How to Choose the Right Generac Standby Generator
Generac offers home standby generators in a range of sizes and with various fuel options. Consider the following when picking the right model:
Fuel Type
Generac standby generators run on natural gas or liquid propane. Natural gas provides continuous fuel during an outage. Propane allows flexibility in placement. Compare fuel availability and costs in your area.
Power Output
Measure your home’s essential electrical loads and size the generator at least 20% larger. A 7-22kW unit covers most homes. Get an in-home assessment for your exact needs.
Placement
An outdoor concrete pad meets code requirements for permanent standby generators. Pick a location away from windows and doors for proper exhaust venting.
Noise Level
Larger generators emit 62-74 dBA of noise. Weatherproof enclosures further reduce sound. Compare noise levels across models to find an acceptable range.
Additional Features
Evaluate connectivity options, exercise schedules, home automation integration, extended runtimes, and warranties across Generac models to determine what additional features you may want.
