Frequently Asked Questions

What is the standby rating of the Hipower HDI-350F?
The HDI-350F is rated at 350 kW standby at 277/480V, three-phase, 60 Hz. It is the highest-output FPT-powered unit in the HDI series and is NFPA 110 Level 1 certified for mission-critical standby applications.
What engine powers the Hipower HDI-350F?
The HDI-350F is powered by an FPT Industrial C13TE3X diesel engine with a Stamford HCI534E alternator. The C13 is FPT's 13-liter industrial diesel, and the HDI-350F represents its maximum standby output in the HDI lineup before the series transitions to Volvo engines at 400 kW.
What are the service intervals for the HDI-350F?
Service intervals are 500 hours for oil changes, air filters, and fuel filters, with a major overhaul at 2,000 hours, consistent with FPT Industrial C13 published maintenance schedules.
How does the HDI-350F compare to Cat, Cummins, or Kohler at 350 kW?
The HDI-350F matches Big 4 certifications — NFPA 110 L1, seismic, 200 mph wind — at the 350 kW class at 15-25% lower list price. As the top of the FPT-powered HDI range, it benefits from a lighter, more compact package than competing designs at this output.
Is the HDI-350F NFPA 110 Level 1 compliant?
Yes. The HDI-350F carries NFPA 110 Level 1 certification with seismic and 200 mph wind ratings, making it eligible for healthcare, data center, and emergency egress standby applications.
