Automatic Backup for Large or Custom Homes
Looking to back up your entire home, or more items than usual? Consider the Protector Series gaseous automatic backup generator line. These units power essential appliances and modern technologies during power outages, allowing homeowners and their families to continue living life comfortably and without interruption.

What Makes the Protector Series Such a Great Choice?
Generac's Protector Series offers benefits that competitors can’t match: installation flexibility and cost reduction. Sophisticated, yet intuitive controls. Quiet operation. Supported by a 24/7/365 customer support team at our corporate headquarters, and a nationwide dealer network of more than 6,000 strong.

The best liquid cooled engine packs more power into a smaller footprint - ideal when space is a premium. The neutral styling, color and small footprint fits unobtrusively into landscaping. Clean burning, continuous fuel choice of natural gas to LP.

True Power™ Technology
Delivers best-in class power quality with less than 5% total harmonic distortion (THD) for clean, smooth operation of sensitive electronics and appliances.

Evolution™ Controller
A cutting-edge, intuitive control. The Evolution controller features a multilingual, two-line LCD text display with color-coded, backlit buttons. It has received upgrades, including USB flash capability, smart battery charging, voltage adjustment, and backlit membrane pad-style buttons.

Can Be Installed Just 18" From a Structure
Capability to be installed 18 inches away from a structure, ideal for areas with tight lot lines. Generac is the only manufacturer of standby generators to have 18” offset on most of its residential lineup.

Tough, Durable All-Aluminum Enclosures
Our RhinoCoat™ powder-coated finish helps make corrosion-resistant aluminum perfect for all weather conditions.

All backup generators run a weekly test to ensure the system is running properly. Thanks to Quiet-Test, your Protector Series home generator runs its self-test at a lower, quieter RPM, which can be programmed to run weekly, bi-weekly, or monthly.

Additional Features
Improved stub ups and electrical connection access decrease installation costs. All connections are dual conductor rated, and the implementation of quick connects for the control wires, completely eliminates the need for crimping or lugging.
Improved customer connection access, which decreases installation costs.
