Can a 2000 Watt Generator Run a Refrigerator?

Yes! A 2000-watt generator can run your refrigerator. A generator of 2000 watt capacity can easily power up all your house appliances such as; a washing machine, dryer, portable air conditioner, etc. And a refrigerator is no exception. 

When it comes to handling your home appliances during a power break, your 2000 watt generator can keep things running for a few hours.

What Size Generator Do I Need to Run a Refrigerator?

If you are on a tight budget and all you need to power your refrigerator, it depends on how much energy your refrigerator consumes.

For refrigeration to start, the compressor, one of the main components of a refrigerator, takes up a lot of watts for firing up. At an estimation, it can range from 600-900 watts to start it.

For your better understanding, you can think in this way. Whatever watts your compressor consumes to fire itself up your generator has to be 3 to 4 times that number.

For example, if your refrigerator consumes 600 watts to start, purchasing a 1800 watts generator could be enough. So for good measures, multiply the value by 3 or 4 to get the suitable power output from your generator. These values can vary if you have a large or small refrigerator.

I know, that’s a lot of energy at a glance! 

So to be on the safe side, a 2000 watt generator would be more than enough to keep your refrigerator running for hours. It’s because you can never be sure when the electricity will return. 

The bigger the generator, the more expensive it will be, and it will be less movable. So a smart move is needed here!

What Capacity Generator is Required to run a Refrigerator and a Deep Freezer?

If you’re required 2000 watts only for the refrigerator, you will definitely need double of the amount, which is 4000 watts, to run both the refrigerator and a deep freezer. But in reality, you don’t need to do that at all.

If you remember, we decided to use 3 to 4 times the amount of energy required when considering a generator. In that sense, all you need is some additional watts to run both appliances. We are talking about 4000 watts which are ideally enough to run a refrigerator and a deep freezer simultaneously.

But there is another way of using both appliances with just a 2000 watts generator. As they say ” there are no shortcuts in certain cases,” it is true here! You cannot use them simultaneously.

You need to turn off one device and plug in your other appliance. This will require some of your efforts, but look at the bright side; you can use your most necessary appliances with a 2000 watts generator. 

The electrical shutdown can rarely happen since there is a surplus amount of energy available almost everywhere. However, over-preparation is not good sometimes as it will cost you some fortune. So if you’re planning to save some extra bucks, consider buying a 2000 watts.

When buying a generator, it is essential to look at the number of outlets and the correct power outlets. There are two main characteristics of the amount of energy a generator can produce, they are: Running watts and Starting watts.

Running watts: This is the first and foremost and requires small energy when starting an electrical component. It is the amount of energy your device can produce over a long time.

Starting watts: It is the second and requires large energy. It is the maximum amount of energy your device can produce over a while.

Note: A 2000 generator means a machine that can produce 2000 running watts. The starting watts can vary depending on the brand and model of the generator. 

Q2. Can a 2000 watt inverter generator run a fridge?

It is normal to wonder if a fridge can be operated with an inverter generator powered by a solar panel. 

A fridge is an essential component, and yes, it can be powered by an inverter generator. The average starting watts of a fridge are between 800-1200 watts. So 2000 inverter generators would be sufficient for your fridge.

If you want to run a full-size fridge, then look for a generator with a high allowance of watts compared to the starting watts. This should balance the watts and allow your fridge to run without any power shortage.


A 2000 watt generator can easily run a refrigerator, regardless of the fridge type. While using a refrigerator on a generator, it is highly suggested that you keep your refrigerator running for an hour until you switch it off, then turn it on one hour later. This will keep your valuables inside the refrigerator cool yet save energy.
