For example, let’s say your refrigerator has an amp rating of 5 amps and a voltage of 120 volts. To find the wattage, simply multiply the amps by the voltage:
Wattage = Amps x Voltage
Wattage = 5 amps x 120 volts
Wattage = 600 watts
Step 2: Account for the Starting Surge
When starting, refrigerators typically require more power due to the surge of energy needed by the compressor. This surge can be double or triple the fridge’s wattage. To account for the starting surge, multiply the fridge’s wattage by 2 or 3, depending on how conservative you want to be. In our example, we’ll multiply by 2:
Starting Surge Wattage = Refrigerator Wattage x Starting Surge Multiplier
Starting Surge Wattage = 600 watts x 2
Starting Surge Wattage = 1200 watts
Keep in mind that some refrigerators may require a higher starting surge, so it’s always a good idea to check the manufacturer’s recommendations.
Step 3: Consider Other Appliances
If you plan on running other appliances or devices alongside the refrigerator, make sure to include their wattage as well. Add up the wattage of all the appliances and devices to get the total power requirement.
Step 4: Choose the Generator
Once you have determined the total wattage needed, choose a generator that can handle at least that amount. It’s generally recommended to get a generator with a capacity that is 20-25% higher than the total wattage required. This provides a buffer and ensures the generator won’t be running at its maximum capacity.
Keep in mind that running a refrigerator on a generator for an extended period of time can consume a significant amount of fuel, so consider the fuel efficiency and capacity of the generator as well.
| Appliance/Device | Wattage |
|---|---|
| Refrigerator | 600 watts (starting surge: 1200 watts) |
