For 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

Yes, there is fully patched firmware version 74.40e. 
I've not seen any more recent firmware for this model, and in any case if there was, it's pretty much guaranteed that it won't have the premature float bug fixed.

Mains off, PV off, inverter off and lastly batteries. Then batteries on, inverter on and then the rest. Some TL inverters only load the new settings after a reboot

Thanks Guys
I just downloaded the patched firmware, going to try it. According to another post, this version has the ability now to do equalizing at program section 33 to 37 and 39.
don't know how true it is. Will give it  a go in the next few days and see if it's true
