Enphase Microinverter 1-ph 384 VA Micro-Inverter MC4
General information: The Enphase Microinverter IQ8HC-72-M-INT is a single-phase microinverter from the IQ8 series with a maximum AC apparent power of 384 VA and a rated power of 380 W. It was developed for the decentralised conversion of solar power and is connected directly to a compatible photovoltaic module. The microinverter features integrated Stäubli MC4 connectors, an MPP tracker and a 230 V grid connection. Its compact design makes it suitable for mounting directly beneath the solar module.
Function: The Enphase IQ8HC microinverter converts the direct current generated by the connected solar module into grid-compliant alternating current. The integrated MPP tracker optimises the operating point of each connected module individually. This allows different module orientations, shading or soiling of individual solar modules to be taken into account without fixing the operating point of the other modules. The inverter supports a maximum DC input current of 14 A and operates with an MPP voltage range of 29.5 to 45 V. The maximum DC input voltage is 60 V.
Application: The Enphase Microinverter 1-ph 384 VA Micro-Inverter MC4 is suitable for grid-connected photovoltaic systems with compatible solar modules. It supports modules with 54, 60, 66 or 72 full cells as well as the corresponding half-cell configurations. Actual compatibility must be verified on the basis of the electrical module parameters and the manufacturer's specifications. The unit is mounted on the PV mounting structure beneath the solar module. Enphase IQ Cabling is used for the AC connection. The IQ Gateway enables system communication and monitoring of energy production via the Enphase App. Installation and commissioning require the respective system components, including the appropriate IQ Relay in accordance with local grid connection requirements.
Material: The housing of the Enphase IQ8HC-72-M-INT is made of a double-insulated, corrosion-resistant polymer of protection class II. The IP67 degree of protection allows outdoor use. In accordance with the manufacturer's instructions, the microinverter is mounted beneath the PV module and protected from direct exposure to rain, UV radiation and other harmful weather influences. Heat is dissipated by natural convection without fans. The unit measures 212 x 175 x 30.2 mm without mounting bracket and weighs 1.1 kg including mounting plate.
Technology: The technical features of the Enphase IQ8HC-72-M-INT include a maximum DC input power of 560 W, a maximum input voltage of 60 V and a start-up input voltage of 22 V. The maximum input short-circuit current is 25 A, while a maximum permissible short-circuit current of 20 A, taking into account the safety factor of 1.25, is specified for module selection. On the AC side, the microinverter offers a rated power of 380 W, a maximum apparent power of 384 VA and a maximum output current of 1.67 A at a rated grid voltage of 230 V and 50 Hz. The maximum efficiency is 97.33 % and the European efficiency is 96.7 %. Communication with the IQ Gateway takes place via power line communication (PLC). The permissible ambient temperature range is -40 to +65 °C.
Conclusion: The Enphase Microinverter 1-ph 384 VA Micro-Inverter MC4 combines a maximum AC apparent power of 384 VA, individual module optimisation through MPPT and integrated MC4 connectors in a compact, IP67-protected housing. Passive cooling, decentralised energy conversion and integration into the Enphase IQ System enable its use in flexibly configurable, grid-connected photovoltaic systems.

FAQ
Which solar modules are compatible with the Enphase Microinverter 1-ph 384 VA Micro-Inverter MC4?
- The microinverter supports PV modules with 54, 60, 66 or 72 full cells as well as the corresponding half-cell modules. The maximum input voltage is 60 V and the maximum input current is 14 A. Electrical compatibility must be checked before connection.
Can the Enphase Microinverter 1-ph 384 VA Micro-Inverter MC4 be installed outdoors?
- Yes, the unit has an IP67 degree of protection. In accordance with the manufacturer's instructions, it is mounted beneath the PV module, protected from direct sunlight, rain and other harmful weather influences. The specified mounting clearances must be observed.
How does the Enphase Microinverter 1-ph 384 VA Micro-Inverter MC4 perform under shading?
- Each microinverter has its own MPP tracker, so the output of the connected solar module is optimised individually. Shading of a single module therefore does not directly affect the operating point of the other modules.
