- Check if it self-resolves within 24 hours - Temporary power-line communication (PLC) glitches are common. Open the Enphase App, tap the
Array tab, and tap the grey panel to see when it last reported. If the outage is less than 24 hours
old, wait before troubleshooting further. - Identify how many panels are affected - A single grey panel suggests an isolated hardware or wiring issue. A group of adjacent panels may
indicate a branch/relay problem. All panels grey usually points to IQ Gateway communication or
provisioning failure. - Remove sources of electrical interference - Unplug any devices from the same outlet as the IQ Gateway: surge protectors, UPS units, power
strips, CFL bulbs, battery chargers, and electronic pest repellers. These devices can block the PLC
signal. Also check for large rotating motors (fans, refrigerators) on nearby circuits - Plug the Gateway directly into a wall outlet near the breaker panel - The IQ Gateway must be plugged directly into a wall outlet — never through a surge protector or extension cord. It should be on the same circuit branch as your solar disconnect or as close to the
main panel as possible to reduce PLC signal loss. - Run a new microinverter scan - In the Enphase App, go to the Devices tab and initiate a new device scan to re-detect microinverters. If devices were recently provisioned or the Gateway was replaced, they may need to be re-associated.

- A microinverter has never produced power since installation. A single microinverter continues to not report after 48+ hours and all self-help steps are done. Multiple Gateway replacements have not resolved reporting failures. You suspect a grounding or wiring fault. A microinverter shows signs of
physical damage or burn marks. - Enphase support portal - enphase.com/support
