Generac Protector Series 25kW - Premium Liquid-Cooled Power
1.5L DOHC Engine. True Power™ Quality. Large Residential & Commercial Ready.
The Generac Protector Series 25kW (RG02515ANSX) is engineered to meet the high-demand power needs of large residential estates and light commercial applications. Unlike standard air-cooled models, this unit features a 1.5L liquid-cooled 4-cylinder engine, providing superior thermal management for long-duration operation. With True Power™ Technology delivering ultra-clean electricity (<5% THD), your sensitive office equipment and high-end home electronics are always safe.
Superior Reliability & Advanced Control
At the core of the Protector Series is the Evolution™ Controller, featuring a multilingual LCD display that makes monitoring battery health and maintenance schedules effortless. Designed for versatility, this generator operates on both Natural Gas (NG) and Liquid Propane (LP). Its Quiet-Test™ mode allows the generator to run its weekly self-test at a significantly lower RPM, ensuring your neighborhood remains peaceful with noise levels as low as 59 dB.
Industrial-Grade Protection
Equipped with automatic shutdown protection for high coolant temperature, low oil pressure, and overspeed to ensure the longevity of your investment.
Mobile Link™ Ready
Compatible with Mobile Link™ accessories, allowing you to check your generator's status in real-time via smartphone, tablet, or PC from anywhere in the world.
