Overview#
The Hipower HRNG-300 is a 235 kW trailer-mounted natural gas generator in Hipower's HRNG mobile series. At 235 kW, this unit handles large temporary power applications: mid-large commercial buildings during electrical maintenance, active construction sites with high-capacity gas service, stadium events, and data centers requiring temporary power during critical infrastructure work.
The HRNG-300 connects to the site's permanent natural gas supply — no on-board fuel, no diesel delivery, no fuel spill risk. Runtime is unlimited while gas supply is maintained. For construction rentals in the 30–90 day range, this eliminates the fuel replenishment logistics that diesel trailer generators require.
CARB certification enables California temporary standby without air district variance. In California markets where diesel towable regulations are tightening, the HRNG-300 provides a compliant mid-large temporary power option for sites with natural gas service.
PSI Engine Platform#
The HRNG-300 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-300 qualifies for California permit-by-rule.
