Event number Display message, cause and corrective measures
3401 to 3402 DC overvoltage > Disconnect generator
Overvoltage at the DC input. This can destroy the inverter.
Corrective measures:
• Immediately disconnect the inverter from all voltage sources (see
Section 2.2, page 7).
• Check whether the DC voltage is below the maximum input voltage of
the inverter. If the DC voltage is below the maximum input voltage of the
inverter, reconnect the DC connectors to the inverter.
• If the DC voltage is above the maximum input voltage of the inverter,
ensure that the PV array has been correctly rated or contact the installer
of the PV array.
• If this message is repeated frequently, contact the Service.
3501 Insulation resist. > Check generator
The inverter has detected a ground fault in the PV array.
Corrective measures:
• Check the PV system for ground faults (see Section 5, page 18).
3601 High discharge curr. > Check generator
The leakage current from the inverter and the PV array is too high. There is a
ground fault, a residual current or a malfunction.
The inverter interrupts feed-in operation immediately after exceeding a thresh-
old and then automatically reconnects to the utility grid.
Corrective measures:
• Check the PV system for ground faults (see Section 5, page 18).
3701
Resid.curr.too.high > Check generator
The inverter has detected a residual current due to temporary grounding of the
PV array.
Corrective measures:
• Check the PV system for ground faults (see Section 5, page 18).
3801 to 3802 DC overcurrent > Check generator
Overcurrent at the DC input. The inverter briefly interrupts feed-in operation.
Corrective measures:
• If this message is displayed frequently, ensure that the PV array has been
correctly rated and wired.
