ToU internal errors: INTERNAL EXTRACT

Written by Maximilian Kraft

Errors

  • INTERNAL_EXTRACT_HYBRID_INVERTER_BATTERY_CONSTRAINT

  • INTERNAL_EXTRACT_DRIVER_CONSTRAINTS

  • INTERNAL_EXTRACT_DRIVER_CONSTRAINTS_BATTERY

  • INTERNAL_EXTRACT_DRIVER_CONSTRAINTS_HEAT_PUMP

Cause of issue

Unreliable measurement cause our API to not report any driver constraints. This can also be caused in case the asset is offline.

Assets showing the errors

Following hybrid & battery inverters cause the errors:

  • Sungrow SH10.0RT-V112

  • Sungrow SH15T-V11

  • Sungrow SH5.0RT-V112

  • Sonnen ECO_8-10

  • Enphase Envoy S

Manual action to resolve the error

  • Ensure all assets are online

  • Trigger a rescan of the gridBox. (In case of a specified asset within the error delete the asset before initiating a rescan)

Status

Update 15.05.2025:

Fixes are being implemented. We reworked the offline asset check, and now detect assets correctly as offline, which turned out to be the underlying issue for this error in some cases. Next, we are working on introducing caching for asset limits to increase robustness for momentarily missing asset limits.
