NOTICE Using three-phase consumers in backup operation
Damage to components/devices!
Do not switch on any three-phase (polyphase, high-voltage) electrical con-
sumers during backup operation. These consumers may be damaged be-
cause the Backup-Box only supplies electricity on one phase.
4.1 Function
A storage system with Backup-Box automatically switches from grid to backup operation
(and vice versa). The two operating modes are described in the following.

In grid operation the consumers in the building (4 - 6) are connected to the public elec-
trical mains. All consumers in the house are supplied with electrical power. The storage sys-
tem controls - as described in the product documentation of the storage system - the en-
ergy flows in the building.

3 Backup-Box 9 Public electrical mains
4 Consumer connected to phase L1
5 Consumer connected to phase L2
6 Consumer connected to phase L3
The Backup-Box (3) automatically detects a grid outage. As soon as the voltage of the
electrical mains drops to approx. 180V, the connection to the public electrical mains (9)
and to the PV system (7) is disconnected.
Backup power is generated after approx. 3 seconds. In this case, the direct current of the
battery of the storage system (8) is converted into alternating current using the inverter of
the Backup-Box (2). The consumers connected to the phase L1 in the house (4) are thereby
supplied with electrical power. Consumers connected to the phase L2 (5) or L3 (6) will not
be supplied with electrical power.
The sonnen Eclipse (light ring) of the storage system switches off as soon as the backup
operation starts. The sonnen Eclipse of the Backup-Box illuminates white during backup
operation.
The storage system with Backup-Box switches from backup to grid operation as soon as
the public electrical mains (9) start to deliver electrical power again.
Automatic stop of the backup operation
The storage system with Backup-Box generates electrical power until a minimum state of
charge of the battery is reached. Thereafter, no further discharge is allowed.

Operation | 4
KD-493 | 22324 | EN | X01 11 / 20
4.1.3 Backup operation - overload behaviour
The control of the storage systems protects the entire system against overload by stop-
ping the backup operation in special overload cases. The sonnen Eclipse of the storage sys-
tem signals this state by pulsing orange, the sonnen Eclipse of the Backup-Box switches off
as soon as the backup operation stops.
The storage system restores the backup operation as soon as the overload is no longer
present. If the backup operation was successfully restored, the sonnen Eclipse of the stor-
age system switches off and the sonnen Eclipse of the Backup-Box starts lighting up white
again.
