Description
Generac’s Mobile Link allows you to check the status of your generator
from anywhere that you have access to an Internet connection from a
PC or with any smart device. You will even be notified when a change in
the generator’s status occurs via e-mail or text message. Note: Harness

Adapter Kit required. Available in the U.S. only.
Harness Adapter Kit
The Harness Adapter Kit is required to make liquid-cooled units compatible with Mobile LinkTM.
Cold Weather Kit
If the temperature regularly falls below 32 °F (0 °C), install a cold weather kit to maintain optimal battery temperature. Kit consists of battery warmer with thermostat built into the wrap.
Extreme Cold Weather Recommended where the temperature regularly falls below 32 °F (0 °C)
Kit
for extended periods of time. For liquid cooled units only.

Paint Kit
If the generator enclosure is scratched or damaged, it is important to touch- up the paint to protect from future corrosion. The paint kit includes the necessary paint to properly maintain or touch-up a generator enclosure.
Scheduled Maintenance Kit
The Liquid-Cooled Scheduled Maintenance Kits offer all the hardware necessary to perform complete maintenance on Generac liquid-cooled generators.
Completely wireless and battery powered, Generac’s wireless remote Local
Wireless Monitor monitor provides you with instant status information without
ever
leaving the house.
Wireless Remote Extension Harness
Recommended for use with the Wireless Remote on units up to 60 kW, required for use on units 70 kW or greater.
Smart Management Module (50 Amps)
Wi-Fi LP Fuel Level Monitor
E-Stop
Smart Management Modules are used in conjunction with the Automatic Transfer
Switch to increase its power management capabilities. It provides additional
power management flexibility not found in any other power management system.
The Wi-Fi enabled LP fuel level monitor provides constant monitoring of the
connected LP fuel tank. Monitoring the LP tank’s fuel level is an important
step in making sure your generator is ready to run during an unexpected power
failure. Status alerts are available through a free application to notify when
your LP tank is in need of a refill.
E-stop allows for immediate fuel shutoff and generator shutdown in the event
of anemergency.
