Hi Robert,
I am close to going crazy on trying to get my Solis RHI-3P10k-HVES-5G to answer via Mobus. No luck at all! Reading out the Acrel Meter was quick and workig right away. But my Solis: no way!
After I had used a commercial modbus to lan adapter, I have now tryed to go with an D1 Mini with ESPhome. Again: Acrel - no problem. Solis Inverter - nothing!
I am using the Modbus Register Document von Ginlong ( RS485_MODBUS Communication Protocol
Translated on 2021.5.6).
You wrote that you do have a working configuration. Would you be able to share that?
There must be something I am missing here…
Many thanks!
