1What the error means
The inverter detected an excessively high DC component in the current it feeds into the grid. The standard requires immediate disconnection in order to protect the grid transformers.
2Possible causes
- Fault in the power bridge (IGBT) or the capacitors
- Fault in the current measuring circuit
3What to do
- Restart the inverter once.
- If the code returns, it is an internal fault and repair in our lab is required.
