SCK measuring module for monitoring photovoltaic systems, 1 x voltage measurement up to 1500 V DC, 1 x analog output (2 ... 10 V)
PV string monitoring
In PV system monitoring, PV string measurement plays a central role in increasing efficiency. Detect malfunctions and take countermeasures: the SOLARCHECK PV string monitoring system reliably provides you with information on the performance of your photovoltaic system. The system enables you to respond immediately to power losses in individual strings, which may be caused by damaged panels or defective contacts and cabling, for example.

Your advantages
- Low costs and wiring outlay, because an additional power supply unit is not needed in the device connection box
- Design flexibility with 4 and 8-channel versions for string boxes
- Space-saving installation with the compact design
- Easy integration into monitoring systems via Modbus/RTU communication
- Remote indication contact monitoring with an additional digital input
SOLARCHECK – PV string monitoring made easy
Feed the power cables quickly and easily through the openings in the measuring module. The two-wire communication cable is also used to supply the measuring modules with power. This means that you can supply up to 16 measuring modules with one communication module – without an additional power supply. With a width of just 22.5 mm, the measuring module bundles the cables in a small space. This saves space in your control cabinet. You can combine 4- and 8-channel current measuring modules to tailor the system perfectly to your application.
Application example: monitoring photovoltaic strings
The measuring system enables you to measure up to 64 DC currents and eight DC voltages at the same time. The complete system enables you to operate 16 measuring modules on one communication module. The two-wire communication cable is also used to supply the measuring modules with power. That means only one central power supply is required for the communication module for this system.
Automation and visualization
Use the continuous process data acquisition as well as the data management. In doing so, you enhance the efficiency and yield of your photovoltaic system. Automation and visualization tools from Phoenix Contact enable you to network free-standing systems throughout the world. This enables you to acquire and evaluate data at all times. The open register structure of the SOLARCHECK system enables quick and easy integration into your own software environment.
The communication module collects the measured values from the current measuring modules and forwards them to a higher-level controller via RS-485 (Modbus).
- Acquire up to eight or four string currents with one current measuring module each.
- You can connect a maximum of eight current measuring modules of any type to one communication module.
- The 2-conductor communication cable is also used to supply the measuring modules with power. This means that no additional power supply is required in the field.
- The voltage measuring module is connected to and also supplied via the analog input provided on the 8-channel current measuring modules.
- All measured values can be read from the communication module via open registers.
