Generac Guardian Home or Office Residential and Commercial Stand By / Back Up Emergency Power Generator Systems
Natural Gas or Propane (LP) Powered Complete Systems including Automatic Transfer Switch, Wiring, and pad / slab.

PRODUCT DESCRIPTION
Generac Power Systems, Inc. manufactures a complete line of emergency automatic home standby generators that can be installed during new construction or retrofitted into existing residences and businesses. Residential emergency home standby generators are permanently installed outside (similar to an air-conditioning unit), supply electrical power to all pre-selected lights and appliances, and are powered by either natural gas or LPG. Models range from 7,000 to 45,000 watts. They work with a matched automatic transfer switch that responds within seconds when utility power shuts down, even when no one is home!

Generac is truly a vertically integrated manufacturer. From the core of the engine to the controls, they design and build their complete product. This is precisely why they stand so strongly behind it with one of the best warranties in the industry. With intensive control over their engineering through manufacturing, they're able to ensure that their products are quiet, powerful and reliable.

FEATURES & BENEFITS
The RESIDENTIAL EMERGENCY HOME STANDBY emergency power generator is the most powerful, fully automatic, enclosed generator of its size available anywhere. The liquid-cooled models deliver up to 45,000 watts of backup electrical power and the air-cooled models produce up to 15,000 watts. They are quiet, reliable and loaded with special features.

UL-Listed Automatic Transfer Switch

  • Automatically signals the generator to produce emergency electrical power when utility fails and disconnects when utility power returns.
  • Within seconds your generator is producing electrical power without you having to even flip a switch. You don't have to be home for your system to work!

Automatic Exerciser

  • Seven (7) day interval testing of the power generating system.
  • You set the system to exercise at a prescribed time and day of the week. This allows you to verify that your system is in peak operating condition between utility failures.

Convenient Fuel Supply

  • Operates on home/business natural gas or LP gas service.
  • Provides you with potentially unlimited run time during extended utility power failures.
  • On Board LED System Fault Indicators - low oil pressure, high engine temperature shutdown, overspeed/overcrank shutdown and system ready light (air-cooled models only).
  • Aids in performance of servicing in the event of a system difficulty. Leads technician to a more specific area for troubleshooting purposes. Reduces service time.

OHVI® Single or Twin-Cylinder Engine

  • Full-pressure lubrication system with automotive spin-on oil filter (air-cooled only).
  • Finest lubrication technology available and provides instantaneous disbursement of lubricant to all engine parts. Easy change filter.

Automatic Voltage Regulator

  • Maintains constant voltage with varying loads.
  • Eliminates voltage spikes and allows operation of sensitive electronic equipment.

Maintenance Friendly

  • Air-cooled models include a hinged top and removable front panel. Liquid-cooled models feature large removable enclosure doors.
  • Provides easy and quick access to all maintenance and service parts. Reduces preventative maintenance or repair time.

 

HOW DOES THE SYSTEM WORK?
Automatic Back Up Generac Guardian generator propne natural gas back up system
  • The completely automatic Guardian transfer switch monitors incoming voltage from the utility line - around the clock.
  • When utility power is interrupted, the automatic transfer switch immediately senses the problem and signals the generator to start.
  • The automatic transfer switch then safely closes off the utility line and simultaneously opens a new power line from the generator.
  • Within seconds, your Guardian generator system begins supplying electricity to the critical emergency circuits of your home or business. The transfer switch continues to monitor the utility line conditions.
  • When the automatic transfer switch senses the utility line voltage has returned at a steady state, it re-transfers the electrical load back to the utility line and resumes monitoring for subsequent utility loss. The generator will continue to run for an engine cool-down period of several minutes while the entire system stands ready for the next power outage.
  7, 12 & 15 kW SPECIFICATIONS
  • Quiet, powerful Generac OHVI single-cylinder or V-Twin engines fueled by natural gas or LP gas.
  • UL Listed remote-mounted pre-wired automatic transfer switch with 8, 10 or 12 circuit emergency load center for fast and efficient unattended transfer to generator when utility power fails.
  • A standard weather protective enclosure with sound-absorbing panels protects generator from harmful weather and also reduces exterior noise levels. Includes key locks for security.
  • Hinged top and removable front panel for easy serviceability.
  • Built-in charger maintains battery at optimum performance level.
  • Automatic safety shutdowns protect engine and generator in event of low oil pressure, high temperature, overspeed and/or overcrank.
  • Automatic seven-day exerciser runs the system for twelve minutes weekly to maintain top running condition.
  • Installation system includes the pre-wired automatic transfer switch with built-in load center, 30' and 2' wiring harnesses, pre-wired external connection box, 1' flexible fuel line, "Do-It-Yourself" installation guide and a composite mounting pad.
