Can someone prvide some assistance connecting and setting up my new Growatt inverter with the Solax Modbus integration via Waveshare converter.
I’m struggling for some time now but don’t get it to work to get data into HA. The intergration continue to give errors.
I have:
- HA running on Raspberry
- Solax Modbus 2024.09.01 (HACS)
- Waveshare RS485 TO ETH (B)
- Growatt MOD 4000 TL3-XH inverter with 22-pins I/F connector
At the inverter I tried multiple RS485 pin pairs at the 22-pins connector and I’m still not certain what the correct pins are for connecting the Waveshare.
The Waveshare is perfectly accessible on the LAN.
To start, can someone tell me the correct RS485 pins to use at the inverter side?
