When the power goes out, a reliable home generator keeps your lights on, appliances running, and family safe. Generac is one of the most trusted brands in backup power solutions, offering a range of models to fit different home needs. But how do you choose the best Generac generator for your home? This guide covers everything you need to know—from wattage requirements and fuel types to installation tips and top Generac models. Let’s dive in.
Why Choose a Generac Home Generator?

Smart Technology: Wi-Fi monitoring lets you check status and maintenance alerts from your phone.
Wide Range of Options: From small portable units to whole-house standby systems.
Now, let’s break down the key factors in choosing the right Generac generator.
How to Choose the Best Generac Generator for Your Home
Determine Your Power Needs (Wattage Requirements)
The first step is calculating how much power your home requires. Generators are rated in watts (W) or kilowatts (kW), and you’ll need to account for:
Starting Watts (Surge Power): Some appliances, like refrigerators and air conditioners, need extra power when they first turn on.
Running Watts: The continuous power needed to keep devices running.
Standby vs. Portable Generators
Generac offers two main types of home generators:
Standby Generators
- Permanently installed outside your home.
- Automatically turn on during outages.
- Powered by natural gas or propane.
- Best for whole-home backup power.
Best for: Homes in areas with frequent or long outages.
Portable Generators
- Mobile and can be stored when not in use.
- Require manual setup and fueling (gasoline or propane).
- Lower upfront cost but less convenient.
Best for: Occasional use or powering select appliances.
Fuel Type: Gas, Propane, or Natural Gas?
- Gasoline: Common in portable models but requires fresh fuel storage.
- Propane: Cleaner burning and stores longer than gasoline.
- Natural Gas: Connects to your home’s gas line (standby generators only).
- Best choice: Standby generators with dual-fuel (propane + natural gas) offer flexibility.
Noise Levels (Decibel Ratings)
Generators produce noise, measured in decibels (dB).
- Quiet models: ~60 dB (similar to a conversation).
- Loud models: ~75 dB (like a vacuum cleaner).
- Tip: Look for models with sound-dampening technology if noise is a concern.
