Enphase IQ Combiner 3P EU – 3-phase connection box

Enphase IQ Combiner 3P EU: complete 3-phase connection box

Plug-and-play enclosure for your Enphase solar power and storage system

The Enphase IQ Combiner 3P EU brings together all the necessary connection components for your Enphase system in a single, clearly organised, pre-wired enclosure. This streamlines both solar power and battery storage installations and significantly reduces installation time. The combiner contains a pre-installed IQ Gateway Metered, two IQ Relays (3-phase), a Communications Kit, two 4-pole circuit breakers, an IQ Gateway circuit breaker, a residual current device (RCD) and all supporting components – ready-fitted on a 3-DIN rail mounting.

Smart technology for comprehensive energy management

Seamless metering, monitoring and grid protection in a single system

The integrated IQ Gateway Metered forms the platform for comprehensive energy management and offers extensive remote maintenance and management of your IQ Microinverters and IQ Batteries. With three pre-wired Generation CTs and three supplied 100 A Consumption CTs with split cores, you can measure both PV generation and home consumption with an accuracy of ±1%. The two IQ Relays provide grid and system protection with PLC phase coupling (multi-phase) and DC injection monitoring. Communication takes place via integrated Wi-Fi (2.4 and 5 GHz), Ethernet or optional Mobile Connect, whilst the Communications Kit provides a Zigbee connection to IQ Batteries.

Robust Enphase IQ Combiner 3P EU for Dutch installations

Safe, durable and easy to install

The IQ Combiner 3P EU is designed for indoor installation and features an IP65-rated enclosure and IK08 mechanical impact resistance. The top-mounted cable entry simplifies all on-site cabling, and wall mounting can be carried out quickly. The integrated residual current device (30 mA, 63 A, type A, 4-pole) and the 4-pole B-curve circuit breakers (20 A supplied as standard) ensure safe operation within a 3-phase 400 V Y/230 V mains supply. The combiner supports 2 PV or storage circuits (each max. 16 A) and is compatible with IQ6, IQ7 and IQ8 microinverters, as well as with IQ Battery 3T and IQ Battery 10T. Please note: this product is not suitable for homes with TN-C earthing.
