Site Requirements
PHYSICAL REQUIREMENTS
Powerwall must be installed on an upright wall that can support 115 kg (254 lbs), the maximum
weight of Powerwall and its installation packaging. The wall must be flush and extend to all edges
of the system, allowing no access to the back of the unit once it is mounted. Do not mount
Powerwall horizontally or upside down. Do not mount Powerwall on a wall that is tilted backward
or forward more than 5 degrees.
Powerwall requires adequate clearance for installation, cabling, and airflow. Do not mount any
other objects within the clearance space illustrated below, except those explicitly required by the
installation (for example, conduit or DC disconnect depending on local installation codes). Do not
install anything between Powerwall and the ceiling.
Note: Powerwall has a pump and fan that produce a gentle hum during operation, comparable to
a typical refrigerator or dishwasher. This intermittent noise is normal and enables Powerwall to
maintain ideal battery temperature. The noise level depends on the ambient temperature and the
power level of operation. Choose the installation location of the Powerwall with due consideration
for the owner's sensitivity to noise level.
TEMPERATURE REQUIREMENTS
Powerwall is capable of charging and discharging within the full ambient temperature range listed
in the
Specifications section. At the high and low ends of the temperature range, Powerwall may
limit charge or discharge power based on battery cell temperature to improve battery lifespan.
Installation in full sun raises the temperature inside the enclosure above ambient temperature. This
temperature rise is not a safety risk, but can impact the performance of the batteries. Installation
in full sun is not recommended to optimize the use of Powerwall.
Do not install Powerwall in a room with sustained elevated temperatures, such as a boiler room.
The average ambient temperature over the system's life should be 30°C (86 °F) or less.
INSTALLATION REQUIREMENTS
Powerwall must be installed with a compatible inverter. Wiring and conduit (where necessary)
must be provided by the installer.
DC disconnect requirements between Powerwall and the inverter are subject to local codes.
Ensure that the installation meets local DC disconnect requirements. Check the inverter
installation manual to understand site connections and overcurrent protection.

Step-by-Step Installation Instructions
STEP 5 - PREPARE THE WIRING
Refer to local building and electrical codes when selecting appropriate wire gauge and length. Cut
the ends of the wires to have clean, even ends. Strip the ends of the wires enough to make solid
contact in the connector, while ensuring that no bare wire extends beyond the connector edge.
To ensure that installation is as simple as possible, select flexible wires with the smallest overall
approved diameter. The wiring compartment is relatively small and the use of small diameter wires
significantly speeds and simplifies the installation process.
A single 12 V power connection is required to power the logic. The Logic 12 V might be called
"Logic," "Always On," "Communication," or similar.
Caution: Do not splice wiring inside Powerwall.
Caution: Do not add extra wiring to the left of the conduit or gland entry. Additional wiring
may interfere with water ingress and high voltage shielding to the pump.
Note: Use shielded twisted pair communication wire and ground the shielding at one end. This
reduces the possibility of noise on the communication cable. Do not ground the shield at both
ends, which would create a ground loop.
Note: The 450 VDC cable is run in close proximity to the low voltage and communication cabling.
Therefore, ensure that all cables to Powerwall are:
• Wet or oil rated
• At least 600 V insulation class
If low voltage and communication wires do not already meet these requirements, 600V insulation
class heat shrink can be added around the bundle during installation.

raised printing on it that names each terminal.
1. Loosen the chassis ground screw terminal (1) with a flathead screwdriver.
2. Insert the ground/earth wire beneath the lug screw from the left side. Torque according to the
wire size:
• 2.5-5 mm2 (14-12 AWG): 4.0 Nm (35 lbf-in)
• 6-8 mm2 (10-8 AWG): 4.5 Nm (40 lbf-in)
3. Pull both high voltage locking tabs on the spring terminal (2) away from the board to open
them.
Note: New tabs can be dicult to close. Close and open each tab once without wires before
installation.
4. Route the positive (+) and negative (-) DC power wires behind the red and black internal DC
wires, and fully insert them into the spring terminal tabs. The left slot is Positive and the right
slot is Negative.
5. Close the locking tabs by pushing them up, so that the tab is flush with the connector. Close
tabs one at a time. Lightly tug on each of the HV wires to ensure it is secure. If any wire must
be removed, pull the locking tab open, then pull out the wire.

STEP 13 - FEED WIRES THROUGH THE CONDUIT PLATE OR CABLE GLAND
Depending on regional requirements, Powerwall can be installed either through conduit or
through a cable gland. Follow local codes to determine which is appropriate.
The conduit plate hole has a 28.2 mm (1.11 in) diameter. It supports ¾” trade fittings, and PG-21 and
M25 glands. The conduit plate has passed water ingress testing with individual cables squeezed
together in a single gland. All fittings other than the conduit plate itself are provided by the
installer.
The access point on Powerwall is centered on the bottom of the device.
1. Use a T30 Torx driver to remove the conduit plate.
2. For conduit configurations, feed the wires through the conduit and conduit opening. Make
sure that wires are not frayed.
3. For cable gland

STEP 14 - CONNECT MULTIPLE POWERWALLS TOGETHER
If the site is installing multiple Powerwalls, follow these instructions for wiring the units. If not, skip
to the next step.
Caution: Do not splice wiring inside Powerwall.
Note: Ensure that the multi-Powerwall installation meets local requirements for DC disconnects
and correctly rated overcurrent protection.
Note: Always check with the inverter partner for inverter abilities and instructions before
connecting multiple Powerwalls.
1. Remove the splash cover as described above.
2. Verify that the communication and address switch settings for each Powerwall in the chain are
accurate as described in the above steps.
3. Connect the wiring coming from the inverter (communications +/-, enable line, and 12V Logic
+/- wires) to the J7 connector as the primary connector.
4. Connect the output communications, enable, and 12V logic wiring going toward the next
Powerwall to the J6 connector (see previous circuit board image). Powerwall allows daisy
chaining of low voltage and communication cables.
5. Run DC power wiring independently to each Powerwall. Fuse each Powerwall individually.
6. Reinstall the splash cover.
STEP 15 - CONNECT POWERWALL TO THE INVERTER
Run the wires between Powerwall and the inverter as described in the inverter manual. Follow
local electrical installation codes for wire installation.
Note: Ensure that the installation meets local requirements for DC disconnects and correctly rated
overcurrent protection.

STEP 17 - ATTACH THE BOTTOM COVER
1. Line up the bottom cover with the bottom of Powerwall, between the side covers.
2. Tuck the back edge of the bottom cover (closest to the wall) under the metal edge of the
Powerwall body.
3. Route the wires to run from the conduit plate or gland back (toward the wall) below the
ground/earth lug, then forward again to match the internal wiring harness path under the
splash cover into the circuit board. Verify that the wires are not pinched or kinked by the
internal edge of the bottom cover.
4. Close the bottom cover carefully over the wiring. Verify that the edge of the bottom cover is
tucked completely under the lip of the front cover.
5. Use a 10 mm hex socket to attach the bottom cover with an M6 screw on each side. Torque to
3 Nm (27 in-lbs).
6. Once installation is complete, gently peel the protective sticker from Powerwall's front cover.
STEP 18 - REPACK THE SHIPPING BOX
All Powerwall packing material is recyclable. To facilitate this process, place the packing materials
into the shipping box in reverse order and return the shipping box to the Tesla Energy Authorized
Reseller, or recycle onsite as appropriate.

Operation and Care
NORMAL OPERATION
During normal operation, Powerwall is completely controlled by the inverter. If Powerwall and the
inverter are installed correctly, the inverter can turn on Powerwall, begin communications, then
begin to process power commands. See the inverter manual for further configuration instructions.
Warning: Do not operate Powerwall unless all covers are in place.
Warning: Do not disconnect anything from or add anything to Powerwall.
Caution: Do not try to communicate with Powerwall using third party tools or diagnostics
between Powerwall and the inverter.
Caution: Do not lean on, stack anything on top of, or hang anything from Powerwall or the
conduit.
POWERWALL CARE
Keep the top edge of Powerwall clear of leaves and other debris if installed outside, to maintain
optimal
airflow.
To clean Powerwall, use a soft, lint-free cloth. The cloth can be dampened with only water if
needed.
Caution: Do not use cleaning solvents to clean Powerwall.
TROUBLESHOOTING
