Function
The energy storage system increases the use of home-generated electricity. Whereas the
standard energy output of photovoltaic systems is usually only around 20%, this value can be
increased to over 70%. The annual electricity bill can therefore be reduced as long as the elec-
tricity consumption does not increase. These values strongly depend on the design of the pho-
tovoltaic system, energy storage system and consumer behaviour and may vary significantly in
individual cases.
If a feed-in tariff is paid, for example in accordance with the Renewable Energy Sources Act (Er-
neuerbare-Energien-Gesetz - EEG), the annual payback decreases due to the reduced amount
of electricity fed into the grid.
Correct use
–The energy storage system is exclusively designed for operation with the Hager energy
management controller flow. Home-generated electricity produced by photovoltaic sys-
tems is consumed, stored or fed into the grid.
–Communication with the energy management controller XEM461 in the local network.
–The energy storage system is connected to the home network in the cut.
–The energy storage system is suitable for indoor use only.
–The instructions that come with the device are part of the product and must be kept safe
for use at any time.

Energy storage system assembly
Selecting a suitable assembly location with permissible environmental conditions
CAUTION!
The energy storage system must be permanently wired into the existing
building installation and meet the applicable national installation regulations
and legal provisions.
The manufacturer does not assume any liability in the event of non-compliance
with the assembly location requirements and permissible environmental
conditions.
ç

requirements must be complied with:
–No direct sunlight
–Room temperature between 5 °C and 35 °C
–No area subject to explosion hazards
–No room subject to flooding
–Dry room
–No corrosive gases
–No environment containing ammonia
–No saline humidity
–No heaters in the immediate vicinity of the assembly location
–It is recommended to choose a well-ventilated assembly location to prevent heat accumu-
lation
–Minimum room volume (generally designed for non-climatised interior room)
- With active room ventilation: 10 m³
- Without active room ventilation: 50 m³
–Minimum space below, above and in front of the energy storage system in accordance
with specifications:
- below the energy storage system: min. 20 cm or base assembly
- above the energy storage system: min. 20 cm
- in front of the energy storage system: min. 80 cm
–The maximum assembly height is 2,000 m above sea level.
Installations at greater altitudes must be requested from Hager and are possible if taking

–If assembling the system in the living space, please note that the device may emit noise
during operation (fan noises, etc.) that may become a nuisance.
–During installation, ensure that the energy storage system will not be mechanically im-
paired during installation or daily operation (e.g. by doors that hit against the energy stor-
age system when opening). Further measures for the mechanical protection of the energy
storage system may have to be implemented.
–Emergency exits must be kept clear at all times
–Applicable fire protection regulations must be complied with
–An ABC fire extinguisher or carbondioxyde extinguisher should be available.
It is recommended to design the operating room in accordance with F30 (fire-retardant). and

Assembly on the wall
CAUTION!
2 fitters are required for assembling the energy storage system on the wall due
to its great weight.
ç
The system must be assembled on a smooth, solid and non-flammable wall. The load-bearing
capacity of the wall must be designed to hold the weight of the energy storage system (Table 5).
Energy storage system XEM1000 / XEMV1000 / XEM2000 / XEMV2000
Weight approx. 240 kg
Table 5: Weight of energy storage system
The weight can be used to determine a suitable fixing system by fixing system manufacturers.
The manufacturers provide helpful tools, such as an anchor finder (Table 6), for selecting the
correct anchors.
A minimum of 4 or more fixings (e.g. screw-anchor combinations or anchors) with a maximum
diameter of 8 mm (max. drillhole diameter 10 mm) must be used.
For example, an installation with four UX 10 x 60 anchors in a concrete wall with a minimum
thickness of 25 cm would result in a load-bearing capacity of 400 kg, which would be sufficient
to hold the system.
When assembling the energy storage system on a wooden wall, it must be mounted on
non-flammable material! Construction panels made from calcium silicate are suitable for this
purpose, for instance.
Aerated concrete walls are generally unsuitable for attaching the energy storage system, for
example. In this case, the energy storage system must be installed on a base, as described in
the section about base assembly on page 18.
