Kvz reacted to Wilco in Growatt Inverter + Pylontech Batteries : BMS Comms GuideFor what its worth. I have installed a few growatt inverters with Dyness Batteries.
My settings on the ES is Li and protocol 1. Cable that I use is the black cable black boot on the in port on the battery and orange boot in the RS485 port on the inverter. Dipswitches 0110 on master and the rest 0000. This setup is working without a hitch
TL is a bit more finnicky. Also the same black cable with black boot on IN port on battery and orange boot in the BMS port.
Battery DIP settings 0110 on master and the rest 0000. With the TL you will have to play around with the protocols. setting is Li and protocol 1 or 2. Start with 1, powerdown the inverter completely and restart. error 04 will show for about a minute then dissapear. if you get an error 20 after restart try protocol 2.
PLEASE REMEMBER TO POWERDOWN EVERYTHING COMPLETELY AFTER YOU MADE CHANGES. it works, dont know why but it does.
hope this will help someone
