Overview#
The Hipower HRNG-510 is a 408 kW trailer-mounted natural gas generator in Hipower's HRNG mobile series — the mid-large model in the lineup before the 700 kVA and 900 kVA units. At 408 kW, this is a large temporary power platform suited for hospital bypass, industrial outage coverage, and major construction projects with high-capacity gas service.
HRNG units connect to the site's permanent natural gas supply — no on-board fuel, no diesel delivery logistics, and no SPCC compliance. At 408 kW, gas supply engineering is a critical deployment prerequisite: the site's meter capacity, regulator sizing, and piping must be confirmed adequate before the unit is deployed.
CARB certification makes the HRNG-510 suitable for California temporary standby without air district variance. For California industrial and commercial markets where diesel regulations are tightening, the HRNG-510 provides a high-capacity CARB-certified alternative for gas-served sites.
PSI Engine Platform#
The HRNG-510 is powered by a PSI natural gas engine running at 1800 RPM. PSI supplies spark-ignited engines to multiple standby generator manufacturers and maintains a broad parts and service network across North America. The specific PSI model designation for this output class is pending verification from OEM documentation — service follows standard PSI spark-ignited practice: spark plugs and oil at 1000-hour intervals, annual gas system inspection, no DPF, no DEF.
CARB-Certified for California#
Hipower's HRNG series holds CARB certification for California temporary natural gas standby. The HRNG-510 qualifies for California permit-by-rule.
Service and Maintenance#
- Oil and filter: 1000 hours or 12 months
- Spark plugs: 1000 hours
- Air filter: 500 hours

Our Service Experience#
OnPoint Generators supports HRNG natural gas trailer generators throughout Northern California. The HRNG-510 is appropriate for large industrial and commercial temporary power applications where sites have permanent gas service and diesel logistics at this scale are operationally impractical.
