3 < Grid fault >
The average grid voltage over 10 minutes
is no longer within the permissible range.
This can have the following causes:
• The grid voltage at the connection
point of the Sunny Boy is too high.
• The grid impedance at the
connection point of the Sunny Boy is
too high.
The Sunny Boy disconnects from the grid to
assure compliance with the voltage quality.
• Check the grid voltage at the
connection point of the Sunny Boy.
If due to local grid conditions the grid
voltage exceeds the configured limiting
value, ask the utility operator whether the
voltage can be adjusted at the feed-in
point, or whether he will agree to a
modification of the limiting value for
voltage quality monitoring.
If the grid voltage is continually within the
acceptable range, and this error is still
displayed, contact the SMA Service Line.
4 < Grid fault >
The Sunny Boy stop feeding in due to grid
fault. • Check the grid connection for strong,
short-term frequency variations.
5 < Grid fault >
The grid frequency is not within the
permissible range. For safety reasons, the
Sunny Boy disconnects itself from the grid. • If possible, check the grid frequency
and observe how often major
deviations occur.
If repeated frequency variations occur and
as a result this error occurs, ask the grid
operator if he agrees to a modification to
the operating parameter.
Discuss the proposed parameters with the
SMA Service Line.
6 < Grid fault >
The internal inverter monitoring has
detected an impermissibly high proportion
of direct current in the grid current. • Check the grid connection for direct
current.
• If this is a recurrent phenomenon,
check with the grid operator whether
it is possible to raise the limiting value
of monitoring.
7 < Frequency not permitted >
The grid frequency has left the allowable
range. For safety reasons, the Sunny Boy
disconnects itself from the grid. • If possible, check the grid frequency
and observe how often major
deviations occur.
If repeated frequency variations occur and
as a result this error occurs, ask the grid
operator if he agrees to a modification to
the operating parameter.
Discuss the proposed parameters with the
SMA Service Line.
