The Generac 80 kW Generator brings best-in-class backup power for small business, retail locations, and agricultural operations. The three-phase 120/208-volt 80kW generator with True Power Technology provides clean, smooth power utility-quality power with less than 5% Total Harmonic Distortion (THD)

Business offices, small retail, and agricultural application stay open and continue work without interruption during outages with 80 kW Generator Power. Leave power-outage worries behind with a Natural Gas or LP Propane powered Generac Protector 80kW Generator.

The Generac RG00845AGAC Meets EPA, California, and Massachusetts  Emissions Standards. For sale in all 50 states.

80kW Generator

Generac designs and manufactures the Protector Series 80kW Standby Generator in Wisconsin. Trained, knowledgeable staff at the Customer Care center near the Milwaukee headquarters answer questions 24 hours a day, seven days a week, 365 days a year.

Made in the USA—The RG08045GNAC with a turbo-charged and aftercooled inline 4-cylinder 4.5-liter engine was designed and built in USA facilities located in Wisconsin. The engine features hydraulic lifters and a gear-driven oil pump for full-pressure lubrication. This purpose-built Generac engine provides peak efficiency through all temperature ranges and elevations. The generator is configured at the factory to run on natural gas and converts easily to LP Propane in the field.

Utility-Grade Power—True Power Technology means safe for sensitive electronics. 80 kW generator power for computers, electronics, appliances, lights, heavy duty motors on air conditioners and refrigeration equipment—all at the same time. Isochronous Frequency regulation within 0.25% and Automatic digital voltage regulation (AVR) to 1%. Less than 5% THD (total harmonic distortion.)

Generac’s Digital Evolution Controller with two-line multilingual LCD display is smart, user-friendly, and viewable without opening the generator cabinet. Monitor generator performance, review status logs, and track maintenance to keep your 80 kW Generac Generator in top condition and ready for the next power outage.

Proprietary Quiet-Test self-test mode runs the Generac 80kW generator at a lower speed during a five or twelve-minute self-test while it performs diagnostics and exercises the generator. Program regular exercise at weekly, bi-weekly, or monthly intervals to ensure the generator is always ready to protect your home or business from an outage.

Protector Series Generators come equipped with Mobile Link Connectivity. Monitor generator status from anywhere with a smartphone, tablet, or PC. Access status and maintenance alerts. Connect with authorized service dealers for fast, proactive service.

A durable protective coating prevents rust on steel frame inside the aluminum generator cabinet. Outside, the Rhino-Coat Powder-coated finish adds a corrosion-resistant barrier in the harshest environments.

The 120/208-Volt Three-Phase Protector Series Generac 80 kW Generator comes with a standard 5-year limited warranty. Norwall offers extended warranty options on all Generac 80kW Generator Models.
