Operating Manual
W 343 AcVtglim
1
The master disconnects from
the external energy source
because the voltage at
connection AC2 is too high
or the battery voltage too
low.
• Contact the SMA Service Line if required.
W 344 AcVtglimSlv1
1
Slave 1 disconnects from the
external energy source
because the voltage at
connection AC2 is too high
or the battery voltage too
low.
W 345 AcVtglimSlv2
1
Slave 2 disconnects from the
external energy source
because the voltage at
connection AC2 is too high
or the battery voltage too
low.
W 347 ExtOverload
1
The master disconnects from
the utility grid due to line
conductor failure/overload
at connection AC2.
• Reduce the total power of the loads, e.g.,
by staggering their use over time.
•
Ensure that there is not a short circuit
present at connection AC2.
W 348 ExtOverloadSlv1
1
Slave 1 disconnects from the
utility grid due to line
conductor failure/overload
at connection AC2.
W 349 ExtOverloadSlv2
1
Slave 2 disconnects from the
utility grid due to line
conductor failure/overload
at connection AC2.
W 351 ExtScirDet
1
There is a short circuit
present at connection AC2
of the master.
•
Eliminate the short circuit.
W 352 ExtScirDetSlv1
1
There is a short circuit
present at connection AC2
of slave 1.
W 353 ExtScirDetSlv2
1
There is a short circuit
present at connection AC2
of slave 2.
W 355 PhsAngErr
1
Assignment of the line
conductors of the external
energy source to the AC2
connections of the
Sunny Island does not result
in a right-rotating magnetic
field.
•
Ensure that the master is connected to L1,
slave 1 to L2, and slave 2 to L3.
