PREPARATION
A ) Inspect the packaging and the IQ System Controller 2 for damage. Do
not install or use the IQ System Controller 2 if it has been damaged in
any way.
B ) Ensure that you have the following:
•
One Enphase IQ System Controller 2. The IQ System Controller 2 shipping
box contains an Enphase IQ System Controller 2, mounting bracket,
mounting hardware, and literature kit (bag with labels and accessories:
150-00148). Among the accessories are four-pin receptacles/dry contacts
that will be used for controlling external power relays.
*
WARNING:
The IQ System Controller 2 weighs 39.4 kg (87 lbs) and
will require two persons to lift the unit.
C ) Make sure you have the following
required
items:
•
Enphase IQ Battery, which is required for off-grid applications.
•
The Enphase IQ System Controller 2 requires a wireless connection
to an IQ Gateway, which requires an Internet connection. Failure to
maintain an Internet connection may have an impact on the warranty.
for full terms and services.
•
Wireless USB Adapter (COMMS-KIT-01) to be installed at IQ Gateway
for communications with IQ Battery and IQ System Controller 2.
Includes USB cable for connection to IQ Gateway and allows wireless
communication with IQ Battery and IQ System Controller 2.
•
Two current transformers (CT-200-SPLIT) for consumption monitoring
•
One current transformer (CT-200-SOLID) for production metering
•
IQ System Controller 2 lifting handles (EP200G-HNDL-R1).
•
Eaton BR Series breakers, rated maximum 80A for IQ Battery and
Enphase IQ Combiner.
•
If breakers are required at the input or output to IQ System Controller
2, use Eaton, Type CSR breakers rated 100 A, 125 A, 150 A, 175 A or
200 A.
•
Tools: conduit (with fittings and fitting tools), drill, 5/32 inch pilot bit
(or metric equivalent), screwdriver, socket, wrench, adjustable wrench,
torque wrench, level, 5/32 inch Allen key (or metric equivalent),
conductor stripper, electrician’s hole saw (2 inch) kit or punch set, and
stud finder, if installing on studs.
•
Conduit fittings (hubs) are required for all installations, and NEMA
Type 3 conduit fittings (hubs) are needed when installing out of doors
(one for each used conduit opening).
•
Conduit ground hub rings.
NOTE
: Conduit entry is allowed only through the bottom or bottom sides
of the unit.
•
Three #10, 1/4”, or 5/16” lag bolts or screws, 7.6cm (three inches) long
(depending on attachment wall), for each wall-mount bracket. Check with
a structural engineer and local standards for local requirements.
•
Washers for use between fastener heads and wall-mount bracket.
•
Conductors rated at 75°C.
For sizes, refer to the table on the unit and
to local codes.
•
Over current protection: maximum in accordance with local standards.
•
The door sheet metal is not required to be grounded, since it is pro-
tected from live parts by other grounded metal and insulating plastic
materials, thus is considered unlikely to become energized.
INSTALLATION
Use the
Enphase Installer App™
mobile app for iOS and Android devices. It
allows installers to configure the system while on site, eliminating the need
for a laptop and improving installation efficiency.
NOTE:
Only one IQ System Controller 2 can be commissioned in one
system. Multiple IQ System Controller 2s can exist on the same site but
they need to be in separate systems, i.e. separate Enphase App/Enphase
Installer App activations.
Plan a location for the IQ System Controller 2
The IQ System Controller 2 housing is NEMA type 3R and you can install it indoors
or outdoors.
*
WARNING:
Protection against lightning and resulting voltage surge
must be in accordance with local standards.
A )
Follow all local codes and standards when planning for and installing
the Enphase IQ System Controller 2.
B ) Choose a well-ventilated location where the ambient temperature
is within -40° C to 50° C (-40° F to 122° F), preferably out of direct
sunlight.
C ) Ensure that the mounting location can sustain the weight of the IQ
System Controller 2 and mounting bracket
39.4 kg (87 lbs)
. The wall
must include studs that can bear
39.4 kg (87 lbs)
or can be of masonry
or other suitable structure that can bear the weight.
D ) Check the mounting location clearances:
•
Indoors: at least 15cm (six inches) off the
ground, 15cm (six inches) from the ceiling,
and 15cm (six inches) on each
side.
•
Outdoors: at least 91cm (three
feet) off the ground and 15cm
(six inches) on each side.
E ) Ensure that there are no pipes or
electrical conductors where you
plan to drill.
F ) Plan to maintain at least 90cm
(three feet) of clearance in front
of the IQ System Controller 2.
G ) Consider the dimensions of the
IQ System Controller 2, easy
access, unit height, conduit
entry, and length of cable when
selecting the location.
H ) Select a location where you can
interconnect to the site’s load
center using the Enphase IQ
System Controller 2.

Scenario 4:
Partial home backup with Solar
Only backup:
This is the preferred
configuration for partial home
backup with subpanel using only IQ8
PV. Generator can be integrated with
IQ System Controller based on the
homeowner’s needs.
