General
The installation must only be carried out by competent
personnel.
The enclosed materials are those required for the installa-
tions described (see page 12),. In special cases, these may
need to be supplemented. If in doubt, contact your supplier.
Information on the applicable standards and regulations
must be obtained prior to installation and commissioning.
The electrical installation, as well as the notification to the
network operator, must be carried out by a qualified electri-
cian. Please note that commissioning the installation before
the network operator has given its approval is not permitted.
NOTE
Installation of a solar panel is an extensive inter-
vention on an existing roof. The roof covering,
particularly on converted and inhabited loft spaces
or where the roof's minimum angle is undersized
(relative to the covering), may require further
measures against moisture because of wind pres-
sure and drifting snow, this must be evaluated by
the installer on a case to case basis. The roof
design must be able to handle the wind and snow
loading that can occur in the region.
STATIC LOAD
The installation is only permitted to be performed on roof
surfaces or support structures with sufficient carrying ca-
pacity and strength. If necessary, the static load capacity
of the roof and roof structure must be investigated before
the solar panels are installed. Great importance should be
placed on the condition of wooden roof structures and the
possibilities for screwing the mounting devices for the solar
panels to the structure. The roof structure must be rein-
forced if necessary. Inspection of the whole solar panel in-
stallation in accordance with DIN 1055 part 4 and 5, or in
accordance with country-specific regulations, is required,
in particular in areas that experience snowfall and strong
winds. The characteristics of the installation’s location
(prevailing wind direction, whirlwinds, etc.) must also be in-
cluded in the calculation/estimate if these could involve in-
creased loads. The solar panels must be installed so that
snowdrifts resulting from snow guards or due to special
conditions in the installation location cannot occur in the
vicinity of the solar panels.
The distance from the outer edges of the roof must be at
least 0.35 m at the sides of roofs and 0.2 m at ridges and
eaves, in order to reduce the risk of the wind ripping the
solar panels off.
The installation system according to DIN 1055 part 5 for
snow zone II is intended for use up to 400 m above sea level.
If the installation is made on a tiled roof, it is recommended
that the snow is cleared if it reaches a depth of more than
30 cm on the solar panels (NOTE! If the snow has melted,
been packed down and then more snow has fallen and so
the density has increased, the snow may need to be cleared
- even though it is not 30 cm deep.)
If there is a risk that the snow will slide down onto the panels
and in particular behind the rear of raised panels, snow
guards must be installed to prevent this.
Also ensure that the material under roofs with roof tiles is
sufficiently stable to support the roof mounting points.
Otherwise the roof must be reinforced. The installer must
evaluate this and make a decision. If in doubt, a structural
engineer needs to be consulted. We also recommend that
the roof tiles should be ground down so there are no point
loads between the roof and the roof brackets. The minimum
distance between roof tiles at overlap points and the under-
side of the brackets is 3 mm, in order to allow for any
movements in the mounting system due to the loads that
can arise.
SAFETY INSTRUCTIONS
•Safety regulations for working on roofs and similar struc-
tures must be followed.
•Protection against falling parts must be installed. This is
particularly important in locations where people pass be-
low the roof/building.
•Personal safety equipment and/or scaffolding must be
used when working on roofs, according to applicable reg-
ulations.
•Suitable measures must be taken during installation to
ensure that the solar panel does not come loose and fall.
•Observe the safety distance to live conductors.

Installation and positioning
Using the map and the diagram, it is possible to estimate
the annual value of the insolation on the surface where the
solar panels are placed.
100% is the insolation at a horizontal surface. The angle of
inclined surfaces is 45°.
The diagram shows insolation as a percentage of global ra-
diation in relation to surfaces at various orientations and
angles.
The map shows lines with the same global radiant flux, i.e.
the insolation measured at horizontal surfaces.

1. Calculate the annual solar radiation using the map. The
specific solar radiation for the installation is obtained
as a percentage, based on the location of the solar
panel according to the diagram.
2. Multiply the results by the installation’s peak output
(e.g. 4 / 8 / 12 / 16 / 20 kW).
3. Multiply the result 2 by a constant 0.9 to calculate the
energy production in kWh/year (with a reservation for
shade, dirt and snow coverage).
Example: Prague, 8 kW, 45°, installation south (112 %).
1120 x (112/100) x 8 x 0.9 = 9032 kWh/year

Functions
MYUPLINK / NIBE UPLINK
With myUplink and the Internet, you can obtain a quick
overview and the current status of the solar panel system
on your property. You receive easy-to-grasp and good
supporting data, where you can see the current power and
the history. In the event of any malfunction, you also receive
an alarm directly in the app, which allows you to take prompt
countermeasures. myUplink requires the accessory EME 20,
which is enclosed with the inverter.
WIFI COMMUNICATION MODULE
CMO 11 / CMO 22
With this accessory, you can connect the inverter to its portal
without myUplink.
CMO 11/22 communicates with your home network via wifi.
See separate manual for more information and installation.
CMO 11 is used for inverter PVI 10 and CMO 22 is used for
PVI 20.
11Chapter 3 | InstallationNIBE PV Solar cell package

Installing solar panels in several
groups
Examples of possible combinations per ten panels:
To reduce the risk of damage to the electric cables between
the groups of solar panels, these can be run underneath the
roof tiles or ceiling. To prevent moisture penetrating under
the roof tiles or through the damp barrier at the holes for
the electrical cables, diffusion sealed lead-ins must be fitted.
Horizontal installation
The rails are installed vertically in the case of horizontal
mounting. Remember that extra roof brackets and clamps
are required.
Horizontal installation on a tiled roof also requires a retrofit
kit PRM 61-20.
Specially adapted roof brackets for tiled roofs, sheet metal
roofs, felt roofs or seamed sheet metal roofs. The type of
roof bracket to be used must be specified when ordering. If
the panels are installed in a different formation, additional
mounting materials may be required.
Caution
Additional connectors and mounting materials may
be required to install solar panels in different
groupings.
ADDITIONAL PANELS
Each package can be expanded with additional panels (PVK
40-1).
This means that you have extremely good flexibility, allowing
attractive roof installation.
Caution
Check that the inverter can cope with the total
power with additional panels.
Example
8 kW package installed on roof that is expanded by e.g. four
solar panels (9.6 kW)
8 kW package installed on roof where it was decided not to
install e.g. two panels (7.2 kW).

Number of solar panels per string and per package
The table shows how many panels you can have per string, as well as how many panels are standard and how many the
inverter can cope with. The inverter has dual trackers, allowing the installation of different numbers of panels per string.
If the number of panels is not sufficient to achieve the minimum number for two strings, you have to install all the panels
in one string.

NOTE
Electrical installation and service must be carried
out under the supervision of a qualified electrician,
and in accordance with applicable electrical safety
regulations.
Factory-fitted junction boxes prepared with cables for pos-
itive and negative connections can be found on the reverse
of the solar panels. The cables are fitted with quick-release
connectors.
The electrical cables between the panels and the inverter
must be double insulated and UV/weather-resistant
photovoltaic cables, 4 mm² up to 100 m length (not supplied).
The inverter is connected and fused to the fuse panel as if
it was a load with the same output. The inverter includes a
factory-fitted 300 mA residual current device. If the inverter
is to be connected to an external residual current device,
this must be 300 mA or larger and of type A.
NOTE
The inverter is powered by the voltage from the
solar panels. At night and in poor light, the inverter
may therefore be switched off.
LIGHTNING PROTECTION
There are occasions when lightning protection can affect
how the installation is installed. See the applicable laws and
regulations.
NOTE
In order to minimise the risk of induced voltages
in the event of lightning, the return cable must be
laid together with connection cables for the panels
connected in series.
