Commission the System

  1. Turn off any solar inverter(s) prior to commissioning. Turning off solar production ensures CT function can be confirmed as all CT measurements should be positive when there is no solar.
  2. Confirm the breaker feeding the energy meter has been turned on.
  3. Follow the standard procedure to commission Wall Connector in Tesla Pros (see Wall Connector Device Setup in Tesla One for complete instructions).
  4. Ensure Wall Connector has been updated to firmware version 25.42.1 or greater. If Wall Connector is not connected to Wi-Fi, follow the offline firmware updates procedure.
  5. Once connected, the energy meter will automatically be detected. Select Meter to configure CTs and set the Max Conductor Limit.
  6. Select the energy meter to configure the CTs.
  7. For each of the connected CTs, select the CT and set the Location to Conductor.
  8. On the Meter screen, set the Max Conductor Limit. This value should be 80% of the electrical panel’s rated limit.
    • See Overview for circuit breaker size options and the associated max conductor current ampacity for each circuit breaker size.
    • For example, the max conductor current ampacity for a 60A breaker would be 48A.
  9. Test the system by turning on large loads in the panel and ensuring Wall Connector properly adjusts its charge rate. Alternatively, temporarily set the max conductor current lower than the actual limit of the electrical panel being measured. For example, if the conductor limit is 50A, temporarily set it to 32A. Confirm that this current limit is maintained by the Wall Connector by turning on some loads that would exceed the limit.
