Featuring first-in-class dual-valve, ultra-low-pressure fuel delivery and intelligent engine controls for more than one hundred performance functions, the Generac RG04845JNAX offer peak efficiency through all temperature ranges and elevations.

True Power Technology ensures utility-grade power. Safe for sensitive electronics—runs appliances and lights—powers heavy duty motors on air conditioners, pumps and shop equipment. All at the same time. Isochronous Frequency regulation within 0.25%, automatic digital voltage regulation to 1%, and less than 5% total harmonic distortion.

The Evolution Controller with 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 48kW Generac 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.

The optional Mobile-Link 4G LTE (sold separately) utilizes the cellular network for reliable communications during outages and natural disasters.

Inside, a durable protective coating prevents rust on the RG04845JNAX 240V Generator frame. Outside, the Rhino-Coat Powder-coated finish on the aluminum cabinet forms a corrosion resistant barrier under the harshest environmental conditions.
