9 Troubleshooting SMA Solar Technology AG
52 SI60H-80H-BE-en-20 Operating Manual
W 339 ExtVtgIncPro 1 Voltage rise protection •
Ensure that the conductor cross-section of
the AC cables is correctly sized.
W 340 ExtVtgIncProSlv1 1
W 341 ExtVtgIncProSlv2 1
W 343 AcVtglim 1 The master disconnects from
the external energy source
because the voltage at
terminal 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
terminal 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
terminal 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 terminal 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 terminal AC2.
W 348 ExtOverloadSlv1 1 Slave 1 disconnects from the
utility grid due to line
conductor failure/overload
at terminal AC2.
W 349 ExtOverloadSlv2 1 Slave 2 disconnects from the
utility grid due to line
conductor failure/overload
at terminal AC2.
W 351 ExtScirDet 1 There is a short circuit
present at terminal AC2 of
the master.
•
Eliminate the short circuit.
W 352 ExtScirDetSlv1 1 There is a short circuit
present at terminal AC2 of
slave 1.
W 353 ExtScirDetSlv2 1 There is a short circuit
present at terminal AC2 of
slave 2.
W 355 PhsAngErr 1 Assignment of the line
conductors of the external
energy source to the AC2
terminals 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.
