IQ Combiner

In stock

This kit provides all necessary equipment to complete interconnection for a new solar installation using home internet connectivity. It includes an Enphase IQ-Combiner-3™ and a pair of consumption monitoring Current Transformers(CTs). Enphase IQ-Combiner-3™ consists of Enphase IQ Envoy™ PCB and a pair of production CTs. The combiner box consolidates interconnection equipment into a single enclosure and streamlines PV and storage installations by providing a consistent, prewired solution for residential application. The combiner box and the current transformers work together with one-another to give full insight into production and consumption data. The CTs enable whole-home consumption metering with an accuracy of +/- 2.5%.


  • Smart - Includes IQ Envoy for communication and control. Flexible networking supports Wi-Fi, Ethernet or cellular. Provides production metering and optional consumption monitoring. Supports installation of the Enphase Q Aggregator.
  • Simple - Eaton BR series panel board interior. Up to four 2-pole branch circuits for 240 VAC plug-in breakers (not included). 80 A total PV or storage branch circuits.
  • Reliable - Durable NRTL-certified NEMA type 3R enclosure. Five-year warranty. UL listed
