The characteristics of different communication methods of inverters are obvious, and the application scenarios are different. In order to better weave the underlying network of energy digitization and intelligent development, choose the most appropriate communication method according to local conditions.
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).
The data signal is connected to the low-voltage busbar through the power line on the AC side of the inverter, the signal is analyzed by the inverter supporting the data collector, and the communication is finally connected to the local power station management system or the cloud platform through the LAN or the Internet 2. Application scenario 4.
There are different modulation schemes used in power line communication. In narrowband application On-Off-Keying (OOK), Frequency-Shift-Keying (FSK) and Orthogonal Frequency Division Multiplexing (OFDM) are the most common modulations, while in broadband PLC mainly OFDM is used.
