Greetings!
I’m using Solis2MQTT (here) with a spare Pi Zero W and RS485 adapter to receive information from my 5G Solis inverter. It’s working really well.
However, the GitHub page and config file has mappings for the earlier 3G versions and I’ve not had much luck in finding information about the 5G mappings and which ones to export to HA.
The 5G documentation is here
If any one comes looking, this is what I have so far.
I have some battery information coming through to HA now which needs tidied up with some templating, but not all of the battery information seems to get sent from the inverter so is commented out just now.
If anyone has any feedback, I’d be happy to learn from you

I know this is an old thread, but I’m having issues connecting to my S6 inverter, I’ve been trying for literally hours!
I’ve tried different wires, different usb adapters and none are working. All I get is ‘inverter not reachable’ when running Solis2MQTT.
Did you get this error when the mappings were wrong?
Thanks!
Hi, nope.
Put some pictures up?
Pictures above. I’ve got the exceedcon plugs, soldered the wires in and connected to my adapter. I have tried with another adapter too, and swapped the A and B wires around too. No matter what I do, I just get ‘Inverter not reachable’ and then nothing else.
Any help would be greatly appreciated!
What are you plugging the usb adapter into?
A Raspberry Pi 4 that has nothing else installed on it except solis2mqtt
I’ve managed to get it to work! I had been trying in my Series 6 inverter and had no luck, but trying the Series 5 inverter worked straight away. I’ll contact Solis and see if I need to do anything different with the Series 6 inverter.
Did you ever get the battery stats to pull through? Everything is working for me except them.
Yep, which registers are you reading?
Sorry for the delay. I’ve moved away from this, as my installer needs the WiFi stick connected to maintain the warranty. I’m looking into other ways now!
