  9 Questions
Q: Can the air cooled unit operate in warm weather conditions and not overheat. We just had a 122 degree day and if the electricity had failed, would this generator be able to handle the load in the heat?
by Gene H. from California on June 27, 2016

A: Thank you for contacting us.

Generac Air-Cooled Standby Generators are tested in accordance to UL 2200 standards with an operating temperature of -20 ºF (-29 ºC) to 122 ºF for normal operating range

Please let us know if you have any other questions.
by Mike, Product Expert

Q: Should I pour a concrete base to place this unit on or can you place on a level dirt pad?
by Jim from Iowa on September 03, 2015

A: Thank you for contacting Electric Generators Direct.

I would advise pouring a concrete base. Or I would advise looking into a GenPad.

Q: Can aluminum wire be used to feed the breaker on a Generac generator?
by Glenn from New Jersey on December 11, 2014

A: Thanks for your inquiry.

When wiring the generator it must be in accordance with local jurisdiction and codes. If ALUMINUM conductors are used, apply corrosion inhibitor to conductors.

by Mike, Product Expert

Q: What is the clearance needed on all four sides of the unit for proper operation?

by Mark C. from Connecticut on July 24, 2014

A: Page 11 of the Installation Guide shows proper installation distances according to NFPA and manufacturers recommendations. The guide is available on our site under the specs tab in the download documentation section......

Q: If I'm not around when my home standby generator is running, what type of protections systems do the Generac units have?
by Josh from New Jersey on November 13, 2013

A: The generator may have to run for long periods of time with no operator present to
monitor the engine/generator conditions. Therefore, the generator is equipped with a number of systems to automatically shut down the unit to protect it against potentially damaging conditions. Some of these systems are as follows:

• Low Oil Pressure Sensor
• High Temperature Sensor
• Overcrank Sensor
• Overspeed Sensor
• RPM Sensor
• Under-frequency Sensor
• Undervoltage Sensor
• Overvoltage Sensor
• Internal Failure Sensor
• Low Battery Voltage Alarm

The control panel contains a display which alerts the operator when a fault condition occurs. The above list is not all inclusive. For more information about alarms and control panel operation, see Section 3 (Operation) in the owner's manual.

by Mike, Product Expert

Q: What type of oil should I use in my Generac home standby generator?
by Jim from Illinois on November 11, 2013

A: The maintenance section in the Generac's home standby owner's manual lists that the oil type is based on temperature ranges specific in your area.....

SAE-30 above 32º F (0º C)
10W-30 between 40º and -10º F (4º and -23º C)
Synthetic 5W-30 for all temperature ranges

All new models come with SAE-30 oil in them and have been test run at the factory for 25 hours and no break-in is required. The first oil change would be at 2 years or 200 hours, whichever comes first.

by Mike, Product Expert

Q: I'm not sure if this falls into the repair area but, I'm concerned about the sound this generator produces. Is there a way to lower that? Is there sound proofing approved for use for the interior walls of this type of home standby? My neighbors bedroom window will be 20ft from where I plan to install the generator. I would prefer doing something inside the generator as apposed to some type of fencing or other external methods.

by Mark H. from New Jersey on October 23, 2013

A: The manufacturers make every effort to reduce the sound of their generators as best they can keeping within NFPA and UL requirements. There are currently no options or parts available to install inside home standby systems to reduce their db(A) levels.

Your only option is location or sound barriers installed around the unit while keeping within NFPA and manufacturers distance requirements for proper fire protection, air intake and exhaust output.

We recommend consulting with your local inspector or AHJ (Authority Having Jurisdiction) as to the specific local code requirements.

by Mike, Product Expert

Q: Is the Smart Switch the actual Automatic Transfer Switch? Or are they different? The specs says that there is an automatic transfer switch included.

by Joseph P. from New York on October 21, 2013

A: The "smart switch" is the automatic transfer switch. The ATS has an internal load manager that will load shed up to 2 AC units preventing the overload of the generator at start-up.

Power Equipment Direct Recommended

This Generac 20kW standby generator is everything you need in one package. It is one of our best selling standby generators. The older model sold like hot cakes because it’s the ideal suburban power restoration solution.

At 20kW, the generator is so popular because at this size, it can power entire smaller homes, or restore the majority of power to larger homes. It comes with a 5 year warranty, which is as long as you can find in the industry.

Peace Of Mind
Haven't had an emergency yet so we can not speak to its operation, but the installer commented on its quality and the installation went without a hitch. The unit is not as loud as we expected.
Pros: Quiet, Price, Reliable
Cons: would like more info from the control panel.

James,
We're sorry to learn of the issues that you're currently experiencing with your personal unit. If a 20 kW automatic standby generator is ever unable to operate, an error code and corresponding message will appear on the unit's control panel. Once you are able to refer to the unit's control panel and acquire this particular code, please contact us directly at 888-GENERAC (436-3722) with the serial number of your personal unit for troubleshooting and servicing assistance. We look forward to providing further insight in the near future.
