STEP 3: Wall-Mount Powerwall 3 Using Wall Bracket

Warning

Powerwall 3 must be mounted using the wall bracket at all times to secure the unit to the supporting structure.

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.

Figure 1. Bracket Measurements Relative to Powerwall and Floor

*Measurement is to floor.

Warning
Only install fasteners in the (4) slots on the horizontal bracket segments. Do not install fasteners on the vertical (center) segment, as these are not structural mounting holes.

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).
Move the dolly toward the wall, positioning Powerwall so that the mounting cleats are just above the flanges on the bracket.
Lower Powerwall until:
- The upper set of cleats is fully seated on the bracket flanges
- The lower set of cleats is engaging the bracket flanges
  Note
  Only the upper set of cleats will be fully seated; the lower cleats will still engage the bracket, but there will be a small gap between the lower cleats and the bottom edge of the bracket.
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.

Note
The top of each foot must be visible above the threaded boss; do not unscrew the foot so far that the top is no longer visible.
