IQ7PLUS microinverter

Enphase IQ7PLUS-72-M-INT, usually written IQ7+, is a panel-level solar microinverter from the IQ7 generation. It has 290 W rated power and 295 VA maximum apparent power.

Input schedule

IQ7+ has a 16 to 60 V input range, a 22 V start-up voltage and a 27 to 45 V MPPT window. Maximum input current is 12 A, maximum short-circuit input current is 25 A and maximum input power is 440 W.

Maximum input power and rated AC power describe different sides of the microinverter. A module still has to fit the voltage and current schedule; its wattage alone does not establish a valid pairing.

AC branch and enclosure

The microinverter produces 230 V AC with 1.28 A maximum output current and 97.24% maximum efficiency. A 20 A circuit supports up to twelve units on a single-phase branch or 36 distributed across three phases. The corresponding IQ Cable section limits are twelve and twenty-one.

IQ7+ measures 212 × 175 × 30.2 mm without its bracket and weighs 1.1 kg with the mounting plate. It is rated IP67, operates from -40°C to 65°C and uses natural-convection cooling. Communications use power-line communication through the Enphase AC cabling.

Current position

Current new UK supply is unconfirmed. Great Britain warranty territory covers Scotland, England and Wales; Northern Ireland has separate terms.
