Calculating Your Refrigerator’s Wattage Needs
To choose the correct generator wattage, start by determining the wattage requirements of your refrigerator.
Finding the Specifications
Most refrigerators will have a label that tells you its wattage requirements. This label is often found inside the unit or on the back. If you can’t find it, consider the following:
- Older Models: These typically consume more power, around 600–800 running watts.
- Modern Energy-Efficient Models: These can be as low as 100–400 running watts.
Below is a general guideline for refrigerator wattage:
| Type of Refrigerator | Average Running Watts | Average Starting Watts |
|---|---|---|
| Compact Refrigerator | 50-100 Watts | 150-200 Watts |
| Standard Refrigerator | 100-400 Watts | 600-800 Watts |
| High-Efficiency Refrigerator | 200-300 Watts | 400-600 Watts |
Calculating Your Total Wattage Requirement
Once you have the running and starting wattages, add an additional 20% to account for any fluctuations in power usage. Here’s the formula:
Total Watts = Starting Watts + (Running Watts x 1.2)
For example:
– Starting watts: 800
– Running watts: 200
The calculated wattage will be:
Total Watts = 800 + (200 x 1.2) = 800 + 240 = 1040 Watts
Thus, a generator with at least 1040 watts capacity would be required to safely power the refrigerator without issues.
