I just installed a 6000xp and an eg4 14kwh indoor battery.
Everything worked as it should for 5 minutes. Then the ac output shut off for about 30 seconds, then turned on for 5 seconds it kept doing that for a few minutes then shut off the ac output entirely.
I can get it to work if I switch the settings to lead acid battery instead of lithium.
I tried the every lithium setting from 0 to 6.
A couple things that may be important: it is off grid, I dont have wifi avalable there(I do get cell service and could use my phone as a Hotspot if necessary), right now the building is unheated(the batteries were at 4c when I was trying to get ot to work.

Check for errors thrown by 6000xp.
Check for error logs on battery display
Does the inverter 'see' the battery when in lithium mode? if not check the comms cables.
Perform cold restart of entire setup while battery is in Lead acid mode.
Switch everything off (including battery BMS and all breakers and EPS) for few minutes and power Up the system starting from battery and its BMS then the inverter and BMS. After Inverter is back online try switching to Lithium Battery type 1.
Ultimately you might have to update firmware of the inverter and the battery.
See my other posts regarding wall mount battery communication issues.
Hope that helps

@joey Can you share some pictures of how everything is connected?
Are you getting any warning or errors?
For the inverter to communicate properly with the WallMount battery make sure the Lithium Brand is set to 1 and the battery's firmware is set to EG4/LUX.
