The Tesla RS-485 Harness for Tesla Remote Meter (2045794-00-D) provides the wired communication connection between a Tesla Remote Meter (TRM) and the controller in a compatible Powerwall 3 system. It carries metering data used by the system to monitor the electrical circuits assigned to the remote meter.
The harness features a meter-side RS-485 connector and individual connection leads for the controller interface. Tesla specifies a nominal length of 1.2 meters (approximately 4 feet) for this harness family. This is a communication accessory—not an AC power-supply harness, current-transformer extension, or battery expansion cable.

Confirm Tesla P/N 2045794-00-D against the installation requirements before ordering. This is a Tesla Remote Meter accessory, not a universal RS-485 adapter or a replacement for Neurio meter accessories. In the supported Powerwall 3 arrangement, the harness connects to Powerwall 3—not directly to the communication connector on Backup Switch or Gateway 3.
Hardware revision note: Tesla identifies harness revisions 2045794-10-A and later as including a ground wire. Do not assume that this 2045794-00-D harness has the same grounding arrangement as later versions; verify the required revision and applicable wiring instructions.
After installation, the wired meter must be detected and configured through the Tesla One commissioning process. The installer should confirm the meter’s assigned measurements and verify that its readings are consistent with the installed current transformers and system configuration.
