June 24, 20224 yr Hi Guys, I have an issue that I can't seem to get my head around. I have had a single Axpert King running with my Pylontech batteries using the RS458 cable and PYL enabled without any issues for over a year now. I have now added a second Axpert King as a slave and I just cant get communication between the Pylontech and the inverter. Is there something that I am missing ? The inverters both reads the SOC as 60% but the data stream that I am getting from the console port shows them at 100% Main CPU version on both inverters are 00072.00 Note inverter 1 and 2 SOC vs Pylon SOC on the attached screenshot. UPDATE!! I have now set the first inverter to PYL and the second to user as someone mentioned this on another forum but it is still not working for me. Thank you kindly Edited June 24, 20224 yr by Zane

However, it's the "display" firmware that talks to the BMS, so those might not be up to date. You would want at least removable display firmware version 02.66.
July 4, 20224 yr Author Thank you, This issue somehow resolved itself. I just left the cable connected with my first inverter set to PYL and it started communicating after some time.
