2.5 Safety devices
The VARTA element energy storage system has multiple safety
devices. Including grid and system protection to VDE-AR-N 4105,
closed electrical operating area, overtemperature cutout and a door
contact switch. This switches off the system if an attempt is made
to open the storage cabinet before it has been de-energised.
Furthermore it is recommended to install a smoke detector in the
installation room of the VARTA element.

3 Function, scope of delivery and technical
parameters
3.1 Function
The VARTA element battery storage system is a storage system for
operation in a 3-phase building grid, which offers the option of
connecting a separate grid-connected photovoltaic system. This
must be a generating unit which supplies to surplus rather than to
full feed. There is also provision for storing renewable energy, for
example from small wind turbines or other CHP system energy
sources.
The VARTA element system is used to increase the share of
private consumption and the efficiency of a photovoltaic system. If
the photovoltaic system generates more electricity than
immediately needed, it can be stored temporarily in the energy
storage system. The electricity will be fed into the building grid, as
soon as the consumption rises again above the electricity
generated by the photovoltaic system.
The VARTA element system is integrated into the building grid as a
3-phase AC connection and operates independently of the
photovoltaic system. A current sensor controls the charge and
discharge processes of the energy storage system. It is mounted in
the fuse box, directly behind the consumption/feed-in meter, and
measures all incoming and outgoing currents.
If the current sensor measures outgoing currents in case of
available free charge capacity of the energy storage system, it will
be charged. During the process, the battery inverter inside the
VARTA element system converts AC to DC and charges the
battery modules. If the maximum charge capacity is reached, or the
solar electricity exceeds the maximum charging current, the surplus
solar electricity is fed into the public grid. If the photovoltaic system
Page 26
26
Subject to modification! Updated 10/2017
is not able to cover the current electricity demand inside the
building, the current sensor measures incoming currents. As a
result, the energy storage system gives output into the building
grid, in order to minimise the external electricity consumption and
the associated costs.
Before installing the VARTA element energy storage system, the
appropriate energy provider has to be asked, whether it is
necessary to register the system.

7 Transport and storage
7.1 Transport
Lithium-ion batteries are hazardous goods. The battery modules
are constructed and tested in a way, so they are allowed to be
transported up to a total weight of 333 kg by complying with the
conditions of ADR 1.1.3.6 (transport not subject to labelling, as long
as there are no other hazardous goods on or inside the vehicle).
The other requirements of GGVSEB (ordinance on the national and
international carriage of hazardous goods by road, rail, and inland
waterways) and ADR (Agreement on Dangerous Goods by Road)
also have to be fulfilled. Delivery is made in tested hazardous
goods packaging.
Lithium-ion batteries were successfully tested according to
UN 38.3 transport test (UN Manual of Tests and Criteria, Part III,
subsection 38.3) and have passed.
The storage cabinet is packaged separately from the battery
modules.

7.3 Packaging/transport control
Storage cabinet and battery module (individually packaged) are
delivered in separate and tested packaging units on pallets. The
disposal of the packaging will be taken over by the installation
engineer. Please examine the deliveries on completeness and
damages:
If damages are already visible at the packaging, please
note this down on the delivery documents and have the
driver confirm this by signature.
If the packaging is severely damaged, reject the deliveries.
In order to identify improper handling during transport, a
ShockWatch® sticker is attached to the outside of the cardboard
packaging of the storage cabinet. If the shock indicator is red, the
consignment has been exposed to strong vibrations.

8.6.3 Current sensor
If the energy storage system to be installed is to be cascaded with
further energy storage systems, the following step will not be
carried out. Instead, see instruction manual for cascading.
(Optional add-on package required)
In order to ensure the internal consumption optimisation, the
current sensor must capture all values of consumption and infeed.
Therefore, it is located directly behind the consumption and feed
meter. The current sensor is intended for top-hat rail mounting and
designed for a maximum current of 50 A per phase.

8.10 Initial commissioning
8.10.1 Checking the activation of the battery modules
If you do not perform initial commissioning directly after
the installation of the battery modules, the battery
modules have to be activated again. See Chapter 8.9.4
Installing and connecting battery modules.
8.10.2 Switching on
The VARTA element energy storage system is switched on as
follows:
Make sure that the network cable is connected.
Connect the fuse at the building grid.
Activate storage system using On/Off button. The button
will be locked in the lower position.

8.10.3 Password entry
The storage cabinet must be connected to the router of the home
network by means of the network cable.
Connect your PC/Notebook to the customer's network.
Enter the serial number of the energy storage system
behind http://varta in the address line of your browser.
e.g.: http://varta125023456
The serial number can be found on the rating plate on the
outside of the energy storage system.
The welcome page of the web interface will appear.
If the storage system cannot be accessed via the customer's
network, a connection can be established by means of the VARTA
network configurator (NCT). Enter your user name and password to
download this from:
https://www.varta-storage.com/de/nc/b2b.html.
Certain parameters may be changed only by trained and qualified
personnel, not by the operating company!
Enter the password into the field for installation engineer
access.

The storage system cannot be commissioned
unless the correct serial number(s) of the
battery modules are stated.
Remedy: LED ring flashes red
Error:
The current sensor check failed. Please switch the battery storage
system off and back on again.
If the LED ring continues to flash red after the restart (duration
approx. 3 minutes), check the connection to the current sensor
and the phase assignment.
If the LED ring continues to flash red, please contact VARTA
Storage GmbH.
The Settings page opens.
Click on the Basic settings tab.
Enter an individual name for the device. The maximum
length is 20 characters.
Enter the serial number(s) of the installed battery module
(expansion stage element 3/6)
or of the installed battery modules (expansion stage
element 6).
The sequence of the entry can be random.
Click on Apply.
Once the correct serial numbers have been entered, the
LED ring indicator changes from red to green.
If the LED continues to be red or to flash with a red light,
the following remedies have to be taken.

If IP address, DNS address and gateway are to be
set up statically, knowledge of the static address
assignment is required.
For this, it is required to read out the router's
network configuration, for example.
The address range 172.30.xxx.xxx and
172.31.xxx.xxx must not be used as a static or
dynamic IP for the storage system.
8.10.5 Portal connection
Select the Network tab from Settings.
By default, the storage device uses the customer's network
settings.
For this, the selection field next to Activate DHCP is checked as a
default setting.
If the connection is not made automatically, use the parameters in
the instructions for the network router. DNS and gateway address
are usually identical for commercially available DSL routers. These
addresses can differ for company networks. Moreover, ports 4500,
21 and 37 need to be enabled for the connection to the portal (does
not apply for all users).
See Chapter 9.4.2.
