DC PLC protocols monitor solar panels and control motors. G3-PLC, PLC-Lite, and IEEE 2847-2021 are key protocols. Specialized chipsets are cost-effective, except for IEEE 2847-2021, which uses software.
PLC transmits data over power lines, using high frequencies for dual power and data transmission. Applications include smart meters, street lighting, and home automation, with speeds up to a few Mbps over 6 miles.
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.
