Q: Will this unit work with the 25kW liquid cooled generator?
by Jon from Texas on February 08, 2011

A: The Advanced Wireless Monitor will work with Generac Air Cooled and Liquid Cooled standby models that have the Nexus controller.

There is a Harness Adapter required for 22 - 60kW Liquid Cooled models.
