So you are in need of an emergency home backup power supply.
One of the most important appliances in your household is probably your refrigerator.
It also happens to one of the most energy-consuming ones.
So the question is: can a portable generator power a refrigerator?
The answer is: it depends.
In the following article, we will tell you how big of a generator you need to run a refrigerator and freezer during a power outage.
We will also show you our recommendations for the best portable generators for refrigerators. If you are in a hurry and simply want to know which generator is reliable and powerful enough to run a refrigerator – we’d recommend you have a look at Champion 3400 Watt Dual Fuel Generator.
How Many Watts Does a Refrigerator Needs?
Every refrigerator is different and each of them has slightly different wattage requirements.
The best thing to do is to check your owner’s manual to look for this information.
You can also usually find this info on the manufacturer’s tag.
Note that there are two numbers you should pay attention to – starting watts and running watts.
Starting wattage (AKA surge wattage) refers to how much energy you need to start your refrigerator and freezer.
Running wattage (AKA rated wattage) is the power you need to run the appliance continuously after the initial startup.
On average, depending on their size, home refrigerators need around 1000-2000 starting watts.
The generator that can deliver at least 2000 starting watts will be sufficient to run both the refrigerator and the freezer without problems.
However, we advise you to get a slightly larger generator just to be 100% on the safe side.
A larger unit would also give you some more spare power to run a few other things in your household such as lighting circuits or a TV.
Which is the best portable generator for a refrigerator?
A good generator that can produce at least 3000 starting watts would be an ideal choice for a refrigerator and a few more household items.
We particularly recommend getting a dual fuel generator. Since propane is cheaper than gasoline, it would save you quite some money on fuel.
Ideally, you should get an inverter generator, as these are much quieter, more portable and 100% safe to use with sensitive modern electronics such as home audio systems, laptops, and TVs.
The following 3 inverter generators are our recommended choices for refrigerators and freezers.
Champion 3400 Dual Fuel Inverter
This generator produces 3400 starting and 3000 running watts of power.
This makes it perfect for running a refrigerator, freezer and several other things simultaneously.
The Champion generator is an inverter type.
It’s much quieter than conventional generators and is perfectly fine to run your TV and other electronic equipment.
The great thing about this generator is that it is a dual fuel unit – you can run it either on gas or propane.
This would allow you to save quite a lot of money on fuel since running a generator on propane is much cheaper than relying solely on gasoline.
You would also get much longer total run time – more than 7 hours at 25% load on gas and 14 hours on propane.
That gives you a very solid 20 hour continuous running time.
Being able to run this generator for so long will certainly save you a lot of headaches during longer power blackouts.
We found the generator to be also pretty quiet for its power output.
At quarter load its noise level stays around 60 dB which is quite impressive result.
Basically it is as quiet as an idling car engine.
Overall it is a very good refrigerator to run a refrigerator and several other key household appliances.
If you need a reliable generator for emergencies – you should definitely consider the Champion.
WEN 56380i is an inexpensive yet very reliable 3000-watt generator providing enough power to run your refrigerator and freezer.
The generator is built to run as quietly and efficiently as possible. At the 25% load, its noise level is only around 57 decibels when measured from several feet away.
This is more or less the same noise level as two people having a conversation
This generator is very user-friendly and is super easy to run and maintain.
It is an inverter type so your sensitive electronic equipment is totally safe.
It actually comes with 2 USB ports for charging portable electronics.
Fuel economy is another strength of this generator.
At 50% load, you can expect its 2.2-gallon tank to last for around 8.5 hours.
It won’t be a problem to run your refrigerator for the whole night before having to refuel the generator.
Overall WEN 56380i is a very reliable and affordable generator, suitable for most homeowners and RV enthusiasts.
Briggs and Stratton P3000
The Briggs and Stratton P3000 3000 watt inverter generator is a good choice both as a home backup power supply and as a companion for RV and camping trips.
The generator provides enough power output to efficiently run your refrigerator and freezer.
What we like about this generator is its fuel economy.
The total run time at 25% load is around 10 hours which is a really good result when compared to most of the competitors.
You should be able to run your refrigerator for a night without any difficulties.
In case you need more power in the future, you can parallel this generator with another 3000 watt inverter to double your total power output.
That would give you enough power at your disposal to run pretty much all important items in your household.
Can A Generator Damage a Refrigerator?
You should be able to use most portable generators to run your refrigerator without any problems.
It’s true that sensitive electronics like laptop computers or home audio systems demand clean sine wave electricity to operate properly. That’s why inverter generators are the only bulletproof solutions to run these.
Refrigerators are a completely different bunch though. Neither a refrigerator or a freezer classifies as sensitive appliances. You can safely run them using a conventional open frame generator.
Having said that, we still recommend going with the inverter generators such as the Champion 3400 since they are much quieter and lighter than conventional open frame generators.
They would also allow you to eg. run your TV or home audio system during a long and boring blackout.
