Mobile Link is the optional cellular remote monitoring system from Generac that allows you to check your generator’s status from anywhere in the world using your computer, tablet or smartphone.

Rated 3 out of 5 by from Good, but.. The installation all went according to plan and the guys did a great job wiring and connecting the system to my house. The start-up worked great in manual mode, but when we went to test under power outage simulation the engine cranked but never started. I am awaiting a technician to install the remote monitoring and fix the generator. I suspect that the control board is defective. Was this factory tested?? This is my 3rd Generac generator and I have always recommended this brand.

Rated 5 out of 5 by from Worked better than expected We chose to go with a 27kW whole house system as everything is electric and we live in a rural area. Nothing worse than sitting in the dark with no heat & water and no knowledge of when hydro will be back on line. With climate change we are experiencing more wind events thus more power outages and this propane fueled generator fires right up giving us a huge sense of safety & comfort.

Rated 5 out of 5 by from Mobile Link was an important feature Replacing a 15 year old Generac unit still in good condition. But being able to monitor it remotely was important to us. Also replaced with a similar unit at my Mother-in-laws. The installer did an excellent job.
