9 Troubleshooting
Fault
Possible causes
Rectification
Grid operation (no grid outage)
The electrical consumers in the
building are not supplied with energy
in grid operation.
The mains cables (AC lines) have not
been correctly connected.
Check the electrical wiring of the mains
cables (see Connecting the mains cables
[P. 24]).
The F1.B miniature circuit breaker in
the Backup-Box is switched off.
Switch on the F1.B miniature circuit
breaker inside the Backup-Box .
Backup operation (grid outage) - Backup operation does not start
Backup operation doesn’t start. The
sonnen Eclipse of the storage sys-
tem and the Backup-Box is
off.
The batteries of the storage system
have discharged so much that further
discharging would lead to a deep dis-
charge state and therefore damage
the batteries.
The only thing to do is wait until the grid
outage passes, the public electrical grid
once again starts supplying electrical en-
ergy and the Backup-Box automatically
switches to grid operation.
The storage system is switched off.
Switch on the storage system.
Backup operation doesn’t start. The
sonnen Eclipse of the storage sys-
tem pulses
orange.
The sonnen Ec-
lipse of the Backup-Box is
off.
Electrical consumers with too high
power consumption are connected to
phase L1.
Switch off electrical consumers or re-
duce their power consumption.
Only connect electrical consumers to
phase L1 when they have a power con-
sumption that does not exceed the
nominal power or (when switching on)
the maximum power of the Backup-Box .
Backup operation doesn’t start. The
sonnen Eclipse of the storage sys-
tem illuminates
red.
The sonnen Ec-
lipse of the Backup-Box is
off.
The storage system has detected a
problem.
Please contact the sonnen service team
to get help resolving the problem.
Backup operation (grid outage) - Backup operation stops
Backup operation stops. The sonnen
Eclipse of the storage system and
the Backup-Box is
off.
The batteries of the storage system
have discharged so much that further
discharging would lead to a deep dis-
charge state and therefore damage
the batteries.
The only thing to do is wait until the grid
outage passes, the public electrical grid
once again starts supplying electrical en-
ergy and the Backup-Box automatically
switches to grid operation.
Backup operation stops. The sonnen
Eclipse of the storage system pulses
orange.
The sonnen Eclipse of the
Backup-Box is
off.
The control of the storage system de-
tected an overload, this means there
are electrical consumers connected to
phase L1 with a too high power con-
sumption.
Switch off electrical consumers so that
the power consumption does not ex-
ceed the nominal power or (when
switching on) the maximum power of
the Backup-Box .
The storage system automatically re-
starts the backup operation as soon as
the overload is no longer present.
Backup operation doesn’t stops. The
sonnen Eclipse of the storage sys-
tem illuminates
red.
The sonnen Ec-
lipse of the Backup-Box is
off.
The storage system has detected a
problem.
