Why Buy From Us
Briggs and Stratton 60 kW Fortress Standby Generator
Automatically starts in seconds when utility power is lost (Requires Automatic Transfer Switch)
When you are backing up a large home, light commercial building, or critical loads that cannot go down, a small air-cooled standby unit is not the right tool. The Briggs and Stratton 60 kW Fortress is a liquid-cooled, emergency-grade standby generator built to deliver serious, steady power with quieter operation, clean output for electronics, and the kind of warranty that actually helps you sleep at night.
This is the “lights stay on, business keeps running” solution, powered by a 5.7L V8 at 1800 RPM, configured for natural gas or propane (LP), and housed in a corrosion-resistant aluminum enclosure designed for real weather.
Why the Fortress 60 kW is the right generator when you cannot compromise
Starts automatically within seconds
The whole point of a standby generator is that you do not have to be there. With the required automatic transfer switch (ATS) installed, the system:
- Detects utility power loss
- Starts the generator automatically
- Transfers the building to generator power within seconds
- Transfers back when utility power is restored
No cords. No scrambling. No “did it start?” moments.
Liquid-cooled V8 power at 1800 RPM
At the heart of this system is a 5.7L 8-cylinder liquid-cooled engine designed to run smoother and more efficiently than high-RPM units.
What 1800 RPM gets you in the real world:
- Better long-run durability compared to many 3600 RPM designs
- Fuel-efficient operation for its class
- Quieter sound profile for a high-output standby unit
Natural gas or propane configured
Connect to:
- Your home’s natural gas line, or
- A properly sized LP tank
That means no gasoline storage headaches and no refueling in the middle of a storm. Your runtime depends on your fuel supply and load, but the Fortress platform is built for true standby convenience.
Industry-leading warranty coverage
6-Year Parts, Labor and Travel Warranty (consumer)
This is a major differentiator. It is built to reduce the “what if it breaks and I’m on my own” worry that comes with big equipment.
Commercial warranty: 2 years.
Clean, stable power for modern electronics
Today’s homes and buildings run on sensitive electronics. This unit features a computer-friendly brushless alternator with automatic voltage regulation, giving you stable power for:
- Network gear, modems, routers
- Computers and office equipment
- Security systems and controls
- Modern HVAC boards and smart appliances
If you have a home full of electronics, power quality matters as much as wattage.
Smart controls that make ownership easier
The Briggs and Stratton AMF Controller (UL Recognized) gives you clear visibility into what the generator is doing and why.
You get:
- Easy-to-read alpha-numeric scrolling display
- Diagnostic monitoring and fault codes
- Simple weekly exercise-cycle scheduling
This is the stuff that prevents surprises. If there is an issue, you see it quickly. If you want it to self-test weekly, you can set it once and move on.
Built for harsh weather and easier service
Corrosion-resistant aluminum enclosure
An aluminum enclosure helps protect the generator in extreme climates, including wet, coastal, and storm-prone areas.
Convenient service access points
Maintenance should not require unnecessary disassembly. The Fortress design includes service access points to reduce service time and hassle.
Pre-installed block heater
Cold starts are where a lot of standby systems struggle. The pre-installed block heater supports easier cold-weather starting and more consistent performance.
Turnkey extras included
This unit includes the extras you want already integrated:
- Automatic battery charger
- Hour meter
Less piecing together. More “installed and ready.”
Output and performance highlights

- Voltage: 120/240V single-phase
- Frequency: 60 Hz
- Rated amps: 250A
- Noise level: 68 dB at 7m
- NG power capacity: 55,000W
- LP power capacity: 60,000W
- Cooling: Liquid-cooled
- Enclosure: Aluminum
- UL listed: Yes

Fuel consumption:
Natural Gas
- 50% load: 561 ft³/hr
- 100% load: 753 ft³/hr
Propane (LP)
- 50% load: 7.03 gal/hr
- 100% load: 9.56 gal/hr
These numbers matter for planning. Gas line sizing and LP tank sizing should be handled correctly during design and installation so the generator can deliver full output without fuel starvation.
Requirements and install notes (important)
- Automatic Transfer Switch: Required, not included
- Starting battery: Requires 775 CCA battery, not included
- Mounting pad: Concrete pad required, not included
This is a heavy, high-output standby unit. Professional installation is the norm for safety, code compliance, and performance.
Best fit applications
The 60 kW Fortress is ideal for:
- Large homes with substantial electrical demand
- Light commercial buildings
- Farms and ranches with critical infrastructure
- Facilities that need reliable emergency-grade backup power
If you are backing up HVAC, refrigeration, well systems, security, office operations, or critical equipment, 60 kW gives you the headroom that smaller standby units cannot.
Bottom line
The Briggs and Stratton 60 kW Fortress Standby Generator is built for people who want automatic backup power with commercial-grade stability, clean output for electronics, and long-term confidence supported by an industry-leading 6-year parts, labor, and travel warranty.
If you are building a serious standby system, this is the kind of generator you install once and rely on for years.
