7. Click "Administration", and when prompted for credentials, enter the username as ad-
min and the password as admin.
8. From the Admin menu, choose Device Conditions and Controls.
9. Click on the serial number of the unit exhibiting the GFI condition.
NOTE: Do not click or select the box under the column labeled "Select".
10. In the clear-gfi box, select "set".
11. Click "send command".
If the condition persists, and keeps happening, there may be a physical, installation reason
for it. Common reasons for GFI trips include:
•
Water ingress in the PV module itself, due to damage or defect of the surface or its seals
•
A pinched or crimped D/C wire from the PV module's junction box.
If GFI events persist after clearing the condition from the Envoy, and you have verified that
there is not a physical problem (water-ingress or a pinched lead), then the microinverter is
likely defective and must be replaced. Contact Enphase Customer Support.
Grid Gone
The inverter reports that power from the utility is no longer present or has gone out of
specification in terms of voltage and/or frequency. In most cases no action is required. Solar
production will resume when conditions normalize.
Enphase microinverters are utility interactive and require a connection to the utility.
•
Verify that the solar circuit breaker(s) are
on at the load center. If all breaker(s) are
on, the condition should clear itself.
•
If Grid Gone events repeatedly occur on
one microinverter or only on portions of
a branch, call Enphase Customer Support
for assistance.

What is a "Utility Interactive" inverter?
The NEC (National Electric Code) defines this
as, "An inverter intended for use in parallel
with an electric utility to supply common loads
that may deliver power to the utility." In other
words, it describes the type of inverter that
lets PV system owners export their excess
power back to the utility. For more information,
see our whitepaper on the subject at
