Tesla Powerwall – 1875157-20-C – Harness 2M, PW3 Expansion

Tesla Powerwall 3 — 2 Meter Expansion Harness

Connect your Powerwall 3 Expansion system with the Tesla 2 m Expansion Harness. This cable connects a compatible Powerwall 3 to an Expansion unit, or links two Expansion units.

Its longer reach accommodates wall-mounted layouts requiring more separation between units, while factory connectors provide dedicated DC power and communication connections.

This listing includes one harness only. Powerwall equipment, mounting kits, and cable-management straps are separate.

• Extended Reach: 2-meter cable for approved wall-mounted Expansion layouts.
• Factory Connections: Purpose-built connectors at both ends.
• Durable Jacket: TPE construction resists moisture, UV exposure, and flame.
• Indoor or Outdoor Use: Suitable when installed according to Tesla requirements.

Typical Applications

• Connecting wall-mounted Powerwall 3 Expansion equipment.
• Replacing a damaged harness.
• Accommodating revised equipment spacing in an approved installation.
