2 Safety
2.1 Intended use
The sonnenBackup-Box is an emergency power unit designed to supplement the
sonnenBatterie eco 8.0 or hybrid 8.1. The Backup-Box - in conjunction with the
appropriate storage system of the sonnen GmbH - serves to supply power in the
event of a power failure. Any other use is considered improper use.
Improper use poses a risk of death or injury to the user or third parties as well as
damage to the product and other items of value. The following points must there-
fore be observed in order to comply with the intended use of the product:
• Only operate the Backup-Box together with the right storage system.
• The Backup-Box must be installed by an authorised electrician.
• The Backup-Box must only be connected to the storage system as described
here.
• Isolated operation is not possible with the Backup-Box. A generator (e.g. a PV
system) must never be connected after the output of the Backup-Box.
• Intended use includes observing this document as well as all accompanying
product documentation of the appropriate storage system.
• The Backup-Box must only be used at suitable installation location.
• The transport and storage conditions must be observed.
Especially the following uses are not permissible:
• Operation in flammable environments or areas at risk of explosion.
• Operation in locations at risk of flooding.
• Operation outdoors.
Failure to comply with the conditions of the warranty and the information
specified in this document invalidates any warranty claims.
2.2 Requirements for the electrician
Improper installation can result in personal injury and/or damage to components.
For this reason, the Backup-Box must only be installed and commissioned by au-
thorised electricians. Authorised electricians must meet the following criteria:
• The electrician must be a person with a technical knowledge or sufficient ex-
perience to enable him/her to avoid dangers which electricity may create.
• The company for which the electrician works must be certified by sonnen
GmbH.
• The electrician must have successfully complete sonnen GmbH certification
training for the product.
2.3 Operating the Backup-Box
Incorrect operation can lead to injury to yourself or others and cause damage to
property.

2 | Safety
6 / 20 Operating instructions sonnenBackup-Box
• The Backup-Box must only be operated as described in the product document-
ation.
• This device can be used by children from the age of eight (8) years old and in-
dividuals impaired physical, sensory or mental capabilities or individuals with
limited knowledge and/or experience of working with the device, as long as
they are supervised or have been trained to safely use the device and under-
stand the resulting risks of doing so. Children must not play with the device.
Cleaning and user maintenance must not be carried out by children without su-
pervision.
2.4 Product modifications or changes to the product
environment
• The Backup-Box must only be used in its original state without any user modi-
fications and only when in perfect working order.
• Safety devices must never be overridden, blocked or tampered with.
• The interfaces of the Backup-Box and the storage system must be wired in ac-
cordance with the product documentation.
• All repairs on the Backup-Box must be performed by authorised service tech-
nicians only.
2.5 Voltage inside the Backup-Box
5 min
The Backup-Box contains live electrical parts, which poses a risk of electrical
shock. The Backup-Box and storage system inverter also contain capacitors which
carry voltage even after the storage system is switched off.
Therefore:
Do not open the Backup-Box.

NOTICE Using three-phase consumers in emergency operation
Damage to components/devices!
Do not switch on any three-phase (polyphase, high-voltage) electrical
consumers during emergency operation. These consumers may be dam-
aged because the sonnenBackup 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 follow-

In grid operation the consumers in the building (4 - 6) are connected to the pub-
lic electrical mains. All consumers in the house are supplied with electrical power.
The storage system controls - as described in the product documentation of the
storage system - the energy flows in the building.

4 Consumer connected to phase L1

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 elec-
trical mains (9) and to the PV system (7) is disconnected.
Backup power is generated after approx. 3 seconds. In this case, the direct cur-
rent 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 con-
nected to the phase L2 (5) or L3 (6) will not be supplied with electrical power.
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 al-
lowed.

5 Switching off the Backup-Box
To switch off the Backup-Box manually, the following procedure can be carried
out. In order to be able to work on the Backup-Box safely it must be disconnec-
ted from the power supply (see next section).
1. Disconnect the power supply to the storage system as described in the relev-
ant product documentation.
2. Wait at least five minutes until the internally stored energy inside the storage
system inverter has discharged.
NOTICE Deep-discharge of the battery modules
Destruction of the battery modules!
Do not disconnect the storage system from the public grid for long peri-
ods of time.
Never continue to operate battery modules which have been deep-dis-
charged.

6 Maintenance and Cleaning
6.1 Checking function
The backup circuit is equipped with a residual current device (RCD). The function
of the RCD can be tested by pressing the test key T. After pressing, the RCD
must switch off (the backup circuit is interrupted).
Maintenance interval Action to be taken
Every 6 months Check the function of the RCD with help of the
Test key.
Table2: Checking function
6.2 Cleaning
NOTICE Use of unsuitable cleaning agent and/or excessive water
Material damage because of scratched surfaces and/or damage caused by
penetration of water!
Do not use scouring cloths, sponges or cleaning agents.
Take particular care when cleaning the LED ring, since it can easily be
scratched.
Use only moist cloths, not wet cloths.
Do not use water jets.
Carefully clean the outside of the Backup-Box with a clean, moist cloth. For

8 Troubleshooting
Grid operation - no grid outage
Fault Possible causes Rectification
The electrical consumers in
the building are not supplied
with energy in grid opera-
tion.
The mains cables (AC lines)
have not been correctly
connected.
Contact your installer to
check the electrical wiring.
The F1.B miniature circuit
breaker in the Backup-Box is
switched off.
Contact your installer to
check if the F1.B miniature
circuit breaker is switched
on.
Backup operation - grid outage
Fault Possible causes Rectification
The Backup-Box is not sup-
plying electrical energy to
the consumers connected
to phase L1.
The batteries of the storage
system have discharged so
much that further dischar-
ging would lead to a deep
discharge state and there-
fore damage the batteries.
In this case the only thing to
do is wait until the grid out-
age passes, the public elec-
trical grid once again starts
supplying electrical energy
and the Backup-Box auto-
matically switched to grid
operation.
The F1.B miniature circuit
breaker in the Backup-Box is
switched off.
Contact your installer to
check if the F1.B miniature
circuit breaker is switched
on.
The storage system is
switched off.
Switch on the storage sys-
tem.
Consumption is greater than
the specific nominal power
of the Backup-Box .
Switch off electrical con-
sumers or reduce their
power consumption.
Only connect electrical
consumers to phase L1 when
they have a power con-
sumption that does not ex-
ceed the nominal power of
the Backup-Box .
Only connect electrical
consumers to phase L1 when
they have a power con-
sumption that does not ex-
ceed the maximum power
of the Backup-Box when
switched on.
