    AC Boards with the CK2 built-in for retrofitted systems with IQ Battery


    This Enphase Distribution Board comes with everything you need to install an existing Enphase system with IQ Battery.  

    The Enphase Communication Kit 2 (CK2) is pre-Installed in the AC Board, which saves you time on-site, avoid wiring issues, and speeds up commissioning.

    Our Enphase AC Board with CK2 accommodates the IQ Gateway and all necessary electrical hardware for retrofitting an existing Enphase system with IQ Batteries. 

    They are fully pre-wired, tested, and customisable to your specific installation needs. They come pre-labeled* along with enough CAN communication cable to run to multiple IQ Batteries.

    *Pre-labeled to meet AS/NZS 5033/4777 requirements, with labels for the main switchboard and battery included.

    About the Enphase CK2


    Matthew Lutz, our Enphase Product Specialist, explains in this short video how the CK2 works and what your installation options are.


    The CK2 acts as a communication converter, enabling direct communication between your IQ Gateway (formerly known as Envoy) and the IQ Battery, without the need for a IQ System Controller.

    The CK2 can reduces the system costs significantly by removing the need for an IQ System Controller in grid-tied mode where backup is not required by the homeowner. This enables you to install more IQ Batteries for more customers (new or existing) using their systems for daytime charging and nighttime discharging, helping you secure more Enphase projects.
