Installation & Compatibility

Confirm the complete Powerwall part number before ordering. Earlier Powerwall 3 revisions use different accessory kits, and Tesla specifies that the MPPT jumper types are not interchangeable. Install components according to the instructions for the matching Powerwall revision, including ferrite placement, conductor routing, and front cover fastening.

💡 Planning Tip: Check the Powerwall identification label when selecting an accessory kit. The full model and revision number determines which kit and MPPT jumpers the installation requires.
