4 Installation and commissioning

4.1 Unpacking the pyranometer

4 Carefully remove the pyranometer from the packaging.
4 Check that the delivery is complete and undamaged.
4 If you find any damage or if the delivery is incomplete, immediately contact the supplier and
manufacturer.
4 Keep the original packaging for any further transportation.

4.2 Planning installation

For the solar irradiation to be measured in the entire photovoltaic system, it is necessary to position several
pyranometers in the system. The number of pyranometers required depends on the system's performance and
ambient conditions.

4.3 Electrical connections

4.3.1 Power connection

The minimum supply voltage for the pyranometer is 10 VDC. To ensure reliable performance, a voltage of 12 to
24 VDC is recommended. The pyranometer is connected to the power supply using a power supply unit. For the
power supply unit, it is recommended to protect the outlet using a quick-acting fuse with a maximum of 1 A.
