Briggs & Stratton 80kW Standby Generator – 120/240V Single-Phase Natural Gas Backup Power
The Briggs & Stratton 80kW Standby Generator (Model 080080) delivers dependable, high-capacity backup power for businesses, large commercial properties, and luxury homes with single-phase electrical systems. When the grid fails, this unit restores 120/240V single-phase power within seconds — keeping HVAC systems, refrigeration, lighting, security systems, and critical equipment running without interruption.
Powered by a liquid-cooled, turbocharged PSI 5.7L V-8 engine running at a steady 1,800 RPM, this generator is built for long-life reliability under heavy loads and extended run cycles. Natural gas operation connects directly to your existing utility supply — no on-site fuel storage, no refueling, and no interruptions to your fuel source during an extended outage.
DSE 4520 Mk II Controller
The integrated DSE 4520 Mk II controller provides true three-phase generator sensing, power monitoring (kW, kVA, kVAR), RS232/RS485 remote communications, configurable inputs/outputs, CAN sensing, heated display option, power save mode, and the DSE Configuration Suite PC software — giving facility managers and electrical contractors complete operational visibility and control from on-site or remotely.
Block Heater & Battery Charger Included
Both accessories come standard. The block heater maintains engine temperature for reliable cold-weather starts, while the Marinco 6-amp battery charger keeps the 630 CCA starting battery at peak charge — ensuring the system is always primed and ready when you need it most.

FAQ
What can the Briggs & Stratton 80kW 080080 generator power?
With 80kW / 333A of single-phase output, this generator is sized to power large commercial facilities and luxury homes. It supports HVAC systems, commercial refrigeration, lighting, servers, security systems, elevators, and other critical single-phase electrical loads simultaneously during an outage.
What fuel type does the 080080 use and what are the supply requirements?
This generator runs on natural gas (NG). The fuel supply line inlet is 1-1/4" NPT and requires a supply pressure of 7–11 in H₂O (17–28 mbar). Full-load fuel consumption is approximately 1,259 ft³/hr. Connection to your existing utility gas line eliminates the need for on-site fuel storage.
Does the Briggs & Stratton 080080 include an automatic transfer switch?
An automatic transfer switch (ATS) is not included but is available separately. When paired with a compatible ATS, this generator activates automatically within seconds of detecting a utility power failure — with no manual intervention required.
What is included in the box?
The 080080 includes the generator unit with Galvannealed steel enclosure, DSE 4520 Mk II controller, block heater, Marinco 6-amp battery charger, battery with rack and cables, electronic isochronous governor, complete gas fuel system (fuel mixer, electronic secondary gas regulator, gas solenoid valve, and flexible fuel line), integral vibration isolation, and operation and installation literature.
What does the 3-year warranty cover?
The Briggs & Stratton 3-year limited warranty covers parts, labor, and travel for domestic installations. The engine carries the same 3-year coverage. Enclosure surface rust and corrosion are covered for 1 year; rust-through is covered for 2 years. See the operator's manual or BRIGGSandSTRATTON.com for complete warranty terms.
