Understanding Generator Sizes
Generators come in various sizes, measured in watts. When selecting a generator to run your refrigerator, it is essential to understand how wattage works. Here are the pivotal points:
What is Watts?
Wattage is a measure of electrical power. A refrigerator requires a certain amount of electricity to start and a different amount to run continuously. Understanding both these values will allow you to choose an appropriate generator.
Surge vs. Running Watts
When discussing wattage, you will often come across two terms: surge watts and running watts.
Surge watts (also known as starting watts) refer to the higher amount of power your refrigerator needs to start up. This amount is typically higher than what the fridge needs while operating.
Running watts are the electricity required to continue running the appliance after it has started.
Knowing both these figures is crucial for selecting a generator that can effectively power your refrigerator.
Determining Your Refrigerator’s Power Requirements
To ensure you buy the right generator, you first need to determine the power requirements of your refrigerator. Most manufacturers list this information on the appliance’s specification label, usually found inside the door or on the back.
Finding the Wattage Ratings
To find your refrigerator’s watts:
1. Check the Power Label: Look for the wattage rating on the fridge’s label. Usually, it will show the running watts and sometimes the starting watts.
2. Calculate if Needed: If the label lists amps instead, you can find wattage by using the formula:
Wattage = Amps x Voltage
In North America, the standard voltage is usually 120 volts.
Example Calculations
For example, if your fridge runs on 6 amps, the calculation would be:
– Running Watts = 6 Amps x 120 Volts = 720 Watts
However, if the starting wattage is 3 times the running wattage, you might need:
– Surge Watts = 720 Watts x 3 = 2160 Watts
This means you would need a generator that can handle at least 2160 watts to start your refrigerator.
Choosing the Right Generator Size
Once you’ve calculated the power needs of your refrigerator, you can start searching for a generator. The generator should meet or exceed the total wattage requirement.
Generator Sizing Recommendations
Many experts recommend having a generator that can provide at least 25% more wattage than your calculated surge requirement. This ensures the generator runs efficiently and has enough power to support other devices if needed.
For example, if you calculate needing 2160 watts:
– Recommended Generator Size = 2160 Watts x 1.25 = 2700 Watts
Therefore, a generator with at least 2700 running watts would be prudent.
Types of Generators
When deciding on a generator, you also need to consider the types available:
- Portable Generators: Great for home use during outages; generally more affordable and flexible.
- Standby Generators: Permanently installed and provides automatic power during an outage; typically more powerful but also more expensive.
Selecting between these options will often depend on your budget, space, and frequency of power outages.
Generator Fuel Types
Generators come in various fuel types, which can affect their efficiency and operational costs. The main types include:
Gasoline Generators
These are commonly available and easy to use. However, they may not be efficient for longer use.
