Event 6202

Event message:

• Self-diagnosis

• Interference device

Explanation:

The inverter reports Self-diagnosis or Interference device and the red LED lights up. This indicates a disturbance in the device-internal residual current monitoring unit (RCMU, RCD) of the inverter. When the error occurs, the inverter discontinues feed-in.

Corrective measures:

• If the message occurs only briefly when starting up or shutting down the inverter, no further action is required. In this case, the cause may be the fluctuating PV power in the lower power range.

• If the message occurs rarely or after a firmware update, no further action is required.

• If the message is permanently present, the assembly or inverter needs to be replaced.
