9 Installation examples

Here you will find some typical installation examples for medium to large photovoltaic sys-

tems. The examples are schematic and simply illustrate a few possible installation options.

The modularity of the SOLARCHECK system allows for many other arrangements and com-

binations. SOLARCHECK is a very flexible system which can be effectively incorporated

into many system designs, making inexpensive solutions possible.

9.1 Example 1

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

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

the PV field without voltage measurement

The conventional arrangement involves installing the communication module at a central lo-

cation, which allows for the advantages of the modular system structure to be demonstrated

to very great effect. As power is supplied to the measuring devices in the field via the

SOLARCHECK communication cable, a particularly efficient and inexpensive design for the

power supply of the overall SOLARCHECK system is possible.
