Event number
Message, cause and corrective measures
3501
Insulation resistance > Check generator
The inverter has detected a ground fault in the PV array.
Corrective measures:
3601
High discharge curr. > Check generator
The leakage currents of the inverter and the PV array are 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. If this process hap-
pens five times a day, the inverter disconnects from the utility grid and termi-
nates feed-in.
Corrective measures:
3701
Resid.curr.too.high > Check generator
The inverter has detected a residual current due to temporary grounding of the
PV array.
Corrective measures:
3801 to 3802
DC overcurrent > Check generator
Overcurrent at the DC input. The inverter briefly interrupts feed-in operation.
Corrective measures:
3901 to 3902
Waiting for DC start conditions > Start cond. not met
The feed-in conditions for the utility grid are not yet fulfilled.
Corrective measures:
4301
Serial el.arc in String detected by AFCI mod.
The inverter has detected an electric arc. The inverter interrupts grid feed-in
and cannot connect to the utility grid.
Corrective measures:
Installation Manual
• Check the PV system for ground faults (see Section 10.5, page 55).
• Check the PV system for ground faults (see Section 10.5, page 55).
• Check the PV system for ground faults (see Section 10.5, page 55).
• If this message is displayed frequently, ensure that the PV array has been
correctly rated and wired.
1. Wait for higher irradiation.
2. If this message is displayed frequently in the morning, increase the
voltage limit for starting grid feed-in. Change the parameter Minimum
voltage input or A.VStr, B.VStr.
3. If this message is displayed frequently with medium irradiation, ensure
that the PV array is correctly rated.
• Reset the operation inhibition (see Section 10.6, page 57).
