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 communi-
cate with the Envoy.
If there is sufcient daylight for the microinverters to power up, the issue may be that the
Envoy is having difculty 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 IQ Combiner 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 break-
er 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 module 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:
•
The WPS connection window may have timed out. Retry the connection steps.
•
Make sure that the broadband router is operational by checking that other devices
at the site can access the network.
•
Be aware that metal enclosures or obstructions impede wireless communication.
•
If you cannot see your router or access point in the list on the Envoy, or cannot
maintain a connection, it may be necessary to add a wireless repeater to extend the
network range.
If you are using Wi-Fi and the Network Communications LED
lights solid amber,
make sure that the broadband router is connected to the Internet by checking that other
devices at the site can access the Internet.
If you are using the Enphase Mobile Connect modem and the Network Communications
LED
remains off or lights solid amber, see Troubleshooting in the Enphase Mobile
Connect Installation Guide.
For any connection method, you can troubleshoot network issues with the Installer Toolkit
mobile app by tapping the Network button, then Diagnostic Tools.
If you replace the broadband router, congure the IQ Envoy Wi-Fi settings for the new
Wireless Network Name (SSID) and password, or use the WPS function described in
Installation Step 11.
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.
Using a multi-meter set to AC, refer to the gure below and test for the following
values:
•
Test point A to test point B. The result should be around 240 VAC.
If not, there may be a problem with the supply wiring.
•
Test point C to the screws on the load-side breaker screws (D). The result
should be around 120 VAC.
If not, switch the breaker off and on to reset. If this does not remedy the
problem, contact Enphase Customer Support (
enphase.com/en-us/support/
contact).
f
Inoperable IQ Envoy (all LEDs off)
If the IQ Envoy is not receiving power, all LEDs will be off.
Using a multi-meter set to AC, refer to the gure below and test for the following
values:
•
Test point A to test point C. The result should be around 120 VAC.
If not, check the supply wiring.
•
Test point C to test point D. The result should be around 120 VAC.
If not, contact Enphase Customer Support (
enphase.com/en-us/support/contact).
g
Inoperable IQ Envoy and no AC to branch
If a single branch of microinverters is not producing and the IQ Envoy LEDs are off,
do the following:
Using a multi-meter set to AC, refer to the gure below and test for the following
values:
•
Test point C to test point E. The result should be around 120 VAC.
•
Test point C to test point F. The result should be around 120 VAC.
•
Test point C to test point G. The result should be around 120 VAC.
•
Test point C to test point H. The result should be around 120 VAC.
If not, there may be a problem with the wiring from the panel.
