GENERAC RG08045GNAX Protector 80kW Automatic Standby Generator 120/208 3Ø

That's exactly what this unit is built for. The RG08045GNAX Protector is a 120/208V three-phase machine rated at 80kW (80,000 watts), with a 200 A current rating. It is not a single-phase unit and it won't serve a 120/240 single-phase panel. If your building service is 277/480 three-phase or single-phase, you need a different voltage configuration in the Protector line.

Plan the pad around a footprint of 97 in long by 38 in wide, with the enclosure standing 49 in tall. The Protector line is approved for an 18 in offset, so it can sit just 18 inches from the structure, which is what makes it workable on tight lot lines or narrow side yards. Add clearance in front of the control panel and doors for service access.

The Protector 80kW carries UL Listing, ETL Listing, and CSA Certification. That covers the approvals most commercial and institutional inspectors ask for on a permanently installed standby set. Note the unit is flagged with shipping restrictions, so confirm handling requirements for your jurisdiction before scheduling.

The RG08045GNAX is the generator unit itself. A transfer switch is sized and ordered separately, and it has to match the 120/208V three-phase service and the amperage of the load you're backing up. The generator is rated at 200 A, so spec the switch against your service and the portion of the panel being transferred.

Generac's True Power technology on the Protector Series holds total harmonic distortion under 5 percent, which is utility-grade quality. That's the threshold typically cited for running IT gear, medical equipment, and VFDs without additional conditioning. It also starts large motor loads, so rooftop AC and process equipment come online without the sag you get from a weaker set.

Mobile Link connectivity is standard on every Protector Series unit, so status and alerts come through a phone, tablet, or PC from anywhere. For a portfolio with generators at several sites, that means exercise results and fault conditions land with your team instead of waiting for a site visit. The Evolution controller also carries an LCD readable from outside the enclosure, with maintenance interval tracking, so a tech can check status without opening the doors.

The purpose-built Generac engine uses a dual-valve ultra-low pressure fuel delivery system with proprietary engine controls that hold efficiency across temperature and elevation ranges. Generac states these engines consume up to 25 percent less fuel than competitive engines, which matters on a liquid-cooled 80kW set where an extended outage burns real money. Have your gas contractor verify supply line sizing and pressure at the unit before startup.

Order it as Generac RG08045GNAX. That designation is the 80kW Protector Series liquid-cooled standby set configured for 120/208V three-phase. Adjacent Protector models cover different kW ratings and voltage configurations, so the full suffix matters when you're matching a spec on the drawing.

The enclosure is all-aluminum with Generac's RhinoCoat powder-coated finish, so there is no steel shell to rust through. Aluminum framing plus powder coat is the configuration you want in salt air or near pool chemistry. Standard color is Bisque, a neutral tone meant to sit quietly against landscaping.

Quiet-Test self-test mode runs the engine at a reduced RPM for either five or twelve minutes, which keeps the exercise noticeably quieter and burns less fuel than a full-speed run. You can program it weekly, bi-weekly, or monthly, so an 80kW set behind an occupied building can be scheduled around tenant hours.

Country of origin is the United States. Generac states the Protector Series generators and their engines are engineered and built in the USA, with the engine purpose-built in Wisconsin. That is the documentation starting point for a government or institutional buyer working a domestic-content requirement.
