2.2 Overview of function and installation
These sonnenBatterie pro2.0 instructions are a supplement to the applicable
product documentation for the sonnenBatterie eco8.0. The product docu-
mentation, above all the installation instructions, must always be observed.
• The sonnenBatterie pro2.0 consists of three individual eco8.0 storage systems.
• During installation one storage system is designated as the master and the other two as
slave1 and slave2. The master storage system controls the other storage systems after
installation is complete.
• Connections such as the Modbus line or signal line are made on the master storage sys-
tem.
• The storage systems are connected to each other by Ethernet cable. An external switch
is installed for this purpose, to which all three storage systems are connected. The
switch is connected to the home network router.
• If a router with a sufficient number of free slots is available, the external switch can be
omitted.

3.1 Selecting the installation location
The heavy floor load applied by the storage system must be taken into account
when selecting the installation location. The specified weight for the entire sys-
tem can be found in the section Technical data [P.6]. Applicable building codes
must be observed in each case!
3.2 Observing minimum distances

Illustration3: Minimum distances to neighbouring objects
Observe the specified minimum distances to neighbouring system parts or objects.
The minimum distances ensure that:
• there is sufficient heat dissipation,
• the storage system doors can be opened easily and
• there is sufficient space for installation and maintenance work.
3.3 Installing the storage systems
Install the storage systems in a suitable location as described in the relevant installation
instructions.

4 Electrical installation
DANGER Electrical work on the storage system and electrical distributor
Danger to life due to electrocution!
Switch off the storage system to electrically isolate it.
Disconnect the relevant electrical circuits.
Secure against anyone switching on the device again.
Wait five minutes so the capacitors can discharge.
Check that the device is disconnected from the power supply.
Only authorised electricians are permitted to carry out electrical work.
NOTICE Observe maximum line lengths
None of the lines connected to the storage system (mains line, ethernet
line, other data lines) are allowed to exceed a maximum length of 30m.
4.1 General information about installation
Always observe the specifications in the installation instructions for the eco8.0 stor-
age system.
Important note:
• The conditions described in the installation instructions for the relevant storage system
apply to the installation of the residual current device (RCD) marked in figure 'Circuit
diagram overview - electrical connection of the pro 2.0 [P.11]’. If an RCD of the re-
quired type is already installed, it is not necessary to install an additional RCD.
• In the case of an existing installation of three eco8.0 storage systems connected in par-
allel, the installation of the power meters must be changed.
4.2 Selecting the measurement concept
• The standard measurement concept (also referred to as the CP measurement concept
or setup 1) is recommended for power measurement of a sonnenBatterie pro 2.0. This
corresponds to the structure of the installation described in the following section Wiring
the components [P.11].
• The GP measurement concept (also referred to as setup 4) should only be used if the
standard measurement concept can’t be implemented or if the individual components
for the power measurement are already installed as the GP concept and elaborate con-
version is to be avoided. Please note that the GP measurement concept can lead to a
lower efficiency of the storage system.
• Measurement concept GP (setup 4) must not be used if several pro 2.0 storage systems
which are connected to the same production unit (e.g. pv system), are connected in
parallel.

4.4 Electrical connection
4.4.1 Connecting the mains line
Observe the following points:
• The mains connection must be protected with a typeB miniature circuit breaker, rated
current 13A or 16A.
• The cable cross-section from the miniature circuit breaker to the electrical consumer
must be adapted to suit the larger loads if necessary.
Connect the mains line as described in the installation instructions for the eco8.0 stor-
age system (section ‘Connecting the mains line’).
4.4.2 Connecting the Ethernet lines
The connection to the customer router is established via a switch. If the customer router
has a sufficient number of free slots, the three storage systems can be connected directly
to the router. A switch is not necessary in this case.
Connect the Ethernet lines as shown in figure System components [P.8]. The Ethernet
cables, the switch and the router are not included in the scope of delivery.
The required output type can be found in section ‘Connecting the Ethernet cable’ in
the storage system installation instructions.
4.4.3 Connecting the Modbus line
Connect the Modbus cable as shown in figure System components [P.8].
4.4.4 Connecting the signal line
Connect the signal cable to the master as described in the storage system installation
instructions.

6 Display on the internet portal
• The internet portal presents current information and data for the storage system.
The description of the individual operating steps, the displays and diagrams and the re-
gistration process can be found in the operating instructions for the relevant storage
system.
• To view the data for the sonnenBatterie pro2.0, the system must be registered with the
serial number of the master storage system. The data for the entire pro2.0 system, such
as the PV production, consumption and discharge, is displayed on the internet portal for
the master.
• In theory it is also possible to log in using the serial number of one of the slaves, but
please note that in this case not all data will be displayed after the pro2.0 is configured,
not even for the individual eco8.0 storage system.
