Generac Generator Buying Tips
Generac Generator Buying Guide
So, you’ve heard about the benefits of Generac generators and are interested in installing one in your New Jersey home. Excellent choice! Generac has been a trusted name in residential and commercial backup power since 1959. Review this Generac generator buying guide for tips to ensure you select the perfect model for your needs.

Tips for Buying a Generac Generator
Conduct a Power Audit
The first step is to determine how much power you actually need. A power audit involves listing all the appliances and systems you want to run during an outage—for instance, your refrigerator, freezer, HVAC system, sump pump, microwave, TV, garage door opener, and lights. Each device has a specific wattage requirement, so tallying these up using a Generac generator size calculator gives you a clear picture of the capacity you need.
Choose the Right Size
Once you’ve completed your power audit, you’ll better understand the generator size required. Your power needs may fall into one of these categories:
- 7kW to 12kW generators power the essentials.
- 13kW to 26kW generators provide mid-range power for a moderate price.
- 27kW to 150kW generators offer whole-house power, the largest of which keep large estates and small businesses humming during power outages.
Consider the Fuel Type
Generac generators run on one of these fuels:
- Natural gas provides a continuous fuel supply with no onsite storage required. It’s the most cost-effective but requires a natural gas line connection.
- Liquid propane (LP) offers a longer shelf life and burns cleaner than diesel but requires storage tanks that need regular refilling.
- Diesel is known for its efficiency and energy density. However, diesel generators are noisier and must follow stricter storage regulations.
Evaluate Key Features
Here are some Generac generator features to consider:
- An automatic transfer switch (ATS) ensures a seamless transition to generator power during an outage.
- Wi-Fi connectivity allows for remote monitoring and real-time alerts.
- A low noise rating minimizes disturbance in residential areas.
- A durable enclosure protects the generator from harsh weather.
Understand Warranty and Maintenance
A generator is a big investment, so it’s wise to review the warranty terms. Generac generator warranty information varies by model, typically covering parts and labor for a set period. Be aware that regular maintenance is required to uphold warranty coverage. Failing to keep up with tasks like changing the oil and oil filter, inspecting the air intake system, and cleaning the generator could void the warranty.

Top Generac Generator Models
Generac offers a diverse lineup of generators for various needs and applications. Here’s a breakdown of some of the best Generac generators for home use.
Guardian Series
The Guardian Series is Generac’s most popular residential line. These generators kick in automatically within seconds of detecting power loss and run uninterrupted until utility power returns. They offer flexibility, quiet operation, and the best value-per-kilowatt in the industry.
EcoGen Series
Specifically designed for off-grid use, the EcoGen Series integrates seamlessly with alternative energy systems like wind or solar power. These generators feature extended run capacity and lifespan, premium oil recovery and circulation systems, and exceptional protection against the elements.

The Centurion Series is fully automatic and can protect your entire home or just the most essential items. These generators are reliable in even the most extreme power loss scenarios, combining a premium engine, weekly quiet self-testing, and remote monitoring.
QuietSource Series
This series is ideal for larger homes or those requiring backup power for garages, pools, or guest houses. It features a low-RPM liquid-cooled engine for additional power yet still delivers extra-quiet operation and reduced fuel consumption.
