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 3-phase solar inverters, install CTs on L1, L2, and L3 output of the solar inverter AC circuit.

    Note
    A single CT can be installed on L1 and connected to CT1 port to measure the solar power from a 3-phase solar inverter. Make sure to toggle 1CTx3 button to the ON position when configuring the CT during commissioning; the software triples the power measured by the CT. To ensure that the total power output calculated by software is correct, the solar power must be converted by a balanced 3-phase solar inverter, which distributes power evenly between the three phases.
  • Ensure CTs are facing the proper direction as indicated on the label. A CT will show negative current if installed backwards.
