Envoy-S Installation and Operation Troubleshooting The following sections describe possible problems and solutions. WARNING: Risk of electric shock. Risk of fire. Do not attempt to repair the Envoy-S; it contains no user-serviceable parts. Tampering with or opening the Envoy-S will void the warranty. If the Envoy-S fails, contact Enphase Customer Support for assistance (support@enphaseenergy.com). Warranty void if cover removed. Refer servicing to qualified personnel.
Envoy-S Installation and Operation 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 Envoy well located? The Envoy must be near the primary load center or the array's downstream subpanel.
Envoy-S Installation and Operation 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).
Envoy-S Installation and Operation Issue: Wi-Fi Problems If the Network Communications LED remains off: If the Envoy is installed in an enclosure, that enclosure must be non-metallic to allow wireless communication. Metal enclosures impede wireless communication. Stucco and plaster wall construction may contain metal mesh, which can affect wireless range.
Envoy-S Installation and Operation WARNING: Do not change the Envoy DHCP setting to use a static IP address unless you also reserve the same IP address on the broadband router. See the section on DHCP reservations in the router instructions. Failure to reserve the static IP address on the router may result in duplicate IP addresses and intermittent Internet connection problems with the Envoy-S. MAC Filtering Check to see if MAC filtering is in use at the site.
Envoy-S Installation and Operation An insulation resistance (IR) sensor in the microinverter measures the resistance between the positive and negative PV inputs to ground. If either resistance drops below a threshold, the microinverter stops power production and raises this condition. This may indicate defective module insulation, defective wiring or connectors, moisture ingress, etc. Although the cause may be temporary, this microinverter condition persists until the sensor is manually reset.
Envoy-S Installation and Operation If a microinverter registers a GFI Tripped condition, you can attempt to clear this condition. An Envoy is required to send the clear-gfi message to clear the condition. If the condition does not clear after you perform the following procedure, contact Enphase Energy customer support at support@enphaseenergy.com. There are two ways to send a clear message to the microinverter.
