Powerwall Physical Requirements
Powerwall can be mounted on a floor or wall. When floor-mounted, it must also be anchored
to an adjacent wall. In both types of installation, the wall must be capable of supporting the full
weight of Powerwall and its mounting hardware. The wall must extend to all edges of the
system, allowing no access to the back of the unit once it is mounted.
Powerwall includes a mounting bracket (Fig. 1) that supports the unit in both floor- and wall-
mount configurations, and includes shims to level the unit in floor-mount configurations. Do
not use other hardware to anchor Powerwall to the wall or floor.
Figure 1: Powerwall 2 Mounting Bracket Dimensions
Powerwall requires adequate clearance for installation, cabling, and airflow. Do not mount any
other objects within the clearance space (Fig. 2), except those explicitly required by the
installation (for example, conduit, a junction box, or an electrical disconnect, depending on
local installation codes). Do not install anything above Powerwall that limits access to the unit
or that might fall and damage the unit. Do not mount Powerwall horizontally or upside down.
NOTE: Powerwall has a pump and fan that enable Powerwall to maintain ideal battery
temperature. They produce a gentle hum during operation, comparable to a typical
refrigerator. The noise level depends on the ambient temperature and the power level of
operation. Consider these noise levels when choosing where to install Powerwall.
