Powerwall / Powerwall+ is Charging from Grid Rather than Available Solar​​​​​​​​​​​​​​

Powerwall / Powerwall+ is charging from the grid even though solar production is present

Steps to Troubleshoot

  1. On the Device page, confirm a solar inverter is present.
  2. On the Metering page, confirm a Solar CT is assigned.
  3. Confirm the CTs are facing the correct way:
    1. Locate the CT(s) used to measure the source that is displaying incorrect power flow readings.
    2. Verify the CT(s) are oriented such that the label is facing toward the source (away from the breaker).
      1. Solar Current Transformer: Label toward the Inverter
      2. Site Current Transformer: Label toward the Grid

Note
Powerwall / Powerwall+ charging from the grid rather than solar is expected behavior when the home is in the path of a national weather advisory. See the Storm Watch mobile app page on tesla.com for more information about how your system operates when in Storm Watch mode.
