Overview#
The Hipower HNI-250 is a 250 kW standby natural gas generator powered by the PSI 13LT — PSI's turbocharged 13-liter spark-ignited platform. This engine family steps up from the V8 architecture used in smaller HNI models, providing additional displacement and torque for the demands of large commercial and industrial standby.
At 250 kW, the HNI-250 is positioned for mid-large office buildings, medical facilities, manufacturing plants, and data centers where natural gas service is established and diesel standby adds operational complexity. CARB certification positions the HNI series — including the HNI-250 — for California projects where non-certified engines require additional regulatory steps.
Engine Platform#
The PSI 13LT is a large-displacement turbocharged spark-ignited engine running at 1800 RPM. PSI's 13-liter platform is purpose-built for stationary standby and prime power applications, with a service history across multiple generator OEMs. No DPF, no DEF, no diesel fuel filtration — maintenance centers on spark plugs, oil changes, and gas system inspection.
CARB-Certified for California#
The HNI series holds CARB certification across 30–1000 kW. The HNI-250 qualifies for California permit-by-rule, which is a meaningful advantage in the 250 kW class where CARB-certified natural gas options from non-Big-4 manufacturers are limited.
Service and Maintenance#
- Oil and filter: 1000 hours or 12 months
- Spark plugs: 1000 hours
- Air filter: 500 hours
- Gas line and regulator: Annual inspection
- Ignition system: Annual inspection
- Major overhaul: 30,000 hours
Our Service Experience#
OnPoint Generators services natural gas generators throughout Northern California, including units in the 250 kW range for commercial and data center applications. Natural gas supply from the utility eliminates diesel storage compliance and fuel delivery logistics — a significant operational advantage for facilities where on-site fuel management adds cost and risk.
