Residential Generac Home Standby Generators

Reliable Whole-House Backup Power for Your Home

Power outages don’t just turn the lights off, they interrupt heating, air conditioning, refrigeration, internet access, cooking appliances and home safety systems. A Generac home standby generator automatically restores power to your house within seconds of losing utility power, keeping your home comfortable and operational.

TriStar Electric Inc., a Generac Elite Dealer serving Maryland, Washington DC, and Northern Virginia, installs residential standby generator systems designed specifically for homeowners who want dependable backup power without manual setup or refueling.

What Is a Residential Home Standby Generator?

A residential standby generator is a permanently installed backup power system connected directly to your home’s electrical service and fuel supply (natural gas or propane).

When an outage occurs:

1. The automatic transfer switch detects the loss of utility power
2. The generator starts automatically
3. Your home’s electrical circuits are restored in seconds

When power returns, the generator safely shuts off and resets itself for the next outage.

No extension cords.
No portable generators.
No going outside during a storm.

It’s completely self-contained and automatic.

Natural Gas vs Propane Residential Generators

Residential standby generators typically run on one of two fuels.

Natural Gas

• Continuous fuel supply
• No refilling required
• Ideal for homes with natural gas utility service

Propane

• Reliable alternative where gas isn’t available
• Long shelf life
• Suitable for rural properties
• Burns cleaner and hotter than natural gas
• More efficient and more power from your generator
• No risk of natural gas utility interruption

TriStar Electric helps homeowners choose the fuel source that offers the best reliability for their location.

How the Generator Operates During an Outage

A standby generator system includes two main components:

Generator Unit which produces electricity
Automatic Transfer Switch which safely transfers power between utility and generator

The transfer switch prevents back feeding and protects utility workers while restoring power to the home.

The process is fully automatic and typically restores power within seconds.

Monitoring and Maintenance

Generac residential generators perform a weekly exercise cycle to keep internal components lubricated and ready.

Homeowners can also monitor system status remotely using mobile monitoring features, allowing them to verify the generator is ready even while away from home. Dealer monitoring allows for TriStar Electric to monitor your generator as well, we check our customers generators daily and often know when there is an issue before they do.

Routine maintenance keeps the system prepared for long-term reliability.

Why Professional Installation Matters

A standby generator must be correctly sized, wired, and fueled to function reliably. Improper installations often work during testing but fail during actual outages.

As a Generac Elite Dealer, TriStar Electric provides:

• Proper electrical load sizing
• Code compliant installation
• Manufacturer approved wiring methods
• Startup testing and verification
• Long term service support

Our focus is installing systems that operate correctly years later, not just on installation day.
