2CHAPTER 2. SAFETY
2.4.1 What to do in case of fire / important
information for fire-fighters
Despite all the care that goes into electrical design it is
still possible for a fire to occur. Or a fire in the vicinity can
cause the storage system to catch fire. A fire can release
substances contained in the battery modules.
◮Observe the warning Risk of injury / burns through es-
caping electrolyte (7→ p. 8).
Consequently you should proceed as follows in the event of
a fire in the storage system or its surroundings:
◮Only firemen wearing proper protective clothing (includ-
ing gloves, masks, breathing apparatus) may enter the
room with the burning storage system.
◮A fire in the storage system can be extinguished by con-
ventional agents.
◮The use of water is advisable to cool the battery mod-
ules and thus prevent the thermal runaway of modules that
are still intact.
Information on battery modules:
•The battery modules have a rated voltage of 51.2
Vdc and are thus in the range of protective extra-low
voltage (below 60 Vdc).
•The battery modules contain no metallic lithium.
2.5 Warnings
This section deals with warnings that must always be ob-
served when working with the product.
DANGER
Danger to life through electric shock!
If the door to the cabinet is open, there is dan-
ger to life through electric shock if you touch
components inside the storage system.
◮Do not remove any plastic covers or sealed
parts.
◮By no means reach under covers.
DANGER
Danger to life through electric shock!
Observe the following if conducting any electri-
cal work on the storage system:
◮Disconnect the storage system.
◮Disconnect the back-up fuse.
◮Follow the five safety rules.
◮Have electrical jobs only carried out by qual-
ified persons.
WARNING
Danger to life through electric shock!
Even if the power supply from the public grid
is interrupted, parts of the electrical installation
can still be live. The storage system continues
to deliver electrical energy (using the optional
emergency power supply), so it has to be dis-
connected separately.
◮Cut out the electricity in the house.
◮Disconnect the storage system.
Attention
Damage to battery modules through exhaustive dis-
charge!
If not connected to the public grid the battery modules can
be damaged by exhaustive discharge.
◮Do not disconnect the storage system from the public
grid for an extended period.
KD-129 Sonnenbatterie eco Manual Version 1.04-1-EN 7 von 88

CHAPTER 2. SAFETY 2
WARNING
Risk of burns!
Very high shortcircuit currents are possible!
Observe the following when working with
battery modules:
When the fused connector is plugged in, a
battery module is active. So there is voltage
across the plus and minus contacts of the
battery module (rated voltage of battery
modules 51.2 Vdc). Unplugging the fused
connector deactivates the battery module.
Here there is no voltage across the plus and
minus contacts of the battery module. So
you can work on a battery module without
risk if all interconnected battery modules are
deactivated.
Working on DC circuit:
◮Take off metal jewellery of any kind that
could cause a shortcircuit.
◮Disconnect the storage system.
◮Disconnect the back-up fuse.
◮Remove the orange-coloured fused connector
on all battery modules.
WARNING
Risk of injury / burns through escaping elec-
trolyte
The battery modules fitted in the storage sys-
tem are guarded by a number of security de-
vices for safe operation. Despite diligent con-
struction battery cells inside the battery mod-
ules can still degrade or pyrolyze in the event
of mechanical damage, heat or a fault. The
possible effects are:
•High development of heat on the surface
of battery cells.
•Electrolyte can escape.
•Escaping electrolyte can ignite and pro-
duce an explosive flame.
•Smoke from burning battery modules
can irritate skin, eyes and throat.
Consequently proceed as follows:
◮Do not open battery modules.
◮Do not damage battery modules mechani-
cally (puncture, deform, take apart, etc).
◮Do not modify battery modules.
◮Keep battery modules away from water (ex-
cept to extinguish a fire in the storage system).
◮Do not allow battery modules to heat up and
only operate them in the allowed temperature
range (7→ 5.4.1 p. 18).
◮Do not shortcircuit battery modules / bring
them into contact with metal.
◮By no means continue to use a battery mod-
ule after a short.
◮Do not exhaustively discharge battery mod-
ules.
If contents escape:
◮Do not enter the room.
◮Avoid by all means contact with the escap-
ing electrolyte.
◮Contact your fire department.
◮Contact the following

[5] Feed-in
[6] Import
The storage system can directly influence the following en-
ergy flow:1
•Charging: Charging conducts energy into the bat-
tery.
•Discharging: During discharging part of the energy
intermediately stored in the battery is given off.
1Generation can also be influenced (throttled) to satisfy the constraint of a feed-in limit.
KD-129 Sonnenbatterie eco Manual Version 1.04-1-EN 9 von 88

CHAPTER 3. PRODUCT DESCRIPTION 3
•Consumption: Consumption can be increased by
connection of loads.
The purpose of controlling energy flow is to minimize en-
ergy import and optimize energy consumption.
3.4 Operating principle
The following is an example of operation of the storage
system together with a PV system. Instead of the latter it
is possible to connect other sources like a combined heat
and power unit.

[5] Battery
[6] Inverter of storage system
[7] Household supply
[8] Up/down meter
The DC current generated by a PV system [1] is converted
into AC current by an inverter [2]. The meters [3] and [4]
register momentary electric power in watts (W). Meter [3]
registers momentary power generation, meter [4] momen-
tary power consumption in a household [7]. If generation
is higher than consumption, excess electric power is saved
in the storage system. The battery [5] is charged. When it
is charging, the inverter of the storage system [6] converts
the fed AC current into DC current for the battery [5]. If
generation is less than consumption, electric power comes
from the storage system. The battery [5] is discharged, and
the inverter of the storage system [6] converts DC current
from the battery [5] into AC current. The up/down meter
[8] calculates the electric energy fed into the public grid
and that drawn from it in kilowatt hours (kWh).

3CHAPTER 3. PRODUCT DESCRIPTION
3.5 Feed-in power limitation
Depending on when a photovoltaic system was installed, it
may be subject to what is called feed-in power limitation.
Meaning that the power fed in from a photovoltaic system
is limited at the point where it ties to the grid.
Example
Rated power of PV system 10 kWp
Power limitation to 60%
Maximum feed-in power 6 kW
In this example the feed-in power must not exceed 6 kW.
The following illustration is an example of generation by a
PV system in the course of the day.

power
[1] First measure: charging of storage system.
[2] Second measure: connection of peak loads by wireless socket.
[3] Third measure: connection of loads linked to self-consumption
switch.
[4] Midday peak that may not be fed into grid.
To avoid throttling of generation – and thus loss of en-
ergy – the surplus is first saved in the storage system [1]
and consumption is increased by connecting loads [2] and
[3]. Generation is only throttled if these measures do not
produce the desired limitation.
Feed-in power limitation is activated by your electrician
when installing the system according to Settings – Genera-
tor – PV – General (7→ 10.3.7 p. 59).
In what follows you can read details of the steps to imple-
ment feed-in power limitation. Follow the steps one after
the other. Only move on to the next step if a particular
step does not lead to the wanted reduction.
1. Charging of battery
Surplus energy is fed into the battery, which there-
fore needs sufficient capacity. So on sunny days it
is often advisable to reduce charging power in the
morning hours to leave enough battery capacity for
midday. For this reason there is intelligent control of
charging pattern (7→ 3.6 12).
2. Connection of loads linked to wireless sockets (op-
tional). ). These loads must be marked as peak loads
through the portal (7→ 11.2.4 p. 64). The loads are
activated as soon as the feed-in limit is exceeded.
Loads are deactivated again if the limit drops after 3
minutes.
3. Activation of self-consumption switch (7→ 10.3.9
p. 60)so that loads possibly on the hardwired switch-
ing output are connected.
4. Reduction of PV power over integrated switching
contact on inverter. This limits the photovoltaic in-
verter to set power output. The requisite is support
of the inverter for power reduction over a switching
contact or an external solution (e.g. a solar data log-
ger). Configuration and connection are by a qualified
electrician.
5. Cutout of photovoltaic system if all the steps have
no effect (exceeding of maximum feed-in power de-
spite activation of all points on average 10 minutes).
The photovoltaic system remains separated from the
grid for a period of at least 5 minutes (configured by
electrician) and is afterwards automatically released.

CHAPTER 3. PRODUCT DESCRIPTION 3
3.6 Intelligent charge management
Charge management means intelligent control of the charg-
ing pattern of the storage system. The purposes of this
intelligent control are as follows:
•Storage of the midday peak in the storage system
(sufficient storage capacity must be available).
•Full charging of the storage system by the evening
(to provide sufficient energy for the nighttime).
Intelligent charge management only works in storage sys-
tems operated together with PV systems, and in which
feed-in power limitation is activated.
Operating principle of intelligent charge man-
agement
The storage system is connected over the Internet to a
server. This produces a generation and consumption fore-
cast for the particular day. The generation forecast is based
on the following data:
•Forecast weather data
•Rated power of PV system
•Orientation of PV system
The consumption forecast is calculated from consumption
in recent weeks. The following illustration is an example
of such a consumption and generation forecast.

Here, for example, average consumption of 0.5 kW is ex-
pected between 10:00 and 11:00 h plus generation of ap-
prox. 9 kW. Subtracting consumption from generation pro-
duces the forecast surplus (here 8.5 kW). In the following
illustration the consumption bars are shifted to the top of
the generation bars.

Figure 3.5: Forecast surplus

In this example, feeding in the entire surplus at midday
would violate the feed-in power limitation (at 6 kW). So
it is best if as much energy surplus as possible above the
feed-in limit is used to charge the battery.
Without intelligent charge management the storage system
would immediately save the surplus (through to maximum
charging power – see Technical data) in the battery.

In the example looked at here, this pattern would mean
that the storage system was fully charged before midday.
So the subsequent surplus above the feed-in power limita-
tion could no longer be stored in the battery. To satisfy the
feed-in power limitation (7→ 3.5 p. 11) the power of the
PV system would have to be reduced. That would mean
both a financial and an energy loss.

[green] Charging of storage system
In the example, charging of the storage system is avoided
in the morning hours. At midday the storage system is
charged just enough to satisfy the feed-in power limitation.
Adaptation of intelligent charge manage-
ment
After starting up, intelligent charge management has to
match to local conditions. The generation forecast de-
pends for example on the weather forecast, on orientation
and roof angle, shadowing, etc of the PV system. A con-
sumption forecast depends on your energy use and your
electric loads or household appliances. Enabling intelligent
charge management to adapt to this complexity of factors
calls for consumption and generation statistics. None of
the data needed are present after installation of the stor-
age system, so they need to be collected. For this reason
intelligent charge management takes approx. 7 days to cal-
ibrate. During this time there may be unwanted charging.
After the 7 days intelligent charge management will have
adapted to your personal generation and consumption pro-
file.
Limits of intelligent charge management
The effectiveness of intelligent charge management de-
pends on how accurate generation and consumption fore-
casts are.
•The wrong weather forecast will mean a poor gener-
ation forecast.
•A consumption forecast depends on figures of recent
weeks. So heavily fluctuating consumption has a neg-
ative effect on the quality of the forecast. The more
constant your consumer pattern, the preciser is the
consumption forecast.

CHAPTER 4. STORAGE AND TRANSPORT 4
4 Storage and transport
4.1 Storage
Storage is the condition where the energy storage system
is not connected to the public grid and there can be no
automatic charging of battery modules.
4.1.1 Ambient conditions for storage
◮Ensure the following ambient conditions for storage of
the energy storage system and battery modules:
•Ambient temperature must be between
0 and 40 ➦ C.
•Otherwise maintain the same ambient conditions as
at the point of operation (7→ 5.4.1 p. 18).
4.1.2 Storing battery modules
Attention
Damage / destruction of battery modules through ex-
haustive discharge!
Battery modules discharge to a minimum degree by them-
selves during storage. But exhaustive discharge can damage
or destroy them. So only store battery modules for a lim-
ited period.
◮When put into storage battery modules must have 85 %
charge (as delivered).
◮Do not store battery modules for longer than 6 months.
◮At the latest after 6 months fit battery modules into the
storage system and start it up.
◮During storage the orange-coloured fused connector must
not be plugged into a battery module. 1
4.2 Transport
4.2.1 Ambient conditions for transport
◮Ensure the following ambient conditions for transport of
the energy storage system and battery modules:
•Ambient temperature must be between
-15 and 40 ➦ C.
•Otherwise, if possible, maintain the same ambient
conditions as at the point of operation
(7→ 5.4.1 p. 18).
4.2.2 Transporting battery modules
Lithium-ion batteries rank as hazardous goods, so take the
following precautions when transporting battery modules:
◮Observe general regulations of the transport carrier and
all legal regulations.
◮Seek advice from an external hazardous goods consul-
tant.

4CHAPTER 4. STORAGE AND TRANSPORT
4.2.3 Inspecting for transport damage
The haulier can be held responsible for transport damage
if it is possible to prove that the damage was caused dur-
ing actual transport. Therefore it is important to strictly
follow these instructions.
Transport damage is categorized as open or hidden. Open
damage is when damage to the goods in transit or their
packing is visible externally. Hidden damage is when the
packing looks undamaged but the contents are then found
to be damaged.
A complaint of open transport damage must be lodged
with the haulier immediately. For hidden transport dam-
age a complaint must be lodged as follows:
Haulier Complaint at latest
Deutsche Post / DHL / parcel services 24 hours
Forwarder 7 days
1Checking freight documents
◮Check the address of the recipient and number of pieces
in the presence of the haulier.
2Checking freight for open damage
◮Check the packing and transported goods for external
damage in the presence of the haulier.
If damage is determined:
◮Check the freight also for hidden damage in the presence
of the haulier.
◮Check the shockwatch attached to the packing of the
main cabinet in the presence of the haulier.
Figure 4.1: Shockwatch
If blue powder appears in the arrow of the shockwatch, the
storage system was not transported properly.
◮In this case you should refuse to accept the freight.
3Checking freight for hidden damage
Conduct this also in the presence of the haulier.
◮Unpack the delivery and inspect it for hidden damage
(not immediately visible).
◮Do not continue to unpack if you determine transport
damage.
◮Immediately photograph the damage.
◮Refuse to accept the freight if it is heavily damaged.
4Documenting damage
◮Note the damage you find as ” Conditional acceptance“
on the bill of consignment and have this confirmed by the
signature of the haulier. The registration number of the
delivering vehicle on the bill of consignment should also be
documented.
5Complaining of damage
◮Complain of damage immediately to the responsible
haulier and the manufacturer.
◮Send the bill of consignment / waybill with confirma-
tion of damage by the haulier plus photographic evidence
by e-mail to the manufacturer.
It is not possible to settle a claim for damages
without submission of the above papers within
deadlines for complaints.
Inspecting battery modules
CAUTION
Risk of injury by using damaged battery
modules!
Using these can cause the release of substances
injurious to health.
◮Unpack battery modules immediately after
transport and check them for transport dam-
age.
If deformation, damaged casing, leaking con-
tents, etc is determined:
◮Do not use the battery modules under any
circumstances.
◮Contact the service point.
