there are two places to set this up so make sure you have set BOTH areas up, option is in the VE config Inverter tag and the other is in the ESS assistant under assistants

these are my settings and you may have to set it up on BOTH inverters not just one as I dont have two units (so check this area out some more)

This doesn't help.
Please provide the diagrams from the 'Advanced' page at least: dc voltage / current + SOC

Another possibility to look at


The length of the Battery cables to EACH unit, They must be the SAME length

just maybe one of the cables is longer and causing a issue.


this is just a thought and something to check
