Planning
The Enphase AC Battery is controlled by the Enphase Envoy-S Metered gateway. The AC Battery cannot
function without receiving commands from the Envoy-S. It is, therefore, critical that the Envoy-S and AC
Battery(ies) are located as close as possible to each other. The Envoy should be located within 20m
(electrically) from the AC Battery(ies).
However, this may not always be practical since the Envoy-S Metered also needs to be connected to the
production and consumption CTs that are installed around the main service and solar production circuits.
In this case, you may need to extend the CTs and reroute the solar circuit closer to the AC Battery(ies). One
solution is to install the AC Battery, the solar production circuits, and the Envoy-S on a common panel board.
Preparation
a.
Ensure that you have both of the following:
•
One or more Enphase AC Battery(ies) (Model IQ7-B1200-LN-I-INT01-RV0): the AC Battery
shipping box contains an Enphase AC Battery and an access panel cover.
NOTE
: Check the “Must Energize By” label on the shipping box to ensure that the
AC Battery is installed by the date shown.
•
One Enphase Wall-Mount Bracket for each battery. The wall-mount bracket shipping box
includes only the bracket. Brackets are available in two widths to accommodate 450mm and
600mm stud-spacing.
b.
Ensure that you have the following
required
items:
•
Enphase Envoy-S Metered (4.10 or later) communications gateway with production CT(s) and
consumption CT(s) installed and configured as described in the Enphase Envoy-S Metered Quick
Install Guide. When used with Enphase devices, the Envoy-S can control grid management
functions and monitor PV production and site consumption. When used with non-Enphase PV
systems, it can collect production and consumption data, but it does not control grid
management functions of non-Enphase PV system components.
NOTE
: The Enphase AC Battery requires an Internet connection (through the Envoy-S).
Maintaining this connection is important, for updating software and firmware, and for
measuring the health of the battery. Failure to maintain an Internet connection may have an

•
Mounting location that is structurally suited to bearing the weight of the AC Battery. The wall
must have appropriately spaced studs (450 mm or 600 mm) or can be of masonry or other
suitable structure.
NOTE:
If the wall is not structured in a way that allows wall mount brackets to be attached
directly to the studs, a substructure is required, such as
1
) metal strut, 6 mm (¼ inch) spring
nuts, and 6 mm (¼ inch) bolts or
2
) horizontally mounted wood studs or strong plywood.
•
Tools and accessories:
o
Conduit fitting tools, drill, 4mm pilot bit, screwdriver, socket, adjustable spanner, torque
wrench, level, 4mm Allen key, and wire stripper.
o
Four 6mm diameter lag bolts/screws, 25 to 50mm long depending on attachment wall,
for each wall-mount bracket. Check with a structural engineer and local standards for
requirements specific to your site.
o
Washers for use between fastener heads and wall-mount bracket.
