Losing power is no fun for anyone, especially homeowners. The lights cut out, appliances stop running, and AC shuts off, leaving you hot and in the dark. But thanks to Generac generators, you can keep essentials items powered up when the utility lines fail.
Generac makes high-quality, reliable home generators to seamlessly provide electricity during blackouts and storms. Having a Generac unit on standby gives homeowners peace of mind knowing their family, home, and valued possessions are protected.
In this guide, we’ll explore the best Generac generators for home installation across a range of power outputs, fuel compatibility, noise levels and smart features. Let’s review what Generac offers so you can decide which model is right for your needs when the lines go down.
Overview of Generac’s Home Generator Lineup
Generac designs several series of standby generators intended for residential use:
- Guardian Series – The most affordable and basic Generac models for essential backup needs.
- Evolution Series – Generac’s most popular home models with user-friendly digital displays.
- Elite Series – Top of the line Generac generators with maximum power and WiFi connectivity.
The aspects that differentiate Generac’s home generator models include:
- Fuel Compatibility – Natural gas, propane or diesel options available
- Power Output – Measured in kilowatts (kW), higher is more powerful
- Noise Level – Expressed in decibels (dB), lower is quieter
- Connectivity – Select models allow WiFi monitoring
Next, let’s explore these key factors in greater depth.
Key Generator Features to Consider for Your Home
Fuel Compatibility
Generac home generators run on three primary fuel sources. Each has pros and cons:
- Natural Gas – Connects to existing home gas lines. No refueling needed. Most popular option.
- Liquid Propane – Requires external fuel tank that needs periodic refills. Provides more placement flexibility.
- Diesel – Used in high end home models. Needs large external diesel fuel tank.
Most homeowners prefer the convenience of natural gas since it taps into existing utility lines. But propane and diesel give you more freedom on install location if needed.
Power Output
A generator’s power output determines how many appliances and devices it can run during an outage. This is measured in kilowatts (kW):
- 3250-6500W – Suitable for essentials like fridges, lights, furnaces, some small appliances
- 7500-11000W – Can power more lights, appliances, some AC units
- 16000W+ – Whole home coverage including central air and pool pumps
For a typical home under 4000 sq ft, a 7500-11000W unit will provide sufficient backup capability to run critical systems. Larger luxury homes will require 16000W or more for full power coverage.
Noise Level
Generator noise is measured in decibels (dB). The closer the dB is to 60, the quieter the unit operates. Key home decibel levels:
- Standard units = 62-69 dB range during operation
- QuietSource models = Ultra quiet 59-62 dB for minimal sound
If your generator will be near living spaces or you have close neighbors, look for QuietSource models rated at 62 dB or less.
Connectivity
Some premium Generac models allow full WiFi connectivity to enable remote monitoring and control from smartphones. Benefits include:
- Real time status updates and outage tracking
- Generator health diagnostics
- Maintenance reminders and notifications
- Access anywhere via cellular connection
WiFi capability provides maximum convenience but does add cost over basic models. Consider if it’s worth the investment based on your needs and technical skills.
Now let’s review some of the best Generac generators suited for home installation.

How to Choose the Right Generac Generator for Your Home
Choosing the proper Generac generator involves more than just your budget. Consider these factors:
- Make a list of essential appliances and devices you’ll want powered during an outage to guide your wattage needs.
- Estimate your home’s square footage as smaller units often suffice for condos while larger homes need more output.
- Determine which fuel type – natural gas, propane or diesel – makes sense for your home’s existing hookups and placement.
- Review the posted noise levels and your proximity to neighbors to decide if a QuietSource model should be chosen.
- Decide if WiFi capabilities for remote monitoring appeal to your needs and lifestyle or if a standard unit will do.
- Have an electrician size your transfer switch and circuit breakers to integrate the generator properly.
- Pick an outdoor location that provides proper ventilation and clearance from windows, doors and ground.
- Work with a licensed Generac dealer for professional local installation and permitting.
- Compare pricing across authorized Generac dealers using MSRP as a baseline. Dealers may offer discounts.
Choosing the appropriate sized unit for your actual power consumption, rather than overbuying, ensures your generator operates optimally when needed most.
