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

  • Rated output: 60,000 watts
  • 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
  • CARB compliant: Yes
  • Made in USA: Yes
  • Weight: 2020 lbs
  • Dimensions: 98" L x 39.4" W x 43" H
  • Circuit breaker size: 250A

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.

Love this set!!!
Size: Medium (2.5"), Style: Fetch Pack 1
I was trying to figure out which of the many different balls this company offers, and I was getting frustrated but then i was SOOOO happy to see they had multiple sets that had multiple of the different balls they offer!! I bought this set and the other set they offer, but this one was my favorite and I think my dogs too! The orange ball works great and bounces just high enough that it doesn’t clear our patio wall, but enough for him to go and jump up to retrieve. But the glow in the dark ball is his favorite! Both me and my pomsky were blown away how we brought the glow in the dark ball outside just as the sun was going down, and when we brought it back inside it was BRIGHT AND GLOWY!!! Even with the sun going down and not much light left!! He loves to play with it in the house after it’s all glowy from the sun. Sometimes we even glow it up under a light inside the house if it’s dark outside, and he will play with it outside in the dark haha he loves it!!! And I think it’s pretty cool too!! All of the balls this company overs are VERY durable! We realized early on that we cannot give our dog regular tennis balls cuz his favorite thing to do is tear the outside fabric off!! So we were trying to figure out what company has the best balls for dogs so they can’t sit there and try to pry them apart, and we found this company!! We have already bought from them about 3 times and all of their balls are durable and bounce how they say they will bounce!! They have the super bouncers and the glow in the dark one and the one with angles that will bounce in different directions and the ones you can throw REALLYY far! Overall, all the balls from this company are very durable, bounce really good, and keep my dog occupied without allowing him to sit there and tear it apart!!! Which i love cuz I do not like when he stops playing with us to sit there and try to take off the fabric, cuz then he could swallow it! So always buy the balls from this company!!! They are the best and most durable!!!! Also plenty soft for your dogs mouth so they can chew on it a bit and it won’t hurt their teeth/gums!

Good sturdy balls
Size: Medium (2.5"), Style: Fetch Pack 2
My dogs love balls! Unfortunately, they tend to chew them up very quickly. My Belgium Malinois chews on this all the time, and it has held up pretty well. Good option for chewers

Fetch Perfection
Size: Medium (2.5"), Style: Fetch Pack 2
If you’re anything like me, fetch is the ultimate game with your furry companion. The Chuckit! Dog Fetch Ball Medley has taken our playtime to the next level with its variety and durability. This 3-pack of medium-sized, ultra-rugged balls is perfect for endless games of fetch without worrying about wear and tear. I love how each ball has a unique texture and color, keeping my dog engaged and excited every time. The medium size is just right for energetic dogs, allowing for long throws and big leaps. Plus, the rugged design means these balls can withstand even the most enthusiastic chewers and rough play sessions, making them a great investment for active pets. However, the vibrant colors can sometimes make them easy to lose in green grass or sandy beaches, but a good game of hide-and-seek with your dog is a small price to pay for such fantastic fetch balls. Additionally, while they’re durable, no ball is completely indestructible, so occasional replacements might be necessary for the most aggressive players. Overall, the Chuckit! Dog Fetch Ball Medley is a must-have for any dog owner looking to enhance their playtime. They’re fun, durable, and keep both you and your dog entertained for hours. A solid 5-star rating for their quality and variety, with a tiny star lost to their occasionally elusive colors.

great ball!
Size: Medium (2.5"), Style: Fetch Pack 2
My pitbull LOVES these. She is a power chewer and tough on balls and toys and tends to go through them insanely quick. She is still on her first ball out of this pack and its been at least two months. It is a little small for her mouth but she doesn’t seem to mind, as it has quickly become one of her favorites. Not a loud ball and it doesn’t usually make that wet chewy noise when shes going to town on it which is huge for me😂😂 Safe for my pittie so i’d imagine a smaller dog would be just fine.

Border Collie Approved: Easy to Clean, Durable, and Great Bounce
Size: Medium (2.5"), Style: Fetch Pack 2
These are the best balls out there for dogs. These fit great in the chuck-it ball launcher, which we need to wear out my border collie. They fit her mouth properly and, most importantly, do not absorb all the spit or water after a good rain. They are quick to clean off and have good weight so you can let them fly! Furthermore, they bounce well, which is perfect for my dog that likes to catch them on a bounce. The ball is a strong rubber, so should not be easy to chew up. I've used these for years, and the only time I've had to replace them is when one gets lost in the hay field. I highly suggest these as replacements for the common tennis balls.
