Frequently Asked Questions

What’s the difference between standby and portable models?

Standby generators are permanently installed and wired to your home’s electrical system. Portable units plug in via standard outlets when needed.

How often should you run a home standby generator?

Generac recommends running weekly self-tests for 10-15 minutes under load. This helps prevent oil seal drying and ensures functionality.

What fuel do Generac generators use?

Most Generac home generators are dual-fuel capable, running on either natural gas or LP propane. Smaller portable models use gasoline.

What causes generator surging or pulsing of lights?

This usually indicates the generator is overloaded. Turn off some devices to bring the wattage draw down within the generator’s rated capacity.

How can I determine the right size generator I need?

Add up the starting wattage of essential appliances and devices you want to run. Choose a generator with at least that much starting capacity for a safe buffer.

Where are the best places to install a home backup generator?

Choose a location at least 15 feet from the home, away from windows and doors. Allow ample ventilation space. Local codes may apply.

How loud are Generac home standby generators?

Generac’s QuietSource series of home generators operate at just 63-69 dB, similar to normal conversation. Much quieter than older units.
