The Enphase microinverter we use for compatible higher-current residential solar modules.
IQ8HC is optimized for compatible higher-current solar modules while delivering 380 VA of continuous output. Sunstorm verifies the panel voltage, current, temperature behavior, and Enphase compatibility before specifying it. We use only IQ8X or IQ8HC for Enphase solar projects.
Your proposal names the exact model and setup we’ll install.

Before we recommend it
What we’ll figure out with you
- Is the selected panel listed as compatible with IQ8HC?
- Does the panel stay within Enphase’s electrical limits in Florida heat?
- What does your utility require to connect the system?
- Which Enphase controller and communications equipment are required?
It has to fit your whole system
Specs narrow the field. We also make sure it fits your roof, your electrical panel, your permit and your utility’s rules.
If a model ever has to change, we tell you before installation.
