Guardian 25 kW Generator Features and Benefits

The solid, reliable, increased horsepower of an automotive-style, liquid cooled engine provides whole house power protection for larger homes and essential circuit protection for small and medium businesses such as gas stations, restaurants and offices.


Guardian 25 kW Generator <strong>Features and Benefits</strong>

24/7 Automatic Backup Power
High-quality, liquid-cooled standby generator designed for larger homes and commercial buildings.

Quiet-Test™ Mode
All standby generators run a weekly test to ensure the system is running properly. Thanks to Quiet-Test, your Guardian Series home standby generator runs its self-test at a lower, quieter RPM than standard operation, and can be programmed to run weekly, bi-weekly, or monthly.

Powerful, Automotive-Style Engine
Powerful, liquid-cooled engine packs more power into a smaller footprint than air-cooled models.

Durable Steel Enclosure
Sturdy galvanneal steel enclosure with a durable powder-coat finish for superior weather protection.

Nexus™ Controller
Generac's Nexus™ Controller is the most comprehensive available. The dual line, tri-lingual LCD display allows for easy monitoring and management of generator functions.

Continuous Fuel Source - LP or Natural Gas
The engine runs on existing liquid propane or natural gas for a continuous, worry-free fuel supply.
