Tesla, Powerwall 2m Expansion Harness, 1875157-20-y

Item Weight: 6.7108 lb

The Tesla Powerwall 3 Expansion Harness 2m (1875157-20-y) is a 2-meter, factory-engineered cable designed to link Tesla Powerwall 3 units to DC expansion packs. It enables parallel installation for increased storage capacity by linking the high-voltage DC circuits between a leader Powerwall 3 and up to three additional expansion units.

Key Details:

  • Purpose: Connects expansion packs to a lead Powerwall 3 (not for Powerwall 2).
  • Length: 2 meters (6.56 feet).
  • Components: Includes high-voltage Tesla connectors, DC jaws, and a T40 harness screw for secure, weather-resistant attachment.
  • Compatibility: Must be used with Powerwall 3 units (P/N 1707000-xx-J or higher).
  • Installation: Requires certified Tesla installers; connects to either side of the unit to allow for flexible, side-by-side or stacked configurations.

This harness is essential for expanding the system beyond the base 13.5 kWh of a single unit, facilitating up to 54 kWh of total storage with one leader and three expansion packs.
