fications may be made to the device.
Intended use
VARTA pulse neo with its components is built according to the state of the art and the product-
specific standards and is to be used for the storage of electricity from photovoltaic systems. Other
uses must be coordinated with the manufacturer and the local energy supplier. The energy storage
system may be operated only while suspended on the wall.
Erroneous use
WARNING
Possible danger to life due to erroneous use!
Possible danger to life.
In the interior of the device there are parts with dangerous voltages. Con-
tact with these can lead to death.
Any use that goes beyond the intended use or other use of the energy
storage system or individual parts can lead to life-threatening situations.
Prohibited use
Do not use VARTA pulse neo:
! for mobile use on land, water, or in the air.
! for use on medical equipment.
! e.g. on the floor or table, lying or standing.

11
Electrical specialist requirements
Activities on the VARTA pulse neo system (e.g. installation and maintenance work) may be
performed by qualified electrical specialists certified by VARTA Storage only!
Here, specialists refers to persons who, among other things, possess the knowledge of relevant
terms and skills. Are able to evaluate the following works and recognise possible dangers due to
their technical training, knowledge and experience as well as knowledge of the relevant provisions:
! Assembly of electrical equipment.
! Assembly and connection of data lines.
! Assembly and connection of power supply lines.
General danger sources
If the following directions on handling the device are not complied with, this can lead to personal
damage and material damage to the device for which VARTA Storage GmbH assumes no liability.
Danger due to electrical voltage
DANGER
Contact with electrical voltage.
Danger to life due to electric shock.
Always keep the energy store closed.
Look out for damage to the electrical equipment.
Have defects eliminated immediately.
Only the electrical specialist is allowed to open the energy store.
The energy store may be opened only while switched off.
Comply with a waiting time of at least 3 minutes.

12
Danger due to water
WARNING
Entry of water into electrical installations.
Possible danger to life and material damage.
Do not use water to clean the energy store.
Do not deposit containers with liquids (such as drinks cups) on electri-
cal installations.
The relative humidity in the room must not exceed 80%.
Danger due to oxidising and corrosive substances
WARNING
Storage and use of oxidising and/or corrosive substances.
Increases the fire risk and the risk of electric shocks.
Store the above-named substances only in the places intended for
them.
Do not clean the system with acid-, lye- or solvent-containing means.
Danger due to heat
ATTENTION
Insufficient ventilation of the system
Overheating of the system possible.
Keep vents clear.
Ensure sufficient ventilation.
ATTENTION
Heat entry due to direct solar radiation or devices that emit heat
Overheating of and damage to the system possible.
Protect system from direct solar radiation.
Do not use a fan heater or a similar device near the system.

13
Misconduct
ATTENTION
Energy store switched off
Possible damage to the batter module due to deep discharge.
The energy storage system may be switched off only temporarily for
maintenance purposes.
ATTENTION
Objects on the system
Risk of injury due to falling objects and the system can be damaged.
Do not deposit objects on the energy store.
ATTENTION
Access blocked
System cannot be switched off in the event of damage.
Access to the energy store must be ensured at all times.
Safety equipment
WARNING
Defective safety equipment
Possible danger to life.
Safety equipment must not be damaged, modified, removed or decom-
missioned.
The flawless functioning of the safety equipment must be checked fol-
lowing the end of the installation and commissioning by qualified elec-
trical specialists certified by VARTA Storage.
The VARTA pulse neo energy storage system has several pieces of safety equipment. These include
grid and system protection e.g. according to VDE-AR-N 4105, closed electrical operating area, over-
temperature switch-off and a mechanical switch-off mechanism. The latter switches the device off
when an attempt is made to open the housing without previously disconnecting the energy store
from the mains.
A smoke detector must be installed in the setup room of the VARTA pulse neo.

14
Function, scope of delivery and technical parameters
The energy storage system VARTA pulse neo is intended for operation on the 230 V house network
and offers the option of connecting a separate grid-connected photovoltaic system. The latter must
be a generation system that feeds in not at full infeed, but after excess.
The energy storage system serves to increase the percentage of self-consumption and the economic
efficiency of a photovoltaic system. If the photovoltaic system produces more electricity than is im-
mediately consumed, it can be stored intermediately in the energy storage system. The electricity is
fed into the house network again from the store as soon as the consumption is bigger again than the
electricity quantity generated by the photovoltaic system. The energy storage system is integrated
into the house network on the alternating current side and works independently of the photovoltaic
system. A current sensor controls the charging and discharging processes of the energy storage sys-
tem. It is mounted in the fuse box directly after the consumption/feed-in meter and measures all
incoming and outgoing currents.
If the current sensor measures outgoing currents while there is available free charging capacity of
the energy storage system, the latter is charged. In the process, the batter converter in the energy
storage system converts the alternating current into direct current and charges the battery module.
If the maximum charging capacity is reached or if the solar-produced electricity exceeds the maxi-
mum charging current, the excess solar power is fed into the public network. If the photovoltaic sys-
tem cannot cover the current electricity requirements in the house, the current sensor measures
incoming currents. Thereupon, the energy storage system issues power into the house network in
order to minimise the external volume of purchased electricity and the associated costs.
Note:
Before installation of the VARTA energy storage system, it must be clarified with the respective
energy supplier/electricity grid operator whether it is necessary to register the system.
Derating
Derating means a temporary curtailment of the maximum performance of the battery converter in
order to prevent components from being heated excessively. VARTA energy storage systems are de-
signed in such a way that when the operating and environmental conditions are complied with the
permitted operating temperature is not exceeded and a derating is not necessary. To avoid a temper-
ature derating of the energy store, you should ensure that the energy store can issue the heat to the
ambient air.
Frequent temperature-induced derating can have the following causes:
! The system cannot issue enough heat to the ambient air because the air filter is soiled or the
ventilator has failed.
! The installation site of the energy store does not offer the requisite climatic conditions.
! Atypical operation that deviates heavily from the photovoltaic cycle.
