Device detection issues
If the Device Communications LED lights solid amber, it may be a
result of low light levels. If there isn’t enough sunlight to power up the
microinverters, they can’t communicate with the Envoy.
If there is sufcient daylight for the microinverters to power up, the issue
may be that the Envoy is having difculty communicating over the power
lines. To troubleshoot this issue:
• Check the Installer Toolkit mobile app to see which devices are not
communicating.
•
Check that the circuit breaker(s) in the Three Phase NPR for the PV
array are in the “ON” position.
•
Verify that the PV modules are connected to the microinverters.
•
Verify the PV module DC voltage is within the allowable range for the
microinverter.
c
Power production issues
If the Power Production LED lights solid amber, check the Installer Toolkit
mobile app to see which microinverters are not producing:
•
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, starting at the load
center.
•
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, rst check
to see that the AC connectors are fully seated. Next, check that each mod-
ule is providing the required startup voltage for the microinverter (22V). A
PV module that is failing or that is undersized may not generate enough
power for AC conversion.
d
Internet connection issues
If you are using Wi-Fi and the Network Communications LED remains off
or solid amber:
•
The WPS connection window may have timed out. Retry the connection
steps.
•
Make sure that the broadband router is connected and operational by
checking that other devices at the site can access the network.
•
Be aware that metal enclosures or obstructions impede wireless commu-
nication.
•
If you don’t see your router/access point in the list on the Envoy, or cannot
maintain a connection, you may need to add a wireless repeater to extend
the network range.
You can troubleshoot network issues with the Installer Toolkit mobile app by
tapping the Network button, then Diagnostic Tools.
If you are using the Enphase Mobile Connect modem and the Network Com-
munications LED remains off or lights solid amber, see Troubleshooting in the
Enphase Mobile Connect Installation Guide.
If you replace your router, congure the IQ Envoy Wi-Fi settings for the new
Wireless Network Name (SSID) and password, or use the WPS function
described in Installation Step 10.
e
Loss of AC to a single branch of microinverters
If a single branch of microinverters is not producing, it may indicate loss of
AC to the branch.
• Use a multi-meter set to AC to test the breaker lugs. The result should be
around 240 VAC.
• If not, switch the breaker off and on to reset.
f
Inoperable IQ Envoy (all LEDs off)
If the IQ Envoy is not receiving power, all LEDs will be off.
• Use a multimeter set to AC to test line 1 on the Envoy breaker to the AC
neutral busbar. The result should be around 120 VAC.
g
Inoperable IQ Envoy and no AC to branch
If a branch of microinverters is not producing and the IQ Envoy LEDs are off:
•
Test at the main lugs for L-L and L-N voltages. The results should
be around 240 VAC and 120 VAC respectively. If not, there may be a
problem with the wiring from the panel.
