Comes standard with all Protector Series generators. Mobile Link allows you to monitor the status of your generator from anywhere in the world using a smartphone, tablet or PC.

Additional Features
Improved stub ups and electrical connection access decrease installation costs. All connections are dual conductor rated, and the implementation of quick connects for the control wires, completely eliminates the need for crimping or lugging.

Rated 5 out of 5 by JFCH from 38KW Generator - glad with my choice! Very satisified with the 38KW generator bought - and was amazed on how "quiet" it is when turned on (the noise level is way lower than for smaler generators).

Rated 5 out of 5 by Diane89 from This generator has great features! We love this Generac generator. This unit is model RG03824ANAX. While in the test run we noticed is it a bit quieter than the one we had at our previous home. This on is liquid cooled which we were told it would be able to run longer without any problems. Our weather here we have had two instances where we were out of power for 10-12 hours. Looking forward to be ready for the winter!

Rated 5 out of 5 by HappyHome38 from Compact and quiet running We are impressed with the size and how quiet in runs. With only what we saw at other residences, we thought our 38K generator would be much bigger and louder. And, when it arrived, we were surprised at the compact size and how quiet it runs. We do love the app and see it helping us keep up with the weekly exercise routine and maintenance. Really cool unit !

Rated 5 out of 5 by Nicolette9 from Quiet generator Our Generac Supercenter generator is the only one that our HOA will accept due to the fact that it is very quiet.

Rated 4 out of 5 by George from Missing feature The machine seems well built and the installation was smooth but there is an important feature missing. I have a Kohler generator at another location and when it exercises weekly it also takes the full load at the transfer switch and then switches back to normal mode automatically before it runs its cool down cycle. This is a valuable feature as it really tests the whole system weekly, but the Generac cannot perform that and requires a manual override of the transfer switch so it cannot run an acutal full system test. Very disappointed!

Rated 4 out of 5 by RanchMan from Core product great Mobile Link not so great This is my second Generator purchase from Generac. For both generators I purchased the Mobile Link option. My experience with the Generators was exceptional. When it comes to Mobile Link the product never seems to reach maturity. There are now 2 Mobile Link products and during setup no one in support seemed clear on which I should be using. They were also unclear on which mobile link options came with my generator. The support team was convinced I did not have the WiFi option but I did. The rep that spent time with me stuck with it to get me going but it was clear there is a lack of training on the product, unclear information on generator configuration and a number of bugs in the application. I received a message that my account issue had been resolved but no other information. As of the writing of this review all of my issues except mis-reported maintenance history have been resolved but it seems my ticket was closed for some other unknown issue.
