What size generator to run fridge and freezer? (Important: Starting Watts)

We need refrigerators and freezers even when there is a power failure. In such an emergency, we need a generator to run our fridge. The important question for everyone who uses a generator to run a fridge is:

What size generator do I need to run a refrigerator and freezer?

Usually, it’s pretty easy to figure out how big a generator you need to power electrical equipment. Just check the wattage, and get a generator that produces the same running wattage. When a generator is sized enough for a refrigerator and freezer, things get more complicated because the fridge has to be turned on every few minutes. that means we have to account for Beginning wattage,

Here’s the deal:

The peak wattage for a refrigerator and freezer can be 3-4 times higher than the running wattage. This means that even though your refrigerator and freezer run on 700W, you may not get a wattage generator running 700W. Yes, such a generator can run the fridge, but it will not be able to start it. You will have a very small generator and a flooded fridge.

Here’s how to solve it without some guesswork ‘Can a 1,000 watt generator run a refrigerator’,

You need to find both specifications for your electrical appliance:

  1. running watts From refrigerator and freezer. can be anywhere 50W to 1,500W . till,
  2. start wats From refrigerator and freezer. can be anywhere 200W to 6,000W . till,

Based on this, you will know what size generator you need to run your fridge in case of a power outage.

To help you out, we’ve put together a list of refrigerator and freezer starting and running wattages. This includes all types of refrigerators including French door refrigerators, side-by-side refrigerators, top freezer refrigerators, bottom freezer refrigerators, mini-fridges and even freezerless refrigerators (fridge without freezer).

Example: A standard refrigerator makes 700W and has an additional 2,200W starting wattage (this means total starting wattage is 2,900W). Will a 2,000W generator drive this fridge? this will not happen. But a 3,000W generator will.

Let’s see how many watts are needed by different sizes of refrigerators and freezers. Based on this, we will be able to select the right size generator; We recommend even some of the most common fridge wattages.

Refrigerator/Freezer Watts On And On

Fridge’s running wattage ranges from 50W to 1,500W. More importantly, the starting wattages of refrigerators and freezers range from 200W to 6,000W.

Here’s a complete list of fridge wattages. Check how many running watts and peak watts are in your fridge:

Fridge and Freezer: Running Watts: Starting Watts:
small mini fridge 50 watts 200 watts
standard mini fridge 75 watts 300 watts
big mini fridge 100 watts 400 watts
Small Energy Star Fridge 132 watts 528 watts
Standard Energy Star Fridge 192 watts 768 watts
Big Energy Star Fridge 250 watts 1,000 watts
mini fridge 400 watts 1,200 watts
standard fridge 700 watts 2,900 Watts
Big Side-by-Side Fridge 1,000 watts 4,000 watts
biggest fridge 1,500 watts 6,000 watts

As you can see, a lot of electrical power is required to run the refrigerator and freezer. More importantly, they require a large amount of start-up power just to start up. If you have a rotary compressor refrigerator, it will constantly turn on and off every few minutes.

To find out how much running wattage your refrigerator and freezer have, just check the specification label. It is usually located on the back of the fridge; You have to shake it a little to check.

How to find out how much start-up wattage your fridge needs?

Very few fridges have start-up watts specified on the label. In most cases, you’ll have to ‘best guess’ how much starting power they need.

The rule of thumb for refrigerator generator size is to multiply the running watts by 4 to get the starting watts. Here’s how you calculate it:

Starting Watts = 4 × Running Watts

This means that 1,000W running watts will have about 4,000W starting watts. This means that you would need at least a 4,000W generator to run such refrigerators and freezers without any problems during power outages.

Let’s take a look at which generators you can use to power your fridge:

What size generator do I need to run a refrigerator and freezer?

When choosing the right size generator for a refrigerator and freezer, you can skip checking the running wattage. What really matters is the starting wattage of the generator.

For example why: A 2,000W generator will produce 2,000W starting watts and 1,600 running watts. A refrigerator that requires a starting wattage of 2,000W will run at around 500W running watts.

Running watts are never a hindrance; Initial watts.

Using this logic, here are the ranges of how big a generator you need for different refrigerators/freezers:

  • 1,000W generator For everyone mini fridge and most environmentally friendly Energy Star-rated refrigerators and freezers.
  • 3,000W generator For All standard refrigerators and freezers, 3,000W generator most common A generator is used to run the refrigerator.
  • 5,000W+ generator to bring power to all Very large and spacious refrigerators and freezers, However, not many people have such a large fridge.

In more than 95% of cases, you are seeing 1,000W or 3,000W generator, Of course, the best thing to do is to buy the quietest inverter generator. Honda, for example, produces the best overall generators.

Generator Recommendations for Mini Fridge and Energy-Star Fridge (1,000W)

If you need a recommendation Best 1,000W Generator For small refrigerators and freezers there is the Honda EU1000I. It’s quiet, multi-purpose, and has an inverter motor.

Honda makes the best generators but they are definitely of a higher price range. For a cheap 1,000W generator to power refrigerators and freezers, you can opt for a lesser quality thing like a PowerSmart 1,000W generator.

Generator Recommendations for Standard Refrigerator and Freezer (3,000W)

Most homes will need a 3,000W generator to run their refrigerators and freezers.

Top of the Line 3,000W Generator for Refrigerator and Freezer The quietest generator on the market is the Honda EU3000IS. This is one of the most popular generators overall and the best choice for providing the starting watts needed to start and run refrigerators and freezers.

If you are looking for low quality and cheap 3,000W generator, the Craftsman C0010030 3000i is another option.

This is the 101st way to get the generator sized enough for the refrigerator and freezer.
