I have in use the sph6000 and diy lifepo4 batterry.
I use the lead-acid battery seting for this , but i manage the xharging/ discharging and protection with a daly bms.
If you will use this pair ,be sure to have the cut charge and disharge of the inverter set in such way that the inverter...
Maybe take a look at Groboost.
Into the documentation have seen something about pairing with a EV charge station.
Also it automaticaly adjust the load to not import from grid.
Have you tried to swich on/off the charging/discharging from daly app ? Sometimes is forcing the inverter to read again all batery settings.
Also see if the interval do not coincide with sleeping waiting time setting.
