Rugged Encasing Stands Up to Harsh Weather
Ruggedly enclosed in tough steel and protected by Generac's proprietary RhinoCoat system--a unique process that binds the paint to the metal surface for a long-lasting, durable finish--this generator protects against debris and holds up against the elements without developing an unsightly appearance. Plus, all components are easily accessible for routine maintenance.
Quiet-Test Feature Means Whisper-Quiet Operation
Specially designed with Generac's patented Quiet-Test technology, this generator is ideal for environments requiring super quiet performance. The Quiet-Test mode kicks on for an ultra-quiet, neighborhood-friendly self-test that's as hushed as a car in an idle state.

From the Manufacturer
Just because your home requires more power doesn't mean you have to pay a whole lot more. Generac Power Systems has taken all of the leading-edge technologies from our industrial product line and applied them to our GUARDIAN Elite liquid-cooled products. Models range from 25-45 kW and cost thousands of dollars less than competitors' units. They also feature automotive style, liquid-cooled engines and our exclusive Whisper-Test feature. You won't find more affordable products with this kind of power. Our industrial grade automotive engines provide unmatched power and long life. If an engine is designed for an over-the-road truck to run hundreds of thousands of miles, just think how long a generator that never leaves your home will last. GUARDIAN's exclusive Whisper-Test low speed exercise feature makes our GUARDIAN Elite systems the quietest liquid-cooled generators on the market. Whisper-Test reduces noise by 50% during the generator's weekly automatic self-test cycle allowing for near silent operation that satisfies all known sound ordinances.
