On a boat there is victronenergy installation with cerbo GX box. This box is reporting following measurements as on the picture. The CONSO is measured on starboard engine battery and reporting continuously discharging, doesn’t matter engine on or off or even connected to the shore. It remain also continuously on 0% charged. I also noticed that the voltage of this battery drop overnight below 12V and sometimes below 11V whhich triggers low voltage alarm. When in the morning Solar starts delivering power, CONSO voltage is slowly growing again up to 13.9V. I also noticed that the entire 12V electrical circuit on board is powered by this CONSO battery which is strange, I would expect it should use Litium Battery. It seems that the inverter (Victron Multipus) is using Litium Bank for 220V only.
Can anybody advise what would be the correct behavior and maybe post a screenshot from your Victron display, especially the status of the Starboard (main engine battery, in my case 125Ah AGM) many thanks
