Powering Through Outages: Choosing the Best Generac Home Generator for Your Needs

Power outages can happen when you least expect them. Severe weather, grid failures, even squirrels chewing through power lines can leave you sitting in the dark. Having backup power is crucial to keep your home livable and safe during extended outages.

Generac is one of the most trusted brands when it comes to home standby generators. With a wide range of models to choose from, Generac has a solution suitable for small homes up to large properties.

In this comprehensive guide, we’ll explore the key factors in picking the right Generac generator. We’ll also review the top-rated Generac models and provide helpful tips for installation, maintenance and operation.

Let’s get started!

Selecting the Ideal Generac Generator for Your Home

Choosing a home backup generator is not a one-size-fits-all scenario. You need adequate power to run essential appliances and systems, but you don’t want to overspend on a larger capacity than you need. With Generac’s diverse product line, you can zero in on the best size generator for your home’s electrical requirements.

Here are the key factors to consider:

Fuel Type

Generac generators can run on either natural gas or liquid propane. Natural gas generators connect directly to your home’s gas supply line. This provides a limitless fuel source as long as the main line is active.

Propane generators require an external tank to be refilled periodically. Propane gives you more placement flexibility if natural gas isn’t available. Compare fuel availability and costs in your region.

Power Output

Generac home generators are rated by kilowatts (kW) of power they can produce. This determines how many appliances/systems the generator can run. Audit your home’s electrical load and get a generator that meets it, without excessive overcapacity.

Noise Level

Larger generators make more noise. Measure the decibel levels of different Generac models and choose one that won’t disturb you excessively. Sound enclosures can reduce noise.

Placement

Stand-by generators are permanently installed outside and connect to your home’s electrical panel to power circuits. Portable generators are moved manually to run specific appliances indoors/outdoors.

Features

Larger Generac models offer advanced features like WiFi monitoring, extended runtime, quieter operation, whole house coverage etc. Choose features that best fit your budget and needs.

Smooth Generator Installation and Ongoing Maintenance

Proper generator installation and maintenance ensures your Generac investment provides years of reliable service when you need it most.

Installation – DIY or Professional?

Standby generators require significant electrical wiring, fuel line connections and concrete mounting pads. Generac recommends professional installation for any permanently wired standby unit.

For portable generators, you can safely handle the electrical connections yourself using temporary extension cords and power strips. Use portable models outdoors only.

Regular Maintenance is Crucial

Follow Generac’s maintenance schedule to keep your generator operating at peak efficiency. This involves periodic inspections, oil changes, battery replacement, fuel line/filter changes, testing etc. Neglecting maintenance can severely shorten a generator’s lifespan.

Stock up on spare parts like air, oil and fuel filters. Schedule annual servicing by a Generac authorized dealer to keep warranties valid and catch any issues.
