Guardian SeriesTM Generators

Generac’s Guardian® Series provides the automatic backup power you need to protect your home and family during a power outage. With Generac’s Guardian Series, life won’t miss a beat.

How It Works

Connected to the existing LP or natural gas fuel supply, it kicks in within seconds of determining power loss–automatically–and runs for as long as necessary until utility power returns.

8-14 kW Guardian Series generators provide either essential circuit or managed whole house coverage, depending on the transfer switch option:

  • Powered by the Generac OHVI® engine, designed specifically for generators
  • Easily connects to existing LP or natural gas fuel supply; quickly converts in the field
  • Composite mounting pad included, making installation easier in places where a concrete pad is not required
  • Galvanneal steel enclosure features RhinoCoat™ finish for superior weather protection; withstands winds of up to 150 mph
  • TruePower™ technology provides clean, smooth operation of sensitive electronics and appliances
  • Choose the pre-wired EZ Switch™ for essential circuit coverage or the Nexus Smart Switch™ with load shedding capabilities for managed whole-house coverage

17 and 20 kW Guardian Series generators offer additional, premium features:

  • Aluminum enclosure provides excellent protection in salt air coastal areas (optional on 17kW)
  • Quiet-Test™ weekly self-test mode runs at a lower RPM and is quieter than other brands, consumes less fuel, and produces fewer emissions
  • External GFCI outlet
