Issue: No Microinverters Are Reporting; Power Production Issues; Issue: Power Production Led Is Solid Amber - enphase AC Combiner Box Installation Manual

Check Enlighten or use the Installer Toolkit to connect to the Envoy to see if any microinverters
•
are not reporting in to the Envoy or having any error conditions.
If this problem occurs when light levels are low, try again during daylight hours.

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 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.

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 upgrade is in progress, flashes amber when microinverters are not yet detected, or becomes
solid amber when any microinverter that is expected to produce is not. Check in Installer Toolkit to see which
microinverters are affected.
If none of the microinverters are producing power, there may be a grid or wiring issue. First,
•
verify that there is proper input voltage and frequency from the utility. Next, check the breaker
and wiring.
If all of the non-productive microinverters are on the same branch, check the breaker and wiring
•
starting at the junction box for the affected branch.
• If only one or scattered microinverters are not producing power, first check to see that the AC
connectors are fully seated in the Engage Cable connectors. Next, check that each module is
meeting the required startup voltage for the microinverter (usually 22 V). A PV module that is
failing or that is undersized may not generate enough power for AC conversion.
Refer also to "Microinverter Detection Issues" on page 25 because the microinverters will not
•
report production if they are not communicating with the Envoy-S.
