Additional information for Synergy 20kW Generator

Patented G-Flex™ Technology
Allows the Generac Synergy home standby generator to vary its speed based upon electrical demand. It will run slower—and quieter—when you use less electricity. And during its weekly exercise, you’ll hear only about as much sound as if you were riding in a luxury car. The Synergy also consumes less fuel when electricity demand is light, saving you money. And G-Flex technology delivers electricity with less than 2.0% total harmonic distortion (THD)—lower than IEEE standards for utility power— to properly power modern electronics and sensitive appliances.

Generac OHVI® Engine
Your Generac Synergy generator might have to get you through days—or weeks—without utility power. Generac’s OHVI® engine, specifically designed for generator use, provides the reliability to power through the most severe outages.

Evolution™ Controller
The next generation of intuitive controllers featuring a multilingual, two-line LCD text display with color-coded, backlit buttons.

Mobile Link™ Cellular Remote Monitoring
Check on your generator’s status even when you are away with Mobile Link cellular remote monitoring. Use your computer, tablet, or smartphone. Downloadable app available for iOS® and Android™. Comes standard with Generac Synergy.

Certified for 18" Installation to the Home
Third-party certified to NFPA standards to be installed as close as 18” from the home’s exterior wall, provided it is located away from doors, windows, and fresh-air intakes, and unless otherwise directed by local codes.

All-Weather Aluminum Enclosure
Our durable powder-coat finish helps make the sturdy aluminum enclosure perfect for all weather conditions. It’s also able to withstand 150 mph winds.

Tool-less Fuel Conversion
The Generac Synergy runs on natural gas and LP fuel, and easily converts during installation without the need for tools.

Quiet-Test™ Mode
G-Flex™ technology allows the Generac Synergy to run at a very low speed during its periodic exercise. You’ll hear about as much sound as you would riding in a luxury car. Select weekly, bi-weekly or monthly for just 5 minutes.

24/7/365 Customer Support
Power outages don’t always occur during normal working hours. That’s why Generac’s customer care call center—right here in Wisconsin—provides support any time of day or night, all year long. Generac is standing by 24/7, every minute of every day, to answer your questions.

Power Management Module

Meet the brains that make smart power possible.

These modules are essential to a Generac power management system. They work with your transfer switch, monitoring each selected circuit and automatically supplying power where it’s needed so you can get the most from your generator.

A Generac power management system can use up to eight individual Smart Management Modules, depending on your needs. Just as important, you can set the load priority for each – putting you in control of which circuits matter most.
