I have checked setting on MV monitor and they are as it should be. When ever I go to marina I plug 220V to my boat so I assume that it is charging to 100% as I stay at the boat 10-12 hours. Strange thing is that it never shows negative value, even when I am only on batteries, the remanning time is all the time CCCC that is strange as well. The remaining Ah is number higher than 1000, and I have 440Ah of batteries. On my previous boat I had AMG 400Ah batteries and Mastervolt monitor that worked perfectly (showing Ah, Voltage, Current drain, ..., including voltage of starting battery as well). I know the importance of the charging AMG batteries (currently on my Amel). Indication is that most likely monitor have failed.
