Install Tesla 100 A CTs

Warning
Before installing, disconnecting, and/or adjusting CTs, ensure the circuits being measured are not energized and the system is completely powered down. Failure to de-energize the system may compromise operator and equipment safety.
  1. Plug the Tesla 100 A CT into the terminal in the Backup Gateway. Ensure the connector is fully seated in the terminal.
  2. Clamp the CT around the conductor to be measured.

Tips

  • When metering split-phase 240 V solar inverters, a single CT on L1 or L2 can be used to meter solar production.
  • The CT1 and CT2 terminals have voltage references to L1 and L2 respectively and cannot be reconfigured. The CT3 terminal has a default voltage reference to L1 but can be configured as L2 during device setup.
  • Ensure CTs are facing the proper direction as indicated on the label. A CT will show negative current if installed backwards.
  • The Powerwall installer has the option to set a Conductor Export Limit, or a Site Charge Limit. When used, the Powerwall will dynamically curtail to meet these site-specific programmed thresholds. See Appendix G: Feature Notes for more information.
