IQ8X Microinverter
Current model: IQ8X-80-M-US
The Enphase microinverter we use for compatible high-voltage residential solar modules.
The Enphase microinverter we use for compatible high-voltage residential solar modules.
IQ8X is designed for compatible high-output, high-voltage modules, including many 80- or 88-half-cell and 96-cell designs. Sunstorm verifies the panel voltage, current, temperature behavior, and Enphase compatibility before specifying it. We use only IQ8X or IQ8HC for Enphase solar projects.
Final model, configuration, availability, and warranty terms are confirmed in the written proposal.

Key strengths
- Panel-level power conversion and monitoring
- Designed for compatible high-voltage modules
- Grid-forming capability within supported Enphase system designs
- Outdoor-rated enclosure and 25-year limited warranty
Best suited for
- REC Alpha Pure-RX and other electrically compatible high-voltage panels
- Roofs where module-level design and monitoring are priorities
- Enphase systems that call for the IQ8X electrical window
Questions this product must answer
- Is the selected panel listed as compatible with IQ8X?
- Do its voltage and current remain inside Enphase limits at site temperatures?
- What grid-interconnection profile applies?
- Which Enphase controller and communications equipment are required?
The complete system still matters
Capacity, output, efficiency, and warranty narrow the field. The final choice must also fit the roof, electrical design, permits, utility, and service plan.
Any proposed equipment substitution should be documented and reviewed before installation.
