Hi Guys, just an update. I have managed to get it working. @YellowTapemeasureThe unit does have a console port but now they use a RJ45 connection. My frustration is dropping 20k per battery and the vendor does not want to know you in terms of support. Frustrating. Anyway the pinout is as follows for anyone else looking for it:
RJ45 CONNECTOR:-------------- > DB9 RS232
PIN 1 -------------- > NOT CONNECTED
PIN 2-------------- > NOT CONNECTED
PIN 3-------------- > PIN 2
PIN 4-------------- > NOT CONNECTED
PIN 5-------------- > NOT CONNECTED
PIN 6-------------- > PIN 3
PIN 7-------------- > NOT CONNECTED
PIN 8-------------- > PIN 5
Yani from Multisib had to make an update on his brilliant program and now Multisib communicates with Pylontech and Invertor flawlessly. 
Thanks @DeeJayand @YellowTapemeasurefor your valuable feedback.

Thank you so much for this information, I have 3 US3000B bateries and bought another one, but instead of them sending me a B they sent me a C!!!
 
I had a RJ11 to DB-9 Serial to usb going into a rapsberry pi for ICC Solar, and it wasn't a pleasant surprise to see that they changed the console port from rj11 to a rj45, even if the RJ11 fits It doesn't work on the C
 
Then I had the idea of making the C battery a Slave (and just conect the RJ11 on the B Master) but that doesn't work because apparently the C has to be the master if you have any Bs
 
Anyways I did the cable and it works perfectly with icc, here's a more visual thingy if you wanna make it and wherever your db-9 port is male or female:

Hi Plaashaas, 
 
I made it myself. very easy. Get a serial cable, chop one end off and connect pins. Found diagram on this site will post link.
