solariot: Sungrow SG10RT - "unable to decode request"

Just got a Sungrow SG10RT installed and my config.py looks like this:

inverter_ip = "192.168.1.120"
inverter_port = 502
slave = 0x01
model = "sungrow-sg10rt"
timeout = 3
scan_interval = 10
json_file = "telemetry.json"

Confirmed that port 502 is open on the inverter_ip. Log:

I saw another issue that mentioned using pymodbus version 2.4.0. I’m already on that version as per requirements.txt

Any ideas?
