9.3 Example 3

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

– SOLARCHECK current measuring modules are installed in the string combiner box in

the PV field

– Higher-level voltage measurement for each system segment

As already indicated under example 2, the typical parallel connection of strings in large pho-

tovoltaic systems means that the voltage within one system segment is usually the same.

This means that voltage data can be acquired very effectively and economically. Voltage

measurement via the SCK-M-U-1500V voltage measuring module can also be used outside

of the SOLARCHECK device topology.

In this case, the device is used as a simple analog device in the string combiner boxes. In

this scenario, the power supply and data connection for the device must be implemented

separately. This method of use is very inexpensive, as only one voltage measuring module

is required for each system segment.
