Communication between 5kva Livoltek Off-grid inverter with a Dyness Lithium battery wall mount.
Communication cable pinout on inverter side 1 and 2 Can, Battery side 4 and 5 can. Dip switch 3 up on the battery. On the Livoltek app go to settings,basic settings , Battery setting, set to Lithium battery, restart battery if battery is on, wait for about a minute or so communication starts, inverter starts to charge battery immediately if battery is low. Hope this helps someone out there regards.
