Warning
Powerwall 3 must be mounted using the wall bracket at all times to secure the unit to the supporting structure.
  1. Using a drill and level, mount the Powerwall bracket to a wall capable of supporting the full weight of Powerwall 3. See Anchoring Details for Ground- or Wall-mounting Powerwall 3 with Wall Bracket on Existing Approved Foundation for additional details on the type and number of fasteners to use.

    Note
    The following diagram provides measurements for positioning rear conduit entry holes relative to the Powerwall 3 bracket (the measurements are the same for both knockouts).
  2. Move the dolly toward the wall, positioning Powerwall so that the mounting cleats are just above the flanges on the bracket.
  3. Lower Powerwall until both the upper and lower sets of cleats engage the flanges on the bracket.

    CAUTION
    Confirm Powerwall 3 is fully seated on all four cleats before proceeding.
  4. If ground-mounting Powerwall, use a 17 mm wrench to adjust the leveling feet until Powerwall is level. The unit should be level within ± 2 degrees side-to-side and within ± 5 degrees front-to-back.
