Figure 3-9 Networking through DataHub
Note: The diagram of networking through DataHub uses the cascading of gird-connected
inverters for example, and the RS485 terminal of the master inverter for connecting slave
inverters and DataHub might vary depending on the inverter models. For wiring details, see
the user manual of the specific inverter and DataHub.
