Solar Production is Higher or Lower Than Expected
On the landing page, the solar production does not meet expectations (solar value is zero, or is higher or lower than expected)
Symptoms
On the landing page, the solar production does not meet expectations (solar value is zero, or is higher or lower than expected).
Steps to Troubleshoot
- Verify all meters are online and communicating.
- If a Gateway meter is not online, see Gateway Meters Do Not Appear for troubleshooting steps.
- Ensure CT(s) have been placed in the correct location and are measuring the
correct conductor(s):
- Verify the CT is clamped properly
around the intended conductor(s). WarningBefore 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.
- Verify the CT is not capturing any
other conductor(s).NoteIf a site has multiple inverter outputs and their conductors are being grouped, ensure every conductor is captured.
- Verify the CT is clamped properly
around the intended conductor(s).
- Confirm the inverter is currently producing; if the inverter production is not 0
but is not meeting the expected output, the issue is not with Powerwall.
Troubleshoot the solar DC and AC connections, then troubleshoot the inverter
production with the manufacturer.
- For Tesla Solar Inverter,
use the Solar Inverter Configuration Interface or measure with a multimeter.NoteFor Tesla Solar Inverter without a Site Controller (all Tesla P/Ns except 1538000-45-y), commissioning is performed in the Configuration Interface rather than in Setup App. See Configure Tesla Solar Inverter Using the Configuration Interface for more information.
- For a third party inverter, check solar production using the display on the inverter itself (if present), the inverter production monitoring app, or a multimeter.
