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.
