Phoenix Contact offers a customizable marking system that addresses various PV-specific needs. Thermomark Card can print any kind of plastic labels in card and mat format. Thermomark Roll processes labels and heat- shrink tubing in specific formats or endless rolls. An outstanding feature of these printers is the high printing speed of eight seconds per card.The compact printers are built for use on the shop floor but also support mobile use at the construction site.The Clip Project Mobile Markers Simple and Professional Labeling of PV Systems planning and marking software is pre-installed on a robust notebook.The Plug & Play system is immediately ready for printing and offers a bidirectional interface to common CAE systems. The software also facilitates quick, direct entry of labeling data. The two-part monitoring system comprises a measuring module and a communication module. The compact 22.5-mm measuring module determines the current values of up to eight PV strings without taking up a lot of space. Measuring is performed with Hall sensors.The live cables are threaded through holes in the module during installation, meaning there is no need to disconnect the cables.This prevents the introduction of any further contact points, which would generate contact resistance and thus represent a potential source of error.The device also detects direct current voltages of up to 1200 volts, providing a constant overview of the installation's power and productivity. The communication module collects measurements from up to eight measuring modules and relays them to a superordinate controller as a Modbus RTU slave. Up to 31 communication modules can be integrated without a repeater, allowing for the reliable monitoring of almost 2000 photovoltaic strings.
