Problems / No ModBus connection on regular LAN-Port

[MIRR23]

I currently also use SunGather, but there are problems with 2 inverters (both SH10RT) and a long-awaited update is unfortunately waiting. I have now found this really cool way to read the data, which has everything I need and more. With ModBus I am not so knowledgeable, but that will be with time.

Big problem: I can not read the data reasonably, no matter what I do...

• Direct LAN port at the inverter --> ModBus connection error
• LAN port via WinNet-S --> not all data available, aborts again and again
• Wifi via WinNet-S --> this works surprisingly best, but not all data available and always aborts.

I have tried everything to use the normal LAN port:

• Soft and hard reboot the inverter
• unplugged LAN cable for 10 min and for 2 hours
• Changing the ports on the switch
• Tried LAN connection with WinNet-S (as described in issue #94 ) and also WLAN connection

Is there anything else I can do???

Did you use the correct IP address for the LAN port connection? LAN port has a different address than the LAN port within Winet-S adapter.

[MIRR23]

Yes I did. I actually tried all 3 IP addresses of each inverter (LAN, LAN over Winet, WLAN).

After quite many restarts I somehow managed to get Modbus data from the first inverter. The second one still it is not working. Could there maybe be an issue with master/slave configuration?

Any updates?
