Now distance can be bridged easily: SMA’s Wireless-Set485 allows wireless contact between two sections of a PV plant with RS485 communication. It can be used where laying cable would be impossible. In this way, the Wireless-Set’s radio modules connect two buildings, for example. Overcoming construction obstacles like streets, railway segments or rivers can be now realized without underground cabling. The Wireless-Set covers a distance of up to 500 meters in an open field and can be flexibly applied in almost any case.
