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.

The modular SOLARCHECK system for PV string monitoring includes a range of devices for current and voltage measuring and a corresponding communication module.
The communication module collects the values from the measuring modules and transmits them to the central control system. It is also used to supply the measuring modules in the field. The communication module is simply integrated into an existing network as a Modbus/RTU device.
In a current measuring module just 22.5 mm wide, the parameters of your PV systems are determined on a contact-free basis with the aid of Hall sensors and forwarded to the communication module. 4- and 8-channel versions are available.
You can measure DC voltages of up to 1,500 V DC with the voltage measuring module. The module is suitable for measuring in both grounded and isolated PV systems. You can also flexibly use the voltage measurement outside the monitoring system as a simple analog device.
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.
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).
