Diagram from the manufacturer manual, titled Figure 3-35 Communication Connection Interfaces. Technical line drawing of the inverter with a large circle enlarging the communication board at the top. Labels on the board: RS485-1, RS485-2, CAN, DI, DO. Numbered callouts: 1 points to the RS485-1 terminal, 2 to the DI terminal, 3 to the DO terminal, 4 to a small circle at the right showing the switch S2 (labels OFF and ON, the black slider is at the OFF side), 5 to the USB port at the left side of the board. Below the figure a table with columns No., Name, Description. Row 1: RS485-1 P170; (From right to left) 1. GND, 2. RS485-1 B, 3. RS485-1 A, 4. GND, 5. RS485-1 B1, 6. RS485-1 A1. Row 2: Reserved; function not available. Row 3: Reserved; function not available. Row 4: Selection Switch (S2); 120Ω terminal resistor switch for communications. ON: Enable termination resistance. OFF: Disable termination resistance. Row 5: USB P153; Firmware upgrade.

Diagram from the manufacturer manual: a row of inverters drawn as line drawings with the CPS logo, numbered 1, 2, 3, then dots, then n. Below each inverter is the switch label S2 with its position: first inverter S2 ON; second inverter S2 OFF; third inverter S2 OFF; last inverter S2 ON (with a small arrow pointing at it). Lines run along the bottom from each inverter to the next, showing the communication daisy chain between all inverters.

Diagram of the FlexOM Gateway module connections. Top: block Inverters with three blue squares labelled Model A, joined by an orange line; solid orange line between the first and second, dashed orange line onwards, labelled Daisy Chain (up to 32 devices). An orange RS485 Cable line (label RS485 Cable) runs from the first inverter down to the gateway board, drawn as a circuit board. Label B (green circle): 5-PIN Port for External DAS Box Installation, pointing to a port on the board. Label A (green circle): 6-PIN Header for Communication Board Connection, pointing to a header on the board. A green Ethernet Cable line runs from the board's Ethernet port to a cloud labelled CPS Portal, and down to a monitor icon labelled 3rd Party Data Logger / SCADA. A dashed black line leads from the data logger to a cloud labelled 3rd Party Portal.

Screenshot of the left sidebar of the Reduxi Configurator. Top: reduxi logo with the text CONFIGURATOR. Collapsed sections: Devices (plus icon) and Strategies (plus icon). Below, two buttons side by side: Add device (plus icon, marked with a blue highlight box) and Add strategy (plus icon). Below them two entries: Settings and Profile. The area to the right of the sidebar is empty white.

Screenshot of the Reduxi Configurator add-device wizard, step 1 of 3. Progress bar with three steps: 1 Basic settings (active, black circle), 2 Communication channel (grey), 3 Advanced settings (grey). Heading: Basic settings. Fields: Device type * : empty dropdown; Type * : empty dropdown; Name * : empty text field. Buttons: Back (bottom left), Next (bottom right, dark).

Screenshot of the Reduxi Configurator device wizard, step 2 of 3. Step indicator: 1 Basic settings (done, black), 2 Communication channel (current, black), 3 Advanced settings (grey, not reached). Heading: Communication channel and device configuration. Fields: Connection: TCP/IP (dropdown); IP: empty; Port: 502; Modbus unit ID: 1; Read optimizers: toggle off, labelled No. Note below the toggle: Measurements from optimizers are only available on MQTT and other connectors. When readout from optimizers is enabled, battery and solar regulation is only possible in 30-60 seconds interval. Buttons: Back, Test communication, Next (black).

Screenshot of the bottom button row of a Reduxi Configurator form. Left: button Back. Right: button "Test communication" marked with a blue box, and a dark button Next to its right.

Screenshot of the Reduxi Configurator add-device wizard, step 3 of 3 (Advanced settings). Progress bar with three black circles 1 Basic settings, 2 Communication channel, 3 Advanced settings (active). Heading: Advanced settings. Eight yes/no questions, each with a toggle that is off and a small default hint at the right: Do you want to set data-saving interval? (Default: 1 min); Do you want to set reading delay? (Default: 1000 ms); Do you want to set writing delay? (Default: 1000 ms); Do you want to set power generation limits and capabilities?; Do you want to set power consumption limits and capabilities?; Do you want to limit communication with the device to read-only? (Default: No); Do you want to invert direction for energy import and export? (Default: No); Do you want to exclude device from summary? (last question, small text; Default: No). Bottom row of three dropdowns: L1 is connected to main feed: L1; L2 is connected to main feed: L2; L3 is connected to main feed: L3. Buttons: Back (left) and a dark button at the right (label small, reads Done).
