The Story

The Enphase IQ7+ Microinverter (Three-Phase Installation) (model IQ7PLUS-72-2-INT) is Enphase's seventh-generation microinverter for 60-cell and 72-cell (including 120 and 144 half-cell) PV modules, deployed in three-phase IQ Cable systems across 230/400 V commercial and larger residential sites. It delivers 295 VA maximum apparent power (290 W rated) per unit at 230 V L-N. In three-phase configuration, units are distributed evenly across L1, L2, and L3 via the three-phase IQ Cable — allowing up to 36 microinverters per three-phase 20A circuit. Certified to G98, G98 NI, G99, G99 NI, and G100, carrying CE and UKCA marks, and backed by an industry-leading 25-year limited warranty (with connected IQ Gateway).

⚠ Installer Requirement: The IQ7PLUS-72-2-INT uses an Enphase IQ Cable (AC) and Q-DCC-2 MC4 adapter cable (DC) — it does not have integrated DC connectors and ships with the Q-DCC-2 adapter. Three-phase installations require the three-phase IQ Cable (Q-25-xx-3P variants). G99 notification is likely required for commercial three-phase systems — confirm with the DNO. UKCA and CE marks both apply for UK market.
⚠ Module Compatibility: The IQ7PLUS accepts modules with a DC MPP voltage range of 27–45 V and a maximum Voc of 60 V. It is compatible with 60-cell/120 half-cell and 72-cell/144 half-cell modules. For 96-cell or 80+ half-cell high-power modules, the IQ7X or IQ8X is a better match. Verify compatibility at enphase.com/en-gb/installers/microinverters/calculator.
ℹ IQ7/IQ8 Mixed Systems: IQ8 Series microinverters cannot be added to a site where IQ7+ units are installed on the same IQ Gateway once the site has IQ8 units active. If you are specifying a new system and anticipate adding IQ8 units later, consider specifying IQ8 Series from the outset. IQ7 units on an existing solar-only site can have IQ8 units added for Solar Only or grid-tied Solar + Battery configurations.
36 Units Per Three-Phase 20A Circuit

The IQ7PLUS supports up to 36 units per three-phase 20A circuit (12 per phase) — more units per circuit than the higher-output IQ8 models because its lower per-unit current (1.28 A) leaves more headroom within the 16 A per phase limit. For fixed-budget commercial projects where maximising array panel count per circuit matters, this is a meaningful advantage.

Q-DCC-2 Adapter — MC4 Module Compatibility

Unlike the IQ8 Series with integrated MC4 connectors, the IQ7PLUS uses a Q-DCC-2 adapter cable with MC4 connectors for DC connection. This adapter is included with the microinverter. The Q-DCC-2 enables connection to all standard 60/72-cell modules with MC4 DC output connectors without any field wiring.

Three-Phase Auto-Balancing via IQ Cable

Three-phase IQ Cable automatically distributes microinverter output across L1, L2, and L3 in sequence. This eliminates manual phase assignment during installation and ensures the generation is balanced across phases from the first panel — important for DNO G99 phase balance requirements and for minimising neutral current on the installation.

Seven Generations of Reliability

The IQ7 Series has been through more than one million cumulative hours of power-on testing and has a proven real-world track record across many millions of installed units globally. The seventh-generation platform incorporates lessons from over a decade of microinverter deployments — delivering higher reliability than its predecessors and the lowest failure rates in Enphase's product history.

UKCA and CE Dual Marking

The IQ7PLUS carries both UKCA and CE marks — important for UK market installations where UKCA is becoming the required conformity marking post-Brexit. UK installers can specify the IQ7PLUS with confidence that it meets both UK conformity requirements and European standards, useful for any cross-border commercial projects.

Remote Firmware Updates

All IQ7 Series microinverters receive firmware and grid compliance updates remotely via the IQ Gateway — no site visit required. As UK grid standards evolve (G98, G99, G100 profile updates), the installed base can be updated centrally, keeping commercial sites in compliance without costly engineer visits.

How does the IQ7PLUS differ from the IQ8AC in three-phase use?
The IQ7PLUS outputs 295 VA vs 366 W for the IQ8AC, and operates from a slightly lower DC voltage range (MPP 27–45 V vs 28–45 V). The IQ7PLUS allows 36 units per three-phase 20A circuit vs 30 for the IQ8AC — useful for maximising panel count on a large commercial roof. The IQ8AC delivers more power per panel and higher EU efficiency (96.6% vs 96.5%). For new installations, the IQ8 Series is generally preferred; IQ7PLUS is the option for sites requiring IQ7-Series compatibility or specific module matching.
Can IQ7PLUS and IQ8 microinverters coexist on the same site?
Yes — on the same IQ Gateway, IQ8 units can be added to existing IQ7 systems for Solar Only or grid-tied Solar + Battery configurations. However, IQ7 units cannot be added to a site where IQ8 units are already installed on the same gateway. Mixed sites also lose the IQ8-specific Sunlight Jump Start feature.
What DC connector does the IQ7PLUS use?
The IQ7PLUS-72-2-INT ships with a Q-DCC-2 adapter cable that terminates in Stäubli MC4 connectors. This is the standard approach for IQ7 Series — unlike IQ8, which has MC4 connectors integrated directly into the microinverter body.
How many IQ7PLUS units per three-phase 20A circuit?
A maximum of 36 units per three-phase 20A circuit (12 per phase at 1.28 A per unit). Per IQ Cable section: maximum 21 units (three-phase). Centre-feed the IQ Cable sections for best voltage management.
Does the IQ7PLUS carry UKCA marking for UK post-Brexit compliance?
Yes. The IQ7PLUS-72-2-INT carries both UKCA and CE marks, making it suitable for UK market installations under both the current transitional and the forthcoming mandatory UKCA regime.
