CT placement locations include the following:

Site (Grid): A CT is placed between the utility meter and main switch to measure both load and generation. See Appendix F: Feature Notes for information on implementing a Site Limit to curtail Powerwall charging from the grid.

Solar: If the site includes solar equipment, a CT is placed after the solar inverter to measure the solar output.

Load: Site and solar metering are preferred. However, in configurations where it is not possible to locate CTs between the utility meter and the main switch, load metering can substitute for site metering.

Conductor: Where desired to curtail Powerwall discharge on a conductor, a dedicated Conductor Limit CT can be installed. This feature is optional for installations. See Appendix F: Feature Notes for more information.

See Appendix C for system wiring diagrams depicting CT placement for various wiring configurations.
