Technical datasheet Electrifying Innovations REFU connect Lots of data - no cable ■ Intelligent wireless network ■ Easy communication links ■ Flexible installation options The REEUconnect radio module ensures wireless communica- tion between all inverters in a PV system. It can network to- gether up to 2000 inverters and transfer their data REEUconnect uses a radio standard, which also establish- es and maintains secure and reliable connections even in high-interference industrial environments. In this context, the module is simultaneously used as a repeater, so that distances over several kilometers can be bridged without difficulty. The range of such an individual connection can total up to 300 m The radio modules have very low power consumption and are supplied directly by the inverter. The network is password-pro- tected. This means that data is transferred securely, remaining invisible to non-authorized network participants.
