Solutions for this Error

Remedies

  • Power Cycle the Inverter. To do so, both the DC and AC power sources must be disconnected to allow the device to discharge. Once the device has had time to discharge, turn on both the AC and DC power sources to the inverter.
  • 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.
