Modbus TCP vs DNP3: Solar SCADA Protocol Guide
Key Takeaways 80 to 90% of solar plant field devices — inverters, trackers, weather stations — natively support Modbus TCP, making it the universal device-layer language for solar SCADA polling (Nor-Cal Controls, 2024). Most US utilities specify DNP3 (IEEE 1815) for the EMS communication link between a solar plant and the grid operator — it […]
Fiber Optic Installation Solar Farm: Direct-Buried vs Conduit
On a utility-scale PV project, fiber optic installation solar farm planning is not “just comms.” It’s the backbone that makes SCADA, DAS, PPC interfaces, revenue metering visibility, security systems, and long-term troubleshooting possible. As a result, the wrong installation method can look fine during early bring-up—then show up later as intermittent dropouts, hard-to-locate faults, and […]
