Why choose wireless SMUs over cabled communication?

Wireless eliminates most trenching and long cable runs, speeding up commissioning and cutting CAPEX/OPEX. It’s also ideal for retrofits—instrument strings without new conduits or civil works.

Is wireless reliable enough for IEC 61724-1:2021 Class A monitoring?

Yes. Our system is designed to meet Class A requirements with sub-minute data storage, robust EMC performance inside combiner boxes, and a mesh network that delivers measurements and status signals (e.g., switch disconnector) quickly and redundantly.

How does a wireless mesh scale on utility-scale plants?

The network is self-forming and simple to expand: add combiner boxes and the mesh adapts—no new communication cable needed. This makes phased builds and future extensions straightforward.

Where does wireless deliver the biggest advantage?

Sites where trenching is hard or costly—floating PV, rocky terrain, brownfields, road crossings, or long distances between arrays. Fewer cables also means fewer field failures and faster fault isolation.

How does wireless data reach SCADA or the cloud?

In our architecture, the wireless network master is the DM-108. It aggregates string data from the SMUs and exposes it via Modbus RTU. From there, you can either use a standard Modbus RTU-to-TCP converter to feed SCADA, or route data through any of our Industrial IoT gateways to SCADA or the Concordia® Industrial IoT Cloud for real-time dashboards and analytics.

What sensing technologies and configurations do your wireless SMUs support?

We offer two series: one measures string current with shunt technology and the other with Hall-effect sensors. All SMUs also measure string voltage and can read temperature, solar irradiance, wind intensity, and the status of breakers and SPD devices. Channel options include 8, 12, 16, 20, 24, and 32 strings, and all models are designed for 1000 VDC and 1500 VDC PV applications.
