Generac RG15089KNAC – 150/120kW Liquid-Cooled Standby Generator

The Generac RG15089KNAC is a gaseous, liquid-cooled automatic standby generator designed for properly planned high-capacity backup power applications using 480/277V 3-phase service. This model is rated for 150kW on natural gas and 120kW on vapor propane, giving property owners and commercial facilities fuel flexibility when professionally installed and properly sized. It is powered by a Generac 8.9L 8-cylinder turbocharged and aftercooled engine with Electronic Fuel Ignition Control technology. This model is listed with a catalyst-equipped emissions configuration; state, local, and project-specific emissions requirements should be verified before purchase or installation. Power Zone 410 control and remote monitoring support are listed in the supplied product data for system visibility and service planning.

150/120kW Backup Power for 480/277V 3-Phase Applications

The RG15089KNAC is intended for larger standby power projects where 3-phase electrical service, high output, and fuel planning are required. Final load sizing, voltage requirements, fuel setup, emissions requirements, transfer equipment, permitting, and site conditions should be confirmed by a qualified installer before purchase or installation.

Natural Gas and Vapor Propane Fuel Support

This model is rated at 150kW using natural gas and 120kW using vapor propane. Fuel availability, gas pressure, fuel line sizing, installation requirements, and local code compliance should be reviewed as part of the project planning process.

8.9L Turbocharged Engine with EFIC Technology

The Generac 8.9L 8-cylinder turbocharged and aftercooled engine uses Electronic Fuel Ignition Control technology for supported gaseous standby generator operation. The 1800RPM operating speed and low-speed exercise cycle should be reviewed with the official documentation and installer during project planning.

Power Zone 410 Controller and Monitoring Support

The Power Zone 410 controller is listed in the supplied product data for this model. Remote monitoring features should be confirmed against the official specification sheet, subscription requirements, network requirements, and final configuration before purchase.

The Generac RG15089KNAC is designed for permanent standby generator applications where high-capacity backup power, 3-phase voltage, and professional installation planning are required. Its 150/120kW output profile should be matched to the property’s electrical service, fuel setup, and backup load requirements.

With natural gas and vapor propane fuel support, Power Zone 410 control, and listed monitoring support, this generator is intended for professionally planned standby power systems. Verify emissions compliance, transfer equipment, fuel setup, and electrical configuration before ordering.
