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 480V 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.
