Crosstalk in commercial rooftop PV systems—caused by electromagnetic interference in PLC-based communications—can disrupt Rapid Shutdown (RSD) signals, risking safety and compliance. Traditional string inverter setups with third-party RSDs require costly design changes, added wiring, and cable separation to mitigate this. SolarEdge’s DC-optimized solution integrates RSD into inverters and Power Optimizers, using unique inverter IDs to avoid interference. This reduces BoS costs, installation time, and labor, while enhancing safety and design flexibility. A 500kW case showed notable cost savings versus traditional solutions.
