Hi
I have a Solax x1 g4 5kw Hybrid inverter (working well powering the house) I have purchased 3 Pylontech us3000c batteries to store the surplus power generation, My issue is following every instruction in both the Solax and Pylontech manuals the inverter will not recognise the batteries, The original cables (bought from Pylontech) wont communicate, in either can or I have re wired the can cables and changed the Baud rates, so they match (and tested the cables on a Rs485 tester ensuring correct pin outs)
There has been no response from Solax or Pylontech and very little information on the web, I have found a couple of posts with the same issue,
apart from buying a new inverter, does any one have any (suitable suggestions?) Or have had similar issues that may be of help?

Kind regards
 
Hey, supporting here.
I'm trying to connect to a pylontech SC0500 and cannot manage to have a working setup.
However, after a few spying, the CAN link seem to work, but nothing on the RS485.
And when the X1 detects the bms, then after 30 secs I get the IE 07 bat volt fault. and cannot go further...
I contacted Solax and they just claim the battery pack to be faulty (although the rs232 debug log is clean ...)
