Solar power station communication cabinet and inverter ratio

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).

What are the characteristics of different communication methods of inverters?

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.

Should a PV array be oversized for a given inverter capacity?

Rather than focusing on how much the PV array should be oversized for a given inverter capacity, the installed inverter’s nominal power has been optimised for a given PV array installation. This allows us to compute the optimal ILR.

What is the optimal inverter rated power?

The analysis shows that energy clipping occurs at 5.22 MW, which is the optimal inverter-rated power. Only the generation above 5.22 MW is clipped, and the energy below this threshold is used to calculate the estimated annuities of the system revenues. It is important to note that this study has only analysed typical annual hourly generation data.
