Features & Benefits:

Provides essential circuit power protection for your home, ensuring the necessities remain powered during an outage. This affordable automatic standby generator offers protection for about 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.

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.

Tool-less Fuel Conversion

Switch between natural gas and LP fuel in the field in a few seconds, without the need for any tools.

Rated for Operation in Areas with Low Natural Gas Pressure

In areas with low natural gas pressure, the Guardian Series 20 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 Steel Enclosure

Power Armor finish helps make the sturdy, Galvanneal steel enclosure perfect for all weather confitions. It’s also able to withstand 150 mph winds.

Quiet-Test™ Mode

Thanks to Quiet-Test, your Guardian Series home standby generator runs its weekly self-test at a lower RPM. It’s quieter than other brands, and consumes less fuel. Available on 17kW and 20kW Guardian Series only.

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 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.

Included - Generac's Pre-Wired 10 Circuit Transfer Switch

By sizing your generator system according to your needs instead of your home’s square footage, you won’t overspend or be surprised by inadequate coverage. Many homeowners choose to cover only their essential circuits during a power outage. Pair a smaller generator with Generac's pre-wired switch for a simple, remarkably economical system that will keep your basics powered during an emergency.
