The data address received in the request is not an allowable address for the server.

[PitinoB]

I have LSW3 logger with FW LSW3_15_840B_1.36 on Lenercom hybrid inverter.
solarman_scan.py find logger correctly and print its ip, mac and serial.
When scan registers I got

umodbus.exceptions.IllegalDataAddressError: The data address received in the request is not an allowable address for the server.

Can enyone help.

This seems to be expected. The scanner is just an example. You should consult the documentation for the addresses supported by the inverter.
