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 Wi-Fi adapter is correctly and securely connected to the inverter, making
-
sure to tighten the two cross-head screws provided.
Check that the Wi-Fi symbol is present in the top right-hand corner of the inverter's
-
display (steady or flashing).
