• Enphase Wireless communication kit enables direct communication between IQ Battery, IQ System Controller,
and the Gateway using 2.4 GHz frequency. The kit is connected to one of the USB ports on the IQ Gateway.
• An Enphase Mobile Connect™ cellular modem is required unless already present to ensure the best performance
of your system. The cellular modem connects to a USB port on the IQ Gateway.
• For new or retrofit systems with IQ-Series solar microinverters:
o IQ8 PV
TM
(IQ8/ IQ8Plus /IQ8M /IQ8A /IQ8H-240) series microinverters and accessories. Enphase
Energy System technology is fully compatible with IQ8 series microinverters
o IQ Gateway™, a communications gateway that can communicate with IQ8 series Microinverters, IQ
batteries, and the IQ System Controller smart switch. It collects system performance information and
transmits that information over the internet to Enphase’s cloud. An IQ Gateway is required for Enphase
Energy systems with IQ-Series microinverters. Note the IQ Gateway is included in an Enphase IQ
Combiner.
o IQ™ Combiner series consolidates interconnection equipment into a single enclosure and
streamlines PV and storage installations by providing a consistent, pre-wired solution for residential
applications. It includes the Enphase IQ Gateway. Install the new communication kit in any IQ Combiner to
enable wireless communication with Enphase IQ Battery and IQ System Controller
