The Hipower HNG-160 is a 159 kW stationary natural gas standby generator — the entry point of Hipower's HNG series, which covers the 160–400 kW range above the HGM series' 150 kW ceiling. Built in Olathe, Kansas, the HNG-160 is CARB certified for California natural gas standby applications.
At 159 kW, the HNG-160 serves commercial office buildings, healthcare facilities, and light-industrial operations where natural gas is established and diesel standby would require a large storage tank with SPCC compliance. The unit supports 347/600V in addition to 120/208V and 277/480V, providing flexibility for facilities with high-voltage distribution.
CARB certification enables California permit-by-rule — standard air district approval without source test or variance. For California facilities in the 150–200 kW range, the HNG-160 provides a CARB-certified natural gas option that eliminates diesel fuel compliance obligations.
The HNG-160 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 for this output range 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.
Hipower's HNG series holds CARB certification for California natural gas stationary standby. The HNG-160 qualifies for California permit-by-rule, enabling standard air district approval.
OnPoint Generators maintains natural gas standby generators throughout Northern California. The HNG-160 is appropriate for commercial and light-industrial buildings where the existing gas infrastructure supports standby without requiring a separate diesel fuel system.

Estimate runtime on this tank
Fuel demand at 75% load
1,669,500 BTU/hr≈ 1669.5 cf/min @ 1,000 BTU/cf
On utility natural gas the runtime is generally unlimited provided the supply line and meter can deliver this BTU/hr at the engine's required inlet pressure (typically 5–14" WC residential, up to 5 psi commercial). Confirm against the OEM's published fuel-pressure spec.

Frequently Asked Questions
What is the HNG series?
The HNG is Hipower's larger stationary natural gas generator series, covering 160–400 kW. It picks up where the HGM series tops out at 150 kW, providing CARB-certified natural gas standby for larger commercial and industrial facilities.
What engine does the HNG-160 use?
The HNG-160 uses a PSI natural gas engine. PSI is Hipower's engine supplier for the HNG stationary series above 100 kW. The specific PSI model designation for this output range is pending verification from OEM documentation.
Is the HNG-160 CARB certified?
Yes. Hipower's HNG natural gas series holds CARB certification for California stationary standby applications.
What voltage options are available?
The HNG-160 supports 120/208V, 277/480V, and 347/600V — the 600V option is useful for Canadian-standard installations or US facilities with 600V distribution.
What applications is the HNG-160 suited for?
Commercial office buildings, industrial facilities, and healthcare outpatient centers in the 150–200 kW range where natural gas service is established and CARB certification is required.
Who services HNG units in Northern California?
OnPoint Generators provides service for Hipower natural gas generators, including HNG series units, throughout Northern California.
