Solis DLS-W not working

[ishanfdo18098]

Inverter - Solis S6-GR1P4.6K Datalogger - DLS-W

I am currently registered in the soliscloud website and the solarman website and both work perfectly.

I tried the utils/solarman_scan.py script and it doesn't output anything

ishanfdo@Dell-Inspiron:/mnt/c/Users/IshanFernando/Desktop/tmp/pysolarmanv5/utils$ python3 solarman_scan.py 
ishanfdo@Dell-Inspiron:/mnt/c/Users/IshanFernando/Desktop/tmp/pysolarmanv5/utils$ 

Datalogger site http://datalogger.ip/config_hide.html works,

Ran the register_scan.py script and it shows,

Scanning input registers

Ran the first print() in the client_example.py and it shows the 1010 value

ishanfdo@Dell-Inspiron:/mnt/c/Users/IshanFernando/Desktop/tmp/pysolarmanv5/examples$ python3 client_example.py 
[1010]
ishanfdo@Dell-Inspiron:/mnt/c/Users/IshanFernando/Desktop/tmp/pysolarmanv5/examples$

But I feel like the value doesnt represent anything.

Any help will be much appreciated with my issue.

On the config_hide.html page did you see the Internal Server setting? If this is missing then I suspect your dongle isn't compatible.

[ishanfdo18098]

I can see the same options in the config page

[ishanfdo18098]

Do I have to select anything for the mode ?

[gedger]

You don't need to change any parameters in the inverter settings, you edit the register_scan.py file and enter the IP address of your inverter, the serial number of the Device (not the inverter) and the port of 8899.

I've just checked and your dongle has identical firmware to mine so it will work.

Double check you can ping the inverter from the machine running the python code to ensure the IP connection is OK.

[ishanfdo18098]

you edit the register_scan.py file and enter the IP address of your inverter, the serial number of the Device (not the inverter) and the port of 8899.

Yes. In examples/register_scan.py line 8 I changed the IP to the dataloggers IP, and the serial number to the number written in the datalogger. (The first image in opening post. starting with 409......... 10 digits )

Double check you can ping the inverter from the machine running the python code to ensure the IP connection is OK.

changed the verbose to True in the example py. There I see that the datalogger sends a reply.

modbus = PySolarmanV5(

Still only one register is available and 1010 doesnt correspond to anything.

Looks to me like it's working now as you had socket timeouts in the first post. You now need to find your registers. My Solis inverter starts at 2999 for both holding and input registers.

I contacted Solis support and asked for the modbus register specification for my inverter model, it took 2 months but they did supply this document.

[ishanfdo18098]

2999 ? All this time I was searching from 30000 to 39999 which was the range in the example.py 🤣 I will do a scan around that numbers and see.

Thank you very much for your help

[ishanfdo18098]

2999 for both holding and input registers.

Thank you a lot. You saved my day

[gedger]

Try my inverter settings they may well work for you.

Even better 🥳 Thanks a lot

[ishanfdo18098]

but they did supply this document.

can you send me the document ?

[gedger]

There's several versions floating around, every inverter seems slightly different although the core seems common.
