Set charge current and absorption voltage but next day different values

[vallesj]

Using Growatt SPF3000TLLVM-ES, EW new 52v 100ah cabinet battery and solar assistant. Recently got the EW battery, and connected it to my inversor using LI settings, and absorption voltage changed to ~58 v and charging amperes on grid from 0 to 50A. I changed the settings back on grid charging current to zero. But wanted to change absorption voltage to 56.8v since on LI is not possible. again Changed from LI to user, and usr2, changed the voltage to 55.2v to avoid OV error from battery and get better absorption but next day I checked voltage was again at 58v. Disconnected comms cable from battery to inversor, and still parameters changed. Disconnected cable comms from battery to SA, and still same behavior. Right now I am using the battery as dummy, but inversor still changes parameters values overnight, but now battery charging current is changing to 0A. It is SA responsible, since I discarded battery by disconnecting all communications? It is the growatt? Last option I am considering is to reboot the growatt completely, and see if that fix the issue. Somehow overnight the settings are changing, and SA is also suspect, because and automation I had to change from solar to grid at night and that change may be moving the other parameters... I may have to reboot SA as well.... is there a log on SA or the growatt to see when those parameters are changing? (Maybe I can find out what conditions made the changes)

If someone experienced a similar issue and found out the cause, your help will be appreciated

Wonder if it has 2 different profiles - one when comms is hooked up and one when not. My guess is that without the data it needs from the battery coms, it goes to whatever the default is.

Just for anyone that search for an answers on a similar issue; i completely disconnected the growatt, no grid, no battery and no pv, and the sa also got disconnected since it is connected to the growatt. Waited a minute and connected everything back. The following day no more changes on the parameters. I suspect that when I connected the communications from the new ew battery some of the parameters transferred from its bms where kept by the growatt no matter I latter changed it from LI settings to USR/USR2.

so it's working now, and that's how you got it to work for you (disconnecting everything)?
