Enphase IQ Combiner 4 X-IQ-AM1-240-4

The Enphase IQ Combiner 4, designed for compatibility with IQ8 microinverters, integrates interconnection equipment into a singular enclosure, thereby streamlining installations for photovoltaic (PV) systems and energy storage. By offering a consistent, pre-wired solution, it enhances operational efficiency. The unit accommodates up to four 2-pole input circuits, though breakers are not included, and features an Eaton BR series busbar assembly.

At the heart of the system is the IQ Envoy, which enables communication and includes two consumption current transformers (CTs) for monitoring energy use. Users benefit from versatile networking options as the Enphase IQ Combiner supports connections via Wi-Fi, Ethernet, or cellular networks. It not only provides production metering but also offers optional consumption monitoring capabilities.

Additionally, this combiner allows for the installation of the Enphase Q Aggregator, ensuring broader operational flexibility. The interior is built upon the Eaton BR series panel board, situated within a robust, NRTL-certified NEMA type 3R enclosure. This design supports a total of 80 amps for AC PV branch circuits and holds UL certification for safety and reliability.

The Enphase AC Combiner-3, equipped with the IQ Envoy, operates on a single-phase basis, delivering revenue-grade accuracy (ANSI C12.20 +/- 0.5%) alongside its calibrated solid-core CT. It has space for four Eaton BR 2-pole breakers, which must be purchased separately, and supports a maximum of 80 amps of power.

Included within the system are two split-core consumption CTs, also calibrated for revenue-grade accuracy (ANSI C12.20 +/- 0.5%) with the addition of a solid-core production CT. The package comes complete with the IQ Gateway, enhancing communication and control functions. An aesthetic solar shield is provided to align the unit's appearance with that of the Enphase IQ Battery while efficiently deflecting heat.

In terms of functionalities, the combiner supports production metering and comprehensive consumption monitoring. It features centered mounting brackets that allow for single-stud installation, as well as supporting conduit entry from the bottom, back, and sides. The design is fully compliant with the requirements for up to four 2-pole branch circuits for 240 VAC plug-in breakers, including necessary hold-down kits.

The unit's durable, NRTL-certified NEMA 3R enclosure adds a layer of protection, making it compatible with both IQ8 Series and IQ7 Series microinverters. It holds UL listing and adheres to standards set by IEEE 1547:2018, which includes UL 1741-SB, 3rd Edition, ensuring that it meets the highest safety and performance criteria.

In summary, the Enphase IQ Combiner 4 is a highly efficient solution for combining interconnection equipment in PV and storage installations, equipped with advanced capabilities for monitoring and communication while maintaining robust standards in safety and compatibility.
