- Check the Modbus address set on the inverter:
Enter the main menu with the ESC key (first key on the left), go to System Info and press ENTER
to enter the submenu. Scroll down to the Modbus address parameter and make sure it is set to
01 (and in any case, other than 00).
If the value is not 01, go to “Settings” (basic settings for hybrid inverters) and enter the Modbus
Address menu where the 01 value can be set.
- Check that the 4G adapter is correctly and securely connected to the inverter, making sure to
tighten the two cross-head screws provided.
