Powerwall Stack Kit Installation Manual
Step 2: Choose a Wiring Option
In multi-Powerwall systems, communication wiring is daisy-chained between Powerwall units.
Power wiring is direct (home run) from each Powerwall to a dedicated circuit breaker in the
electrical panel. Wiring between Powerwalls can be concealed, or run externally.
Concealed Wiring
For concealed wiring, a hole is drilled from the front of the first Powerwall into its wiring
compartment and wires are run directly into it from the back port of the second Powerwall. To
use this wiring method, proceed to Step 3, “Prepare for Concealed Wiring.”
External Wiring
For external wiring, wires are run through conduit or raceway that spans the wiring
compartment ports on the side of each Powerwall. To use this wiring method, skip to Step 4,
“Join the Powerwall Units.”
Step 3: Prepare for Concealed Wiring
NOTE: If you are running wires between the wiring compartments through external conduit,
skip to Step 4, “Join the Powerwall Units.”
1. Disconnect all wiring from the wiring compartment of the first Powerwall.
2. Locate the wiring interface cover and peel back the film to expose the adhesive on the
cover gasket. With the gasket facing inward, place the cover over the interface board at the
back of the wiring compartment. The cover is intended to protect the circuit board and its
components from metal shavings while drilling into the wiring compartment.
