Provides essential circuit power protection for your home, ensuring the necessities remain powered during an outage. The most affordable automatic standby generator on the market offers protection for half the cost of central air conditioning.

  • Generac OHVI® Engine: Your Guardian Series generator might have to get you through days—or weeks—without utility power. Its OHVI® engine, specifically designed for generator use, provides the reliability to power through the most severe outages.
  • Evolution™ Controller: The next generation of intuitive controllers featuring a multilingual, two-line LCD text display with color-coded, backlit buttons.
  • Certified for 18" Installation to the Home: Third-party certified to NFPA standards to be installed as close as 18” from the home’s exterior wall, provided it is located away from doors, windows, and fresh-air intakes, and unless otherwise directed by local codes.
  • Easy Installation: With an intelligent 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.
  • 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—significantly lower than published numbers for competitive standby generator systems.
  • All-Weather Aluminum Enclosure: Our durable powder-coat finish helps make the sturdy, all-weather aluminum enclosure corrosion resistant, making it ideal for coastal, salt-air climates. It’s also able to withstand 150 mph winds.
  • Tool-less Fuel Conversion: Switch between natural gas and LP fuel in the field in a few seconds, without the need for any tools.
  • 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.
  • Mobile Link™ Compatible: Take advantage of Generac’s Mobile Link cellular remote monitoring system and check on your generator’s status using your computer, tablet or smartphone, even when you are away. Sold separately.
  • 24/7/365 Customer Support: Power outages don’t always occur during normal working hours. That’s why Generac’s customer care call center—right here in Wisconsin—provides support any time of day or night, all year long. Generac is standing by 24/7, every minute of every day, to answer your questions.

Note: Fuel pipe must be sized for full load. Required fuel pressure to generator fuel inlet at all load ranges - 3.5-7" water column (7-13 mm mercury) for natural gas, 10-12" water column (19-22 mm mercury) for LP gas. Outputs are based upon values @ 1000 Btu per cubic feet with NG and 2500 Btu per cubic feet with LP; @ 37.26 Megajoules per cubic meter with NG and 93.15 Megajoules per cubic meter with LP **Sound levels are taken from the front of the generator. Sound levels taken from other sides of the generator may be higher depending on installation parameters. Rating definitions - Standby: Applicable for supplying emergency power for the duration of the utility power outage. No overload capability is available for this rating. (All ratings in accordance with BS5514, ISO3046, DIN6271 and AS/NZS CISPR 12:2009). * Maximum wattage and current are subject to and limited by such factors as fuel Btu content, ambient temperature, altitude, engine power and condition, etc. Maximum power decreases about 3.5 percent for each 1,000 (304.8 meters) feet above sea level; and also will decrease about 1 percent for each 6 °C (10 °F) above 16 °C (60 °F).
