Product Mobile LinkTM

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.
