ENSEMBLE COMMUNICATIONS KIT 2

The Communications Kit 2 enables communication between IQ Gateway, IQ Battery 5P, and
IQ System Controller 3/3G. The Communications Kit 2 cannot be used with prior versions of the
IQ Battery or the IQ System Controller. The Communications Kit 2 can be used to upgrade PV-only
sites to grid-tied or grid-forming systems in the absence of an IQ Combiner 5/5C. It is not needed
when an IQ Combiner 5/5C is used because the IQ Combiner 5/5C integrates the functionality of
the Communications Kit 2.

Enphase Communications Kit - Enables wired communications using Control cables for systems not using IQ Combiner 5/5C.
