QuietSource Series 48kw


Product Description

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.
Super quiet, super efficient, patented Quiet-Test mode for a weekly test mode that’s quieter than other brands, consumes less fuel and helps make your Generac generator the most environmentally friendly on the market.
Standard aluminum, all-weather enclosure provides the ultimate protection from the elements. Aluminum’s natural corrosion resistance prolongs the life of your generator and is recommended for salt-air, coastal locations.

Generac has created a controller for liquid-cooled models with an improved user interface for easier monitoring and management of the generator functions.

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.
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.
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.
