PV Floating DC Combiner Boxes

String monitoring with Transclinic Product innovation

Inside our PV Floating DC Combiner Boxes the Transclinic xi+ series continuously monitors the power from single strings or groups of strings as well as the voltage of a Photovoltaic system and thereby permits detailed monitoring of the system. Negative influences, which lead to reduced output, can be detected immediately allowing rapid repairs or adjustments to be made to the system.

Special features:

• Various monitoring options - As standard, single strings with up to 16 inputs and a maximum Isc of 10 A per input can be monitored. For monitoring solutions of more than 16 inputs, double line monitoring is possible.
• Efficient double line monitoring - With double line monitoring, two lines can be monitored via one channel. This reduces the number of connections required, the amount of components in the enclosure, the size of the control cabinet and thus also the costs. The maximum Isc per channel is 25 A.
• Reduction of maintenance costs - All wiring is done with PUSH-IN connectors. There is no need to check the torque as required with screw connections. No further connection testing is necessary during the entire service life of the system.
• Reliable even under extreme conditions - Transclinic 16i+ 1k5 H allows the measurement of 25 A per input even at 70 °C with an accuracy of ±1% (voltage/current). This helps pair monitoring in combiner boxes in difficult environments by using only one string monitor and optimising the cost of the solution.
• RS485 SPD on board - A specific overvoltage protection for RS485 interfaces is already integrated to increase robustness and reliability of the device throughout its operational lifetime.
