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. Simple field conversion from natural gas to LP. Generac OHVI Engine was designed specifically for generators. It out peforms most competitive generator engines with an engine life that is three to four times longer and has a significantly longer period between scheduled maintenance checkups. Trupower Technology provides clean, smooth operation of sensitive electronics and appliances. Sturdy, Aluminum enclosure with RhinoCoat™ are naturally rust and corrosion resistant. For salt air or high humidity conditions, aluminum is highly recommended to ensure decades of worry free service. External “At-a-Glance” indicator lights offer an easy way to tell generator status without opening the generator enclosure. Added Sound Reduction with enclosures that are lined with sound reducing foam panels for further noise reduction. Hour Meter monitors run time, providing information to determine maintenance intervals. Easiest installation on the market and an excellent value when purchased pre-packaged with a pre-wired transfer switch, or customize your system by purchasing the generator and transfer switch separately. Composite mounting pad is included, eliminating the need to pour a concrete base.

Revolutionary way to complete the standby generator system, the combination of the Nexus Smart Switch and the Nexus Controller adds up to Generac’s Nexus Smart System. The smartest air-cooled switch/controller system available, It efficiently manages two large loads without additional components, a function not possible with a standard transfer switch. Add optional Digital Load Management (DLM) modules for intelligent management of up to four more loads. It also provides the most comprehensive display of alarms and system stats. From monitoring to load management, owning a standby generator system has never been easier.

How it works · By monitoring generator engine performance, the switch is able to identify when the generator approaches overload. At the appropriate time, the switch disconnects two air conditioners, typically the highest electrical load in the house. · After a 5-minute delay to allow for compressor bleed out, the switch brings the AC units back online one after the other with a 30-second delay in between. This is a standard capability in all Generac Smart Switches and does not require any additional components, unlike competitive transfer switches. · In addition, up to four other large 240V loads can be managed when the Smart Switch is used in conjunction with individual DLM modules. These modules are 50 amps each and are housed in a NEMA 3R enclosure, giving the installer the option to install them either at the electrical panel or anywhere in-line indoors or outdoors between the electrical panel and the appliance. After the four loads are shed, they are brought back individually to assure DLM Module generator capability and eliminate the potential of overload.

Cycle on and off two air conditioners without additional components, allowing for a smaller generator to cover more circuits.

	Installation Overview

GFCI Plug On Outside Of Generator

Whole House Transfer Automatic Transfer Switch is Service Entrance Rated with a 200 amp transfer switch to disconnect utility power. No need to select the circuits needed during emergency All Circuits come on during loss of power from the utility Once power is restored from the utility the transfer switch will transfer back and the generator will shutdown Time to transfer is only 20 seconds

How Automatic Standby Generators Work View the OHVI Engine Video

The Power Behind the #1 Home Standby Generator Geneac OHVI® engine Generac has engineered and manufactures the only true generator engine.Why is this important? Generators are often required to run for hours at a time, day after day. Generac’s OHVI engine utilizes the same type of pressurized oil lubrication used to give automobile engines long and trouble free lives. This means a significantly longer life than competitive engines - an unprecedented three to four times longer.

NEXUS CONTROLLER FEATURES The new Nexus controller for air-cooled generators (8 -20 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

GENERATOR SIZING By sizing your generator according to your needs instead of your home’s square footage, you won’t overspend or be surprised by inadequate coverage. Decide what items are important to you in a power outage. these items are powered through circuits in your breaker box. the number of chosen circuits decides your generator size. Use this chart as a guide to determine the power you need.
