RS485 cabling – simply without obstacles

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.

Technical Data



Wireless-based data transfer over long distances

The particularity of the innovative set: it transfers the data via radio  technology with a point-to-point connection and needs no additional cabling between these two points. The set's radio module has a long range and can transport data up to 500 meters away.

The separate antenna is ideally suited for outdoor installation; therefore, you can achieve an optimal range in a few steps and you avoid radio wave absorbing materials such as thick concrete walls.

Simple: quickly installed and preconfigured
From the radio module to the wall powWireless-based data transfer over long distances power  supply – the Wireless-Set485 has everything needed for commissioning. The additional quick installation poster ,which is included, will  help you  with the simple and easy installation close to your SMA devices. The Wireless-Set is already completely preconfigured by SMA, therefore no further software settings are needed. This means: saving time and costs.

Flexible: data transfer at any place of use.

Further advantage for your clients: no socket is needed  for the power plug in the vicinity of the radio. The voltage is provided by using a power injector via the data cable. The power injector can be up to 30 meters away from the radio module. In this way you can place the module in a way such that it achieves a maximal range. This allows for contact between two  installation sections even in hard-to-reach areas.

Two sets – for any requirement

The Wireless-Set485-01 includes the basic equipment for the connection of two elements in a solar plant.
The Wireless-Set485-02 uses the already existing power injector of the first set and it is specially configured so that parallel operation with the fi rst set in easily possible
