IQ8HC microinverter

Enphase IQ8HC-72-M-INT is a current UK panel-level microinverter with 380 W rated power, 384 W maximum AC output and 96.8% European weighted efficiency.

Input schedule

IQ8HC has an 18 to 60 V input range, a 22 V start-up voltage and a 29.5 to 45 V MPPT window. Maximum input current is 14 A, maximum short-circuit input current is 25 A and maximum input power is 560 W.

IQ8HC shares its 384 W maximum AC output with IQ8X, but the products have different input windows. IQ8X is designed for higher-voltage module types, while IQ8HC remains on the 60 V family schedule. They should not be substituted from AC output alone.

AC branch and enclosure

IQ8HC produces 230 V AC with 1.67 A maximum output current. Maximum efficiency is 97.4%, while European weighted efficiency is 96.8%. A 20 A circuit supports up to nine units on a single-phase branch or 27 distributed across three phases.

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

Warranty territory

The Great Britain warranty is 25 years in Scotland, England and Wales, conditional on an internet-connected IQ Gateway and the remaining terms. Northern Ireland needs its applicable document.
