Losing power can be more than an inconvenience. It can disrupt your home, damage appliances, and create safety risks. The Generac Guardian 8kW is a dependable solution that keeps essential systems running when the grid goes down.
This standby generator restores power within seconds, so you’re never left without electricity during an outage. It runs automatically, giving you a reliable backup without the hassle of a portable unit. This product is a great choice if you want a simple, efficient way to keep your home powered.
What Makes the Generac Guardian 8kW Stand Out?
The Generac Guardian 8kW includes advanced technology and a durable design to ensure reliable backup power. Its automatic transfer switch detects power loss and restores electricity without manual intervention. This seamless transition keeps your home running even when the grid fails.
True Power™ Technology delivers clean, stable electricity, protecting sensitive electronics like computers and medical devices. The generator runs on natural gas or propane, providing flexibility based on fuel availability. Its compact size allows for easy access during installation in residential spaces.
Mobile Link™ Remote Monitoring lets homeowners check the generator status from anywhere using a smartphone or computer. A weather-resistant aluminum enclosure protects against harsh conditions, extending the generator’s lifespan.
These features make the Generac Guardian 8kW a dependable solution for uninterrupted power.
How Much Power Does the Generac Guardian 8kW Provide?
The Generac Guardian 8kW delivers 8,000 watts of backup power, enough to keep your refrigerator, sump pump, lights, and security system running during an outage. It also supports everyday essentials like Wi-Fi, microwaves, and televisions, so you can stay connected and comfortable.
With this generator, food stays cold, the basement stays dry, and you aren’t left in the dark.
Since 8kW won’t power an entire home, many homeowners use load management to distribute power efficiently. This allows high-demand appliances like air conditioners or electric water heaters to cycle on and off instead of running all at once. For homes with moderate power needs, this generator offers a practical and affordable backup solution.
Homes with larger power demands may benefit from a higher-capacity model.
Generac Guardian 8kW Installation & Setup
A licensed electrician or Generac-certified installer should handle the installation to ensure safety and compliance with local codes. The Generac Guardian 8kW connects directly to your home’s electrical panel through an automatic transfer switch, allowing it to start within seconds of a power outage.
The generator must be installed at least five feet from windows and doors to prevent exhaust buildup. To keep it level, it should also be placed on a stable surface, such as concrete or a composite pad. Placing it near your natural gas or propane line makes the fuel connection easier and ensures reliable operation.
Professional installation includes wiring, transfer switch setup, and fuel line connections. After setup, the generator runs automatic self-tests to confirm it is ready when needed.
Before completing the job, a technician will review the installation to ensure everything is working properly.
Fuel Options: Natural Gas vs. Propane
The Generac Guardian 8kW runs on natural gas or propane, so you can choose the fuel that works best for your home. If you have a natural gas line, the generator connects directly to it, providing a steady fuel supply without the need for refills. If natural gas isn’t available, propane works just as well, but you’ll need a storage tank on your property.
Fuel consumption depends on the source. At half load, the generator uses 116 cubic feet of natural gas per hour or 1.16 gallons of propane per hour.
Natural gas is usually cheaper over time, while propane stores well for emergencies. The choice depends on what best accommodates your home’s needs.
How Durable Is the Generac Guardian 8kW?
With proper maintenance, the Generac Guardian 8kW can last 20 to 30 years. It runs a weekly self-test to check for issues, but you’ll need a professional to change the oil, replace filters, and inspect the battery and fuel lines at least once a year.
Most generators handle 3,000 to 5,000 hours of runtime, so limiting use to power outages and routine tests helps extend their lifespan. If a problem arises, a technician can respond quickly to troubleshoot issues and ensure the generator stays in working order.
Generac Guardian 8kW vs. Other Generators
The Generac Guardian 8kW provides reliable backup power, but some homes may need a larger or smaller unit. Generac’s 10kW, 16kW, and 22kW models offer more power for homes with central air conditioning or electric water heaters. If you need less power, a 7.5kW model could be a more cost-effective option.
Compared to other brands, Generac stands out for its automatic operation, remote monitoring, and long-term reliability. If technical issues arise, Generac’s support team may ask for a ray ID when troubleshooting online, helping to quickly diagnose service requests.
