Good Day Victron Community,
Last couple of days was sunnier than before, I hope it’s shining for all of you as well.
Today I realized that my standalone multiplus single phase system feed the grid after batteries became 100% full despite feed-in excess energy was disabled. No settings changed in last 30 days in the setup and feed-in was disabled from day one. But somehow Multi/ESS decided to push excess energy to the grid.
What i see from advanced statistics is, during the feed-in duration, the vrm stats shows Absorption as state but MPPT (VictronConnect) shows Bulk all day. I am not sure why they report inconsistent.
It might be a communication problem between ccgx and mppt but again, there is no error in the logs about it.
My system is running with below settings:
-ESS: optimized without batteryLife Minimum soc:%40
- grid setpoint 10W
-Feed-in AC/DC off
- There were no real load in last couple of days on the system and it was a sunny day. At around 13:40 the batteries fully charged and feed-in started.
Other settings:

And Devices and firmwares:

2 arrays of 3 serial connected 410w/48v, total 6 panels.
Any good guess about what may cause it?
Thanks.
