Hi I have (on my Victron Control Panel) the BLUE light on "Charger" and also on "Inverter" flashing, simultaneously with the YELLOW lights for BULK, ABSORPOTION and FLOAT. They are flashing continuously, even once I have flicked the switch from ON to OFF. In OFF mode my fridge is still on, so it is still supplying power. Usually when one flicks it to OFF all power supply ceases. Any ideas what this is and whether one can still use it? Thank sin advance for any knowledge you may have.
