Hello!
I have a Growatt SPF 5000 ES to which I attached 4 Sorgeti 12 SBF 100 batteries ( https://sorgeti.ro/baterie-stationara-sorgeti-sbf-100ah )
Unfortunately, I am not able to reach the correct values for the b2ac and ac2b voltages so that the batteries can only be used in the absence of mains and generator voltage.
The generator starts normally in a maximum of 10 seconds.
Any idea that can lead me to the desired result is welcome.
Thank you!

Leaving the default values of 54V and 46V respectively on a sunny day, the inverter had 20 KW produced and 37 imported under conditions where the average consumption is ~ 1.7KWh. (battery overcharged)
 
try to ask the battery manufacturer if the battery is able to communicate to the Growatt SPF 5000 ES, Growatt supports RS485 and CAN comms...
