OTHER IMPORTANT NOTES

• Observe the maximum permissible voltage of the photovoltaic modules and the electrical loads to be connected.
• The connected loads must be compatible with the connected photovoltaic modules.
• The device must be installed in a dry place.
• Only one module per input may be connected to the limits specified in the specifications.
• Photovoltaic modules in parallel or series connection must not be connected to the system inputs.

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.

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 neighboring 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.

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 (+).
• 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.
