What Is a Whole Home Generator?
A whole home generator, or home standby generator, automatically delivers backup power to your entire house during an outage. Permanently installed, it connects to natural gas or a propane tank for a reliable fuel supply. Unlike a portable generator, a standby generator starts automatically within seconds of a power loss, keeping your lights, refrigerator, sump pump, and air conditioner running. Most home generators range from 5,000–20,000 watts, and selecting the right size generator ensures safe operation for your home’s electrical load. A transfer switch connects the system to your circuit panel, safely managing circuits without extension cords. This automatic, reliable backup delivers lasting comfort and protection for your family during any power outage.

FAQs About Home Generators
-
A home generator (also called a home standby generator) connects to your home’s electrical panel through a transfer switch. When the utility power goes out, the generator automatically starts, supplying backup power within seconds. Once power is restored, the system shuts down and returns to standby mode — no manual setup required.
-
The cost of a home generator installation depends on the system’s size, fuel type (natural gas or propane), and your home’s electrical load. Most whole home generators cost between $6,000 and $15,000, including installation and permits. Insight Energy provides free assessments to help you determine the best home backup generator for your needs and budget.
-
The right size generator depends on the number of appliances and systems you want to power, like your refrigerator, sump pump, HVAC system, or well pump. Smaller homes may only need a 7,500‑watt generator, while larger homes often require 20,000 watts or more. Our team calculates your home’s electrical load to ensure safe, efficient operation.
-
A standby generator connects to your circuit panel through an automatic transfer switch, which safely transfers power between your generator and the utility grid. This setup prevents back‑feeding and ensures your generator powers only your home, not nearby lines. Always have a professional handle your home generator installation for safety and compliance with local codes.
-
The operating cost of a whole house generator depends on fuel type and load. On average, natural gas generators cost $2–$3 per hour to run, while propane generators average $3–$5 per hour. Because they start automatically and run efficiently, they only use fuel when power is lost, saving you money over time.
-
Yes. A properly sized whole home generator can power your entire house, including essential appliances, heating and cooling systems, and even high‑demand equipment like hot tubs or pool pumps. Insight Energy’s team designs each system to match your home’s electrical load for seamless, reliable backup power.
-
With proper maintenance and professional installation, most home standby generators last 15–20 years or 3,000–5,000 operating hours. Regular oil changes, filter replacements, and annual inspections help maintain performance, efficiency, and warranty coverage.
-
When choosing a home generator, consider your power requirements, fuel access (natural gas or propane), and where the generator will be installed. Insight Energy provides expert guidance on size, placement, and installation cost to ensure your system delivers reliable backup power for years to come.
