Powerful Standby Power for Large Homes and Businesses

Power outages can cause major disruptions to daily life and business operations. Refrigeration fails, security systems shut down, and heating or cooling systems stop working. A properly sized whole house standby generator eliminates these risks.

The Briggs and Stratton 60kW generator is engineered to support large electrical loads commonly found in luxury residences and commercial buildings.

Typical applications include:

• Large residential homes with multiple HVAC systems
• Restaurants and retail stores
• Office buildings
• Medical or dental clinics
• Data and server rooms
• Farms and agricultural facilities

When utility power fails, the generator automatically detects the outage and restores electricity within seconds using an automatic transfer switch.

This ensures essential systems remain operational without manual intervention.

Advanced 5.7L Liquid-Cooled Engine Technology

One of the key advantages of the Briggs and Stratton Fortress generator is its powerful PSI 5.7-liter V8 engine.

Unlike smaller air-cooled generators that operate at 3600 RPM, this liquid cooled generator runs at 1800 RPM.

This design provides several important advantages:

1. Lower operating noise
Slower engine speeds reduce vibration and mechanical noise.

2. Longer engine lifespan
Reduced wear on internal components extends durability.

3. Higher reliability under heavy load
Liquid cooling prevents overheating during extended operation.

4. Better fuel efficiency
Lower RPM engines generally consume less fuel under comparable loads.

This engineering approach is why large commercial facilities prefer liquid cooled standby generators for long-term reliability.

Heavy-Duty Galvanneal Steel Enclosure

Outdoor standby generators must withstand harsh weather conditions including rain, snow, humidity, and extreme temperatures.

The Briggs and Stratton 60kW generator uses an automotive-grade galvanneal steel enclosure designed to resist corrosion and rust.

Advantages of this enclosure include:

• Long-term durability
• Weather resistance
• Reduced maintenance
• Protection from environmental damage

Galvanneal steel is commonly used in the automotive industry due to its excellent resistance to corrosion.

This design ensures the generator remains protected during years of outdoor operation.

---

Flexible Installation Design

Installation flexibility is another key advantage of the Briggs and Stratton Fortress generator.

The unit is rated for placement as close as 18 inches from the building, allowing it to fit into tight installation spaces where larger clearance would normally be required.

Important installation considerations:

• Prepared mounting pad required
• Installation must follow local electrical codes
• Automatic transfer switch required (sold separately)

Professional installation is recommended to ensure proper electrical integration with the building’s power system.

---

InfoHub Wireless Monitoring

Modern standby generators increasingly include remote monitoring capabilities.

The optional InfoHub wireless monitoring system allows users to check generator status from a smartphone, tablet, or computer.

Key features include:

• Real-time generator status monitoring
• Maintenance reminders
• System alerts and notifications
• Remote performance monitoring

This feature helps property owners detect maintenance needs before they become serious mechanical issues.
