Features
What's built in.
Generac Nexus Controller
Generac’s Nexus™ Controller is the most comprehensive available. The dual line, tri-lingual LCD display in English, Spanish, and French allows for easy monitoring and management of generator functions.
Powerful low-speed, liquid cooled engine
Powerful low-speed, liquid cooled engine is engineered to run at only 1800 rpm for a substantially quieter generator, consuming less fuel and giving both the engine and alternator a longer life. Packs more power into a smaller footprint than air-cooled models.
Standard aluminum, all-weather enclosure
Standard aluminum, all-weather enclosure provides the ultimate protection from the elements. Aluminum’s corrosion resistance prolongs the life of your generator and is recommended for salt-air, coastal locations.
Quiet-Test™ Mode
Quiet-Test™ mode for a weekly self-test that runs quieter than other brands. Patented, programmable feature validates proper operation. Runs at lower RPM for reduced noise, less fuel consumption, and fewer emissions.
Neutral styling, color and small footprint
Neutral styling, color and small footprint fits unobtrusively into landscaping.
Choice of LP or Natural Gas
Clean burning, continuous fuel choice of LP or natural gas.
