Troubleshooting
The following sections describe possible problems and solutions.
During installation, use the Enphase Installer Toolkit mobile app to verify AC Battery operation. The Installer
Toolkit, when used with Envoy-S provides information about the AC Battery status, PV production, and home
energy consumption.
LED is Rapidly Flashing Yellow or Not Lit
If, after starting up, the AC Battery LED rapidly
flashes yellow or is not lit, check that the proper
voltage (230V line-to-neutral) is provided to the AC
Battery. To do this:
•
Remove the access cover on the bottom
of the battery.
•
Check whether both the AC and DC
connectors are fully seated in the
receptacles.
•
Unplug the AC connector and test the
voltage and frequency at the terminals of
the junction box. You should detect
approximately 230V/50Hz between the
blue and white terminals and
approximately 230V between the blue and
green terminals.
Battery Information is Incorrect or Absent in Installer Toolkit or Enlighten
The Envoy-S manages the charging and discharging of the AC Battery. Ensure that the Envoy-S current
transformers (CTs) are correctly installed and that production and consumption metering are configured
correctly in Installer Toolkit. Once this is done, you can use Installer Toolkit to check that the Envoy-S has
detected the connected devices and that they are communicating.
Check the Internet Connection
If you do not see AC Battery information in Enlighten, check whether the Envoy-S and the Internet connection
are working.
Run a Device Scan
If needed, you can also provision devices either by scanning the AC Battery(ies) bar code(s) or by performing
a device scan. If the AC Battery(ies) cannot be detected by the device scan or if the AC Battery(ies) are not
communicating, you need to relocate the Envoy-S to be closer to the AC Battery(ies). This is because the
Envoy-S communicates with the AC Battery using power line communications. The Envoy-S and AC
Battery(ies) must be installed on the same phase.
Relocate the Envoy
When possible, locate the Envoy-S within 20 meters or 65 feet (electrically) from the AC batteries. This may
not always be practical since the Envoy-S must also be connected to the production and consumption CTs
that are installed around the main service and solar production circuits. If so, you can extend the CT leads as
