My syestem went offline for two weeks because of internet issues but when it came back i found low battery alarm. The system has only the fridge and the battery bank is big (2X 25.5 200Amphrs victron batteries). I don't expect any problem with this bank even for a week. But can anyone help me to interprete what happened on this days using the screenshot bellow
I can only guess here because it lacks of a bit more information about the whole system and all of its's devices. Most of the time low battery alarm is coming from the VE.Bus system, for example if the MultiPlus suddenly disconnects (for whatever reason) from either the BMS or the GX device and as a result goes into alarm state because it is missing voltage information.
And from your screenshot it is obvious that there was a sudden voltage drop. Unfortunately the screenshot doesn't tell from which device it is.
