TECHNICAL DATA
The switching device distributes the power of several
photovoltaic modules to different electrical loads.
The product primarily serves as an energy
management system. The energy generated by the
photovoltaic modules can be distributed efficiently
and with different priorities to the connected loads by
the switching device.
Up to four photovoltaic modules can be connected to
the switching device. For this purpose, the
photovoltaic inputs - PV1 to PV4 - are used. The energy
generated by the photovoltaic modules is distributed
to up to three electrical consumers. These are
connected to the load outputs - Output 1 to Output 3
- (see graphic)
Prioritization:
The switching device prioritizes the connected loads
differently. The output - Output 1 - has first priority.
This is followed by - Output 2 - and then - Output 3 -,
On - Output 1 - connected loads are prioritized and
supplied with energy. If the photovoltaic modules
generate more power than the consumers connected
under - Output 1 - can use, individual/ entire
photovoltaic modules are switched to the second
load output - Output 2 -. If surplus energy is also
available, the - Output 3 - output is also supplied with
energy. If a consumer does not consume power
(anymore) (eg fothermo photovoltaic boiler has
reached the maximum temperature), the existing
power (photovoltaic modules) is switched to the other
connected consumers with a lower priority if possible.
If more power from the photovoltaic modules is
available than the maximum power specified by the
outputs (600W or 400W), individual photovoltaic
modules are temporarily switched off.

EN
APPLICATION
IMPORTANT: Make sure that the connected
consumers are compatible with the permissible
system specifications of the photovoltaic modules.
fothermo Boiler + Micro PV Inverter*
The switching device allows the use of excess energy,
which can no longer be stored in the fothermo
photovoltaic boiler as heat.
* For the connection of an inverter, the use of Mirco PV
inverters" or "balcony power plant inverters" is
provided. these are limited to a power of 400W per
photovoltaic module input. It should be noted that
the inverter has a separate input for each photovoltaic
module. If several photovoltaic modules can be
connected to one input of the inverter, the use in
combination with the switching device is not possible.
INSTALLATION
1. Assembly: Install the switching device in a dry
room. It is mounted on a fixed wall using the four
screws supplied. During installation, sufficient
distance to neighbouring walls and enough distance
under the device for photovoltaic connections must
be provided.
2. Connection of photovoltaic modules:
IMPORTANT! Operation is performed with direct
current.
IMPORTANT! Only photovoltaic modules of the same
type may be individually switched the inputs of the
switching device.
IMPORTANT! A series or parallel connection of the
photovoltaic modules at one input leads to a defect of
the device.
IMPORTANT! The connected photovoltaic modules
must comply with the electrical limitations of the
connected loads.
IMPORTANT! The installation of PV modules may only
be carried out by a competent person and must
exclude any risk to third parties. When installing the
photovoltaic modules, the local rules and laws must
be observed.
IMPORTANT! Only photovoltaic modules with a
maximum open circuit voltage of 50 V specified in the
data sheet may be connected. Up to four photovoltaic
modules with 450Wp each may be connected to the
designated connections of the system.
The photovoltaic modules and the loads are
connected via the screw terminals of the switching
device. The connections for the photovoltaic modules
on the switching device are marked in green. Make
sure that the photovoltaic modules are connected
with the correct polarity.
Start by connecting the photovoltaic modules to the
left of the terminal strip at the first terminal (PV1+) for
the positive (+) and (PV1-) for the negative terminal (-)
of a photovoltaic module. Mount further modules
from left to right in ascending order of numbers
according to the principle described above.
Check that the display of the switching device lights
up after connecting the first photovoltaic module.
After connecting the first photovoltaic module, a
timer of 5:00 minutes begins to count. You should
connect all photovoltaic modules within this given
time. This ensures that the switching device detects
all photovoltaic modules and ensures perfect
operation.
If you could not connect all photovoltaic modules to
the switching device within 5:00 minutes, you should
disconnect all photovoltaic modules from the
switching device and restart the timer.
The device is completely disconnected from the
power supply system when all supply plugs/
photovoltaic modules are disconnected.
3. Connection of electrical consumers: The loads are
mounted on the blue terminals. At the first load
output - output 1 - the fothermo photovoltaic boiler is
connected. For this purpose, the terminal with the
designation Out + is connected to the connector for
the positive photovoltaic module voltage (+).

EN
The terminal block Out - is connected to the negative
terminal (-) of the device.
The Mirco PV inverter is connected to the load outputs
- Output 1 - and/ or - Output 2. The respective terminal
Out + is connected to the connector for the positive
photovoltaic voltage (+). The terminal Out - is
connected to the negative connector (-) of the Micro
PV inverter.
You can use the supplied 6x MC4 contact plugs to
connect the electrical loads. Take the MC4 plugs with
the red cables for the connection of the positive +
photovoltaic voltage and the MC4 plugs with the blue
cables for the negative - photovoltaic voltage.
OPERATION
Operation:
When the device is commissioned, the number of
connected photovoltaic modules is determined after
the 5:00 minute timer has expired. After proper
installation, the switching device automatically
switches the photovoltaic modules to the connected
loads. This is done depending on the incoming
photovoltaic power. No operation by the user is
possible. The display is used to read the current
system status during operation. The display is
structured as follows:
If several outputs are active, they are displayed
sequentially. If only one output is active, the display is
not switched.
If the display - Check Output 1 - is shown on the
display, the switching device waits for the load to
automatically switch to Output 1. If no power is
consumed by the connected load, the switching
device switches the photovoltaic modules to the
second output. Switching is fully automatic and can
take up to 5 minutes per output.
If an output takes up little power, the modules
connected there are switched to another output after
a short time. This ensures that the prioritization (see
section above, Prioritization) of the outputs is
maintained and the best possible use of the
photovoltaic modules is ensured. This scenario is
indicated by the following image about the device,
where an arrow indicates in which direction the
module, or modules, will be transferred after the
output is switched off. In the example shown, the
module connected to output 2 is switched to the left,
i.e. to the first output.
MAINTENANCE AND
REPAIR
To clean the switching device, remove all electrical
connections first. The outer shell and the plastic parts
of the device can only be cleaned with a slightly damp
cotton cloth, without aggressive and/ or abrasive
cleaning agents. The device can only be put back into
operation after complete removal of moisture.
DISTURBANCES
If a fault occurs during use of the system, please
disconnect all live lines from the device and contact
the manufacturer or your dealer.
Display does not light up during the day despite
connected photovoltaic modules: Please contact your
dealer.
Check Output X: The switching device searches for a
suitable load. This can occur especially in very poor
lighting conditions (eg sunrise and sunset). In this
case, less power is available from the photovoltaic
modules than the consumer needs to switch on/
operate.
