125kW Briggs & Stratton Standby Generator - 277/480V, 225A Breaker, 3-Phase, Block Heater & Battery Charger Included - 3-Year Warranty

Briggs & Stratton 125kW Standby Generator – 277/480V Three-Phase LPV Backup Power

The Briggs & Stratton 125kW Standby Generator (Model 080018) delivers enterprise-grade three-phase backup power for warehouses, manufacturing plants, industrial facilities, and large commercial operations running on 277/480V Wye-configured electrical systems. When the grid fails, this unit restores three-phase power within seconds — keeping industrial motors, HVAC systems, compressors, commercial lighting grids, production equipment, and mission-critical infrastructure running without interruption.

Powered by a liquid-cooled, turbocharged PSI 8.8L V-8 engine producing 230 gross horsepower at a steady 1,800 RPM, this generator is built for the most demanding standby applications. Liquid propane vapor (LPV) fuel operation eliminates on-site diesel storage, reduces emissions, and ensures a stable, readily available fuel supply independent of utility gas infrastructure.

DSE 7310 Mk II Smart Controller
The integrated DSE 7310 Mk II controller provides web-based monitoring, RS232/RS485 remote communications, configurable I/O, a 250-event log, load switching, load shedding, integral PLC editor, runtime scheduling, and full power monitoring (kW, kVA, kVAR) — 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 925 CCA starting battery at peak charge — ensuring the system is always primed and ready when you need it most.

Key Specifications

225A Breaker for High-Voltage Three-Phase Industrial Loads
The factory-installed 225A breaker provides robust overload protection and simplified connection to your 277/480V three-phase Wye distribution panel. While the amperage is lower than the 120/208V and 120/240V variants, the higher voltage delivers the same 125kW output — making this configuration the standard choice for industrial facilities, warehouses, farms, and large commercial operations where 277/480V three-phase power is the established infrastructure standard.

The 277/480V Wye configuration supports industrial motors, high-voltage lighting systems, large HVAC equipment, compressors, and other heavy three-phase loads common in manufacturing and industrial environments. The sound-attenuated steel enclosure protects internal components from rain, wind, and harsh outdoor environments, while integral vibration isolation ensures smooth, stable operation. Optional accessories include liquid propane vaporizer kits, remote annunciator kits (DSE 2548-01), remote display modules (DSE 2510-32), emergency stop switches (NEMA 4X), communication interface module (DSE 890-01), AVR communication cable, battery warmer, and battery cable lockout for full installation flexibility.

FAQ

What can the Briggs & Stratton 125kW 080018 generator power?
With 125kW / 188A of three-phase output at 277/480V Wye, this generator is sized for industrial facilities, warehouses, manufacturing plants, and large commercial operations. It simultaneously powers industrial motors, compressors, large HVAC systems, high-voltage lighting grids, production equipment, and other critical three-phase loads during an outage.

Why choose the 277/480V 080018 over the 120/208V 080016 or 120/240V 080017?
All three models deliver the same 125kW output on the same engine platform. The difference is voltage configuration. The 080018 is the right choice for facilities with existing 277/480V three-phase Wye infrastructure — the standard voltage for most industrial and heavy commercial environments. The 080016 suits office buildings and light commercial facilities on 120/208V Wye, and the 080017 serves facilities on 120/240V Delta. Always confirm your facility's electrical configuration with a licensed electrician before ordering.

What fuel type does the 080018 use and what are the supply requirements?
This generator runs on liquid propane vapor (LPV). The fuel supply line inlet is 1-1/2" NPT and requires a supply pressure of 7–11 in H₂O (17–28 mbar). Full-load fuel consumption is approximately 627 ft³/hr (17.8 m³/hr). A liquid propane vaporizer kit is available as an optional accessory for installations sourcing fuel from a bulk LP tank.

Does the Briggs & Stratton 080018 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 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.
