Generac Power Systems EXTWRTYLCSM Details and Specifications


Generac makes it easy to configure a standby backup power system for your home or business needs. The 48kW liquid-cooled generator is capable of providing standby backup protection for large homes and commercial applications, designed specifically for high demand power generation needs.
Low speed, automotive style liquid-cooled engine runs at only 1800 rpm during a power outage for a substantially quieter generator, greater fuel efficiency, and longer engine and alternator life.

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.

Generac's Nexus Controller is the most comprehensive available. The dual line, tri-lingual LCD display allows for easy monitoring and management of generator functions.

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.

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.

Clean burning, continuous fuel choice of LP or natural gas.

Neutral styling, color and small footprint fits unobtrusively into landscaping.

Features of the Nexus Controller:
• LCD Display
• Remote Maintenance LED's
• Time & Date
• Alarm Log
• Run Log
• Set Exercise via Display
• Engine Hour Display
• RPM Display & Sensor Loss Alarm
• Frequency
• Battery Voltage Display
• Trilingual Display
• Underspeed/fail to Transfer Alarm
