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

          • 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.
          • Wireless Mobile-Link comes standard on the Generac 48kW. Access the generator controller from anywhere in the world on any mobile device, laptop, or desktop computer. 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 48 kW Generac frame. Outside, the Rhino-Coat Powder-coated finish on the aluminum cabinet forms a corrosion resistant barrier under the harshest environmental conditions.

                            On time delivery. Great generator

                            Fast shipping. I have received this unit couple of weeks ago. Since then we have lost the power twice and the generator worked really good. The generator is quiet and provided stable power for my home.

                            Excellent unit

                            Very good generator. Our entire remote job site offices are running on this machine. All of our power tools work without any issues. Better than our old machine. Worth buying this beast.
