< Grid frequency disturbance >
The grid frequency is outside the permitted
range. For reasons of safety, the Sunny Boy
disconnects itself from the grid.
•
If possible, test the grid frequency
and the frequency of major
fluctuations.
If repeated deviations occur and this is
causing these errors, ask the grid
operator if they agree to a modification
of the operating parameters.
Discuss the proposed parameters with
the SMA Technical Service Line.
6
< DC grid feeding >
The internal inverter monitoring has
detected an excessively high direct current
component in the grid current.
•
Check the grid connection for the
DC component.
•
If this event occurs frequently,
discuss with the utility operator
whether the monitoring threshold
can be raised.
7
< Grid frequency not permitted >
The grid frequency is outside the permitted
range. For reasons of safety, the Sunny Boy
disconnects itself from the grid.
•
If possible, test the grid frequency
and the frequency of major
fluctuations.
If repeated deviations occur and this is
causing these errors, ask the grid
operator if they agree to a modification
of the operating parameters.
Discuss the proposed parameters with
the SMA Technical Service Line.
8
< Grid failure >
Waiting for grid voltage.
•
Check fuse.
•
Check AC installation.
•
Check whether there is a general
power failure.
9
< PE connector missing >
•
Check AC installation.
•
Connect the PE cable to the AC
terminal as described in section 6.2
„Connection to the Public Grid
(AC)” (Page 28).
10
< L and N swapped >
•
Correct the connection as
described in section 6.2
„Connection to the Public Grid
(AC)” (Page 28).
