| Side-by-Side Refrigerators | 200-800 W | 600-1500 W |
| Refrigerators with Freezers | 200-900 W | 600-1800 W |
These ranges provide a helpful guide, but it’s always best to check the manufacturer’s label on your specific refrigerator for precise wattage requirements.
Determining the Right Generator Size
Selecting the appropriate generator involves more than just knowing the watts required for the refrigerator. Below we will discuss how to effectively determine the size of the generator you will need.
Calculate Your Total Wattage Needs
To choose the right generator, you must ensure it meets your total wattage needs. This means considering all appliances you want to run with the generator, not just the refrigerator.
Identify Running and Starting Watts: As mentioned previously, you need both running and starting wattage for your refrigerator.
Add Other Appliances: If you plan to power additional appliances, account for their wattage as well. This could include lights, microwaves, coffee makers, or additional cooling devices.
Calculate the Total: Add the starting wattages of all items you wish to run simultaneously. Keeping in mind that some appliances, like lights, may not require many watts, while larger units will.
Example Calculation
Suppose you have the following appliances:
- Refrigerator: 700 running watts, 1200 starting watts
- A few lights: 300 running watts (no significant starting watts)
- Microwave: 1000 running watts, 2000 starting watts
Total Starting Watts Calculation:
– Refrigerator: 1200 W
– Lights: 300 W
– Microwave: 2000 W
Total Starting Watts = 1200 + 300 + 2000 = 3500 Watts
In this scenario, a generator with a starting capacity of at least 3500 watts would be required.
