Issue: No Microinverters are Reporting
Check for the following conditions.
Has a device scan been run while the array was active? A device scan may have been run while the array
was not connected to the grid or when the array was not powered by sunlight.
• Run another scan during daylight hours.
• Check that the circuit breaker(s) for the PV array are in the ON position. For the Envoy to
communicate with the microinverters, the PV circuit breakers must be in the ON position in the
electrical load center.
• Verify that the PV modules are connected to the microinverters.
Is the Envoy well located? The Envoy must be near the primary load center or the array's downstream
subpanel.
• If signal strength is poor, power the Envoy from the solar production circuit (where local electrical
code allows for monitoring equipment on the same circuit). This provides the best possible power
line communications. The Envoy must be located indoors (a garage, attic, basement, or other cool,
dry location) or in an NRTL-certified, NEMA type 3R enclosure. Remember that the Envoy must also
have an Internet connection.
Is the system energized? PV modules power microinverters, PV modules provide power only during
daylight hours, and microinverters communicate only when powered.
• Run another scan during daylight hours.
• Check that the circuit breaker(s) for the PV array are in the ON position. For the Envoy to
communicate with the microinverters, the PV circuit breakers must be in the ON position in the
electrical load center.
• Verify that the PV modules are connected to the microinverters.
Is there a phase imbalance?
• Ask the electrician to measure the conductors and neutral line to verify that the phases are balanced.
If the phases are not balanced, electricians must recheck the wiring.
Is the IQ Envoy wired to a circuit on the primary load center while the PV circuit breakers are on a
downstream subpanel? The primary load center is full and doesn’t have additional capacity to add circuit
breakers.
• Add a subpanel with a small subset of circuit breakers
• Hard wire the IQ Envoy into that subpanel, so that it can be close to the PV circuit breaker.
Issue: Installer Toolkit Indicates that Scanning is Inhibited
It is best to leave the Envoy in this condition for normal operation. However, if you need to re-enable
scanning (for example, if you replace a microinverter) contact Enphase Customer Support at

Power Production Issues
Issue: Power Production LED is solid amber
The Power Production LED is solid green when all microinverters are producing, flashes green when a
microinverter update is in progress, flashes amber when microinverters are not yet detected, or becomes
