9.2 Example 2

– SCK-C-MODBUS installed centrally in the inverter station

– SOLARCHECK current measuring modules and voltage measuring modules are in-

stalled in the string combiner box in the PV field

If the voltage is to be measured at string level, it is advised to position the voltage measuring

module in the string combiner box. In this case, the analog input of the SCK-M-I-8S-20A cur-

rent measuring module, which is specifically designed for this purpose, can be used for the

power supply and data connection of the SCK-M-U-1500V voltage measuring module. A

separate power supply for voltage measurements does not have to be provided here either.

Likewise, the voltage data is available via the SOLARCHECK protocol.

Of course, it is possible to equip only one or just a few string combiner boxes in each system

segment with the additional voltage measurement components, as the string voltage in the

system segment is usually the same throughout due to the parallel connection.
