VNT Wireless String Combiner Boxes are ideal for MW scale land-based Solar Photo-Voltaic (PV) applications and systems these devices are used to combine the photovoltaic string along with the monitoring of each string.The individual string currents are accurately measured through �Shunt Based Technology�. Any mismatch is promptly detected by the system supervisor and communicated to the inverter to allow for quick identification of any fault of the solar panels. All String Combiner Boxes include surge protection with removable elements as well as fuse protection for each couple of string channels. It is available with an optional fully-integrated Dc Switch, Fuse and Remote controlled DC disconnects function.
