Site Requirements

Stacked Powerwall+ and Powerwall systems must be floor-mounted, with all units installed on a structurally sound flat surface that supports both feet of each unit. They must also be anchored to an adjacent wall which must be capable of supporting the lateral load of the stack.

A maximum number of 1 floor-mounted Powerwall+ and 1 floor-mounted Powerwall may be joined together with a Powerwall Stack Kit. For systems with more than 2 units, separate groups of 2 units should be assembled, with each group of 2 attached to a wall.

For complete Powerwall+ Mechanical Specifications and Site Requirements, see Powerwall+ with Backup Gateway 2 Installation Requirements.

Note
Powerwall+ meets the unit level performance criteria of UL 9540A, allowing Powerwall+ to be installed stacked front to back with Powerwall 2 as long as the clearance requirements defined in this manual are followed to allow for air flow around the units.
