Enphase IQ8HC-72-M-INT / IQ8 AC-72-M-INT Microinverter

Enphase IQ8HC & IQ8AC Microinverters: Maximum Optimisation per Panel

Enphase IQ8 series microinverters represent the next generation of smart photovoltaic solutions. Designed for the latest generation of high-power solar modules, the IQ8HC (384 VA) and IQ8AC (366 VA) models transform each panel into a standalone production unit, maximising your energy yield even in cases of partial shading or different orientations.

Why Choose Enphase IQ8 Microinverters?

Unlike traditional string inverters that convert the energy from multiple panels together, each Enphase microinverter optimises the output of a single photovoltaic module. This modular architecture offers unparalleled flexibility and increased reliability: if one panel is shaded or fails, the others continue to produce at their full potential.

Advanced Technology and Exceptional Performance

• Optimal efficiency: 96.8% European efficiency (IEC 61683 standard) for maximum solar energy conversion
• Proprietary ASIC chip: 55 nm technology with high-speed digital logic and ultra-fast response time to load variations
• Extended compatibility: Works with half-cell, bifacial modules and all recent photovoltaic technologies
• Wide operating range: 18-58 V (IQ8HC) / 28-45 V MPPT (IQ8AC) to adapt to different panel configurations

Simplified and secure installation

IQ8 microinverters feature pre-installed MC4 connectors that allow for quick and easy connection to photovoltaic modules. The compact (212 x 175 x 30.2 mm) and lightweight (1.1 kg) design makes handling and installation on roofs easy.

Two-wire cabling technology significantly reduces installation time and associated costs. In addition, theintegrated quick-stop function meets the most stringent safety standards to protect installers and users.

Intelligent Communication and Advanced Monitoring

Using PLC (Power Line Communication) technology, the microinverters communicate with each other and with the Enphase IQ Envoy gateway via the existing electrical wiring. This two-way communication enables:

• Real-time monitoring of each panel individually
• Remote diagnostics and early detection of anomalies
• Automatic optimisation of energy production
• Intelligent network management and Smart Grid compatibility

To benefit from all these features, the use of an IQ Envoy gateway is recommended (available separately).

Differences between IQ8HC and IQ8AC

Proven reliability and durability

Enphase microinverters have undergone more thanone million hours of cumulative testing to ensure their long-term reliability. The double-insulated (Class II) polymer enclosure with IP67 certification protects the electronics from dust, moisture and weather.

Enphase offers a 25-year manufacturer's warranty, demonstrating the manufacturer's confidence in the longevity of its products.

Scalability and System Integration

IQ8 microinverters integrate seamlessly into the Enphase Energy System ecosystem:

• IQ Gateway (Envoy): Communication and monitoring gateway
• IQ Battery: Storage batteries for maximum self-consumption
• IQ Cable: Optimised AC connection cables
• Q-Relay: Decoupling relay for grid compliance (single-phase or three-phase)

This compatibility allows you to start with a simple installation and gradually add features (storage, load management, etc.) as needed.

Compliance and Certifications

The IQ8HC and IQ8AC microinverters are CE certified and comply with current European directives, including:

• IEC 62548: Design requirements for micro-inverters
• IEC 61683: Efficiency measurement procedures
• Grid decoupling standards according to local regulations

Important: For three-phase installations, the use of a three-phase Q-Relay decoupling relay may be mandatory depending on your configuration and the requirements of your grid operator. See our Enphase three-phase Q-Relay.

Ideal Applications

• Residential installations with partial shading or complex roofs
• Commercial projects requiring accurate monitoring
• Extensions of existing installations thanks to modularity
• Multi-orientation roofs to optimise each slope
• Sites with high safety requirements (mandatory rapid shutdown)
