Enphase IQ7 Plus 60 and 72 cell MC4 integrated Microinverter 230 & 400VAC.
Enphase IQ7 Plus 60 and 72 cell MC4 integrated Microinverter 230 & 400VAC.
The Enphase IQ7PLUS-72-M-INT is a 295 VA microinverter, one per module, with integrated Stäubli MC4 connectors and an MPP window of 27 to 45 V.
A microinverter converts one module's DC to grid AC at the module itself, rather than running a whole string down to a single inverter. Nothing on the roof ever carries high-voltage DC, one shaded or underperforming module cannot drag the rest of the string down with it, and every module is monitored individually.
The IQ7 series is Enphase's previous generation and remains the cost-effective choice for a straightforward array. It uses the same IQ Cabling and the same IQ Gateway as the IQ8, and IQ7 and IQ8 units can be mixed on one system.
Output (AC)

Input (DC)
| Typical module compatibility | 60-cell / 120 half-cell, 66-cell / 132 half-cell, 72-cell / 144 half-cell |
| Minimum / maximum input voltage | 16 / 60 V |
| Start-up input voltage | 22 V |
| Rated input voltage | 36 V |
| Minimum / maximum MPP voltage | 27 / 45 V |
| Minimum / maximum operating voltage | 16 / 60 V |

There is no enforced DC to AC ratio: a module can be paired with the microinverter as long as the maximum input voltage is not exceeded and the maximum input current is respected at the lowest and highest temperatures the site will see. Pairing a module above the input power limit simply clips.

What else the system needs
Microinverters do not work in isolation. Every Enphase array needs an IQ Gateway to poll the units, report to Enphase Enlighten and unlock the full warranty term, and it needs IQ Cabling — the microinverters connect to a purpose-made AC trunk cable, not to ordinary T&E.
