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.
