Connection of the
generator is locked as a
result of too many
interrupted start
processes.
• Ensure that the generator triggering is functioning,
the generator starts, and there is constant and stable
generator voltage present at connection AC2.
• To re-enable connection of the generator,
acknowledge the generator error (see Section 9.2
"Acknowledging Errors", page 42).
A warm-up time 234.12 GnWarmTm that is too short
may have been configured and hence the generator is
unable to supply valid voltage.
• Ensure that the generator warm-up time is configured
appropriately (see the Sunny Island inverter
installation manual).

AC sources in the stand-alone grid are
performing undesired feed-in to the utility
grid. The reverse power to the utility grid has
been exceeded for too long.
• Contact the SMA Service
Line, if required.

W 505 GdCurNomExceed 1
The feed-in current of the master is greater
than 232.04 GdCurNom.
• Contact the SMA Service
Line, if required.
W 506 GdCurNomExcSlv1 1
The feed-in current of slave 1 is greater than
232.04 GdCurNom.
W 507 GdCurNomExcSlv2 1
The feed-in current of slave 2 is greater than
232.04 GdCurNom.

Internal transfer relay in the
master does not open.
A bypass switch may have bridged the internal
transfer relay.
• Ensure that the bypass switch is in the
position for operation with the
Sunny Island.
•
Ensure that the connections AC1 and
AC2 are not bridged.
W 606 TransfNotOpnSL1 1
Internal transfer relay in
slave 1 does not open.
W 607 TransfNotOpnSL2 1
Internal transfer relay in
slave 2 does not open.
