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

Hurricane Matthew Is Foiled!
We installed the 22kw Generac whole house generator in August 2015. It runs itself for 5 minutes every 2 weeks, and even tells us when is time to check the battery! At 3:58am on 10/7/16 Matthew shut down our power. Within 30 seconds our entire 2400 sq ft. house, hvac and all was back under power. The Generac is so quiet we hardly noticed it was on for 18 straight hours. It is so far trouble free. We even ran an extension cord to one of our neighbors here is Titusville, Florida. My whole family... more

Not Sure. Product Shipped Quickly, But When Opened The Unit Was.
The product arrived with no damage to the shipping container. But when unpackaged the generator had impact damage to the ventilation louvers on one end with paint also chipped off. The concern is that if Generac allowed this unit to be packaged and shipped with known damage, what unseen internal issues are yet to be discovered. To be fair to EGD I have not contacted them yet as I am waiting for the electricians to connect unit and rule out any mechanical problems. Once unit is tested and... more

Excellent Product And Great Company To Do Business With
Easy to install if you have a little electrical and plumbing experience. Works flawlessly. Initially I was hesitant to make such a large purchase online. Turns out it was one of the most pleasant buying experiences I have ever had. It arrived on time in perfect condition. I could not be more pleased.
Pros: High Quality, Price, Quiet, Exceeded Expectations
Cons: All good so far.

So Happy To Have Peace Of Mind
So happy to have the peace of mind that we won't be without power again. Went 8 days without power during Hurricane sandy and the occasional power outages associated with NJ weather since then. The meant no heat, no hot water, no electricity. No more!

Of course, since it's installed, no outages, but our unit comes on every other week like clockwork without skipping a beat.
Such peace of mind is a blessing.
Pros: High Quality, Price, I'd Buy It Again, Reliable

Generac 22kw Purchase
In late March 2017 I placed the order for the Generac 7043 generator and transfer switch package. To take advantage of the discount offered, I sent a check and the generator shipped about eight or ten days later. It arrived on a lift gate truck and the driver was very helpful unloading the pallet. No damage or shortage everything went well. I opted to add the battery heater, oil heater and wireless monitor which were back ordered and shipped about two weeks later which worked out well for the... more

Glad I Made The Decision To Use Electric Generators Direct!
The primary we purchased this 22 KW Generac Guardian generator was to insure that when the power goes out I'm still able to operate my oxygen equipment. That said, being able to provide electrical power to the entire house without having to do anything was a super added plus! The unit was installed a little over a month ago since then we've lost power three times. The generator came on as a few seconds after we lost power and operated beautifully.
