I have 4 solar panel and 8kva inverter plus us3000 lithium battery. If I put again 4panel and us3000 lithium battery the setting will change of remain the same plus help 

 

 

If the new set of for 4panels is just going to be added to the existing in parallel it will just be more current that is available.
In theory the charge settings will stay the same, but the max charge current should be able to increase. (35A -> 70A if I remember correctly)

Are your Pylontech US3000 connected to the inverter with a comms cable? What inverter are you using?

 

Hi please can some one help me I'm failing to connect the hoselect lithium battery to inverter luxpower tek
