APPENDIX H: MULTI-POWERWALL INSTALLATIONS
• Water-resistant heavy-duty grease (Dow Corning Molykote BR-2 Plus High Performance Grease or
equivalent, for preventing corrosion on side clips)
• Installation tools (level, tape measure, pencil, flashlight)
Site Requirements
Stacked multi-Powerwall systems must be floor-mounted and must be anchored to an adjacent wall. The
wall must be capable of supporting the lateral load of the Powerwall stack.
A maximum number of 3 floor-mounted Powerwall units may be joined together with two Powerwall Stack
Kits. For systems with more than 3 Powerwalls, separate groups of 3 units should be assembled, with each
group of 3 attached to a wall.
