150kW Briggs & Stratton Standby Generator - 277/480V, 250A Breaker, 3-Phase, Block Heater & Battery Charger Included - 3-Year Warranty

Briggs & Stratton 150kW Standby Generator – 277/480V Three-Phase Natural Gas Backup Power The Briggs & Stratton 150kW Standby Generator (Model 080023) delivers enterprise-grade three-phase backup power for warehouses, manufacturing plants, industrial facilities, data centers, 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 running at a steady 1,800 RPM, this 150kW unit brings the largest engine platform in the Briggs & Stratton liquid-cooled lineup to bear on high-voltage three-phase industrial applications. 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 7310 Mk II Smart Controller The integrated DSE 7310 Mk II controller provides web-based monitoring, RS232/RS485 remote communications, configurable inputs/outputs (9/8), CANbus speed sensing, 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.

While the amperage is lower than the 120/208V and 120/240V variants, the higher voltage delivers the same 150kW output — making this the standard configuration for industrial facilities, warehouses, data centers, and large commercial operations where 277/480V three-phase Wye power is the established infrastructure standard. The 277/480V Wye configuration supports the full range of industrial three-phase loads — high-voltage motors, large HVAC equipment, compressors, industrial lighting systems, and heavy production machinery. The premium Galvannealed steel enclosure features acoustic insulation meeting UL 94 HF1 flammability classification, a critical-grade silencer, lockable stainless steel door latches, and hinged doors for easy service access — delivering both weather resistance and reduced noise output at just 77 dB(A) no-load. Integral vibration isolation ensures smooth, stable operation. This unit is rated for NFPA-110, Level 2 applications with appropriate accessories. Optional accessories include remote annunciator kits (DSE 2548-01), remote display module (DSE 2510-32), communication interface (DSE 890-01), AVR communication cable, and emergency stop switches (NEMA 4X). Model: 080023 Warranty: 3-Year Parts, Labor & Travel FAQ What can the Briggs & Stratton 150kW 080023 generator power? With 150kW / 225A of three-phase output at 277/480V Wye, this generator is sized for industrial facilities, warehouses, manufacturing plants, data centers, and large commercial operations. It simultaneously powers high-voltage motors, compressors, large HVAC systems, industrial lighting grids, production equipment, and other critical three-phase loads during an outage — making it the top-capacity option in the Briggs & Stratton 277/480V lineup. Why choose the 277/480V 080023 over the 120/208V 080021 or 120/240V 080022? All three deliver the same 150kW output on the same 8.8L V-8 engine platform. The 080023 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 080021 suits large commercial buildings and data centers on 120/208V Wye, and the 080022 serves facilities on 120/240V Delta. Always confirm your facility's electrical configuration with a licensed electrician before ordering. What fuel type does the 080023 use and what are the supply requirements? This generator runs on natural gas (NG). 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 1,970 ft³/hr (55.8 m³/hr) — verify your utility gas supply capacity can support this demand before installation. Connection to your existing utility gas line eliminates on-site fuel storage entirely. Does the Briggs & Stratton 080023 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.
