Hi there,
Trying to figure out the best battery setting on an inverter deye sun-8k-sg01lp1-eu for a 16 x EVE 304 bank.
Battery specs:

Here my calculations and my config settings at the moment:
1. Battery settings ONE
Capacity= 304ah x 16 =4864ah (First image is wrong)
Batt Mode = Use Batt % (First image is wrong)
Max A Charge = 190 A (Actually limited by the inverter capacity 8000w)
Max A Discharge = 190 A (Actually limited by the inverter capacity 8000w)
* Most likely I will disable float charging

2. Battery Setting TWO
Custom setting to select when Low Battery SOC is reached and also how to charge the battery

3. Battery Setting THREE
This is where I am a bit more confused as how to define the battery levels for the charging phases.
Floating Voltage = 16 x 3.375v = 54v
Absortion Voltage = 16 x 3.65V = 58.4v
Equalization Voltage = 16 x 3.65V = 58.4v
Equalization days = 90 days (is that relevant?)
Equalization hours = 0 hours (is that relevant?)
TEMPCO ?? Not sure how to set this
Battery resistance = 8 mOhms (from specs)

Any help on my calculations is most welcome!
Thanks
