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 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.

What is the difference between an automatic air-cooled generator and an automatic liquid-cooled generator? The engines! Air-cooled generators come with engines that use fans to force air across the engine for cooling, while liquid-cooled generators use enclosed radiator systems for cooling, similar to an automobile. Generally, liquid-cooled engines are used on larger kW generators due to the larger engines required for the higher power output. Generac Liquid Cooled Generators start at 22 kw. They offer Quieter operation and longer service life.

NEXUS CONTROLLER FEATURES   The new Nexus controller for liquid-cooled generators (22-150 kW) not only includes upgraded features available in the original controller, but also includes several new features, making it the most comprehensive air-cooled controller available. External common fault alarm Allows for a connection to drive a common alarm if any shutdown for the generator occurs (i.e., security system, home automation integration) Wiring error Gives indication if transfer switch is connected incorrectly without allowing board damage Battery sentinel Monitors the battery to indicate that the battery is going to fail or if it has failed Generator high voltage shutdown Shuts down generator at preset levels to avoid high voltage damage to appliances Generator low voltage shutdown Shuts down generator at preset levels when voltage dips too low Internal fault shutdown Shuts down generator in event of controller failure Master Nexus Controller includes voltage regulator, battery charger and engine controller +/-1% voltage regulation, smart charging battery system where output voltage is dependent upon ambient temperature and only charges the system when needed now available on all models:   LCD display and keyboard Remote maintenance LEDs Time & date Alarm log Run log Set exercise via display Engine hour display RPM display & sensor loss alarm Frequency Battery voltage, Underspeed/fail to transfer alarm, High engine temperature alarm, Low oil, display Trilingual display LCD/LED display and keypad Improved user interface. Provides accurate, real time readings to both owner and service contractor. Remote maintenance LED Helps to protect equipment with visual reminder of required maintenance. Communicates directly with owner based on usage rather than relying solely on a service contractor and a scheduled maintenance cycle. Wireless ready Provides expandable interface capabilities consistent with trends in future communication capabilities. Time & date Assures speed and accuracy in maintaining key aspects of user interface such as scheduled maintenance and exercise cycles. Alarm log Provides accurate means of tracking both scheduled and unscheduled run time events that could effect maintenance, service and product life. Run log Maintains readings of run time in exercise cycles and use related to outages for improved accuracy in scheduling maintenance and determining product life. Set exercise via display Simple, easy-to-use control set-up provides the owner the option of at will setting/ changing exercise rather than total reliance of Service Contractor. Engine hours display Provides accurate run times to help assure proper maintenance intervals are maintained. RPM and frequency displays Hastens service diagnosis and provides immediate operation data at installation. Hours under load Provides insight into the consistency/quality of grid power input essential for adjusting maintenance intervals to actual hours rather than a time period. Low fuel pressure Helps to assure correct installation of fuel source at start-up TECHNICAL DOCUMENTATION 0H7319 MANUAL 4.2L C2 48KW EPA CERTFD COVER194 COVER 4.2L 48KW EPA CERTIFIED CONTENT049 TABLE OF CONTENTS NEXUS 4.2L SAFETY004 SAFETY GENERIC IDENTY005 IDENTIFICATION, CPL MODELS EQUIP001 EQUIPMENT DESC CPL SERIES ENGPROT003 ENGINE PROTECT FEATURES NEXUS FUELSYS001 FUEL SYSTEM CPL SERIES GENSPEC086 GENSET SPEC 4.2L 48KW CERT ACCONN007 AC CONNECTION 1/3PH 6/12 LEAD CNTRLNEXUS001 CONTROL PANEL INTERFACE NEXUS OPER001 OPERATION, CPL SERIES MAINT028 MAINTENANCE 4.2L CPL SRVSCHD004 SERVICE SCHD QT SERIES NEXUS TRBLSHT003 TROUBLESHOOTING CPL NEXUS EMSNWRNTY001 EPA WARRANTY EMSN STATEMENT NOTES NOTES PAGE CPL 0H7326 EV CONBOX C2 CPL 0G5899 EV CPL ALTERNATOR 0G5965 EV MTG BASE 4.2L G3 0G5972 EV BATT ACSRY 4.2L G3 W/O BATT 0H7324 EV ENGCOMPRT 4.2L G3 48KW 0F9809 EV AIR CLEANER 0H3077 EV COOLING SYSTEM 4.2L G3 0H7582 EV FUEL SYSTEM 4.2L 48KW 0G5866 EV MUFFLER EXH 4.2L G3 CPL 0H0004 EV ENCLOSURE C2 0H0171 INSTALL 4.2L G3 48KW 0H6342 WD NEXUS CPL ALTERNATOR 0H6682 SD G4.2L G3 NEXUS 0H6683 WD G4.2L G3 NEXUS BACKPG001 BACK PAGE MANUAL 0H8218 CPL INSTALL MANUAL NON BRANDED

What’s the advantage of an aluminum enclosure? In addition to its sturdy galvanneal steel enclosure with RhinoCoat, Generac is one of the few companies to offer premium aluminum enclosures for its residential standby generators. Aluminum enclosures are naturally rust and corrosion resistant. For salt air or high humidity conditions, aluminum is highly recommended to ensure decades of worry free service.   Why should I buy an automatic standby generator instead of a portable generator? During a utility power outage, an automatic standby generator provides numerous advantages over a portable generator: The American Red Cross recommends permanently installed standby generators as a safer way to provide backup power to a home than a portable generator. With an automatic standby generator properly installed outside, your home is protected from deadly carbon monoxide poisoning that is a much greater risk with portable generators. Running on the home’s natural gas or LP fuel supply, it is less expensive to run than gasoline and does not need to be refilled. They start automatically within seconds of a power outage, and eliminate the need to haul a portable generator outside or run extension cords throughout your home. They provide protection 24/7, whether you’re home or away, and they turn themselves off when utility power returns, so there is no need to monitor the unit during an outage.
