Troubleshooting; Led Is Solid Red Or Not Lit; Battery Information Is Incorrect Or Absent In Installer Toolkit Or Enlighten; Check The Internet Connection - enphase AC Battery Installation Manual

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 the Envoy-S provides information about the status of the AC Battery, the PV
production, and the home energy consumption.

LED is Solid Red or Not Lit

If, after start up, the AC Battery LED is red
or not lit, check that the proper voltage
(240V line-to-neutral) is provided to the AC
Battery. To do this:
Remove the access cover on the

bottom of the battery.
Check that 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
240V/60Hz between the red, black
and white terminals.

Battery Information is Incorrect or Absent in Installer Toolkit or Enlighten

The Envoy-S manages the charging and discharging operations 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 the Installer Toolkit to check that the
Envoy-S has detected devices and that they are communicating.

Check the Internet Connection

If you do not see AC Battery information in Enlighten, check that 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 electrically 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.
