Description
xThe Arc Fault Circuit Interruption Combiner Boxes monitor the current and voltage of each string and the temperature in an enclosure, the integrated automatic. contactors triggered when there is arc fault detected. So the PV DC strings will be shut down rapidly. The solution provides solar PV system safety. The DC contactors can be remote controlled for easier system maintenance.
This combiner box is used in large-scale photovoltaic plants and contains a high-level protection and monitoring circuit including the "firefighter" features. It will interrupt the power from solar panels in the event of a fire or a short circuit.
The internal microcontroller with current transformers (CT, sensor that monitors power generation from individual strings) registers the energy production from every solar PV string. This is useful for evaluating the performance of the panels and detecting potential faults from the underperforming ones.
If you have a specific requirement with a bespoke number of PV inputs and outputs, email us your technical specifications and we will customise the combiner box accordingly.
