150 kW Generac Generator

Generac designs and manufactures the Protector Series 150 kW 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 RG15090AVAC with 9 Liter Turbocharged and Aftercooled V-8 engine was designed and built by Generac in USA facilities located in Wisconsin. The engine features hydraulic roller lifters and a gear-driven oil pump for full-pressure lubrication. Generac’s engine provides peak efficiency through all temperature ranges and elevations.

True Power Technology—Utility-Grade Power safe for sensitive electronics. 150 kW of backup power for office equipment, 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.)

The 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 Generator in top condition and ready for the next power outage.

Generac’s proprietary Quiet-Test self-test mode runs the 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.

WiFi connectivity included. Access the generator controller from anywhere in the world on any mobile device, laptop, or desktop computer. Mobile-Link 4G LTE (sold separately) utilizes the cellular network for reliable communications during outages and natural disasters when WiFi internet connections fail.

Inside, a durable protective coating prevents rust on steel frame. Outside, the Rhino-Coat Powder-coated finish on the aluminum cabinet forms a corrosion resistant barrier under the harshest environmental conditions.

The Protector Series Generac 150kW Generator comes with a standard 5-year limited consumer warranty. Norwall offers extended warranty options on all Generac Generators.
