The PRS550GF is a 550 kW / 687 kVA industrial diesel generator set engineered to deliver dependable prime power or critical standby backup for heavy industries, infrastructure systems, and large-scale commercial facilities. Built around a proven heavy-duty Shangchai engine platform, this power generation system provides transient response, low fuel consumption, and operational thermal stability in high-ambient environments.
As an export-oriented OEM manufacturer and systems integrator, Probe Power provides comprehensive custom configuration services. We do not supply rigid, off-the-shelf trading products. Instead, we work directly with project contractors, industrial facilities managers, and procurement officers to engineer a power platform tailored to explicit site requirements, electrical loads, and regional compliance standards.
1.Technical Engineering Highlights
Engineered for Critical Multi-Unit Paralleling & Megawatt Systems
The PRS550GF platform is optimized for multi-unit parallel operations, allowing multiple 550 kW sets to link seamlessly into synchronized megawatt-level (MW) utility grids or isolated bus-bar systems. This capability makes it the preferred backup choice for high-availability infrastructure, including:
- Hyperscale Data Centers & Telecom Hubs: Sustaining zero-downtime operations during grid failures.
- Petrochemical & Heavy Industrial Facilities: Supplying high motor-starting currents and process security power.
- Marine Ports & Transport Terminals: Providing rugged power for continuous material handling equipment.
- Municipal Emergency & Command Infrastructure: Delivering reliable black-start capabilities.
High-Performance Shangchai SC27G830D2 Engine Base
Operating at a stable 1500/1800 RPM (50Hz or 60Hz) , this engine delivers a prime power rating of 610 kW and a standby threshold of 665 kW. Featuring a highly efficient PT fuel injection system and a specific fuel consumption profile of 202 g/kW·h, it optimizes operating expenditures (OPEX) over extended runtime cycles.
Advanced System Integration & Traceable Components
Probe Power maintains absolute supply chain transparency. Every PRS550GF unit is integrated with top-tier industrial components to ensure reliable electrical fault protection and localized serviceability:
- Alternator Engineering: Standard with a PRS 100% copper brushless, self-excited alternator (IP22/IP23 protection, H-class insulation). Premium international upgrades including original Stamford, Marathon, or Engga are available.
- Control Systems: Fully integrated digital control panels featuring Deep Sea Electronics (UK), ComAp (Czech Republic), or SmartGen (Zhongzhi) platforms to handle automatic mains failure (AMF), remote monitoring, and automated safety shutdowns.
- Switchgear & Breakers: Equipped with authentic Chint or Delixi circuit breakers to protect against overcurrent, short-circuits, and voltage fluctuations.
2.Technical Specifications
Performance specifications conform to ISO 8528, ISO 3046, and BS 5514 standards. Continuous ratings are applicable under variable load conditions with an overload capability of 10% for 1 hour in every 12 hours of operation.

3.Custom Configuration & Enclosure Options
Every installation site presents distinct environmental constraints. Probe Power offers four specialized modular structural configurations for the 550 kW Shangchai platform:
- Soundproof & Silent Enclosure: Built with heavy-gauge acoustic materials, weather-proof seals, and residential-grade exhaust silencers. It limits operational noise to meet strict municipal or indoor environmental decibel limits.
- Weatherproof Rain Shelter: Provides fundamental protection against rain, UV radiation, and airborne dust for outdoor desert or tropical installations where noise is not a primary constraint.
- Mobile Trailer Chassis: Mounted onto a heavy-duty, multi-axle towed chassis with integrated braking and road lighting, allowing rapid relocation across remote construction sites or mining fields.
- Automatic Transfer Switch (ATS) Cabinets: Configured with wall-mounted or free-standing ATS cabinets for automatic grid-to-generator power migration within seconds of a utility outage.
