Yep, I ordered a 5K Sunsynk earlier this year and specifically requested the Sunsynk dongle, but it still came with Solarman dongle. The wholesaler refused to swop it out. I have managed to get another Sunsynk logger in the mean time, but I am still stuck with an unwanted Solarman dongle, which I advertised in the classifieds. It still leaves a bad taste in my mouth.

Installed my Sunsynk inverter today and the first (and only) thing I miss is the realtime information and integration with my Home Assistant.  Looking at the inverter it would appear like it is has modbus communication available on the RS485 port. 
I have ordered a USB to RS485 receiver to see if I can decode the the communication.  Once decoded I want to create a stand alone ESP8266 which will receive and translate the Modbus and communicate it in realtime via MQTT.  

Check that you dont have the inverter grid side feed after the earth leakage. It should be before the earth leakage(of non essentials) or it will cause an imbalance and trip the EL.
