Deye Parallel Charging Issue

[NightRock]

I have 2pcs of 12kw Deye Hybrid single phase running on parallel.. Master is fine all setting is copied to slave. But what I notice is slave battery is not charging but fully draining.. Im using lithium battery.. I switched the battery between master and slave.. battery seems fine only slave is not charging.. any help will be appreciated

I switched the battery between master and slave

Are you using two separate battery banks?
Why are they separate?

IIRC when inverters are in parallels then they must be connected to 1 battery

Yes each inverter has its own 300ah battery...

Deye has written in the manual that any parallel units must have a common batteri bank.
The blue one that came with the units.
