Q: What size do i need for 1800 so.ft
by Anthony H. from Texas on July 01, 2016

A: Thank you for visiting Electric Generators Direct.

In regards to your question, proper sizing of the generator is crucial to the success of any installation and requires a good working knowledge of electricity and its characteristics, as well as the varying requirements of the electrical equipment comprising the load.

When analyzing the electrical load, consult the manufacturer’s nameplate on each major appliance or piece of equipment to determine its starting amperage. The following formula can help determine the starting wattage. (Starting Amps x Volts = Watts) When choosing the generator output select a rating that is approximately 20 to 25% higher than the peak load (for example, if the load is about 8 kilowatts, select a 10 kW generator).

A higher rated generator will operate comfortably at approximately 80% of its full capacity and will provide a margin of flexibility if the load increases in the future. A certified electrician should be consulted for proper sizing and installation of any generator.

I have attached an estimated Generator sizing calculator is help you estimate the size to get started.

Q: I just bought 22k Generac it will be 70' from the propane tank what size flex piping should i buy?
by Dennis K. from Wisconsin on June 30, 2016

A: Below is a link to the Install Manual that will cover the pipe sizing using LP. I recommend checking with a plumber or LP company for installation of the gas line.

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.

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.

Generac is the only manufacturer that offers a 22kW air cooled home standby generator . This unit is unlike any home standby currently available and is far below the price of a comparable liquid cooled model.

At 22kW, model 7043 is the largest air-cooled generator on the market. This model is equipped with a 5 year warranty, and has all of the features and functionality that customers have come to expect from the number one standby generator manufacturer. Generac, through strategy and... more

Excellent Experience
The purchase was flawless and the installation (by licensed electrical) was great. The impressive part was that when my electrician called Generac to "Activate" the account, Electric Generators had supplied all of the pertinent end-customer information to Generac, prior to activation. . . Very Impressed!

The equipment was shipped as promised, delivered to my home on a truck that had a power lift gate and the equipment to set the pallet on the drive-way awaiting my installation. . .EXCELLENT!

Little Worried!!
From the start, couldn't get it to run smooth, both unloaded and loaded. Everything was done at installation that Generac had instructed. Generac representative said that he had seen 3 that had the same problem. Said Generac had not determined the correct fix. Finally after changing air filter that came with it to another one and trying other things, it finally smoothed out. My worried is that if it comes on while I'm away and starts running rough, it would cause damage to my appliances. I... more

Brody,
We apologize for any problems you're having with your generator. Generac has never notified us of any issue with these units. Please keep in mind that Generac stands behind their products and provides a 5-Year warranty on the model.

Security Is A Good Thing
My Generac is not unattractive as generators go, however my HOA requires it to be screened from public view by shrubbery. It does give me a secure feeling, similar to home insurance, which is required.I hope I never need it.
Security does have value which Generac provides at reasonable cost.

My Generac Installation Experience
The generator was shipped within 5 days of purchase, however the trucking company destroyed it. However. Electric Generators Direct shipped a replacement by 1:00 PM the next day. That one was fine and met all expectations. A word to the wise. If you intend to purchase yourself, and have a licensed electrician do the wiring for permit purposes, be sure you spell it out in writing who is responsible for what.

Do Your Homework
If your going to purchase the generator yourself and have an electrical contractor install it, get a reliable cost estimate on the installation cost. This should include a walk-through with the contractor to verify the location is good for connection to your power supply and fuel for the generator before you make the purchase. There are code restrictions as to placement.

Also, review the accessories that might get added to the generator and determine the cost to install. Some simply are... more

The 22kw standby generator was installed by a local electrical and refrigeration company. The start-up process was more difficult than normal because the 200A disconnect came with a faulty fuse (BBS-5 600 VAC). This was discovered after going threw the start-up procedure with a factory rep.. The faulty fuse was preventing the generator from shutting down after the main power was resumed.

Couldn't Be Happier
Last year with Hurricane Hermine we lost power for 5 days, six months later local tornadoes interrupted our power for 3 days. Determined not to go thru this again I contacted our local electrical contractor for assistance. He recommended the Generac 22kw generator.

Installation went well and initial start up by our local general service rep was easy. Shortly after installation hurricane Irma hit. We lost power at 4 am. The generator started 5 seconds later and ran continuously for 14 hours... more

House Flooded in August, lost our generator. Had been looking / searching to upgrade prior to flood. (We had a 15 KW). After I found there web site, I couldn't find anyone else that could compete with there pricing. Ordered online, shipping was fast. After the install, this 22KW works flawlessly. Would most definitely recommend this generator.
