Power Output: 14 kW

This number reflects the maximum continuous power the generator can provide. For an average-sized home, a 14 kW generator is usually enough to run lights, the refrigerator, HVAC, and a few outlets. However, it may not be able to support large energy consumers like central air conditioning, an electric range, and other high-demand appliances all at once. If you have a very large home or want to run multiple high-consumption devices simultaneously, we recommend getting a larger generator.

Generac 14kW Fuel Type: Liquid Propane or Natural Gas

The generator can run on either liquid propane or natural gas. Each has its own advantages. Liquid propane is stored in tanks while natural gas is supplied directly from a gas line.

Propane generally costs more per unit of energy compared to natural gas, but has the benefit of being independent from utility services. If you already have propane tanks in place, or want ultimate off-the-grid freedom, liquid propane might be right for you.

Natural gas, while usually cheaper and more convenient because of its continuous supply, needs an uninterrupted connection to the gas grid. While this usually isn’t an issue during power outages from things like snowstorms or high winds, the gas grid can be interrupted from natural disasters like earthquakes or for maintenance reasons.

Battery Type: Group 26R 540 CCA Minimum or Group 35AGM 650 CCA Minimum

These battery types are common in mid-sized standby generators. “CCA” stands for Cold Cranking Amps, meaning the battery’s ability to deliver a certain amount of current at 0°F for 30 seconds without dropping below a specified voltage. This is important for starting the generator reliably in cold weather.

“AGM” stands for Absorbed Glass Mat. These batteries use a special fiberglass mat to hold the electrolyte in place. The design also allows for faster recharging, deeper discharge cycles without damage, and better performance in extreme temperatures compared to traditional flooded batteries.

Group 26R 540 CCA Minimum is a more compact, less expensive option, similar to a car battery. It can function reliably in moderately cold temperatures, typically down to around 0°F to -10°F, but may struggle in extreme cold.

Group 35AGM 650 CCA Minimum provides higher cold cranking amps and performs better in very cold conditions, typically maintaining reliable performance in temperatures as low as -20°F to -30°F.

Engine Type: G-Force 800

This engine is built specifically for standby generators. It uses full pressure lubrication, which consistently delivers oil to key engine components, helping the engine run smoothly and reducing wear. This results in less frequent maintenance compared to splash-lubricated, air-cooled engines that are often used in lower-cost generators. The G-Force 800 is reliable and designed for extended operation during power outages.

Weight of Generac 14kW: 385lb

This weight is typical for a mid-sized generator. To function reliably, the generator needs a level foundation, like a concrete or prefabricated composite pad, to prevent shifting or settling over time.

Other Features of the Generac 14kW

True Power™ Technology to reduce total harmonic distortion to less than 5%. Total Harmonic Distortion (THD) is a measure of how “clean” the electricity is. In a generator, low THD means the electricity is smooth and stable, which is important for sensitive devices like computers, TVs, or medical equipment. If the THD is too high, the power can be “jumpy” and cause those devices to overheat, malfunction, or get damaged.

Because this generator has low total harmonic distortion, it’s safer to use on sensitive devices – like computers – than electricity from older or budget generators.

The Quiet-Test™ Self-Test Mode operates at a reduced RPM, typically running at around 1800 RPM, compared to 3600 RPM in traditional testing modes. This lower RPM can reduce noise levels by up to 50%, bringing the generator’s sound output down to about 55-60 decibels, compared to the 70-75 decibels made by traditional test modes. Every standby generator needs to be tested regularly to make sure it works when the lights go out, but not every generator is this quiet while doing it.

Powder-coated aluminum for corrosion resistance. The RhinoCoat™ Enclosure is built to outlast harsh weather. Low-cost generators often use plastic housings or steel enclosures that are less durable or rust over time.

The Evolution™ Controller Multilingual LCD display is a user-friendly control system for monitoring battery status and scheduling maintenance. You’ll never have to guess what a  hard-to-read gauge might be saying.

Wi-Fi enabled Mobile Link™ Remote Monitoring allows you to access the generator status from your phone, computer, or tablet so you’re always up to date. Knowing exactly how your generating is operating helps to give peace of mind wherever you might be.

Generac 14 kW Home Standby Generator: Frequently Asked Questions

How do I know the generator will pass local regulations and codes?

The Generac 14 kW generator models are designed to be EPA and CARB compliant, so you can use them in areas with strict emissions requirements. They are also ETL and UL 2200 certified, meaning they have passed high safety standards.

Can the 14 kW Generac generator handle running all of my major appliances at once?

While the 14 kW generator is capable of powering many appliances individually, it may not be able to run all major appliances simultaneously, especially if you have a large home with multiple high-wattage devices.

Contact us and we’ll help figure out the best size of generator for you.

How much does the 14kW Generac cost?

$5800+/- for the generator itself.

A pad for the generator, transfer switch,installation, wiring, and fuel tanks are additional to the generator cost. The exact amount varies depending on your specific situation.

Do you have any payment plans?

Yes, we offer financing.  Please contact us for more information.

From the time I first contact you, how long will it take to have the generator installed?

Typically, the installation takes between 4-6 weeks from confirmed purchase to installation. This includes an initial consultation, site evaluation, getting any necessary permits, and scheduling the installation. For a more precise timeline, contact us to go over the details specific to your location and situation.

How often do I need to service the generator, and will it be expensive?

Backup generators like the 14 kW Generac require the initial 25 hour break in service when new and thereafter need servicing once a year or after every 100 hours of use, whichever comes first. Regular maintenance includes oil and filter changes, air filter replacements, spark plug replacement, valve adjustments, cleaning and waxing of the unit and testing the generator. The cost of servicing can vary based on your location, the generator model.

What happens if there’s a problem with the generator after installation? Is there a warranty?

Generac’s 14 kW generators come with a 5-year limited warranty that covers parts and labor for repairs due to defects or problems under normal use. If an issue arises after installation, you can contact us to assess and repair the unit. Regular maintenance is required to keep the warranty valid.

Can I monitor the generator remotely, especially if I’m not home when the power goes out?

Yes! The 14 kW Generac includes Wi-Fi enabled Mobile Link™ remote monitoring. This lets you monitor the status of your generator from anywhere using a smartphone, tablet, or computer. You can check if the generator is running, review maintenance schedules, and receive alerts about issues, like low fuel or required maintenance.

If the power goes out, could I use the generator to charge my electric vehicle?

You should be able to use a 14 kW generator to charge your electric vehicle (EV), but it depends on the power requirements of your EV and other power consumption. Most EV chargers need around 7-10 kW, so as long as your generator isn’t powering too many other high-demand appliances, it should be able to handle charging the vehicle. Keep in mind that charging times may be longer compared to using grid power, and it’s important to verify the generator’s capacity with the specific requirements of your EV charger.

What type of fuel does the Generac 14kW home standby generator use?

Either liquid propane stored in tanks, or natural gas from your home’s gas line.
