Powerwall 3 is Discharging at Full Power
Powerwall 3 is discharging at its maximum discharge, and the site reading increases as Powerwall 3 discharges
Steps to Troubleshoot
- If using external Site CTs:
- Confirm the CTs are
facing the correct way:
- Locate the CT(s) used to measure the source that is displaying incorrect power flow readings.
- Verify the CT(s) are oriented such
that the label is facing toward the source (away from the breaker).
- Solar Current Transformer: Label toward the Inverter
- Site Current Transformer: Label toward the Grid

- Confirm the CTs are
measuring the correct phase:
- Locate the CT on the Meter page in Tesla One.
- Determine which phase the CT should be measuring.
- Verify the CT is measuring the
correct phase.
Figure 2. Gateway CT Measuring Correct Phase (top) and Incorrect Phase (bottom) NoteIn the examples above, the CT is monitoring a solar inverter conductor, which is why only (1) CT is required.
- Confirm the CTs are
facing the correct way:
- For systems with Backup Gateway
2 or Gateway 3, verify the supply
conductors feeding the Gateway are connected to the Supply terminals:
- Verify any backup conductors are connected to the
Backup terminals (or the internal panelboard if it is connected to the Backup
terminals):
