enphase AC Combiner Box Quick Install Manual

Q U I C K I N S T A L L G U I D E
Installing the Enphase AC Combiner Box
The Enphase AC Combiner Box™ combines up to three AC branch circuits of Enphase AC Batteries, M-Series Microinverters and/or S-Series Microinverters. To
install the Enphase AC Combiner Box, read and follow all warnings and instructions in this Guide and in the Enphase Envoy-S Installation and Operation Manual
at: enphase.com/support. Safety warnings are listed on the back of this guide. If you do not fully understand any of the concepts, terminology, or hazards out-
lined in these instructions, refer installation to a qualified electrician or installer. These instructions are not meant to be a complete explanation of a renewable
energy system. All installations must comply with national and local electrical codes. Professional installation is recommended.
The AC Combiner Box is an outdoor-rated, NRTL-certified NEMA type 3R, polycarbonate enclosure containing an Enphase Envoy-S™, circuit breakers, and wiring
for Envoy-S connections.

PREPARATION
A ) Download the Enphase Installer Toolkit mobile app and
open it to log in to your Enlighten account. With this app,
you can connect to the Envoy-S to track system installa-
tion progress. To download, go to
scan the QR code at right.
B) Check the box for the following items:
Enphase AC Combiner Box with Envoy-S
•
Ferrite bead to attach to your Ethernet Cable, if used
•
Enphase AC Combiner Box Quick Install Guide (this document)
•
C ) Make sure you have the following required items:
Plan to use screwdriver, pliers, and torque wrench.
•
Provide overcurrent protection in the load center in accordance with
•
NFPA 70, §705.12.
Provide suitable mounting hardware: use screws that are long
•
enough to secure the unit to the vertical mounting surface
Use copper conductors rated for wet locations and sized to meet
•
local code requirements and voltage drop/rise considerations.
(Breakers are rated for 14-6 AWG copper, and output lugs are rated
for 14-4 AWG copper).
Use only UL Listed rain-tight or wet location hubs for wire entry into
•
the enclosure.
D ) If you plan to do consumption metering:
Make sure you have two split-core consumption metering CTs (order
•
CT-200-SPLIT).
Check that there is enough space in the load center to install CTs.
•
Do not install the CTs in a panel where they exceed 75% of the wiring
space of any cross-sectional area within the load center.
E ) Decide how to connect the Envoy-S to the Internet: Use Wi-Fi, an En-
phase Mobile Connect modem, or Ethernet. Then, make sure you have
the following optional items, if needed:
Enphase Mobile Connect modem [order CELLMODEM-01 (3G) or
•
CELLMODEM-03 (4G)]
Ethernet over power line communication (PLC) bridge with Ethernet
•
cables (order EPLC-01)
Ethernet cable: 802.3, Cat5E or Cat6, unshielded twisted pair (UTP).
•
Do not use shielded twisted pair (STP) cable.
F ) Create a paper installation map to record device serial numbers and
positions in the array. You will scan this map later using Installer Tool-
kit and your mobile device.
Peel the removable serial number label from each device and affix it
•
to the respective location on the paper installation map.
Write the Envoy-S serial number on the paper installation map. Later,
•
you will need to enter this number in Installer Toolkit. You can type it
in manually or scan the label on the inside of the AC Combiner door.
Always keep a copy of the installation map for your records and to
•
upload to Enlighten later.
G ) Note that installation of the Combiner has two parts.
To ensure successful device detection, complete Part 2 after install-
ing any Enphase Microinverters and/or Enphase AC Battery(ies).
Note: If needed, you can find an installation map at the back of any
Enphase Microinverter Quick Install Guide.
