sungrow-sg5kd Modbus connection failed

[Flynsarmy]

I can see ports 80 and 502 open and can telnet into port 502 fine to confirm a connection can be made but solariot is giving a connection failed. Connecting via wifi. I've tried slave 0x01 through 0x04.

Wifi dongle v31_001_247:
Device address: 247
Device Model: Wifi V31
Manufacturer: Sungrow

Inverter:
Name: SG5K-D_001_001
Device Address: 1
Device Model: SG5K-D
Manufacturer: Sungrow

cat config.py

inverter_ip = "10.0.0.47"
inverter_port = 502
slave = 0x01
model = "sungrow-sg5kd"
timeout = 3
scan_interval = 10
dweepy_uuid = "random-uuid"

Returns:
./solariot.py -vv

Sounds like the same problem as #45? See also my discussion here #34.
