DC PLC

Modern energy systems use DC, especially in solar power. NEC mandates reducing solar array voltage to 30 volts in emergencies. Power Line Communication (PLC) enables safe, efficient control and data transmission, outperforming wireless and PoE in reliability and cost.

Power Line Communication (PLC) uses high frequencies to transfer data over power lines, allowing simultaneous power and data transmission. Initially used for dispatcher communication, PLC gained traction in the 1990s for internet access but couldn't compete with faster options. Today, it's used in smart meters, street lighting, and home automation. Despite challenges like interference and signal barriers, PLC remains a niche but essential technology.
