Modbus address
Select “9. ModBusAddress” and press “OK” to enter the menu for selecting the communication address. Use
the “Up” and “Down” keys to select the number and “OK” to move to the next one, and confirm. After setting
the address, press “OK.”
The Modbus address indicates the address used by the inverter to send its data to the monitoring server.
Address 01 is used for single inverters; to extend the monitoring to multiple inverters, use progressive
communication addresses.
Note: make sure that the address entered is never 00, because this setting would exclude the possibility of
communication between the inverter and the Wi-Fi network or RS485 port.
Set MPPT
Selection of the input mode: 3PH 20000TL - 33000TL-V2 inverters are equipped with two MPPTs, which can
operate independently or in parallel, depending on the requirements of the system in which they are
installed. The input mode can be set by the user via the LCD display.
Select “10. MPPT” and press “OK” to enter the menu for setting the input mode. Press the “Up” and “Down”
keys to change the input mode between “1. Parallel” and “2. Independent,” then press “OK” to confirm. If the
setting is successful, “OK” will be displayed; otherwise, “Error” will be displayed.

Select “11. Language” and press “OK” to enter the menu for selecting the language. Select the language using

A faster way to change the language is to press the “Menu/Back” key and the “OK” key at the same time. In
