Which power line communication options are implemented in different solar installations?
Figure 1 shows typical power line communication options implemented in different solar installations. These installations can be divided into communication on DC lines (red) and communication on AC lines (blue).
Why is wired communication important for Solar System monitoring & safety?
With the increased number of solar installations, importance of system monitoring and safety rises. In this trend, wired communications play a key role. Safety standards like SunSpec® Rapid Shutdown (RSD) which support NEC 2014, NEC2017 and UL1741 module-level rapid shutdown are built on wired communication interface.
How does an inverter communicate with a monitoring platform?
The communication between the inverter and the monitoring platform relies on a communication protocol in terms of software and mainly uses a monitoring stick module as a medium or bridge for data transmission and reception in terms of hardware. This ensures that the inverter's operation can be displayed on the monitoring and maintenance platform.
What frequency bands are used for power line communication?
International standards and norms specify the frequency bands which can be used for power line communication. In general, there are two categories, narrowband - and broadband - PLC. Narrowband PLC uses carrier frequencies up to 500 kHz. Table 1 shows the available frequency bands for different regions.
