occurs or during the occurrence. The following outlines will be beneficial to you:

1. Do not put any other things into the refrigerator

Putting things into the refrigerator will require the doors to be opened, however, this gradually reduces the length of time the freezer will have maintained its temperature and the fridge is cold. Therefore, when the power suddenly goes out, avoid putting things in the refrigerator.

2. Connect the battery-powered generator to the refrigerator immediately

Where there is a need to keep the refrigerator running either to keep the food in the freezers from getting spoilt, connecting immediately to the battery generator for fridge is important.

3. Keep the doors of the refrigerator close

If there has been a notification of a likely power outage, one of the ways to get the fridge ready, is to maintain a closed-door because it will help to secure the life span of the food already kept in it.

Here is a list of recommended products that have been tested and trusted.


The AC200MAX has a large capacity of 2048Wg and the LFP battery having a life cycle of 3500+ to 80%.

You can use the 3*PV200 PANEL to power AC200MAX. This makes it possible to use solar energy to charge the power station.

The Bluetti AC200Max will run a refrigerator with no stress. It can run a 90-watt refrigerator for 17 to 18 hours.  


The AC300 integrates a solar charge controller, AC charge controller, AC inverter, lithium battery and battery management system into one. It converts clean and environmentally friendly solar energy and grid electricity into clean electricity and sends it to all of your connected loads. 

Note: The AC300 does not have a built-in battery pack, requires at least one B300 connected, and supports up to four B300 battery packs connected, adding up to a total of groundbreaking 12,288Wh.

It will power the following appliances with one B300:

  • Light from A CFL ~ 180hrs

1. Who Are The Battery Generators Suitable For?

Those who desire an emergency backup during the period of power failure.

Those individuals who do not depend on public electricity supply.

Owners of a small vehicle that run on DC current.

Medical practitioners.

Other persons that operate on DC-supplied devices.

2. How Many Hours Can A Battery Power Run Refrigerator?

It takes between 12 to 25 hours to discharge about 50% of the battery. This is best to also preserve the life span of the battery.

3. How To Charge Battery Powered Generators?
