How a Whole-Home Standby Generator Works
Unlike portable generators, which are manually operated for short-term use, whole-home generators are permanently installed and can start automatically during an outage to provide backup power to the household loads included in the system design. They’re designed for reliable, long-term protection and require little effort from you once set up.
A home standby generator runs on propane, diesel, or natural gas and powers everything from your HVAC to your refrigerator, so you’re never left unprepared during an outage. It runs automatically, operates efficiently, and requires very little maintenance. This makes it a safer, more convenient solution for long-term protection.
What Size Generator Does Your Home Need?
Proper sizing gets you uninterrupted power for extended outages. These are the factors that influence sizing:
- Appliances: Add up all the appliances you need during a blackout. For example, a refrigerator may use 600–800 watts, while an electric oven can require around 5,000 watts.
- Heating and Cooling Equipment: HVAC systems can significantly increase demand. An electric furnace requires at least 5,000 watts.
- Major Home Systems: Don’t forget essential systems like sump pumps.
- Starting Wattage: Appliances with motors need extra power to start. A general estimate is three times the running wattage for startup.
- How Much Runs at Once: Account for the combined wattage of the appliances and systems you expect to operate simultaneously.
- Capacity Buffer: Your total power needs should use no more than about 90% of the generator’s capacity, leaving room for startup demands and power fluctuations.
As a general rule of thumb, you need at least 12,000 watts to keep a small home running.
The Installation Process, Step by Step
After we determine the right size generator, it’s time to install your home backup. Here is the installation process.
- Choose a Safe Installation Location: The generator is positioned according to manufacturer requirements and local regulations, including required clearances from the home.
- Secure Permits and Prepare the Site: We obtain necessary permits and prepare the installation area for the generator and its connections.
- Connect the Fuel Supply: Connect the generator to the home’s fuel lines so it has a reliable fuel source during an outage.
- Complete the Electrical Connections: An electrician wires the generator into the home’s electrical system and installs the equipment needed to safely transfer continuous power during an outage.
- Test the Generator: The completed system is tested to verify that the generator starts and operates as intended.
Your technician explains how the generator works, what to expect during an outage, and how to operate and maintain the system.

FAQs
Can I install a whole home generator myself?
Whole-home generator installation is best handled by professionals qualified to perform the required electrical and fuel work. Installation typically involves permits, electrical wiring, a transfer switch, natural gas or propane connections, and compliance with local codes. Professional installation helps ensure the generator operates safely and correctly.
How do I know what size whole-home generator I need?
Generator size depends on which household systems you want to power, their running and startup loads, and how much equipment may operate simultaneously. A professional load assessment is the best way to determine appropriate capacity.
What are the disadvantages of whole house generators?
Whole-house generators have few disadvantages, but upfront cost and installation requirements are important considerations. Standby generators also require adequate outdoor space and must meet local placement and clearance requirements.
Are standby generators worth the money?
Standby generators can be worth the money for homeowners who experience power outages and need to keep essential systems running. A standby generator can automatically provide backup power for equipment such as refrigerators, HVAC systems, sump pumps, medical equipment, and lighting. Whether one is worth the investment depends on your backup power needs, outage risk, and budget.
Do I need to refuel my whole home generator?
You may need to refuel your whole-home generator, or it may be connected to a natural gas line. Propane-powered generators generally use a storage tank that eventually needs refilling. How long a propane supply lasts depends on tank size, generator load, and outage length.
