Power outages can be frustrating, inconvenient, and even dangerous, especially if they last for an extended period. Having a backup generator can provide peace of mind and ensure that essential appliances and systems in your home continue to function during these outages. But what size generator do you need for your house? Let’s explore this question in-depth to help you make an informed decision.
The Importance of Choosing the Right Generator Size
Choosing the right generator size is crucial to ensure that it can handle the electrical load of your home during power outages. An undersized generator may not be able to power all the necessary appliances and could potentially cause damage to the generator or the connected devices. On the other hand, an oversized generator may lead to unnecessary expenses in terms of fuel consumption and upfront costs.
Factors to Consider When Determining Generator Size
Several factors come into play when determining the appropriate generator size for your home during power outages. Let’s take a closer look at these factors:
1. Electrical Loads and Appliances
The first step in determining the generator size is to assess the electrical loads and appliances in your home. Make a list of all the appliances that you consider essential during power outages, such as refrigerators, sump pumps, heating systems, lighting, and communication devices. Note down their running and starting wattage requirements. This information is usually available on the appliance’s label or in the user manual.
2. Continuous Electric Currents
To accurately determine the wattage rating of the generator, you need to measure the continuous electric currents on both lines L1 and L2. Choose the larger current from the two lines as the starting point for calculating the generator size. This ensures that the generator can handle the combined load of all the appliances connected to both lines.
3. Surge Capacities
Some appliances, particularly large motor-driven equipment like central air conditioning units, require higher starting wattage known as surge capacities. Surge capacities account for the initial power spike needed to start these devices. It’s important to consider these surge capacities when calculating the generator size to ensure it can handle the temporary increase in electrical load.
