Issue: No Devices Are Reporting; Issue: Installer App Indicates That Scanning Is Inhibited - enphase Envoy-S Installation And Operation Manual

•
Relocate your IQ Gateway as close to the switchboard as possible. This ensures that
the IQ Gateway receives the strongest possible signal from each device.
•
If this problem occurs when light levels are low, try again during daylight hours.

Issue: No Devices 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 IQ
Gateway to communicate with the devices, the PV circuit breakers must be in the "ON"
position at the switchboard.
•
Verify that the PV modules are connected to the microinverters.
Is the IQ Gateway well located? The IQ Gateway must be near the primary switchboard or the array's
downstream sub-board. If installing the IQ Gateway Standard:
•
As an alternative if signal strength is poor, power the IQ Gateway 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 IQ
Gateway must be located indoors (a garage, attic, basement, or other cool, dry location)
or in an NEMA 3R or better enclosure. Remember that the IQ Gateway must also
have an Internet connection.
Is the system energised? 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 IQ
Gateway to communicate with the microinverters, the PV circuit breakers must be in the
"ON" position at the Switchboard.
•
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 Gateway wired into a circuit on the primary switchboard while the PV circuit
breakers are on a downstream sub-board? The primary switchboard is full and doesn't have
additional capacity to add circuit breakers.
•
Add a sub-board with a small subset of circuit breakers.
•
Hard wire the IQ Gateway into that sub-board, so that it can be close to the PV circuit breaker.

Issue: Installer App Indicates that Scanning is Inhibited

It is best to leave the IQ Gateway in this condition for normal operation. However, if you need to
re-enable scanning (for example, if you replace a device) contact Enphase Customer Support
(enphase.com/global/support-request).
