11.4.3 Error Number 34xx to 40xx ‒ Disturbance on the PV Array
1301 Left rotating magnetic field is connected. 30 s A ‒ • Check phase position.
• Make sure all fuses are switched
on.
1500 The grid engagement conditions are not
achieved again after a grid error.
W W ‒ • Check power frequency and line
voltage.
* Depending on the parameterization, the error message must be acknowledged manually.

3403 The voltage of the PV generator is too high. 15 min 30 min ‒ • Check the DC input voltage.
• Check the module wiring and
plant design.
3404 Open-circuit voltage is too high. Fault
detected by standard monitoring.
15 min 30 min ‒
3406 The active power is too high due to the
electrical voltage of the PV generator
being too high.
15 min 30 min ‒
3501 The insulation monitoring device has
measured an excessively low insulation
resistance.
For the options "GFDI and insulation
monitoring device" and "Advanced
Remote GFDI and insulation monitoring
device", the insulation monitoring device is
only active when the GFDI or the
Advanced Remote GFDI is open.
C C ‒ • Check the PV array for
insulation errors.
3502 The GFDI has tripped. C C ‒
3504 The insulation monitoring device has
detected an insulation error. Since the
parameter IsoErrIgn is set to On, this error
is ignored.
W W ‒
3507 A ground fault has occurred on the
ungrounded pole of the PV array.
A A ‒
3510 The inverter has found an insulation error
on the inverter bridge.
A A ‒
3511 The Advanced Remote GFDI has detected
a temporary ground fault.
‒ ‒ ‒
3512 The Advanced Remote GFDI has detected
a permanent ground fault.
A A ‒
3517 Insulation measuring will be performed. W W ‒ ‒
