I am looking for help.
I have a 3kW 3000EHV-48 with 2 EG4 LL batteries I have everything working but I can not set for lithium batteries I have to set it for lead acid due to a 19 code saying communication problem between BMS and inverter. EG4 does not seem to be able to help me. I was having a problem with the communication cable inserting to into the battery.
ant suggestions would be appreciated.

Try cold restart of entire system including battery BMS (power down all components for several minutes while in lead acid mode) then power up starting from batteries and their BMS then start to switch to lithium.
Just my 5 cents
