Plan the Internet Connection
To use the
Enlighten
web-based monitoring and analysis software, additional requirements are:
•
Internet connection for the IQ Gateway through a traditional router or modem. Decide
whether to connect the IQ Gateway to the Internet using integrated Wi-Fi, or using a PLC
bridge with Ethernet cables.
•
One of the following Web browsers with cookies enabled: Chrome 44 or higher, Firefox 41 or
higher, Internet Explorer 11, Microsoft Edge for Windows, Safari 8 or higher.
Metering Considerations
The IQ Gateway-M 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 IQ Gateway outdoors, you must install it in an
NRTL certified NEMA type 3R (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:
•
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). Do not use shielded twisted pair
(STP) cable.
Create the Map and Install the PV Modules and Microinverters
Create the map and install the PV modules and microinverters. You will scan this map later using
Installer Toolkit and your mobile device.
(See “Method A: Provision Microinverters with Installer Toolkit”
on page 18.)
NOTE
: If needed, you can find an installation map at the back of any Enphase Microinverter
manual.
•
Create a paper installation map to record microinverter serial numbers and positions in the
array. Peel the removable serial number label from each microinverter and affix it to the
respective location on the installation map.
•
Peel the removable label from the bottom of the IQ Gateway and affix it to the installation map.
•
Always keep a copy of the installation map for your records.
