I ran into the same problem: my 8kW Deye inverter became very unhappy with the generator on the input. So, inspired by PaulinNorthcliff's remark above about 'fiddling with the throttle' I set about finding my generator's speed control, and soon found it, by pushing and tugging on springs and levers (with the generator running) until I found something that affected the speed, and tracing that to a set screw. Then, with a heater drawing a few kW to load it down (directly plugged into the generator, not connected to the inverter yet), I monitored the frequency - it was about 53Hz under load - and adjusted it down to 50Hz. After this I unplugged the heater and flipped the switch to connect the generator to the inverter input. And as PaulinNorthcliff suggests, we set it to draw well below the generator's rated output capacity. Because the inverter presents a constant load, the generator now maintains a reasonably stable speed, and happiness reigns supreme.

My goodness, what a prompt reply!
I have actually been using the dev version (2022.02.22d-0.1.3). On the 'Configuration' tab of the addon I have the following, for now:
PORT_URL: serial:///dev/ttyUSB0
SUNSYNK_ID: '2009074307'
SENSOR_PREFIX: SS
SENSORS:
  - pv1_power
  - battery_soc
  - battery_power
  - inverter_power
  - inverter_frequency
PROFILES:
  - system_mode
MODBUS_SERVER_ID: 1
MQTT_HOST: core-mosquitto
MQTT_PORT: 1883
DEBUG: 2
 
If I now restart the addon, the log window shows the following:

No further communication occurs, so I assume I should set something to make this happen? And why does it say 'retained msg'? I very much suspect that I got old readings this time round, as I often do.
Do I put something in the configuration settings, or is it elsewhere altogether?
Thank you very much for the massive amount of work that you have put in, and share so freely with the community.
