When it comes to ensuring your home is always powered, a built-in home generator is an excellent investment. Unlike portable generators, built-in generators are permanently installed and automatically kick in during a power outage. This article will guide you through everything you need to know about the best built-in home generators, including how they work, their benefits, and what to consider when choosing one.
What is a Built-In Home Generator?
A built-in home generator, also known as a standby generator, is a device that provides backup power to your home during an outage. It is permanently installed outside your home and connected directly to your electrical system. When the main power supply fails, the generator automatically starts and supplies electricity to your home until the main power is restored.
How Does a Built-In Home Generator Work?
Built-in home generators are connected to your home’s electrical panel and are powered by an external fuel source, usually natural gas or propane. Here’s a step-by-step breakdown of how they work:
Power Failure Detection: The generator is equipped with an automatic transfer switch (ATS) that constantly monitors the power supply from the utility company.
Automatic Start: When the ATS detects a power outage, it sends a signal to the generator to start.
Power Generation: The generator starts and begins producing electricity, which is then fed into your home’s electrical system.
Power Restoration: Once the main power supply is restored, the ATS switches the power source back to the utility company and signals the generator to shut down.
Benefits of a Built-In Home Generator
Automatic Operation
One of the biggest advantages of a built-in home generator is its automatic operation. You don’t need to be home to start it; the generator will kick in automatically during a power outage, ensuring your home remains powered without any manual intervention.
Continuous Power Supply
Built-in generators can power your entire home, including essential appliances like refrigerators, heating systems, and medical equipment. This is particularly important during prolonged outages, ensuring your family’s comfort and safety.
Increased Home Value
Installing a built-in home generator can increase the value of your property. Potential buyers often view a standby generator as a valuable addition, especially in areas prone to frequent power outages.
Fuel Efficiency
Built-in generators are designed to be fuel-efficient. They run on natural gas or propane, which are generally more cost-effective and environmentally friendly compared to gasoline or diesel.
Low Maintenance
Once installed, built-in generators require minimal maintenance. Most models come with self-diagnostic features that alert you to any issues, making it easier to keep the generator in good working condition.
Key Features to Consider When Choosing a Built-In Home Generator
Power Output
The power output of a generator is measured in kilowatts (kW). To determine the right size for your home, calculate the total wattage of all the appliances and systems you want to power during an outage. A professional electrician can help you with this calculation.
Fuel Type
Built-in generators typically run on natural gas or propane. Natural gas is often preferred because it is supplied through a utility line, ensuring a continuous fuel supply. Propane, on the other hand, is stored in tanks and may require refilling.
Noise Level
Generators can be noisy, but modern built-in models are designed to operate quietly. Look for generators with noise levels below 70 decibels (dB) for a more peaceful home environment.
Transfer Switch
The automatic transfer switch (ATS) is a critical component of a built-in generator. It ensures a seamless transition between the main power supply and the generator. Make sure the generator you choose comes with a reliable ATS.
Warranty and Support
A good warranty is essential for protecting your investment. Look for generators with at least a 5-year warranty. Additionally, consider the availability of local service and support in case you need repairs or maintenance.
Brand Reputation
Choose a generator from a reputable brand with a history of reliability and customer satisfaction. Some of the top brands in the market include Generac, Kohler, and Cummins.

Installation and Maintenance Tips
Professional Installation
Built-in home generators require professional installation. A licensed electrician will ensure the generator is correctly connected to your home’s electrical system and fuel supply. Improper installation can lead to safety hazards and void the warranty.
Regular Maintenance
To keep your generator in optimal condition, perform regular maintenance tasks such as checking the oil level, inspecting the air filter, and testing the battery. Most generators come with a maintenance schedule that you should follow.
Fuel Supply Management
If your generator runs on propane, ensure you have an adequate supply of fuel. For natural gas generators, check the gas line for leaks or blockages. A well-maintained fuel supply is crucial for the generator’s performance.
Test Runs
Conduct regular test runs to ensure the generator is functioning correctly. Most generators have a test mode that allows you to simulate a power outage. This helps identify any issues before an actual outage occurs.
Conclusion
A built-in home generator is a reliable and efficient solution for ensuring your home remains powered during an outage. By understanding how these generators work, their benefits, and what to look for when choosing one, you can make an informed decision that meets your home’s needs. Whether you opt for a Generac, Kohler, or Cummins model, investing in a built-in generator will provide peace of mind and protect your home from the inconvenience of power outages.
Remember to consult with a professional electrician for installation and maintenance to ensure your generator operates safely and efficiently for years to come. With the right built-in home generator, you can rest easy knowing your home will always have power, no matter what.
