Plan the Internet Connection
To use the
Enlighten
web-based monitoring and analysis software, additional requirements are:
Internet connection for the Envoy-S through a traditional router or modem or Enphase Mobile
Connect (Enphase model CELLMODEM-02). Decide whether to connect the Envoy-S to the
Internet using integrated Wi-Fi, an Enphase Mobile Connect modem, or using a PLC bridge
with Ethernet cables.

Metering Considerations
The Envoy-S Metered includes a production CT and a consumption CT. When installing CTs:
Do not install the CTs in a panel where they exceed 75% of the wiring space of any cross-
sectional area within the panel, or refer to local standards for guidance.
To install the
production CT
, which measures power production through a connection to the solar supply
main switch:
Ensure there is sufficient space to install the production CT around Line (active) of the solar
supply main switch.
To install
consumption CT,
which measures energy consumption through a connection to the AC mains:
For net consumption metering, ensure there is sufficient space to install the CT around Line
(active) from the main feeds.
For total (gross) consumption metering, ensure there is sufficient space to install the CT
around the line that feed the consumption circuit.
Required Items
If you hard-wire the Envoy-S outdoors, you must install it in an
IP54-rated (or better) enclosure with
conduit attachment.
Note that Metallic enclosures may impair Wi-Fi signal strength.
Use an appropriately rated enclosure if hard-wiring indoors. Do not drill holes for conduit at the top of the
enclosure or anywhere that allows moisture ingress.
Optional Items
Make sure you have the following optional items, if needed:
Enphase Mobile Connect modem (order Enphase CELLMODEM-02)
Ethernet over power line communication (PLC) bridge with Ethernet cables [order EPLC-02
(EU), EPLC-03 (UK) or EPLC-04 (AU) separately]
Ethernet cable (use 802.3, unshielded Cat5E or Cat6)
