Tesla Remote Energy Meter is
connected to the system Site Controller wirelessly (any Site
Controller) or via an RS-485 wiring harness (Powerwall 3 or Backup
Gateway 2 only).
At the time of publication, Tesla Remote Energy Meter has (3) CT terminals:
CT4 functionality will be available at a later date.

The Remote Energy Meter functions
by measuring voltage (by voltage tap) and current (by Current
Transformer, or CT) at certain points in the system. For the meter
to function correctly, the following are critical:
The Remote Energy Meter
voltage line harness leads must be connected to the
correct phases
The CTs
must be placed around conductors of the correct
phase:
CT1 = L1
CT2 = L2
CT3 = L2
Install the Tesla Remote Energy Meter and CTs
describes how to perform these steps correctly, but the following
diagrams illustrate some high level correct and incorrect meter / CT
installations.

and CT InstallationFigure 3. Incorrect CT
Installation - CTs are Measuring Incorrect PhasesFigure 4. Incorrect
Meter Installation - Main Breaker Swapped Busbar Phases,
Resulting in Voltage Line Harness Being Wired

Meter Installation - Installer Skipped a Breaker Pole,
Resulting in Voltage Line Harness Being Wired
