HOME BACKUP POWER.COMFORT. SECURITY. COME WHAT MAY.
A permanently installed Generac home backup generator protects your home automatically. It runs on natural gas or liquid propane (LP) fuel, and sits outside just like a central air conditioning unit. A home backup generator delivers power directly to your home’s electrical system, backing up your entire home or just the most essential items.

Protect the things that matter during a power outage.
Generac’s Guardian Series 8 kW automatic standby generator provides essential circuit power protection for your home, ensuring necessities such as lights, refrigeration and more remain powered during an outage. This affordable automatic standby generator offers protection for about half the cost of central air conditioning.
Product Details
True Power Technology
Best-in-class power quality with less than 5% total harmonic distortion means clean, smooth operation of your sensitive electronics and appliances.
Easy Installation
When combined with a pre-wired transfer switch, re-engineered connection points, and composite mounting pad that eliminates the need for a poured concrete base (unless specified by local codes), the Guardian Series 8 kW generator is easy to install.
All-Weather Steel Enclosure
Our durable powder-coat finish helps make the sturdy, Galvanneal steel enclosure perfect for all weather conditions. It’s also able to withstand 150 mph winds.
Quick, Quiet Exercise Test
Standby generators require a short run-time periodically, known as exercise, to test and ensure the system is functioning properly and ready for an emergency. The Guardian 8 kW self-test runs for only twelve minutes. Choose your schedule - weekly, bi-weekly or monthly.
Rated for Operation in Areas with Low Natural Gas Pressure
In areas with low natural gas pressure, the Guardian Series 8 kW generator can operate on natural gas pressures of only 3.5” of water column.
