STATE 233

Undervoltage on L3

Behaviors

Grid conditions are being tested and as soon as they are within the permissible range again, the inverter will resume feeding energy into the grid.

Status Code Class 2

Class 2 status codes (state codes that start with a two, i.e., 2xx), may occur while feeding energy into the grid, but generally do not cause the process to be interrupted permanently.

The inverter temporarily disconnects automatically from the grid, the grid is then monitored as specified and the inverter attempts to resume feeding energy into the grid.

Solutions for this Error

Remedies

  • Check AC breakers and switches are in the ON position. Check mains AC voltage and frequency at the inverter clamps (Qualified persons only). This error should automatically clear once the grid is back within an acceptable range. If the grid is within operating parameters and this error persists, the device may have an internal failure.
  • If this issue persists, the next steps include inspecting internal inverter components and their cabling by a trained Fronius Service Provider to further diagnose this specific issue. Defective components or the device itself may need to be replaced.
